Description

CELLULOSE FIBER BLENDED FABRIC}

The present invention relates to a special fabric in which fibers are mixed in which the dimensions change upon absorption. More specifically, the cellulose fibers which have a dimensional change (absorption magnetic extension or absorption self-contraction) at the time of absorption are mixed to provide a comfortable fabric at the time of wearing sweating.

In conventional clothes, when the sweat occurs by sports or the like, the fabric absorbs the sweat and the skin and the fabric adhere to each other, and there is a so-called stickiness or stuffiness. Various fabrics have been developed to prevent this, but only the fabric structure has a limitation in the comfort when absorbing sweat. In order to relieve this stickiness and stuffiness, the fabric and the garment which use the fiber which extends when sweat is absorbed (at the time of absorption) are proposed. For example, a garment that improves breathability at the time of absorption by using a fiber that is self-extending at the time of absorption (see Patent Documents 1, 2 and 3), and expresses irregularities when absorbing sweat (see Patent Documents 4 and 5). ), Clothing and the like have been proposed.

Certainly, the clothes proposed in these patent documents are more comfortable at sweating than clothes which do not use the absorbent magnetic elongation yarn. However, the fibers used in these garments are hardly hygroscopic or absorbent, and do not absorb moisture due to involuntary evaporation of the body. For this reason, there is an unpleasant feeling even when not wearing a sweat, and since sweat absorption is not possible even when sweating, it becomes a garment which remains sticky or stuffy. It is known that hygroscopicity is good when normal cellulose fiber is used, and it is comfortable at the time of wearing. However, when sweating due to exercise or the like feels sticky or stuffy, fabrics that have advanced functions such as improving breathability at the time of absorption are desired. As described above, fibers which provide comfort both at the time of wearing and at the time of sweating cannot be found at present.

EMBODIMENT OF THE INVENTION Hereinafter, this invention is demonstrated in detail.

Cellulose fibers in the present invention are cupra, rayon, purified cellulose fiber, bamboo fiber, cotton, and the like, and regenerated cellulose such as cupra and rayon is preferably used. Moreover, in order to make a woven fabric, these long fiber and short fiber (spun yarn) are used. In the long fiber, 11dt (decitex: the same symbol is used below) to 400dt, and in the single fiber, 160S (cotton number: the same symbol below) to 10S are used. In addition, it is possible to form a twisted pair of triangular yarns and trifiber yarns twisted with long fibers and short fibers, or long fibers and short fibers, and to use them as the thicknesses of the respective tissues. In the long fiber, about 40dt to 170dt, and in the short fiber, about 30S to 120S are easy to handle, and it is preferable.

The fabric of the present invention is a fabric in which cellulose fibers having a dimensional change rate at absorption of 2% or more are mixed. There are two kinds of cellulose fibers having a dimensional change rate at the time of absorption of 2% or more, absorbent stretchable cellulose fibers and absorbent self-shrinkable cellulose fibers. MEANS TO SOLVE THE PROBLEM This inventor discovered the method of obtaining an absorbent self-extension cellulose fiber and an absorbent self-shrinkable cellulose fiber preferably, investigated the fabric structure for making the most of each performance, and reached | attained this invention.

Absorption self-extension cellulose fiber is a cellulose fiber whose absorption elongation becomes +2% or more, Preferably an absorption elongation rate is +3% or more.

An absorbent self-shrinkable cellulose fiber refers to the cellulose fiber whose absorption elongation becomes -2% or less.

On the other hand, in the present invention, fibers having a dimensional change rate at absorption of less than 2% are referred to as ordinary fibers.

As normal fiber, polyester fiber, such as polyester and polytrimethylene terephthalate, polyamide fiber, polyurethane fiber, cellulose fiber, acetate, which are not provided with the absorption dimension change performance by alkali treatment or twisted yarn mentioned later, Long fibers or short fibers of arbitrary fibers, such as wool, are mentioned. These cross-sectional shapes may be arbitrary, and may be mold release yarns, such as a round cross section and a W-shaped cross section.

In the present invention, the rate of dimensional change at the time of absorption is obtained by the following method. In an environment of 20 ° C., 65% RH, the fiber length (A) is measured under a load of 0.05 g / dt (decex), and the fiber is then soaked in water for 30 seconds. Subsequently, the fiber is taken out of water, and the fiber length B after 30 seconds is measured under a load of 0.05 g / dt. Absorption elongation is calculated | required by following formula (1). And according to following formula (2), let the absolute value of the obtained absorption elongation rate be a dimension change rate at the time of absorption.

