Description

Wiping Member and Cleaning Products {WIPING MEMBER AND WASHING ARTICLE}

The present invention relates to a wiping member. In particular, the present invention relates to a wiping member for use in cleaning or polishing a surface.

Products comprising a wiping member made by knitting or weaving a flat yarn made of plastic film or a metal yarn made by metalizing a plastic film are well known products. The product may be molded into a sack to put a urethane sponge or the like into the sack. The cleaning product has a knitted fabric with many bends of the film on its surface, and if the bends face dirt at a particular angle, the bulk of the cleaning product can be scraped or rubbed off by the shape and stiffness of the film. Excellent performance in removing dirt.

However, the wiping article does not have a sufficient contact area with the surface of the object to be cleaned and, therefore, is not very effective in removing dirt that is thinly spread on the surface of the object to be cleaned, such as an oil film. On the other hand, many wiping articles are also known which use ultrafine fibers or acrylic fibers having a release cross section for the purpose of removing oil films and the like without using detergents. When the fiber alone is used, it shows a high effect on dirt such as oil film, but there is a problem in that it is impossible to efficiently scrub and remove bulky solid dirt such as burned or soapy residue.

Japanese Utility Model Publication No. 3037459 is a wiping member comprising a combination of a yarn such as acrylic yarn and a plastic film, which is manufactured by knitting an acrylic worsted yarn in which a plain yarn made of metallized plastic film is spirally wound around the yarn. Disclosed is a scrubbing brush cloth. However, this structure cannot sufficiently exert the effect of the film scrubbing the dirt because the film is wound parallel to the acrylic worsted yarns and the film does not face dirt at an effective angle.

As a similar example, a wiping member including a bag made of a knitted fabric in which a polypropylene worsted yarn and an acrylic worsted yarn are alternately knitted together with a plain yarn made of a polyester film to form a stripe shape and a sponge shim placed in the bag are commercially available. . However, in the knitted fabric of such a structure, the polyester film is linearly and unevenly distributed. Therefore, it is inconvenient due to the anisotropic ability to remove dirt, and the efficiency of scrubbing the dirt is poor.

[Overview of invention]

The present invention provides a wiping member and a cleaning article capable of removing even dirt that is thinly spread on the surface to be cleaned while maintaining the ability to remove bulky solid dirt. In one embodiment, the present invention provides a wiping member comprising plain yarn and fiber yarn. The plain yarn and the fiber yarn are knitted together to form separate loops of the plain yarn and the fiber yarn.

In another embodiment, the present invention is a cleaning article comprising a wiping member comprising a plain yarn and a fiber yarn, wherein the plain yarn and the fiber yarn is knitted together to alternately form separate loops of the plain yarn and the fiber yarn Provide cleaning products. In addition, an absorbent cleaning material is adjacent to the wiping member.

While the foregoing figures and figures illustrate embodiments of the present invention, other embodiments are intended as discussed below. In all cases, the present disclosure is presented by way of representing the invention and is not intended to limit the invention. Those skilled in the art should understand that numerous other modifications and embodiments can be devised that fall within the scope and spirit of the invention. The picture does not have to be drawn at a constant rate.

Knitwear is inherently a fabric made by using a series of yarns to form a plane by engaging the loops with each other in the longitudinal or transverse directions. The structure of a knit consists of a series of loops. Thus, when the knitted fabric consists of a flexible anisotropic yarn such as plain yarn made of plastic film, the bends of the loops will be arranged regularly, protruding from the surface of the cloth at a substantially fixed angle (orientation).

In the production of such knitted fabrics, when the plain yarn made of plastic film is partially replaced by a fibrous yarn such as a wet spun yarn made of acrylic fiber and knitted uniformly, the plastic film loop and the acrylic fiber loop are regularly, for example alternately, It is arranged every one stitch or every two stitches or more. This will allow the plastic film loops to be uniformly and regularly arranged throughout the surface of the resulting knitted fabric, and the loops of acrylic fiber will be arranged with the same regularity between the plastic film loops.

When the plain yarn made of plastic film is looped as described above, the tip of the bent portion protrudes from the surface of the cloth. Accordingly, a knitted fabric prepared by uniformly knitting a plain yarn made of plastic film together with a spun yarn made of partially wet spun acrylic fiber has a plurality of bent portions of the plastic film arranged uniformly and regularly throughout the surface of the cloth. will be. The tip of the bend will project from the surface of the cloth at a nearly fixed angle.

