Description

  The present invention relates to cloth-like disposable personal care articles useful for cleansing and / or treating similar keratin-containing tissues on the skin, hair, and body surface in need thereof, and more particularly fibrous A disposable cleansing article comprising a treatment composition and / or a cleansing composition applied to the nonwoven fibrous web together with a nonwoven web.

  Personal care products have traditionally been sold in various forms such as soap bars, creams, lotions, and gels. These personal care products have been tried to meet a number of criteria to be acceptable to consumers. These criteria include cleansing effectiveness, feel, low irritation to skin, hair and eye mucous membranes, and sufficient foam volume. An ideal personal care product should gently cleanse, treat, or condition the skin or hair, cause little or no irritation, and should not excessively dry the skin or hair after frequent use. Personal care products often hold fibrous cleansing formulations or fibrous nonwoven webs or other devices (e.g., washcloths) that are used to hold cleansing formulations or provide separate cleansing, treatment, or conditioning formulations to the skin or hair. , Loofah, scrub towels, mesh mesh, etc.) or sold in the form of such products.

  Conventional forms of personal care cleansing products and articles can be very useful in providing effective cleansing and foaming. However, such conventional products and articles do not simultaneously provide other desirable agents that provide skin or hair benefits. One solution to this problem is to use separate cleansing products / products and treatment products / products. However, this is not always convenient or practical and many consumers prefer the use of a single article that can cleanse and treat the skin or hair. In typical personal care products, treatments such as skin conditioners are often incompatible with cleansing surfactants, resulting in undesirable inhomogeneous mixtures and are difficult to formulate. Formulators add emulsifiers, thickeners, and gelling agents to suspend the conditioning ingredients in the surfactant mixture to obtain a homogeneous mixture of the treatment product, such as a conditioner, and the surfactant. Make it cloudy. The resulting composition is a visibly homogeneous mixture, but the conditioner does not effectively deposit on the skin or hair because the conditioner emulsifies and is not released efficiently during cleansing. In addition, many treatment agents have a drawback of suppressing the generation of bubbles. Foam suppression is a problem because many consumers seek cleansing products that provide a rich creamy foam.

  Thus, conventional personal care products and articles that attempt to combine surfactants with other skin and hair treatments have drawbacks inherently due to incompatibility between the surfactant and such treatments. I understand that. There is clearly a need for the development of a personal care system that can provide effective cleansing, effective foamability, and always provide adequate hair and skin treatments with a single product. In addition, there is a need for personal care products that provide unit dose, exfoliation, and flexibility that can be handled in a manner that does not scatter the personal wash site.

  The personal care product of the present invention is convenient to use because it is in the form of either a single-use personal care product or a multi-use disposable product useful for cleansing and therapeutic or aesthetic benefit agent applications. Disposable items are convenient because they do not have to carry the cumbersome bottles, solids, jars, tubes, and other forms of cleansing, treatment, and conditioning items. Also, sponges, wash cloths or other cleansing devices that are intended to be reused over and over will cause bacteria to grow in connection with repeated use, produce an unpleasant odor, and produce other undesirable characteristics. Thus, disposable items are also a more hygienic alternative to using such tools. Fibrous webs are well known in the art. For example, fibrous nonwoven webs, such as webs formed from polymer fibers, are well known as useful materials for disposable products such as the surface layer on absorbent articles such as diapers. In a preferred embodiment of the present invention, the article is suitable for personal care applications and cleanses and / or therapeutically treats skin, hair, and similar keratin containing surfaces in need of such treatment. Useful for.

  In many applications, it is desirable for the fibrous web to have a bulky appearance and / or flexibility. For example, fabrics known as terry fabrics have a bulky appearance and flexibility and are often used in bath towels, wipes, bibs, clothing, and upholstery fabrics. Terry cloth is woven on a special loom such as a rapier loom. Terry fabrics are characterized by tufted loops of yarn and can vary the number of tuft loops and the loop density. However, terry fabrics are relatively expensive because they require relatively complex and expensive looms to manufacture. Because of its cost, terry fabrics are not commercially viable for many applications, particularly those intended for limited use, such as disposable absorbent articles.

  Attempts have been made to produce fibrous nonwoven web fabrics having the appearance of terry fabrics. For example, US Pat. No. 4,465,726 and US Pat. No. 4,379,799 (both Holmes et al.) Are perforated produced by fluid entanglement of fibers on a special shaped belt. And a ribbed, non-woven fibrous nonwoven web fabric. Even though pores can be avoided with the method disclosed in the Holmes et al. Patent, fluid entanglement is well known to be a relatively expensive process for the production of fibrous nonwoven webs, particularly webs for disposable items. is there. Furthermore, because the web formed by fluid entanglement is typically exposed to fluid forces in all areas of the web, the entire web receives the mechanical energy of the applied fluid force.

  The present invention relates to disposable personal care products that are particularly useful for cleansing and / or treating skin, hair, and similar keratin-containing tissues or other body surfaces in need of such treatment. Each such article includes a fibrous nonwoven web having a first surface and a second surface and including a first region and a plurality of discontinuous integral second regions, the second region comprising: Each of the articles further includes: a discontinuous portion having a linear orientation; and a deformed portion including a plurality of tuft-like fibers that are integral with the first region but extend from the first region. Includes a personal care composition associated with the web.

  In addition, these products are suitable for use in or in conjunction with another personal care device designed for a wider range of applications. In this case, the article of the present invention is placed in or attached to a separate personal care device that is not easily disposable, such as a bath towel or wash cloth. In addition, the disposable article of the present invention may be removably attached to a handle or grip suitable for cleansing and / or moving the article over the surface to be treated. The article of the invention is suitable for personal care applications in a preferred embodiment, but likewise the surface or area requires cleansing and / or benefit agents such as waxes, conditioners, UV protection agents, And other other applications that require the application of other similar applications, such as car care, marine transportation care, domestic care, animal care, etc., may also be useful.

FIG. 1 shows a web 1 of the present invention. The web 1 has a first surface 12 and a second surface 14 and is generally planar having a machine direction (MD) and a cross machine direction (CD) as is generally known in the art of fibrous nonwoven webs. And a two-dimensional fibrous nonwoven precursor web 20 (see FIG. 7). The first surface 12 corresponds to the first “side” of the web 1, the second surface 14 corresponds to the second “side” of the web 1, and the term “side” refers to paper and film It is used in the general usage of a generally two-dimensional web such as In all embodiments, the precursor web 20 is a fibrous nonwoven web and is composed of randomly oriented fibers, ie, fibers that are essentially randomly oriented with respect to at least MD and CD.

In addition, the deformation can be a tuft that can include looped or non-looped regions.

  As used herein, the term “fibrous nonwoven web” is repeated as in the case of woven or knitted fabrics with individual fibers or yarns incorporated therein, but with oriented fibers. It refers to a web having a structure that is not a pattern. Fibrous nonwoven webs or fabrics are not necessarily limited to these by many methods including melt blowing, span bonding, air laying, hydroentanglement, span lacing, and bonded card web methods. Has been formed. The basis weight of a nonwoven web fabric is usually expressed in grams per square meter (gsm), and the fiber diameter is usually expressed in μm. Fiber size can also be expressed in denier. The basis weight of the precursor web 20 (see FIG. 7) can range from 10 gsm to 500 gsm, preferably from about 16 gsm to 150 gsm, more preferably from about 25 gsm to about 120 gsm, and even more preferably from about 35 gsm to about 100 gsm. When used as a bath towel, a basis weight of 125 gsm to 250 gsm may be appropriate. The constituent fibers of the precursor web 20 of the fibrous nonwoven web can be composed of a polymer and can be composed of single component fibers, multicomponent fibers, and / or multicomponent fibers, capillary fibers, hollow fibers, split fibers, molded fibers or It can be a lobe-shaped fiber and can have a major cross-sectional dimension in the range of 0.1-500 μm (eg, a diameter for circular fibers). For example, one type of fiber suitable for nonwoven webs includes nanofibers. Nanofibers are described as fibers having an average diameter of less than 1 μm. Nanofibers can constitute all the fibers in the nonwoven web or some of the fibers in the nonwoven web. In addition, the constituent fibers of the precursor web may be a mixture of different types of fibers having different characteristics such as chemical properties, constituent components, diameters, and shapes. The constituent fibers can range from about 0.1 denier to about 100 denier. The crepe nonwoven layer may include various natural and synthetic fibers or materials. As used herein, “natural” means that the material is derived from plants, animals, and insects, or from by-products of plants, animals, and insects. Conventional base starting materials are usually fibrous webs comprising any common synthetic or natural fabric length fibers, or combinations thereof. Non-limiting examples of natural materials useful in the present invention include, but are not limited to, rayon fibers, silk fibers, keratin fibers, and cellulose fibers. Non-limiting examples of keratin fibers include those selected from the group consisting of wool fibers, camel hair fibers, and the like. Non-limiting examples of cellulose fibers include those selected from the group consisting of wood pulp fibers, cotton fibers, hemp fibers, burlap fibers, flax fibers, and combinations thereof.

For these and other suitable fibers and nonwovens prepared therefrom, see Riedel, “Nonwoven Bonding Methods and Materials”, Nonwoven World (1987), USA It is generally described in The Encyclopedia Americana, Vol. 11, pages 147-153 and Vol. 26, pages 566-581 (1984).

  As used herein, “spunbond fibers” are extruded from a plurality of normally circular microcapillaries of a spinneret with the diameter of the extruded filaments, and then rapidly shrink as a filament and then rapidly shrink. This refers to a fiber having a small diameter, which is formed by the process. Spunbond fibers are generally not tacky when deposited on a collection surface. Spunbond fibers are generally continuous and have an average diameter (from at least 10 samples) of greater than 7 μm, more specifically about 10-40 μm.