On the other hand, measurement of the dimensional change rate at the time of absorbing the fibers in the fabric is carried out under the same conditions by extracting the fibers from the fabric. At this time, the length of the fiber to be measured is 30 cm, but if the fiber of 30 cm cannot be extracted from the fabric, the length of the fiber is measured. In this case, in order to obtain an accurate value, the number of measurement samples is appropriately increased and measured. Also, in the case of a composite yarn or a mixed yarn or a twisted yarn in which a plurality of fibers having different dimensional change rates when absorbed are mixed by fluid interlacing processing or twisting yarn, such as interlacing, the fibers are extracted from the fabric, and the composite yarn, mixed yarn The rate of dimensional change in absorption under the same conditions in the state of twisted yarn is measured.

Absorption Elongation (%) = ((B-A) / A) × 100 (1)

% Absorption Rate of Absorption Dimension = Absolute Absorption Rate (2)

Hereinafter, the structure of the absorption magnetoextension cellulose fiber and the fabric of this invention using the said fiber is demonstrated.

The absorption elongation cellulose fiber of this invention is +2% or more in absorption elongation, Preferably it is +3% or more. What is necessary is just to process a normal cellulose fiber in aqueous alkali solution, in order to make a cellulose fiber into an absorption magnetic extension thread. Alkali treatment of cellulose fibers has conventionally been known, for example, the processing of a silk is the most common treatment method. However, in the present invention, by breaking the conventional common sense and performing a severe alkali treatment, it succeeded in the production of cellulose fibers that are elongated by 2% or more, preferably 3% or more at the time of absorption.

Specifically, it is obtained by immersing a cellulose fiber in 20 degreeC or more and 5 minutes or more in aqueous solution containing 20 g / L or more of sodium hydroxide, for example. Control of absorption elongation is possible by control of these conditions. For example, as the treatment conditions such as alkali concentration, temperature, and time are gentler, the absorption elongation rate becomes smaller, but it is difficult to obtain a cellulose fiber having an absorption elongation rate of more than one limit, for example, 20% even if the treatment conditions are severe. . As an alkali treating agent, a well-known thing can be used, For example, alkali metal hydroxides, such as sodium hydroxide and potassium hydroxide, can be used.

As alkali concentration, 20-200 g / L aqueous solution equivalence is more preferable. As for processing temperature and time, it is more preferable to process 5-120 minutes at 20-110 degreeC, respectively. This treatment temperature is the highest temperature at the time of treatment, and the treatment time is the total time including the time from the time of alkali addition, exceeding 20 ° C, until reaching the highest temperature and cooling from the highest temperature to less than 20 ° C after treatment. These time should just be 5 minutes or more. Moreover, after discharging cooling water, it is preferable to wash with water and neutralize it quickly. The method of alkali treatment is arbitrary, such as the method of performing in a state of a cellulose fiber, and carrying out a dyeing process after a knitting, or the process of alkali-processing after fabric manufacture using the cellulose fiber before alkali processing, and continuing dyeing processing. The method of carrying out after fabric manufacture is easy.

In addition, even when the immersion treatment is performed in a strong acid solution such as acetic acid or malic acid, the absorbent self-extension cellulose fibers can be obtained, but the effect of the absorbent self-extension cellulose fibers is slightly smaller than the alkali treatment under the above conditions.

In the cellulose fiber mixed fabric of the present invention, the use of cellulose fibers which are particularly excellent in hygroscopicity and moisture resistance greatly contributes to the comfort of wearing, and has a great difference in wearing comfort from the fabrics proposed in Patent Documents 1 to 5 proposed so far. To produce. That is, by using the absorbent self-extending cellulose fiber, which is a major feature of the cellulose fiber blended fabric of the present invention, the cellulose fiber is elongated at the time of absorption (when the sweat is absorbed in the state of wearing clothing), thereby improving moisture resistance. The effect of using a cellulose fiber can be heightened further.