By "evenly knit" is meant that two or more yarns are used equally to produce an overall uniform knit. Preference is given to using the yarn in about the same amount (length). As long as the wiping member of the present invention has the bent portion of the plain yarn made of plastic film in the above-described arrangement, the wiping member further includes yarn or fiber uniformly knitted together with the plain yarn of the plastic film and the wet spun yarn made of acrylic fiber. can do.

However, for example, knitted fabrics prepared by knitting yarns of different species, which are not uniform throughout the fabric, do not correspond to the uniform knitted fabric as used herein.

The manner of knitting the knitted fabric is not particularly limited, provided that it is a knitting manner generally used for wiping members for use in washing or polishing dishes, pans and the like in the kitchen or the like. Preference is given to a knitting manner in which the opening is formed between the curved surface of the plain yarn made of plastic film and the knitted surface. The presence of the opening facilitates the entry of the plain between the object to be cleaned and the dirt attached thereto, so that both are easily separated. It is also possible to capture large amounts of separated dirt in the openings. Thus, such knitted fabric can maintain good scrubbing performance.

Typically, the manner in which the knit is knitted is not particularly limited as long as the knit consists of a series of loops. However, knits with large gauges cannot have openings of sufficient size in their loop portions. As the stitch density increases, the direction of projection of the film becomes close to parallel to the knit and the surface to be cleaned, and it becomes more difficult to obtain a wiping effect. On the other hand, when a low gauge knitted fabric is used in the form of a bag including a foam member therein, foreign matter tends to enter it, causing problems in using it and also causing hygiene problems. . Depending on the thickness of the yarns to be used, for example, when using 30 to 60 denier double acrylic yarns, the number of stitches per square with a side of 10 cm is typically about 20 stitches x 20 rows to 100 stitches x 70 rows More preferably about 30 stitches × 30 rows or 65 stitches × 50 rows.

In the case of plain yarn, plastic films having a thickness of 30 to 45 μm and a width of 0.7 to 0.85 mm are commonly used, since the stiffness of the film allows the scraping or rubbing of bulky solid dirt to be achieved. to be. As a material of a plastic film, polypropylene, polyester, polystyrene, etc. are used. It is also acceptable to use metal plain or other multilayer films (eg, films comprising plastic layers with metal layers sandwiched therebetween) made from metallization of plastic films to give designability and the like. .

When forming yarns, wet spun acrylic fibers are used because the acrylic fibers can easily remove oily dirt and the yarns have sufficient contact area with the surface to be cleaned. It is also acceptable to use microfibers having a release cross section by forming yarns.

The wiping member of the present invention can be used alone, as a wiper, or as a washing product for tableware such as a dish. When molded into a bag and then placed into a foam member such as a polyurethane sponge or the like, it can be used as a washing product for dishware such as a dish.

The wiping member is an acrylic that exerts cleaning power against dirt, such as an oil film that can only be scrubbed when the plain and cleaning products made of a plastic film capable of effectively scrubbing bulky dirt are in close contact with the surface to be cleaned. Since it is composed of a knitted or woven combination of yarns made of fibers such as, it has sufficient cleaning power against both bulky dirt and dirt such as oil membranes. Also, in knitted fabrics or woven fabrics, the plain of the rigid plastic film contacts the surface to be cleaned at a certain angle, so that the force applied during wiping will concentrate on a limited portion of the dirt and peel off the dirt from the surface to be cleaned. You can easily create a starting point for betting.

In addition, the present invention is described by the following examples. However, these examples should not be construed as limiting the invention in detail.

While specific embodiments of the invention have been presented and described herein, it is understood that these embodiments merely illustrate numerous possible specific combinations that can be devised by applying the principles of the invention. Those skilled in the art can devise a variety of different combinations in accordance with the principles of the invention without departing from the spirit and scope of the invention. Therefore, the scope of the present invention should not be limited to the structures described herein, but should be limited only to the structures described in the claims and the equivalents to the structures.

Example  One

Plain yarns made of PET film, 38 μm thick and slitting to a width of 0.7575 mm, were combined with 100 denier PET yarn for reinforcement. The group of yarns and 48 denier dimer acrylic yarns were uniformly knitted with a spherical knitting machine. Thus, a tubular knitted fabric was produced. The knitted fabric was inverted to expose the back surface to form a wiping member.

1 is an enlarged photograph showing the structure of the front surface (ie, back surface of the knitted fabric) of the prepared wiping member. Loops of PET film plain and acrylic yarns are alternately placed several millimeters apart. When the fabric thus prepared is placed on the surface to be cleaned in the same manner as in actual cleaning, the film surface contacts the surface to be cleaned at an angle of about 45 degrees at the loop portion.