  As used herein, the term “melt blowing” refers to the passage of molten thermoplastic material through a capillary tube of a plurality of fine molds, usually circular, and as a molten thread or filament, at high speed, usually heated. Refers to the process by which the fiber is formed by extruding it into a focused stream of gas (eg air), which reduces the diameter of the melted thermoplastic material by thinning the filament. May be the diameter of the microfiber. Thereafter, the meltblown fibers are carried by the high velocity gas stream and are often still sticky on the collecting surface to form a randomly dispersed web of meltblown fibers. Meltblown fibers are microfibers that may be continuous or discontinuous and generally have an average diameter of less than 10 μm.

  As used herein, the term “polymer” generally includes, but is not limited to, homopolymers, copolymers, such as block, graft, random, and alternating copolymers, terpolymers, and the like. As well as blends and modifications thereof. In addition, unless otherwise limited, the term “polymer” includes all possible geometrical configurations of the material. This arrangement includes, but is not limited to, isotactic, atactic, syndiotactic and random symmetries.

  As used herein, the term “single component” fiber refers to a fiber formed from one or more extruders using only one polymer. This is not intended to exclude fibers formed from a single polymer with a small amount of additives added for coloring, antistatic properties, lubrication, hydrophilicity, and the like. These additives, such as titanium dioxide for coloring, are generally present in an amount of less than about 5% by weight, more typically less than about 2% by weight.

  As used herein, the term “bicomponent fiber” refers to a fiber formed by extruding at least two different polymers from separate extruders and spinning together to form one fiber. . The polymers are placed in discrete regions that are positioned approximately constant across the cross-section of the bicomponent fiber and extend uninterrupted along the length of the bicomponent fiber. Such a bicomponent fiber configuration may be, for example, a sheath / core arrangement in which one polymer is surrounded by the other polymer, or a side-by-side arrangement, a pie-type arrangement, or a “sea island type” It may be an arrangement. Bicomponent fibers can be split, and such fibers can be split longitudinally before or during processing into a large number of fibers each having a smaller cross-sectional dimension than the original bicomponent fiber It is. Split fibers have been shown to create softer nonwoven webs because of their reduced cross-sectional dimensions. Exemplary split fibers useful in the present invention include all types T-502 and T-512 16 segment PET / available from Fiber Innovation Technology, Johnson City, Tennessee. Nylon 6, 2.5 denier fibers, as well as type T-522 16 segment PET / PP split fibers are included.

  As used herein, the term “conjugate fiber” refers to a fiber formed by extruding at least two polymers from separate extruders and spinning together to form one fiber. Conjugate fibers are also sometimes referred to as multicomponent or bicomponent fibers. The conjugate fiber may be a single component fiber, but the polymers are usually different from each other. The polymers are placed in discrete areas that are positioned approximately constant across the cross-section of the conjugate fiber and extend uninterrupted along the length of the conjugate fiber. Such a conjugate fiber configuration may be, for example, a sheath / core arrangement in which one polymer is surrounded by the other polymer, or a side-by-side arrangement, a segmented arrangement, or “sea islands” It may be a “type” arrangement. In the case of bicomponent fibers, the polymers may be present in 75/25, 50/50, 25/75, or any other desired ratio.

  As used herein, the term “multi-component fiber” is used herein according to the art recognized meaning, as is the term “domain”. Multi-composition fibers are understood to include fibers comprising at least two polymers dispersed within the domain as at least one discontinuous phase throughout another polymer provided in the form of a continuous phase. Multi-composition fibers are further understood to include fibers comprising at least two or more polymers dispersed within the domains, and such dispersion may be random.

  As used herein, the term “bicomponent fiber” refers to a fiber formed by extruding two polymers from the same extruder as a blend. Bicomponent fibers do not have various polymer components that are arranged in separate regions that are positioned relatively constant across the cross-sectional area of the fiber, and the various polymers typically extend along the entire length of the fiber. Instead of being continuous, instead they form fibrils that usually start and end randomly. Bicomponent fibers may also be referred to as multicomponent fibers.

  As used herein, the term “capillary tract fiber” refers to a fiber having a capillary tract. Such a fiber can be, for example, a hollow fiber, but is preferably a fiber having a capillary channel on its outer surface. The capillary channel can have various cross-sectional shapes such as “U-shaped”, “H-shaped”, “C-shaped”, and “V-shaped”.

  As used herein, the term “integral” as “integral extension” when used with respect to the second region 4 refers to the fibers of the second region 4 originating from the fibers of the precursor web 20. The web includes at least four integral discrete second regions per square centimeter. Thus, for example, the looped fibers 8 of the deformable portion 6 can be plastically deformed and expanded fibers of the precursor web 20 and are therefore integral with the first region 2 of the web 1. As used herein, “monolithic” is distinct from fibers introduced or added to a separate precursor web for the purpose of making tufts, such as is commonly practiced in conventional carpet manufacturing. Should be. A suitable nonwoven web 20 should contain fibers that are capable of sufficient plastic deformation and tensile elongation so that looped fibers 8 are formed, or that sufficient movement of the fibers is possible. I can understand. However, it will be appreciated that a certain percentage of the fibers protruding from the plane of the first surface 12 of the precursor web 20 will not form a loop, but will instead break to form a broken end. Such fibers are referred to herein as “unwound” or “broken” fibers 18 as shown in FIG. Unraveled fiber ends 18 may also arise as a result of forming the deformed portion 6 from a nonwoven web consisting of or containing cut short fibers. The unraveled fiber ends 18 are not necessarily undesirable for the present invention, but when the deformed portion 6 mainly contains up to about 100% by weight of the looped fibers 8, the web 1 more easily has its bulky and soft properties. It is thought that it can be retained. In a preferred embodiment, at least 5%, preferably at least 10%, more preferably at least 20%, more preferably at least 30%, more preferably at least 40%, more preferably at least 5%, by weight of the fibers protruding in the Z direction. Is at least 50% by weight, more preferably 70% by weight, and still more preferably 90% by weight, of the looped fibers 8.

  A representative variant 6 of the embodiment of the web 1 shown in FIG. 1 is shown in a further enlarged view of region 2 in FIG. As shown, the deformed portion 6 includes a plurality of substantially aligned loop-like fibers 8, with the result that the deformed portion 6 has a well-defined longitudinal orientation and a longitudinal axis L. As used herein, the term “longitudinal” refers to a line, axis, or direction in the plane of the deformable portion 6 that is aligned with the longest dimension of the deformable portion 6. The deformable portion 6 also has a horizontal axis T generally orthogonal to the longitudinal axis L in the MD-CD plane (see FIG. 4). In the embodiment shown in FIGS. 1 and 2, the longitudinal axis L is parallel to the MD. In one embodiment, all of the spaced apart deformations 6 have longitudinal axes L that are generally parallel. The number of deformed portions 6 per unit area of the web 1, that is, the surface density of the deformed portions 6 is at least one deformed portion 6 per square centimeter, preferably at least four deformed portions 6 per square centimeter, more preferably It can include at least 10 deformations 6 per square centimeter, more preferably at least 20 deformations 6 per square centimeter, and more preferably at least 30 deformations 6 per square centimeter. In general, the surface density of the deformed portion 6 does not need to be uniform over the entire area of the web 1, but the deformed portion 6 may be formed in a web like a region having a predetermined shape such as a line, stripe, band, or circle. It can be placed only in one specific area.

  As shown in FIG. 2 and more clearly shown in FIGS. 3 and 4, one of the features of the fibers 8 of the deformed portion 6 in one embodiment of the web 1 is that the looped fibers 8 in the loop. It is an alignment with a remarkable directionality. As shown in FIGS. 3 and 4, the loop-like fibers 8 are substantially uniformly aligned with the horizontal axis T when viewed in a plan view as shown in FIG. 4. By “looped” fiber 8 is meant a fiber 8 that begins and ends in the web 1. “Aligned” with respect to the loop-like fibers 8 of the deformable portion 6 means that each loop-like fiber 8 has a significant vector component parallel to the horizontal axis T when viewed in a plan view as shown in FIG. It means that all the looped fibers 8 are generally oriented so as to have a main vector component parallel to the horizontal axis T. As used herein, a looped fiber 8 oriented at an angle greater than 45 degrees from the longitudinal axis L when viewed in a plan view as in FIG. 4 has a significant vector component parallel to the transverse axis T. . As used herein, the looped fiber 8 oriented at an angle greater than 60 degrees from the longitudinal axis L when viewed in a plan view as in FIG. 4 has a main vector component parallel to the transverse axis T. The deformation part may include up to about 100% of a main vector component parallel to the horizontal axis T. In a preferred embodiment, at least 1%, preferably at least 5%, more preferably at least 10%, more preferably at least 20%, more preferably at least 30%, more preferably at least 1% by weight of the fibers 8 of the deformed portion 6. Is at least 40% by weight, more preferably at least 50% by weight, more preferably at least 70% by weight, more preferably at least 90% by weight of the significant vector component, more preferably the main vector component, parallel to the horizontal axis T. Have. The orientation of the fibers can be determined using a magnifying means such as a microscope with a suitable measurement scale, if necessary. In general, in a non-linear portion of the fiber viewed in plan view, a linear approximation for both the longitudinal axis L and the looped fiber 8 can be used to determine the angle of the looped fiber 8 from the longitudinal axis L. .

  When the orientation of the loop-like fibers 8 in the deformed portion 6 in the second region 4 is compared with the composition and orientation of the fibers in the first region 2, the first region 2 is a precursor web 20 of a fibrous nonwoven web. , Best represented as having an essentially randomly oriented fiber alignment.