In the method of mixing the absorbent self-extension cellulose fibers and the normal fibers, the method of alternating or knitting the fibers by the method of pulling the normal fibers and the absorbent self-extension cellulose fibers on a knitting machine or a loom or the like, or the absorbing self-extension cellulose fibers And ordinary fibers can be mixed by producing a woven fabric using a composite yarn such as twist, composite twist, interlacing and the like. On the other hand, in the case of a composite yarn, elongation of the composite yarn may not be remarkably obtained at the time of absorption depending on the composite method. In order to avoid this, the difference in yarn length from the normal fiber than the absorbent stretch cellulose fiber is designed so that the feeding amount (feed rate) is shortened to 0 to 9% in the absorbent stretch cellulose fiber in the state of finishing the fabric. If the yarn length difference is greater than 9%, the strength of the composite yarn is insufficient and sufficient fabric strength is not obtained. In addition, when the absorbing magnetic elongated cellulose fiber is longer, the fiber becomes thicker in appearance, so that the hygroscopicity and the moisture proofing property are lowered, and the object of the present invention may not be achieved.

In addition, the mixing rate of the cellulose fiber which absorbs self-extension in a composite yarn can be set arbitrarily, taking into account the effect acquired by a fabric design. It is preferable to make the cellulose fiber which absorbs magnetic extension into 20 to 80% of a mixing rate.

When fabrics such as woven fabrics and woven fabrics are produced using the absorbent self-extension cellulose fibers of the present invention, it is possible to impart various functions that are comfortable at the time of sweating by the knitting design and the fabric design. For example, a double circular knitting machine is used as an example of the structure in the case where the cellulose fiber of the part absorbed at the time of sweating stretches, and the fiber of the surface which comprises a fabric rises and forms a convex part on the fabric surface, If the structure in which one outer layer containing elongated cellulose fibers and the other outer layer containing ordinary fibers is partially separated from each other and the non-separated portions are regularly or irregularly repeated, the absorbing magnetic kidney cellulose fibers sweat When absorbed, it stretches and unevenness is expressed in a fabric, and it becomes a garment which can suppress stickiness.

In addition, if the absorbing magnetic elongated cellulose fiber absorbs sweat, the knitting and fine yarns constituting the fabric increase and become larger, and the density of the portion absorbing sweat decreases. It is possible to manufacture clothes that do not feel stuffy. When manufacturing the garment which does not feel such a frustration, the garment which is more effective in the knitted fabric side than a woven fabric is obtained. For example, the structure of a non-absorbable stretch fiber and a cellulose fiber can be manufactured by the price structure by arrange | positioning one strand absorption self-extension cellulose fiber in one strand alternation or three strands. As described above, in the present invention, by designing the absorbing magnetic elongated cellulose fibers effectively into a single circular knitting machine, a double circular knitting machine, a single warping knitting machine, a double warping knitting machine, a loom, etc., sweat is absorbed at the time of sweating during exercise or the like to form irregularities in the fabric. It is also possible to reduce the density of knitting or filament that make up the fabric of the absorbent part. In the case of warp knitting, a portion of the bobbin of the sinker loop is formed to have a longer length of the bobbin of the sinker loop, such as a cord (two stitches) and a satin (three stitches) than the cord, and this portion absorbs magnetic elongation. By arranging cellulose fibers and selecting a warp knitted fabric having these as one body, the effects of the present invention can be preferably achieved.

Furthermore, in the case of making the fabric, the surface of the warp or weft of the twill, satin or weft are long, or the surface layer and the double layer are woven as a double weave, and the connection part is provided every tens of strands in the direction of these warp and weft. The absorbent stretched cellulose fibers may be stretched when they absorb sweat to form irregularities in the fabric, or may be designed so as to reduce the density of the absorbed sweat portion. In these fabrics, the absorbent magnetic elongation cellulose fibers do not necessarily have to be exposed to the surface. For example, the absorbent magnetic elongation cellulose fibers are arranged in the intermediate layer as a three-layer structure, and the absorbent magnetic elongation of the intermediate layer is absorbed when sweat is absorbed. It is also possible to design the cellulosic fibers to stretch and push out the usual fibers of the outer layer to reduce the irregularities and density of the fabric.

In this way, by using the absorbent self-extension cellulose fibers, it is possible to produce a comfortable garment, especially during sweating, such as exercise. However, in the cellulose fibers having an absorption elongation of less than + 2%, the change in the fabric structure is small, and a comfortable garment cannot be produced even at the time of sweating such as exercise.

In the cellulose fiber blended fabric according to the present invention, it is preferable to contain 10% or more of absorbent stretchable cellulose fibers having an absorption elongation of + 2% or more, preferably + 3% or more. In the case where the mixing ratio of the absorbing magnetic elongated cellulose fibers is less than 10%, the effect of suppressing frustration is not effectively exhibited even when the cellulose fibers are elongated at the time of absorption. A more preferable mixing ratio is 15 to 100%, and a fabric of 100% absorbent stretched cellulose fiber can best exhibit the effect of the present invention.