The wiping member prepared above was evaluated along with the wiping member of Comparative Examples 1-3 for the ability to remove bulky dirt (soap residue) and the oil film. About a comparative example, it is shown with the evaluation result in Table 2.

In the evaluation, a wiping member containing water was applied alone to a stainless steel plate to which dirt was attached. Thereafter, the plate was wiped by moving it back and forth once with a thumb on the wiping member with a load of 0.7-0.8 kg. After wiping, the state of the stainless steel plate was visually observed and evaluated according to the criteria shown in Table 1.

Display O △ X  Removal of soapy debris  70% or more removal rate  30-70% removal rate  30% removal rate  Removal of oil film  No blur left -  Blurry areas remain

The dirt used in the evaluation was prepared in the following way:

Soap Scum:

A dispersion of fatty acid calcium powder in alcohol was evenly applied to a stainless steel plate (JIS G4305 (SUS 304) 2B). After evaporating the alcohol, the stainless steel plate was heated on a heated hotplate for about 2 minutes.

Oil membrane:

Using a paper towel, a 1: 1 mixture of salad oil and lard was applied thinly to a stainless steel plate (JIS, G, 4305 (SUS304) BA).

Example  2

Plain yarns made of a 38 μm thick aluminum metallized PET film slitting in a width of 0.7575 mm, and 300 denier spun yarns made of about 0.3 denier release cross-section filaments of polyester and nylon were uniformly knitted with a spherical knitting machine. Thus, a tubular knitted fabric was produced. The knitted fabric was inverted to expose the back surface to form a wiping member.

2 is an enlarged photograph showing the structure of the front surface (ie, the back surface of the knitted fabric) of the manufactured wiping member. The loop group of PET film plain yarns and the loop group of acrylic yarns are alternately positioned several millimeters apart. When the fabric thus prepared is placed on the surface to be cleaned in the same manner as in actual cleaning, the film surface contacts the surface to be cleaned at an angle of about 45 degrees at the loop portion.

The wiping member thus prepared was evaluated in the same manner as in Example 1 for the ability to remove bulky dirt (soap residue) and to remove the oil film. The evaluation results are shown in Table 2.

The evaluation results show that the soap residue and oil film were sufficiently removed in the examples. Meanwhile, in the comparative example, some scratches were generated on the surface of the soap residue layer, but the soap residue layer was not sufficiently removed. By using the wiping member of the present invention as mentioned above, it is possible to remove both bulky dirt and dirt firmly adhering to the surface to be cleaned, such as a mil film.

Example  3

The tubular knitted fabric prepared in Example 1 was molded into a bag and a polyurethane sponge block having a length of 140 mm, a width of 70 mm and a thickness of 20 mm was placed therein. Thus, a wash product was produced.

The wash was moistened with water and applied to a stainless steel plate with dirt attached in the same manner as in Example 1. By hand, the dirt was wiped by moving back and forth once in the direction along the long side of the wash. Thereafter, the state of the stainless steel plate was visually observed and evaluated according to the criteria shown in Table 1.

The dirty stainless steel plate was then replaced with another. On the surface of the substitute, a wash moistened with water was applied and the dirt was wiped by moving back and forth once by hand in the direction along the short side of the wash. Then, the state of the stainless steel plate was observed visually and evaluated in accordance with the criteria shown in Table 1. Table 3 shows the results of the evaluation.

Comparative example  4

Commercially available cleaning products ("Magical Net Triple" manufactured by Towa-JS Inc.) were prepared. 3 is a schematic view showing the appearance of the cleaning product. The wash product had the same external dimensions as the wash product of Example 3. In the knitted fabric, polypropylene worsted yarn knitted 1 and acrylic worsted yarn knitted 2 were alternately knitted together with aluminum metallized polyester plain yarn 3 to form streaks. The performance of the wash was evaluated in the same manner as in Example 3. Table 3 shows the results of the evaluation.

The wash product of Example 3 showed excellent removal performance for two types of dirt regardless of the wiping direction. On the other hand, in the use of the cleaning product of Comparative Example 4, when the dirt was wiped in the direction along the short side of the cleaning product, the dirt remained streaked, and thus was not sufficiently wiped off. When the dirt was wiped in the direction along the long side of the cleaning product, the amount of film effective for scrubbing was insufficient, and thus the dirt was not sufficiently wiped off.

In short, the cleaning products of the present invention are uniformly distributed over the entire wiping surface because the acrylic yarns effective for wiping the film portion and the oil film which will effect scrubbing are uniformly distributed over two kinds of soils regardless of the wiping direction. Excellent removal performance. In other words, the high scrubbing force probably comes from the structure in which the loop portion of the film appears in succession, which in turn scrubs the dirt.