  In the embodiment shown in FIG. 1, the longitudinal axis L of the deformable portion 6 is generally aligned with the MD. The deformation 6 and thus the longitudinal axis L can in principle be aligned in any orientation with respect to the MD or CD. Therefore, in general, for each deformed portion 6, the looped aligned fibers 8 have a significant vector component parallel to the horizontal axis T, more preferably a main vector component parallel to the horizontal axis T. It can be said that the fibers 8 are aligned substantially perpendicular to the longitudinal axis L.

  FIG. 5 is a scanning electron microscope (SEM) photograph of a web 1 similar to that described with respect to FIG. The web 1 of FIG. 5 is a 70 gsm spunbond fibrous nonwoven web comprising polyethylene / polypropylene (sheath / core) bicomponent fibers. The viewpoint in FIG. 5 is basically a side view of the first surface 2 and the deformed portion 6 of the web 1. The “side view” is that the photograph of FIG. 5 is taken generally in the CD direction shown in FIGS. 1 to 4, and the longitudinal axis L of the MD and each deformed portion 6 is the same as FIG. ) Means being oriented across. As shown in FIG. 5, the deformed portion 6 including the looped aligned fibers 8 is aligned substantially perpendicular to the longitudinal axis L and has a significant vector component at least parallel to the transverse axis T.

  In some embodiments, another feature of the deformable portion 6 is that the open cavity region 10 (FIG. 2) defined within the deformable portion 6 is due to a preferred method of forming the deformable portion 6 as described below. And a generally open structure of the deformation 6 characterized by The cavity region 10 may be wider or larger at the distal three ends of the deformed portion 6 and narrower at the base 5 of the deformed portion 6. This shape is the opposite of the tooth shape used to form the deformed portion 6. “Cavity area” does not mean that it contains no fibers, but is intended as a general description of its overall appearance. Therefore, in some deformed portions 6, one or more unraveled fibers 8 may exist in the cavity region 10. An “open” cavity region is one in which the two longitudinal ends of the deformed portion 6 are generally open and do not contain fibers, resulting in the deformed portion 6 having a “tunnel” structure as shown in FIG. It means to form. For example, FIG. 6 is an enlarged SEM view of one deformed portion 6 of the web 1 shown in FIG. As shown, in addition to the looped aligned fibers 8, there is a clear open cavity region 10 defined by the looped aligned fibers 8. Only a few broken fibers 18 can be seen. As can be seen, the base 5 of the deformable portion 6 may be closed (for example, the fibers forming the deformable portion 6 are in close contact with each other) or may remain open. In general, the openings at the base 6 are both narrow.

  In addition, as a result of the preferred method of making the web 1, the second region 4 associated with the second surface 14 is directed directionally into the deformed portion 6 (ie, by the teeth of the forming structure detailed below) (ie, Of the second surface 14 protruding in the “Z direction” indicating an “out-of-plane” direction generally orthogonal to the MD-CD plane shown in FIGS. 1 and 3 as generally understood in the technical field of fibrous nonwoven webs. Discontinuity 16 results, which is characterized by a generally linear recess originally defined by random fibers. The abrupt change in orientation indicated by the pre-randomly oriented fibers of the precursor web 20 exhibits a linearity that can be described as having a longitudinal axis that is generally parallel to the longitudinal axis L of the deformed portion 6. 16 is defined. Due to the nature of many fibrous nonwoven webs useful as the precursor web 20, the discontinuities 16 may not be clearly seen, for example, as deformed portions 6. For this reason, the discontinuities 16 on the second side of the web 1 may end up unnoticeably and may generally not be detected unless the web 1 is rigorously inspected. Thus, in some embodiments, the web 1 has the look and feel of a terry cloth, and in some embodiments, the web 1 has a terry cloth appearance on a first side. And has a relatively smooth and soft look and feel on the second side.

  Furthermore, as a result of the preferred method of making the web 1, regardless of whether the second region 4 has looped aligned fibers 8, each precursor web has a first surface 12 and a second surface of the web 1. Each of 14 shows remarkable linearity at or near the same. As disclosed in more detail below with respect to the fabrication method, the geometry of the teeth 110 of the roll 104 of FIG. 7 allows the deformations 6 of the second region 4 of the precursor web 20 and their corresponding discontinuities. It can be seen that the 16 have linear orientations associated with them. This linear orientation is an inevitable result of the method of making web 1 described herein. One way to understand this linear orientation is to consider the linear orientation of the discontinuities 16 on the second surface 14 of the web 1. Similarly, when the deformed portion 6 is cut from the web 1 at the first surface 12, the second region 4 is, for example, as if a straight slit or cut was made in the precursor web 20 at the location of the deformed portion 6. Will appear as linear discontinuities on the first surface 12 of the web 1. This linear web discontinuity coincides longitudinally with the longitudinal axis L.

  From the description of the web 1, it can be seen that the loop-like fibers 8 of the deformable portion 6 can extend from either the first surface 12 or the second surface 14 of the web 1. Needless to say, the fibers 8 of the deformation 6 can also extend from the interior 18 of the web 1. The fibers 8 of the deformed portion 6 extend as a result of jumping out of a generally two-dimensional plane of the precursor web 20 (ie, jumping out in the “Z direction” as shown in FIG. 3). In general, the fibers of the second region 4 include fibers extending from the fibers of the first region 2 that are integral with the fibers of the first region 2 of the fibrous web.

  Thus, from the foregoing description, in one embodiment, the web 1 can be described as a fibrous web 1 having a first surface 12 and a second surface 14, wherein the fibrous web 1 comprises a first region 2 and a plurality of regions. At least one portion including a discontinuous integral second region 4, wherein the second region 4 is a discontinuous portion 16 that exhibits a linear orientation and that defines a longitudinal axis L; It is understood that it has at least another part which is a deformed part 6 that is integral with the region 2 and includes a plurality of tufted fibers extending from the first region 2.

  The extension of the looped fiber 8 may be accompanied by an overall reduction in fiber cross-sectional dimensions (eg, round fiber diameter) due to the effects of plastic deformation and Poisson's ratio of the fiber. Accordingly, the fibers 8 of the deformable portion 6 may have an average fiber diameter that is smaller than the average fiber diameter of the fibers of the precursor web 20 as well as the fibers of the first region 2, and specifically it will reduce the fiber diameter. Shown is the portion of the fiber loop between the distal and proximal portions. The same fiber is also present in the first region and has the original fiber diameter at that point. It is believed that this reduction in fiber diameter can contribute to the perceived softness or texture of the web 1, and depending on the material properties of the precursor web 20, can contribute to a softness comparable to a terry cotton fabric. It has been found that the fiber cross-sectional dimension reduction is greatest in the middle between the base 5 and the distal portion 3. This is believed to be due to the fabrication method, as disclosed in more detail below. Briefly, the portion of the fiber at the base 5 and distal portion 3 of the deformable portion 6 is adjacent to the tip of the tooth group 110 of the roll 104, as will be described in more detail below, during processing. Fixed by friction and stuck. Therefore, the intermediate portion of the deformed portion 6 is more easily stretched or stretched, and thus tends to cause a corresponding decrease in fiber cross-sectional dimension.

  It is understood that a preferred precursor web 20 suitable for the web 1 of the present invention should contain fibers capable of undergoing sufficient plastic deformation and tensile elongation so that looped fibers 8 are formed. Can do. However, it will be appreciated that a certain percentage of the fibers that protrude from the plane of the first surface 12 of the precursor web 20 will not form a loop, but instead will break to form a broken end. Such fibers are shown as the fiber ends 18 unraveled in FIGS. Referring to FIG. 7, an apparatus and method for making the web 1 of the present invention is shown. The apparatus 100 includes a pair of meshing rolls 102 that rotate about axis A and rolls 104 that rotate about axis B, which are parallel in the same plane. The roll 102 includes a plurality of raised portions 106 and a groove group 108 corresponding to the plurality of raised portions 106 that extend around the entire circumference of the roll 102 without interruption. The roll 104 is similar to the roll 102 but does not have a ridge that extends uninterrupted around the entire circumference, but rather circumferentially spaced teeth that extend in a spaced relationship about at least a portion of the roll 104. It includes multiple rows of circumferentially extending ridges that have been modified to be 110 rows. Individual rows of teeth 110 of roll 104 are separated by corresponding grooves 112. During operation, the rolls 102 and 104 mesh so that the raised section group 106 of the roll 102 extends into the groove group 112 of the roll 104 and the tooth group 110 of the roll 104 extends into the groove group 108 of the roll 102. The engagement is shown in more detail in the cross-sectional view of FIG. 8, which will be described later. Either or either of the rolls 102 and 104 can be heated using means known in the art, such as a hot oil filled roller, or the roller can be electrically heated.

  In FIG. 7, the apparatus 100 is shown in a preferred configuration having one patterned roll, eg, a roll 104 and one unpatterned and grooved roll 102. However, in certain embodiments, it may be preferable to use two patterned rolls 104 having the same or different patterns in the same or different corresponding areas of each roll. Such an apparatus can produce a web with deformed portions protruding from both sides of the web 1.

  A method of making the web 1 of the present invention in a commercially feasible continuous process is depicted in FIG. The web 1 is made by mechanical deformation of a precursor web 20 that can be described as being generally planar and two-dimensional. The terms “planar” and “two-dimensional” are simply compared to the finished web 1 given a clear out-of-plane, ie, three-dimensionality in the Z direction due to the formation of the second region 4. Means the web is flat. “Planar” and “two-dimensional” are not intended to provide any particular flatness, smoothness, or dimension.