However, when mixed with ordinary fibers such as cotton, acrylic, polyester, and nylon, problems such as texture and strength can be solved and developed in various kinds of medical treatments.

Although it is arbitrary about the mixing method of an absorbing magnetoextension cellulose fiber and a normal fiber, if the said cellulose fiber is arrange | positioned so that it may comprise independently in a course direction or a wale direction, an effect can be exhibited. For example, in the case of knit smooth tissue, absorbent stretched cellulose fibers are used for two consecutive courses, and all the loops in the course direction are made of absorbent stretched cellulose fibers, and adjacent courses are usually made of cotton or acrylic. By using the fiber, the effect of the present invention can be better exhibited. In the case of tissues in which all courses are made of one type of fiber in one course, such as a price structure, the effect of the present invention can be obtained by arbitrarily arranging the absorbent stretched cellulose fibers to have a mixing ratio of 10% or more.

Moreover, especially the cellulose fiber mixed fabric of this invention can obtain a high effect especially if the woven fabric has the part in which the welt loop and / or the tack loop by the absorbing magnetoextension cellulose fiber have the part formed continuously at least 2 loops. That is, the welt loop and / or tack loop by the said cellulose fiber are continuous in at least 2 loops in the course direction (fabric warp direction), the wale direction (fabric weft direction), or the diagonal direction in one needle bed. It is better to have the part formed.

Here, the tack loop and the welt loop are loops included in the knit loop, the tack loop, and the welt loop, which are three elements of the loop constituting the fabric. Tack loops refer to tissues that supply thread to a needle but do not knock over. Welt loops refer to tissues that do not supply thread to a needle. This tack loop, the welt loop, is almost straight or slightly curved in the fabric. Compared to a loop structure that is largely curved like a knit loop and has a large bending point in the lower part of the knit loop, when the absorbing magnetic elongated cellulose fiber is absorbed and elongated, the loop structure is small and there is no bending point.

Thus, since these tack loops or welt loops constitute the tissue of the fabric, the fabric density, or the filling rate, decreases upon absorption, thereby making the fabric free of air tightness. In particular, since the welt loop and / or the tack loop have a portion in which at least two loops are continuously formed in one course in the course direction, the wale direction, or the inclination direction, the effect of reducing air tightness during sweating is further increased. On the other hand, the double circular knitting machine has two needles of a dial and a cylinder, but is formed at least two loops continuously in a course direction, or in a wale direction and an inclined direction with respect to one needle structure only on the dial side or the cylinder side. It is good to design so that it may have a part, and the design of only one bed should be considered. In the case of a single circular knitting machine, since it is only a cylinder, it is not necessary to consider the structure design such as a double circular knitting machine, and if the welt loop and / or the tack loop by the absorbing magnetic-extension cellulose fiber have a part which is formed at least 2 loops continuously, do.

In addition, the combination of the tack loop and the welt loop can be arbitrarily used, and it can be set as the continuation of a tack loop, the continuation of a welt loop, or the combined continuous loop of a tack loop and a welt loop. For example, a welt loop, a tack loop in the course direction, a welt loop, a welt loop and two wales continue in the wale direction, and two welt loops in the wale direction, and a tack loop in the course direction thereof. It is possible to carry out two wale, etc. method. In addition, in the case of the so-called sheetstock structure in which the length knit loop in the wale direction is continuous, the sheetstock part is divided into 2 yarns and knitted, and it is set as the structure to complete 1 course by 2 yarns, and this is twice By carrying out continuously above, 2 loops are formed continuously in a diagonal direction, and the effect of this invention can be exhibited.

These are illustrated in Figs. 1 to 6, but in Figs. 1 to 6, [1], [2], and [3] indicate the knitting order and the course direction, and in practice, the fabric is knitted by repeating this knitting order. do. Weft rows show the wale direction. Although only four wales are shown in the figure, this organization is actually repeated. In addition, K represents a knitted structure, T represents a viscous structure, and W represents a welt structure.

1 and 2 show an example in which a welt loop or a tack loop is formed two consecutive times, and FIGS. 3, 4 and 5 show an example in which a welt loop or a tack loop is continuous in an oblique direction. The combined example is shown. On the other hand, when the tack loop or the welt loop is not continuous, the effect of the present invention is small.