  The precursor web 20 is provided directly from the web making process or indirectly from the feed roll (both not shown) and moves in the machine direction to the nip 116 of the counter-rotating meshing rolls 102 and 104. Is done. Without being bound by theory, the precursor web can be of any known type, including monocomponent fibers, bicomponent fibers, and / or bicomponent fibers, capillary channel fibers, hollow fibers, molded fibers, or lobe fibers. It can be a nonwoven web comprising any of the fibers and can have a major cross-sectional dimension (e.g., diameter for circular fibers) in the range of 5 to 500 [mu] m. The precursor web 20 can be preheated by means known in the art, such as heating on an oil heated roller. Further, the precursor web may be a fibrous nonwoven web made by a known method such as a meltblown method, a spunbond method, or a bonded card web method. As the precursor web 20 passes through the nip 116, the teeth 110 of the roll 104 enter the grooves 108 of the roll 102 and simultaneously cause the fibers to jump out of the plane of the precursor web 20 to form the deformed portion 6. Form. In practice, the teeth 110 will “push” or “punch” the precursor web 20. As the tip of the tooth group 110 pushes out the precursor web 20, the fibers are stretched or plastically deformed or broken to form the second region 4 including the looped fibers 8 of the deformed portion 6 of the web 1. Until then, the portion of the fiber that straddles the tooth group 110 oriented mainly in the CD is pushed out of the surface of the precursor web 20 in the Z direction by the tooth group 110. The fibers oriented mainly parallel to the longitudinal axis L, i.e. oriented in the machine direction of the precursor web 20 shown in FIG. 1, are simply spread by the teeth 110, substantially in the first region 2 of the web 1. Remain in. As will be described in more detail below, it has been found that the formation rate of the deformed portion 6 generally affects the fiber orientation at least at a slow formation rate, as described above with reference to FIGS. It can be seen why the looped fibers 8 can exhibit a unique fiber orientation with a high percentage of fibers having a significant vector component or main vector component parallel to the transverse axis T of the deformation 6. In general, at least some of the fibers of the deformed portion 6 are loop-like aligned fibers that can be described as having significant vector components or principal vector components parallel to a plane oriented in the Z direction orthogonal to the transverse axis T. 8.

  The number, spacing, and size of the deformable portions 6 are varied by changing the number, spacing, and size of the teeth 110 and correspondingly performing the necessary dimensional changes on the roll 104 and / or roll 102. be able to. This change and the possible changes in the precursor web 20 and line speed allow a wide variety of webs 1 to be made for many purposes.

  FIG. 8 shows a section of some of the interlocking rolls 102 and 104 and the ridge 106 and tooth group 110. As shown, the tooth group 110 has a tooth height TH (TH can also be applied to the height of the ridge. In a preferred embodiment, the tooth height is equal to the height of the ridge), and It has a tooth-to-tooth space (or a space between the raised portion and the raised portion) called a pitch P. As shown in the figure, the engagement depth E is an index of the degree of meshing between the rolls 102 and 104 and is measured from the tip of the raised portion 106 to the tip of the tooth 110. The engagement depth E, tooth height TH, and pitch P can be varied as desired, depending on the properties of the precursor web 20 and the desired characteristics of the web 1. For example, in general, the greater the degree of engagement E, the greater the required stretch characteristics that the fibers of the precursor web 20 should have when primarily loop-shaped deformations are desired. Also, the greater the density of the desired second region 4 (the density of the second region 4 per unit area of the web 1), the smaller the pitch should be, and the tooth length TL and tooth distance will be described later. TD should be small.

  FIG. 9 shows a plurality of teeth 110 useful for making a terry woven web 1 of spunbonded fibrous nonwoven web material from a precursor web 20 having a basis weight of about 60 gsm to 100 gsm, preferably about 80 gsm. 1 illustrates one embodiment of a roll 104 having An enlarged view of the tooth group 110 is shown in FIG. In this embodiment of the roll 104, the teeth 110 have a uniform circumferential length dimension TL of approximately 1.25 mm, measured generally from the leading edge LE to the trailing edge TE at the tooth tip 111, and are circumferentially relative to each other. Are evenly spaced by a distance TD of about 1.5 mm. To make a terry fabric web 1 from a precursor web 20 having a basis weight in the range of about 60-100 gsm, the teeth 110 of the roll 104 are preferably long in the range of about 0.5 mm to about 3 mm. TL, spacing TD of about 0.5 mm to about 3 mm, tooth height TH in the range of about 0.5 mm to about 10 mm, pitch of about 1 mm (0.040 inch) to 2.54 mm (0.100 inch) P. The engagement depth E can be about 0.5 mm to about 5 mm (maximum equal to the tooth height TH). Needless to say, E, P, TH, TD, and TL are independent of each other to achieve the desired size, spacing, and surface density of deformed portions 6 (number of deformed portions 6 per unit area of web 1). Can be changed.

  As shown in FIG. 10, each tooth 110 has a tip 111, a leading edge LE, and a trailing edge TE. The tooth tip 111 is elongated and has a generally longitudinal orientation corresponding to the longitudinal axis L of the second region 4. It is believed that LE and TE should be approximately perpendicular to the local peripheral surface 120 of the roll 104 in order to obtain a tufted and looped deformation 6 of the web 1 that can be described as a terry fabric. ing. Furthermore, the LE or TE transition from tip 111 should be at an acute angle, such as a right angle with a sufficiently small radius of curvature, so that tooth group 110 will pierce precursor web 20 at LE and TE. Without being bound by theory, the presence of a relatively sharp angle tip transition between the tip of the tooth 110 and LE and TE makes the tooth group 110 “clean”, ie, localized and unambiguous. It is believed that the body web 20 can be punched so that the resulting web 1 can be described in the second region 4 as, for example, “tufted” rather than “embossed”. When so processed, the web 1 is not given any particular elasticity beyond the elasticity that the precursor web 20 may originally have.

  The line speed, i.e., the speed at which the precursor web 20 is processed through the nip of the rotating rolls 102 and 104, and the resulting rate of formation of the deformed part 6, affects the structure of the resulting deformed part 6. Has been found to affect. For example, the deformation 6 shown in FIGS. 5 and 6 was made at a relatively slow speed of about 3 meters per minute (m / min) (about 10 feet per minute). 3 m / min is considered a relatively slow rate for commercial production for many consumer applications, but for spunbond bicomponent fibers used in the fibrous nonwoven webs shown in FIGS. The relatively slow speed results in a very uniform looped aligned fiber in the deformation 6.

  At higher line speeds, i.e., relatively high processing speeds through the nips of the rotating rolls 102 and 104, similar materials can exhibit very different structures for the deformations 6, i.e. tufts. For example, FIGS. 11 and 12 show a typical deformation 6 for a web 1 made from the same material and under the same processing conditions, the only difference being the rotational speed of the rolls 102 and 104, i.e. The line speed (unit: length / time) at which the precursor web 20 is processed into the web 1. The web shown in FIGS. 11 and 12 is 25 gsm available from BBA Fibrous, non-woven webs of Simpsonville, South Carolina, under the trade name Softspan 200 (registered) Trademark). The web shown in FIG. 11 has an engagement depth E of about 3.4 mm (about 0.135 inches), a pitch P of 1.524 mm (0.060 inches), and a tooth height TH of 3.912 mm (0 .154 inch), tooth distance TD was 1.588 mm (0.0625 inch) and tooth length TL was processed through nip 116 of rolls 102 and 104. The web was advanced at a line speed of about 15 meters / minute (about 50 feet per minute). The web shown in FIG. 12 was identical to the web shown in FIG. 11 and was processed under the same conditions except for a line speed of about 150 meters per minute (about 500 feet per minute).

  As can be seen by examining FIGS. 11 and 12, the illustrated deformed portion 6 is significantly different. The deformation part 6 shown in FIG. 11 is similar in structure to the deformation part shown in FIGS. That is, it shows a substantially aligned looped fiber 8 that is substantially free of broken fibers, such as the fiber 18 shown in FIG. However, the deformed portion 6 shown in FIG. 12 exhibits a very different structure, i.e. a structure that appears to be typical for a spunbonded fibrous nonwoven web material processed to form the deformed portion 6 at a relatively high speed. . Typical for this structure is a broken fiber between the proximal portion of the deformable portion 6, ie, the base 5, and the distal portion of the deformable portion 6, ie, the top portion, and the top of the deformable portion 6. It seems to be “entanglement” 7 of the fiber. The tangle 7 includes unbroken looped fibers 8 that are supported by the fibers 8 at the top of the deformed portion 6, and also a portion of the broken fibers 11 that are no longer integral with the precursor web 20. Including. That is, the tangle 7 was originally integral to the precursor web 20, but is completely pulled away from the precursor web 20 after being processed at a sufficiently high line speed in the process described with respect to FIGS. Including the fiber part.

  Thus, from the foregoing description, in one embodiment, the web 1 can be described as a fibrous web 1 having a first surface 12 and a second surface 14, wherein the fibrous web 1 comprises a first region 2 and a plurality of regions. A discontinuous second region 4, wherein the second region 4 is a discontinuous portion 16 that exhibits a linear orientation and defines a longitudinal axis L; At least one other portion, and the deformable portion 6 is integral with the first region 2 and extends from the first region 2, and the first region 2 is not integral with the first region 2. It is understood to include fibers that do not extend from region 2.

  Another example of a web 1 that is identical in material and processing except for line speed is shown with respect to FIGS. The precursor web 20 for each web 1 shown in FIGS. 13 and 14 is a trade name available from BBA Fibrous, non-woven webs, Simpsonville, SC. It was 60 gsm DAPP (ductile oriented polypropylene), sold as Softspan 200®. The web shown in FIG. 13 has an engagement depth E of about 3.4 mm (about 0.135 inches), a pitch P of 1.524 mm (0.060 inches), and a tooth height TH of 3.683 mm (0 .145 inch), tooth distance TD was 1.588 mm (0.0625 inch) and tooth length TL was machined through nip 116 of rolls 102 and 104. The web was advanced at a line speed of about 15 meters / minute (about 50 feet per minute). The web shown in FIG. 14 was identical to the web shown in FIG. 13 and was processed under the same conditions except for a line speed of about 150 meters per minute (about 500 feet per minute).

  The web 1 shown in FIG. 13 was processed at a line speed of about 15 meters per minute (about 50 feet per minute). As can be seen, even at this relatively moderate line speed, some amount of entanglement is seen at the distal end of the deformation 6. This entanglement appears to be a denser portion of flat compressed fiber and occurs at the portion of the deformed portion 6 associated with the tips of the teeth 110 of the roll 104. As the line speed increases, this entanglement, or entanglement 7, becomes more pronounced as shown in FIG. 14, which shows the same conditions as the web shown in FIG. A web processed at a line speed of about 150 meters per minute (about 500 feet per minute) is shown. The deformed portion 6 shown in FIG. 14 shows a clearer tangle 7, which is integral with the first region 2 and extends from the first region 2, and is not integral with the first region 2. It can be described as including fibers that do not extend from the first region 2.

  The clear fiber orientation observed at the distal portion of the deformed portion 6, such as tangle 7, is believed to be mainly due to the processing speed, and the fiber type, the basis weight of the precursor web 20, and the interfiber It is also believed to be affected by other parameters such as processing temperature that can affect bonding. For example, as observed above, fiber entanglement occurs at the portion of the deformed portion 6 associated with the tips of the teeth 110 of the roll 104. It is believed that the frictional engagement of the fiber at the tip of the tooth group “fixes” the fiber in place, thereby limiting fiber elongation and / or fiber mobility, and two mechanisms 6 is considered to be possible. Thus, after being locked in place, the fibers adjacent to the tips of the teeth 110 can be broken and broken by random entanglement of the precursor web and possible low temperature melting of the fibers by pressure and friction. The fiber remains in the tangle 7 at the distal end of the deformation 6.

  A precursor web 20 having a relatively high basis weight generally has a relatively high number of fiber portions in the tangle 7. In a sense, it appears that most of the fibers contained in the precursor web are simply displaced in the Z direction to the distal portion of the deformed portion 6 resulting in tangle 7. Precursor web 20 that includes fibers with relatively low elongation or fibers with relatively low mobility between fibers (eg, fiber reptation) will remain entangled 7 at the distal end of deformation 6. Seems to be relatively small. Mobility between fibers can be increased by reducing or eliminating interfiber bonding. In certain nonwoven webs, thermal bonding can be eliminated completely or greatly reduced to increase mobility between fibers. Similarly, the degree of entanglement of the hydroentangled web can be reduced to increase mobility between fibers. Any precursor web 20 can still increase inter-fiber mobility if a lubricant is applied prior to the processing disclosed herein. For example, a surfactant or mineral oil lubricant can be applied to the precursor web 20 prior to entering the nip 116 of the rolls 102 and 104.

  As a result of the presence of the tangle 7, a web 1 having a slightly rough texture is obtained which is useful, for example, in wipes where a more scrubbing texture is desired. In a sense, a soft terry cloth-like tactile web that is processed at a relatively low speed can result in the feel of a cheap hotel towel when processed at the same conditions but at a relatively high speed. There is. This rough texture feel may be useful in some applications such as hard surface cleaning wipes, facial exfoliating wipes, and skin cleansing wipes.

  Since certain bonded card webs containing short length fibers produce very few looped fibers 8 in the deformed portions 4, the deformed portions 6 created in these webs have been described above with respect to FIGS. It has been found that it cannot be described as including a plurality of loop-like aligned fibers 8. Instead, as shown in the SEM picture of FIG. 15, the carded fibrous nonwoven web has few, if any, looped aligned fibers 8 and many if not all aligned. A deformation 6 with fibers and / or broken fibers 18 can be produced. The precursor web 20 used to make the web 1 shown in FIG. 15 is obtained as a high elongation card web (HEC®) from BBA Nonwovens, Simpsonville, SC. A possible 40 gsm card web with an engagement depth E of about 3.4 mm (about 0.135 inches), a pitch P of about 1.5 mm (about 0.060 inches), and a tooth height TH of about 3. Nip of rolls 102 and 104 with 7 mm (about 0.145 inch), tooth distance TD about 1.6 mm (about 0.063 inch) and tooth length TL about 1.25 mm (about 0.050 inch) 116. The web was advanced at a line speed of about 15 meters / minute (about 50 feet per minute). The reason why the fibers in the deformed portion 6 made from the card web are not aligned is believed to be due in part to the nature of the fibers contained in the card web. Short fibers are not “endless”, but instead have a predetermined length on the order of 25 mm to about 400 mm, more typically about 40 mm to about 80 mm. Therefore, when the card web is processed by the apparatus described with respect to FIG. 7, the undissolved fiber ends are in the vicinity of the deformed portion 6, and therefore the possibility of creating non-looped fiber ends in the deformed portion 6 is much greater. It has been.

  Thus, from the foregoing description, the web of the present invention need not have looped aligned fibers, and in one embodiment, the web of the present invention has a first surface 12 and a second surface 14, and It can be described as being a fiber web 1 formed by selective mechanical deformation of the precursor web 20 comprising fibers that are substantially randomly oriented, the fiber web being substantially free of deformation due to selective mechanical deformation. Including a first region of substantially randomly oriented fibers and a plurality of discontinuous integral second regions, the second region 4 being spaced apart deformations of the precursor web 20 6 and each second region 4 is at least one portion that is a discontinuity 16 that exhibits linearity and defines a longitudinal axis L, and is integral to the first region but from the first region Contains multiple tufted fibers that extend It is understood and at least another portion.

  The web 1 of the present invention presents many opportunities to produce industrial materials with selected characteristics. For example, the web 1 can be produced by selecting the length of the short fibers in the carded precursor web 20 so that the probability of having exposed fiber ends in the deformation 6 can be reliably predicted. it can. Further, the short-fiber card web is spunbonded so that the deformed portion 6 of the second region 4 mainly includes loop-shaped spunbond fibers, and the first region 2 includes both card fibers and spunbond fibers. It can also be blended or laminated with a nonwoven web to create a hybrid. The fiber type, short fiber length, fiber layering, and other variables of the precursor web 20 can be varied as desired to provide the desired functional characteristics of the web 1.

  In a preferred embodiment, the precursor web 20 is a fibrous nonwoven web with minimal interfiber bonding. For example, the precursor web can be a fibrous nonwoven web having a pattern of discontinuous thermal point bonds, as is generally known in the fibrous nonwoven web art. The carded heat bonded web preferred for the present invention is lightly bonded. As used herein, the term “lightly bonded” means that the nonwoven web is sufficiently thermally bonded to melt the fusible fibers and provide web integrity for easy handling and transportation. However, it means that the web does not bind so severely that it loses its flexibility and flexibility. Within the carded thermally bonded web, light bonds are preferred for making tufts and loops.

  In general, however, it is desirable to minimize the number and spacing of bond points so that maximum fiber mobility and position movement is possible in the second region 4 of the web 1. In general, the use of fibers having a relatively large diameter and / or relatively large expansion to break and / or relatively large fiber mobility, the second region 4 better and more clearly formed, Specifically, the deformed portion 6 is provided.

  The web 1 is disclosed in the preferred embodiment as a single layer web made from a single layer precursor web 20, but this need not necessarily be the case. For example, a laminate or composite precursor web 20 having two or more layers or plies can be used. Recognizing that, in general, looped aligned fibers 8 formed, for example, from a precursor web of a laminate can be composed of fibers from both (or all) layers of the laminate, the foregoing description of web 1 Is true. Thus, in such a web structure, it is important that all fibers in all layers have sufficient diameter, stretch properties, and fiber mobility so that they do not break prior to expansion and deformation. In this method, fibers from all layers of the laminate may contribute to the tuft-like deformed portion 6. In a multi-layer web, the fibers of different webs may be mixed or mixed in the deformed portion 6. The fibers do not protrude through the adjacent web, but bond with the fibers of the adjacent web. This is often observed when the web is processed at very high speeds.

  The multilayer web 1 may have significant advantages over the single layer web 1. For example, a deformation 6 resulting from a multilayer web 1 using two precursor webs 20A and 20B is schematically shown in FIGS. As shown, both precursor webs 20A and 20B provide fibers to deformation 6 in a “nesting” relationship that “fixes” the two precursor webs together to provide adhesive or thermal bonding between the layers. A laminate web is formed without use or need. However, if desired, interlayer adhesives, chemical bonds, resin or powder bonds, or thermal bonds can be selectively used for specific regions or all of the precursor web. In the preferred embodiment, the deformable portion 6 retains the layered relationship of the precursor web of the laminate as shown in FIG. 16, and in all preferred embodiments, the upper layer (specifically, FIG. 16). The layer 20A of ˜18, but generally the uppermost layer in the Z direction shown in FIGS. 16 to 18) is maintained in a substantially intact state, and the loop-like fiber 8 shown in FIG. Form.