In the case where the cellulose mixed fabric of the present invention is a warp fabric, it may be difficult to make use of the characteristics of the absorbent stretchable fiber depending on the structure. The present inventors conducted extensive studies to prevent this phenomenon, and found that a comfortable warp fabric can be produced by the warp fabric design method. That is, in the fabric containing the cellulose fiber absorbing self-extension, not only the cellulose fiber is looped, but also the shoring structure of 1 to 4 stitches, thereby achieving the object of the present invention.

The looping here is a structure in which a needle loop (knit loop) is formed. In the inserted tissue that does not form the needle loop, a so-called seam burst phenomenon occurs, in which deformation at the time of wearing the fabric does not return, which is not preferable. In the case of a structure in which looping and insertion are repeated, when the insertion is not continuous in only one course, the present invention regards it as a looping structure, and no bursting phenomenon occurs. However, when the insertion is continued for two or more courses, it is not easy to cause bursting. In addition, the effect of the invention is not obtained when knitted in the same wale as a chain knitting such as 10/01 without making the shogging structure. In the case of such a chain knitting, as in 10/01/12/21, a shogging structure is put once in two courses, and the chain knitting is designed so that the chain knitting is not continuous for two or more courses. Of course, the loop by binocular combination is also looping.

In addition, the shogging of the warp knitted fabric by the absorbing magnetoextension cellulose fiber needs to be 1-4 stitches. The more shogging, the more easily the moisture-proofing effect due to the absorption elongation of the cellulose fiber tends to occur. However, when the shogging becomes more than 5 knitting needles, the packing density of the cellulose fiber in the raw fabric becomes excessively high, and the effect of the moisture-proofing property is reversed when absorbing. This occurs. Therefore, shogging of the absorbent stretched cellulose fiber needs to be warp-knitted so as to have 1 to 4 stitches. For example, in the tricot of a two-piece body, the cellulose fibers are absorbed and elongated at the rear, and the normal fibers at the front, and the tissue at the rear is 10/12, 10/23, 10/34, Although shogging changes such as 10/45 and 10/12/10/34/32/34 are changed by course, all course looping or 12/00, 12/10/22/10/12/00 In addition to the repetition of looping and insertion, the insertion can be made into a structure such as a method of discontinuity.

In the present invention, in the case of the warp fabric containing the absorbent self-extension cellulose fibers, the cellulose fibers are extracted from the warp fabric, and the absorption elongation (the dimensional change rate at the time of absorption) of the cellulose fibers is measured as in the rear. This is often difficult except for tissues from which 10/12 tissue can be extracted. For this reason, the present inventors have examined the measure of changing the absorbed magnetic elongation and found that comfort of the worn fabric can be obtained by keeping the fabric density reduction rate within a predetermined value.

In particular, there is a correlation between fabric density reduction rate and wear comfort due to a small amount of water, and when 50% water content of the fabric weight is given to the fabric, the fabric density reduction rate is set to 5 to 40%, causing air to move in and out of the garment. It was found that the hygroscopicity and moisture-proofing property of cellulose fiber were fully exhibited by becoming easy, and air moved, and it did not become high humidity in clothes. The cloth density reduction rate at the time of absorbing the warp fabric of this invention is 5 to 40%, Preferably it is 10 to 30%. In the case where the fabric density decrease rate is less than 5%, it feels unpleasant at the time of wearing sweating and becomes unpleasant, which is not preferable. When the cloth density reduction rate is greater than 40%, the garment shape is changed too large, which impairs the feeling of wearing, and the appearance is also deteriorated, which is not preferable.

The warp fabric which is a cellulose mixed fabric of the present invention preferably contains 10% or more of absorbent stretchable cellulose fibers. As for the method of mixing the absorbent magnetoextending cellulose fibers and ordinary fibers, the method of alternately mixing the normal fiber and the absorbent magnetoextending cellulose fibers into separate beams, or the absorbing magnetoextending cellulose fibers and ordinary fibers There is a method of aligning a composite yarn to a beam as a composite yarn such as twisting, composite twisting, and interlacing. Further, the production of warp fabrics is possible by warp knitting machines such as single or double tricot machines and Russell machines. The tissue may be formed by any tissue, such as Denby, harp, satin, mesh jaw, three-dimensional jaw fabric having a connecting yarn inside the warp fabric, which is made of one or more bodies.