  In the multilayer web 1, each precursor web can have different properties. For example, the web 1 can include two (or more) precursor webs, eg, a first precursor web 20A and a second precursor web 20B. The first precursor web 20A can form an upper layer that exhibits high elongation and large elastic recovery that can cause the web 20A to bounce back. Bounce back helps to squeeze the base portion 5 of both web deformations 6 as shown in FIG. Further, the rebound or the lateral restriction is also useful for fixing and stabilizing the fibers oriented in the Z direction in the deformable portion 6. The lateral restriction provided by the precursor web 20A can also increase the stability of the second precursor web 20B. An example of the multi-layer web 1 includes a first precursor web 20A composed of a spunbond PE / PP (sheath / core) nonwoven web manufactured by BBA of Washougal, Washington. The second precursor web 20B is a thermally point bonded carded PET / Co-PET nonwoven web (50% 6dpf PET Wellman type 204 manufactured in Charlotte, NC, and Gastonia, NC). 50% 6dpf Co-PET pine type LM651). Since the second precursor web 20B can be loosely bonded to allow tufting, squeezing the first precursor web 20A laterally will also increase the stability of the second precursor web 20B. be able to. The multilayer web 1 can be used as a body-contacting layer when used as a topsheet on a disposable absorbent article, or as a lower layer placed between the topsheet and the absorbent core Can be used. Multilayer webs can also be used as the absorbent core.

  In the multilayer web 1, each precursor web can have different material properties, thereby imparting beneficial properties to the web 1. For example, two (or more) precursor webs, such as web 1 comprising a first precursor web 20A and a second precursor web 20B, may be on a disposable absorbent article, as will be described in more detail below. It can have beneficial fluid handling properties for use as a topsheet. For superior fluid handling, for example, the first precursor web 20A may form an upper layer (ie, a layer that contacts the body when used as a topsheet on a disposable absorbent article). In addition, the web 20A can be composed of relatively hydrophobic fibers. The second precursor web 20B is disposed between a top layer and an absorbent core when used on a lower layer (ie, a disposable absorbent article) composed of relatively hydrophilic fibers. Layer) can be formed. The fluid deposited on the upper, relatively hydrophobic layer is immediately carried to the lower, more hydrophilic layer. One of the reasons that rapid fluid transport is observed is the capillary structure formed by the generally aligned fibers 8, 18 of the deformation 6. The fibers 8, 18 form a directional aligned capillary between adjacent fibers, and the capillary action is enhanced by the overall collection of fibers near the proximal portion 5 of the deformed portion 6.

  Rapid fluid transport is further believed to increase by allowing fluid to enter the web 1 through the cavity 10 created by the deformation 6. This “side-to-side” ability and / or capillary action and / or the hydrophilic gradient provided by the structure of the web 1 make it an ideal material for optimal fluid handling for disposable absorbent articles. . Specifically, the multi-layer web 1 can provide even greater improvements in fluid handling properties.

  In other embodiments, the first precursor web 20A can be composed of relatively soft fibers (eg, polyethylene), while the second precursor web 20B is composed of relatively stiff fibers (eg, polyester). Can be configured. In such a multilayer web 1, the deformable portion 6 can maintain or recover a specific amount of height h even after pressure is applied.

  Depending on the precursor web 20 used and the dimensional parameters of the rolls 102 and 104 including the teeth 110, the web 1 of the present invention can exhibit a wide range of physical properties. The web 1 has a series of textures ranging from softness to roughness that are subjectively felt, absorbency ranging from non-absorbent to high absorbency, bulkiness ranging from relatively low bulk to relatively high bulk, low tear strength Tear strength ranging from high to high tear strength, elasticity ranging from inelastic to at least 100% elastic stretch, chemical resistance ranging from relatively low resistance to relatively high resistance depending on the chemicals considered, Shielding ability, alkali resistance, opacity, wiping ability, water absorption, oil absorption, moisture permeability, heat insulation properties, weather resistance, high strength, high tearing force, abrasion resistance, electrostatic control, texture, dye A wide variety of other parameters generally described as affinity, safety, etc. can be shown. In general, depending on the elongation characteristics of the fibers of the precursor web 20, the size of the apparatus 100 is changed so that the height h (shown in FIG. 20) and the spacing (including the surface density of the discontinuous second region 4) are included. Including the web 1 having a wide range of dimensions associated with the second region 4.

  19 is a terry cloth-like fibrous nonwoven web fabric web useful as a component of a disposable absorbent article made by the process of the present invention using the roll 104 shown in FIGS. 1 is a photomicrograph of 1.

The web 1 of FIG. 19 has about 24 deformations 6 per square centimeter, and more clearly shows a plurality of spaced tuft-and-loop deformations 6 having a plurality of loop-like aligned fibers 8. Each fiber 8 has an average fiber diameter of about 18 μm, folded at a visible folded edge for purposes of illustration.

As shown in FIG. 10, in the web described with respect to FIG. 20, the hollow region 10 of the tuft-and-loop deformation 6 is generally circular or elliptical and has a major dimension called height h. And the height h can be at least 1 mm. In general, the height is not considered critical to the functioning of the web, but can vary depending on the desired end use of the web 1. The height h can be from 0.1 mm to about 10 mm or more. A web 1 formed from a fibrous nonwoven web precursor web 20 and having the look and feel of a terry fabric should have a height h of about 1 mm to about 3 mm.

  In a further embodiment of the web 1 shown in FIG. 21, on the side of the web 1 associated with the first surface 12 of the web 1, the second region 4 can include deformations 6, each deformation 6 Includes a plurality of tufted aligned fibers 8 extending outwardly from the first surface 12.

And have. On the first surface 12 of the web 1, the second region 4 can include discontinuities 16 defined by fiber orientation discontinuities on the first surface 12 of the web 1.

(Method for evaluating tuft characteristics)
Select a representative portion of the web side and prepare the web sample to be suitable for evaluation by scanning electron microscope (SEM) imaging to create an image or photomicrograph by standard procedures well known to those skilled in the art To do. First, an image is captured at a relatively low magnification of about 10 times, and a field of view including a tuft is selected. Several representative tufts are selected within the field of view and images are acquired at several viewing angles to enhance the ability to count the fibers contained in the selected tufts. From each selected tuft facing the machine direction, at least a first image is obtained looking through the open end of the tuft at a low angle from the surface. At least a second image is obtained at an angle rotated nearly 90 degrees from the first image. The magnification is selected to increase the ability to accurately count the fibers in the tuft and measure the diameter of the fibers. If a representative portion of the bulk is not seen in the already acquired image, an image of the bulk surface away from the tuft is also obtained for comparison. When images are printed 20 mm x 25 mm (8 inches x 10 inches) and measurements are taken with a 15 cm (6 inches) caliper, suitable magnifications are typically in the range of about 10 times to about 100 times. The image is printed in a size of 20 mm × 25 mm (8 inches × 10 inches) or more. This is a photomicrograph. Include a scale bar in each printed image.

(Fiber count)
Examine the photomicrograph of the tufts to be counted. Select a micrograph of the tuft looking through the open area of the tuft. If the open area of the tuft is not clear, select an image that can count fibers. Tufts are made up of fibers that rise from the web surface at one point, and some fibers may loop back and enter the surface at another point. Look for a tufted area where the upward and downward portions of the same fiber can be easily distinguished to reduce as few unclear fibers as possible.

  Count the number of fibers using a pencil, pen, or marker. Start from the center of the tuft and move approximately on a straight line and count outward toward the edge (or vice versa). This minimizes the risk of counting the same fiber more than once. Carefully inspect the tuft for fibers that have been forgotten or counted twice. Some fibers are broken. Carefully check that the two halves of the broken fiber are not counted as two separate fibers. Adjust the grand total accordingly. The fibers are counted again on a second line in a different direction from the first count. The maximum number of fibers counted is the “total number of fibers per tuft” in that tuft. Select images of the same tuft from different angles. Obtained by counting fibers in the tuft from a second viewing angle, counting from one side to the other (eg from left to right) or counting along the top of the tuft. Verify the accuracy of the grand total. If the fibers are unclear from one viewing angle and the sum obtained from different angles gives a larger number, the larger number is selected as the number of fibers in the tuft. Only individual fibers are counted, not entangled or melted areas, which may occur as a result of processing including any processing such as hot melting or low temperature welding at the top of tufts or loops Make sure.

(Fiber end counting)
Count all fiber ends visible in the tuft. A pencil, pen, or marker is used to identify each counted end. This minimizes the risk of counting the same end more than once. Examine the tuft image carefully and look for the edge that you forgot to count. Adjust the grand total accordingly. The result obtained is “number of fiber ends per tuft”. Note that some fibers may be drawn from the web surface and exposed only at one end, in which case the “number of fiber ends per tuft” may be an odd value rather than an even value. To do. It is reported as a counted value regardless of whether the value obtained is odd or even.
At least one more tuft, the process of counting “total number of fibers per tuft” and “number of fiber ends per tuft” is repeated. Report the averaged result.

(Number of fibers per tuft that is not broken)
According to Formula 1, “the number of fibers per tuft that is not broken (N)” is calculated.
(1) N = total number of fibers per tuft− (number of fiber ends per tuft) / 2
According to Equation 2, the “number of fibers per unbroken tuft” is expressed as a percentage.
(2) N /% = 100 × N / total number of fibers per tuft

(Fiber diameter)
Visually inspect the micrographs of the tufts at a magnification suitable for measuring the width of individual fibers. Examine tufts for fiber diameter uniformity. If the fiber diameter appears to be fairly consistent, select one fiber that appears to be representative and set the caliper spacing to the width of the fiber. Compare the caliper spacing with an additional 5-10 fibers in the tuft to confirm that the selected fibers were representative. If most fibers appear larger (or smaller) than the caliper setting, adjust the gap and repeat the comparison. The actual diameter is calculated as the 6-11 average caliper reading taken, the result is corrected using the scale bar, and the actual diameter is reported as an average value as a result. The result is the “average diameter of the fibers in the tuft”. Similarly, focus on the bulk web and visually inspect for uniformity. The same procedure as for tuft fibers is used to determine representative bulk fiber diameters. Average the results and use the scale bar to correct the results to actual dimensions. The result is the “average diameter of the fibers outside the tuft”. The diameter ratio can be easily determined as a measure of the extent of fiber withdrawal.

(Taft height, maximum tuft width, and minimum tuft width)
Select the same photomicrograph as the first used to count the fibers looking through the open portion of the tuft (which may be a loop). In the micrograph shown in FIG. 22, the height of the tuft is H, the maximum width of the tuft is W, and the minimum width of the tuft is B. Visually examine the micrograph for the uniformity of the measured tuft dimensions. To measure the maximum tuft width, set the caliper spacing to the width of the tuft at the widest point. Most tufts have some random loose fibers that protrude dramatically from the bulk of the tuft. These fibers are not included in the caliper gap. Compare the caliper spacing to several more (5-10) tufts. Average the results and use the scale bar to adjust the results to the actual dimensions. Follow this same procedure for the height of the tuft and the minimum width of the tuft.

The personal care article of the present invention is at least associated with a fibrous nonwoven web useful for cleansing and / or treating similar keratinous surfaces of skin, hair, and body in addition to the fibrous web of the present invention. One cleansing and / or treatment composition is required. We expect a combined action of a tufted web and a treatment / cleansing ingredient (ie, a composition as part of another composition) associated with the web of the invention in personal care products. I found that it would bring a level of profit. Without being limited by theory, a large number of fibers oriented perpendicular to the plane of the web can advantageously provide a soft or uneven feel when combined with the treatment composition of the present invention. In addition to providing a surface, it is believed to provide unique cleansing, exfoliating, treatment, and / or foam benefits.

For example, only about 0.25 g to about 10 g (0.25 to 10.0 gsm) of dry surfactant component per square meter of web surface area can provide a foam benefit useful for facial cleansing. Since the tufted web is a low density property, the web is also useful for wiping the designated surface or for releasing the treatment composition to the designated surface. It is possible to hold a liquid treatment component at least about 10 times the weight of the web. Other uses of the article of the present invention will become apparent from the examples disclosed herein.

In some cases, the personal care article of the present invention may appear to contain no deformation. For example, a stack of 30 personal care products of the present invention that are folded and interleaved, each product comprising a 500 wt% viscous, opaque therapeutic semi-solid emulsion of the substrate. May not immediately reveal the tufts and loops contained therein. Hiding the presence of the deformation does not impair any of the benefits gained thereby, and the presence of the deformation, i.e. tufts and / or loops, is first demonstrated by removing the personal care composition from the web of the present invention. be able to.

(Constant foam volume test)
The article of the present invention can provide a steady foam profile as described below. Body cleansing compositions have a high total steady foam volume, while non-foaming articles have a low steady instantaneous foam volume. The personal care product can be a cleansing product or a non-cleansing product, and can be a foaming product or a non-foaming product with a different foam profile as described below. The steady foam volume test gives an indication of the foam profile of the article in a fresh water supply, i.e. naturally present when bathing or taking a shower.

  The foam profile described herein is a combination of the steady instantaneous foam volume and the steady total foam volume, both of which are determined according to the following steady foam volume test. Select eight 1,000 mL graduated cylinders (eg, Pyrex No. 2982) that are marked at 10 mL intervals and have a height of 368.3 mm (14.5 inches) from the inside of the base to the 1,000 mL mark To do. Add 100 g of distilled water (± 0.3 g at 23 ° C.) to each graduated cylinder. Numbering the cylinders in order from the first cylinder (cylinder 1) to the last cylinder (cylinder 8), with the cylinder standing upright, the cylinder is clamped with a rotating shaft that crosses the center of the graduated cylinder with an axis parallel to the ground. Clamp these cylinders in the apparatus. Add stopcocks to cylinders 2-8.

  The article is prepared by cutting into four equal width strips with the longest dimension. If the contents are incorporated into the article and they spill out when the article is cut into strips, the article is folded into four equal strips instead. If it is not possible to fold it into the graduated cylinder due to the size of the product, cut the product into strips that can be inserted and receive any spilled contents during this procedure, as described below. Add separately to the first graduated cylinder. The strips are stacked and one end is sandwiched between simple binder clips selected to be thin enough to fit inside the graduated cylinder neck. A thin polymer line, such as a thin fishing line, is tied to the clip so that the strip hangs vertically from the clip and line when the line is held high. With the top of the strip stack hanging down to the same height as the 1,000 ml mark on the side of the first graduated cylinder (cylinder 1), the strip is placed in cylinder 1 so that the strip hangs vertically inside the graduated cylinder. Put in.

  Next, a stopcock is inserted into the neck of the cylinder 1 to secure the product strip to the graduated cylinder. If necessary, the thread suspended above can be taped to the outside of the cylinder 1 before inserting the stopcock. In order to prevent leakage, a water-resistant seal can be provided using Teflon (registered trademark) tape. The cylinder is rotated 50 times by a rotating device at a stable speed of 50 rotations in 88 seconds to generate foam composed of foam cells and stopped in a vertical position to complete the first rotation sequence.

  A timer is set and the bubbles thus generated are drained for 30 seconds. After such 30 seconds of draining, by recording the height of the foam from the base in ml in cylinder 1, the first foam volume expressed as the amount of foam in cylinder 1 is rounded off to the nearest 10 ml. Measure (the height includes water floating above the bottom and drained to the bottom). If the top surface of the foam is not uniform, the lowest height at which half of the first graduated cylinder can be seen is the foam volume (ml) of cylinder 1. If the foam is rough and only a single or only a few foam cells are spread across the cylinder, the height required for at least 5 foam cells to fill the diameter will be the amount of foam in cylinder 1 (again the base From mL). Foam cells having a diameter greater than 25.4 mm (1 inch) are represented as hollow air rather than foam when they occur on the top surface of the foam. Also, for bubbles that collect at the top of the graduated cylinder but do not move to the bottom of the graduated cylinder, measure the thickness of the layer using a ruler, convert it to volume ml, and add the mL of foam collected there. By adding to mL of foam measured upward from the base, it is incorporated into the top foam measurement as being in its own continuous layer. A semi-circular flexible plow attached to a rod if a significant amount of foam (eg, a volume of about 60 ml or more) hangs down the side of the graduated cylinder, making the total foam volume measurement inaccurate or difficult, For example, using a 50.8 mm (2 inch) diameter stopper cut from the sponge, cut in half and secured to a long threaded rod (during 30 seconds of draining), the top and The side foam is moved to the bottom of the graduated cylinder and combined with the other foam before measuring the volume. The maximum foam volume that can occur is 1,000 mL (even if the total height of the foam exceeds the 1,000 mL mark on the graduated cylinder). The minimum foam volume that can occur is 100 ml (even if no foam is present and the height of the water in the graduated cylinder is indicated at the top of the foam and measured as the amount of foam in cylinder 1).

  After recording the amount of foam in cylinder 1, hold the thread to remove the stopcock, remove the strip from the first graduated cylinder, and then reattach the graduated cylinder to the cock. Hold the strip of product with the thread alone and allow the strip to lightly touch the absorbent paper towel stack for a few seconds to remove water drops from the bottom of the strip. Then, in the same manner as described above, the strip of goods is fixed inside the second graduated cylinder, numbered as cylinder 2 above, and its stopcock is added, and the second rotation sequence is performed. Upon completion, measure the foam volume in the second cylinder in the same manner as described for the first graduated cylinder and record as the amount of foam in cylinder 2. This sequence is continued a total of 8 times and the foam volume in each graduated cylinder is recorded as the foam volume for that cylinder. That is, the foam volumes in cylinder 1, cylinder 2, cylinder 3, cylinder 4, cylinder 5, cylinder 6, cylinder 7 and cylinder 8 are the foam volume of cylinder 1, the foam volume of cylinder 2, and the foam volume of cylinder 3, respectively. , The amount of foam in cylinder 4, the amount of foam in cylinder 5, the amount of foam in cylinder 6, the amount of foam in cylinder 7, and the amount of foam in cylinder 8. The steady instantaneous bubble volume is obtained by adding the amount of bubbles in cylinder 1 and the amount of bubbles in cylinder 2. The steady total foam volume is obtained by adding the foams obtained in all 8 graduated cylinders.

(Mechanical foam volume test)
The personal care product of the present invention provides the mechanical foam volume described below. The personal care product can be a cleansing product or a non-cleansing product, and can be a foaming product or a non-foaming product with different mechanical foam volumes as described below. The mechanical foam volume test is used in situations where the supply of water is limited, i.e. when washing in the wash basin, e.g. when washing the face in the wash basin, especially in foamy cloths, cloth-like products or fibrous nonwoven webs. Is used to give an indication of the mechanical foam of the article, as is naturally present when removing makeup with a wash basin.

  Select a 1,000 mL graduated cylinder (eg, Pyrex 2982) that is marked at 10 mL intervals and has a height of 368.3 mm (14.5 inches) from the inside of the base to the 1,000 mL mark. Add 25 g of distilled water (± 0.1 g at 23 ° C.) to the graduated cylinder.

  The article is prepared by cutting into four equal width strips by cutting longitudinally with the longest dimension. The strips are stacked and one end is pinched by a binder clip (designated as the top clip) selected as thin enough to fit inside the neck of the graduated cylinder. If the contents are incorporated into the article and they spill out when the article is cut into strips, the article is folded into four equal strips instead. If it is not possible to fold it into the graduated cylinder due to the size of the product, cut the product into strips that can be inserted and receive any spilled contents during this procedure, as described below. Add separately to the first graduated cylinder.

  A binder clip is attached to the bottom of each strip, facing away from the top clip. At the center of each strip, a binder clip is attached at an angle of 90 degrees from the direction of the top and bottom clips. Each clip weighs an average of 2.7 g. The clip causes the mechanical action that allows the strip to alternately shrink to full length and expand to full length as the cylinder rotates, generating foam in the presence of the foaming surfactant component. So as to give weight. A thin polymer line, such as a thin fishing line, is tied to the upper clip so that the strip hangs vertically from the upper clip and line when the line is held high.

  The strip is placed in the cylinder so that the strip hangs vertically inside the graduated cylinder, with the top of the strip stack hanging down to the same height as the 1,000 ml mark on the side of the cylinder. Insert a stopcock in the neck and secure the strip of equipment against the graduated cylinder. The cylinder is rotated 25 times at a steady speed of 25 rotations in 44 seconds to generate a mechanical foam composed of foam cells and stopped in a vertical position. Observing the strip during rotation causes each rotation to repeat a cycle in which the strip causes maximum compression and then reverses to cause maximum expansion in the original vertical position. The degree of compression is based on the compliance of the strip in the wet state and therefore varies. Due to interference factors such as (1) rotational speed of the cylinder that is too fast, (2) interference from the generated foam, (3) sticking of the strip to the cylinder wall, or (4) a combination of these factors, If compression of a compliant strip (i.e., relatively easy to compress in the length direction) is not observed during the reversal phase of rotation, the strip may compress at each inversion and expand in a vertical position. Reduce the rotational speed of the device until it is observed. It is important to complete 25 complete compression-expansion cycles of the strip to the extent that the strip undergoes compression and expansion based on the compliance of the strip. If the strip does not undergo compression and expansion, the rotational speed is reduced to about 15 revolutions per minute (rpm) to achieve the intended compression-expansion of the strip. Nevertheless, if the strip does not compress and / or expand due to the interference factors described above, during each rotation, the cylinder is momentarily held in place in each vertical position and shaken by hand to the strip. Causes compression and expansion.

  The measurement is then continued for the second 25 revolutions by restarting the rotator. The rotating device should be restarted within 5 seconds of stopping. The rotation device is restarted again within 5 seconds after stopping, and the third 25 rotations are completed. Remove the stopcock and use the attached thread to lower the article to the bottom with bubbles gathered on it. Using the same plow as described in the steady foam volume test, the foam remaining on the side and top of the graduated cylinder is moved to the bottom of the graduated cylinder. Use a plow to ensure that the top surface of the foam is uniform. If the top of the foam surface extends beyond the crushed article, before reading the foam volume, again using a plow, use a large (> 25.4 mm (1 inch) within the crushed fibrous nonwoven web when lowered. )) Ensure that the air cavity is filled with foam. If the top of the foam surface does not extend beyond the article, the foam is moved by the plow to the lowest possible position in the cylinder without breaking or compressing the foam.

  If the foam height exceeds the top height of the fibrous nonwoven web, the mechanical foam volume is the height of the foam including the underlying fibrous nonwoven web. The foam height is measured within 15 seconds after stopping. If the height is below the top height of the fibrous nonwoven web, the mechanical foam volume is the height of the highest part of the foam surface that extends into the graduated cylinder. If the article expands during the test so that the sponge expands when first wetted, the plow is used to push the foam off the surface of the expanded fibrous nonwoven web, which is lowered to the bottom of the cylinder. Not included in the height of the foam. If the article inflates during the test so that the balloon inflates with air, prepare the article by scratching and / or drilling a new article of the same type so that it does not inflate, repeat the test, and mechanical The foam volume is the height of the foam on a scratched or perforated article. The maximum foam volume that can occur is 1,000 mL (even if the total height of the foam exceeds the 1,000 mL mark on the graduated cylinder). The minimum foam volume that can occur is 0 ml (the height of the water, which can be absorbed by the article). If no foam is visible inside the graduated cylinder, there is no need to lower the article and measure the height, and the mechanical foam volume is expressed as the height of the water at the bottom of the graduated cylinder.

(Moisture retention measurement method)
As mentioned above, the article of the present invention can be “substantially dry”. As used herein, “substantially dry” means that the article of the invention is less than about 0.95 g, preferably less than about 0.75 g, more preferably less than about 0.5 g, and even more preferably about It is meant to exhibit a moisture retention of less than 0.25 g, more preferably less than about 0.15 g, and most preferably less than about 0.1 g. Moisture retention is a measure of dry feel as opposed to the feel of a “wet” wipe as perceived by the user when touching the article of the present invention.

  The following equipment and materials are required to measure the moisture retention of products based on this product and other disposable fibrous nonwoven webs.

次に、２枚のペーパータオルの重量を別々に測定し、各重量を記録する。１枚のペーパータオルを平らな表面（例えば、実験室の作業台）上に置く。そのペーパータオルの上に試料用品を置く。試料用品の上にもう一枚のペーパータオルを置く。次に、間に挟まれた試料用品上に、レキサンを置き、次いで２０００ｇのおもりを置く。１分待つ。１分後、おもり（１つ又は複数）及びレキサンを取り除く。上部及び底部のペーパータオルの重量を測定し、重量を記録する。

Next, weigh the two paper towels separately and record each weight. A piece of paper towel is placed on a flat surface (eg, a laboratory bench). Place the sample article on the paper towel. Place another paper towel on top of the sample article. The lexan is then placed on the sample article sandwiched between, and then a 2000 g weight is placed. Wait 1 minute. After 1 minute, the weight (s) and lexan are removed. Weigh the top and bottom paper towels and record the weight.

  For both top and bottom paper towels, the moisture retention is calculated by subtracting the initial paper towel weight from the final weight (after 1 minute). Add the weight differences obtained for the top and bottom paper towels. Assuming a large number of articles to be tested, the total weight difference is averaged to obtain the moisture retention.

  As mentioned above, the articles of the present invention can be “substantially dry”, “wet”, or “wet” prior to use. The article can give a dry feel when touched and still has a high moisture content. Moisture retention is a measure of dry feel, as opposed to the feel of a “wet” article as perceived by the user when touching the article of the present invention. Thus, an article of the invention that feels dry when touched can provide a dry feel, regardless of the amount of fluid contained therein. An article of the invention having a dry feel is less than about 0.95 g, preferably less than about 0.75 g, more preferably less than about 0.5 g, even more preferably less than about 0.25 g, and even more preferably about 0.15 g. Less than, most preferably less than about 0.1 g water retention.

  As mentioned above, the articles of the present invention can be “wet” prior to use. The article can give a wet feel when touched and has a high moisture content. The weight percent of fluid in the “wet” article is based on the dry weight of the web. The weight is expressed as the weight of the total composition. Thus, “wet” articles of the present invention generally have greater than about 40 wt% fluid, preferably 40 wt% to about 95 wt% fluid, more preferably about 50 wt% to about 80 wt% fluid. including.

(Production method)
The article of the present invention can be used to add and / or impregnate the web with cleansing and / or treatment compositions separately or simultaneously before or after the web is subjected to selective mechanical deformation. Can be manufactured. “Separately” means that the cleansing composition and the treatment composition can be added sequentially in any order without first being combined. “Simultaneously” means that the cleansing composition and the treatment composition can be added initially or in combination.

  The cleansing and / or treatment composition can be incorporated on or impregnated into the fibrous nonwoven web using any means known to those skilled in the art. These components can be applied using various spraying, infiltration, coating, or dipping methods. Excess surfactant and / or conditioning components can be removed (eg, by a nipping method). The resulting article can be left wet or can be further processed and wetted or dried using conventional methods known in the art.

(Usage of equipment)
The present invention also relates to a method of cleansing and / or treating skin, hair, or other keratinous tissue of the body with the personal care article of the present invention that is soft due to the structure of the fibrous nonwoven web. These methods include the steps of wetting a disposable personal care article comprising a fibrous nonwoven web with a fluid and wiping the area to be cleansed and / or treated with a cleansing and / or treatment composition with the article. The article of the present invention can be wetted with fluid prior to use, can already contain fluid prior to use, or can be one that does not require fluid to use the article. The substantially dry article is wetted by dipping in the fluid or by placing it under a fluid flow. Foam is generated from the article by mechanically stirring and / or deforming the article before or during contact with the skin, hair, or other keratin-containing surface.

  The resulting foam is useful for cleansing and / or treating skin, hair, or other keratin-containing surfaces. During the cleansing / treatment process and subsequent water rinses, the treatment and active ingredients come into contact with the skin, hair, or other keratin containing surface. The adhesion of the treatment composition and active ingredient is improved by physical contact between the fibrous nonwoven web and the skin, hair, or other keratin-containing tissue of the body.

  Without being limited by theory, it is believed that the fibrous nonwoven web contributes significantly to foam generation and adhesion of the treatment composition and any other active ingredients. This foam and adhesion is believed to be the result of the surface action of the fibrous nonwoven web. As a result, a very small amount of surfactant, which is less irritating, can be used. The reduction in the amount of surfactant required is believed to be related to the reduction of the skin or hair drying effect by the surfactant. In addition, reducing the amount of surfactant reduces the disturbing effects that the surfactant exhibits on the deposition of the treatment composition (eg, disturbing effects due to emulsification or direct removal by the surfactant). Further, without being limited by theory, the fibrous nonwoven web is also believed to improve the adhesion of the treatment composition and the active ingredient. In addition, the treatment composition and the active ingredient are incorporated onto or impregnated into the fibrous nonwoven web so that wet, moist or wet articles are applied to the skin, hair, or other keratin-containing surface. Surface treatment causes the treatment composition and the active ingredient to move directly into the skin.

  The following examples further describe and demonstrate embodiments within the scope of the present invention. The examples are given for illustrative purposes only, and many variations thereof are possible without departing from the spirit and scope of the invention, and should not be construed as limiting the invention. Absent. Unless otherwise specified, all exemplified amounts are total cleansing, concentrations based on the weight of the treatment composition.