As the dyeing processing method of the fabric containing the absorbent self-extending cellulose fiber of the present invention, a normal dye finishing process can be used. As the dyeing machine to be used, in the case of alkali treatment of cellulose fibers in a fiber state, any dyeing machine such as a cheese dyeing machine, a bundle rotary dyeing machine, or an alkali treatment in the fabric state may be a liquid dyeing machine or a wince dyeing machine. Can be used. Moreover, it is also possible to use a continuous alkali treatment machine, such as a silk thread machine, which can process a textile continuously rather than a batch system. In this case, the processing conditions may be set as the conditions of the present invention. It is preferable to perform the dyeing | staining according to the dyeing conditions corresponding to a fiber raw material for the cloth after alkali treatment. Further, the processing in the fabric state is a pre-setting of the production machine by a pin tenter or the like at 150 to 190 ° C, followed by refining, alkali treatment, dyeing and finishing setting, and refining the vitality. And dyeing after pre-setting with a pin tenter at 150-190 degreeC, etc. can be performed by arbitrary processes, such as a process of carrying out a finishing setting. Although a finishing set is performed at 150-190 degreeC, in this case, what is necessary is just to complete | finish so that the cellulose fiber absorbed and extended after a finishing set may not produce a wrinkle or support. Moreover, the method of drying a fabric before finishing set and setting finishing density is preferable. Moreover, a softening agent and an absorbent can also be provided as a finishing agent, and provision of an absorbent is preferable because it improves sweat absorption. In addition, fiber resin provision, such as an absorbent, can also be provided during dyeing.

Hereinafter, the structure of the absorbent self-shrinkable cellulose fiber and the fabric of this invention using the said fiber is demonstrated.

The absorbent self-shrinkable cellulose fibers of the present invention have an absorption elongation of -2% or less. Making cellulose fiber into absorption elongation rate -2% or less is carried out by making the number of yarns into the twisted yarn of 8200-35000. As a result of repeating the examination of the fabric structure for achieving the object of the present invention, including the wear test, using the cellulose fiber, the fabric was made into two or three layers of circular knitting fabrics, and one side of the two or three layers circular knitting fabrics was used. In the outer layer or the middle layer, when the sweat absorbed the sweat during the sweating and the like, and when the sweat was absorbed in the other outer layer, the fiber having the small shrinkage was used, the flatness during drying was absorbed. At this time, the fiber of one outer layer shrinks, and the other outer layer is a small-shrink fiber, so it rises to form a convex, and when absorbed sweat and dried, the structure returns to a flat state. When the garment was sewn on the side, a conclusion was found to be comfortable even when sweating. Various studies have been made to achieve this function and found that this function can be achieved depending on the fabric structure and the specifics of the material.

That is, in order to express the effect of this invention, in the two-layer circular knitting fabric in which the separating part and the non-separating part are formed repeatedly, one outer layer contains absorbent self-shrinkable cellulose fibers, and the other outer layer contains non-absorbing shrinkage. The two-layer circular knitting fabric which consists of a fiber and the non-separation part of a course direction consists of a nonabsorbing shrinkage fiber is preferable. Here, the nonabsorbable shrinkage fibers are fibers having an absorption elongation greater than -2%, and include the aforementioned ordinary fibers and absorbing magnetoextending fibers. Cross-sectional views of such circular knit fabrics are shown in FIGS. 7 and 8.

Fig. 7 is a schematic cross-sectional view of the circular knit fabric when dried, and Fig. 8 absorbs sweat. In the circular knitted fabric, the separating portion 21 and the non-separating portion 22 are formed repeatedly, one outer layer A contains absorbent self-shrinkable cellulose fibers, and the other outer layer B is a non-absorbing shrinkable fiber. Consists of At the time of drying (FIG. 7), the surface of the fabric is flat, but when the sweat is absorbed (FIG. 8), the absorbent self-shrinkable cellulose fibers constituting (A) shrink, and the other outer layer (at the separating portion 21) The fibers constituting B) rise to form convex portions.

The separating portion and the non-separating portion may be repeated regularly or irregularly, and various structures and structures that can be produced by the circular knitting machine can be selected. On the other hand, in the circular knit fabric of the present structure, unlike the three-dimensional fabric of the other structure described later, the range of the cosby (A) / (B) of the two outer layers is not particularly limited, but to keep the surface of the fabric flat during drying In order to achieve this, it is preferable that approximately (A) / (B) = 1.

In addition, as a three-layer circular knit fabric capable of expressing the effect of the present invention, in a three-layer circular knit fabric in which the separating part and the non-separating part are formed repeatedly, one outer layer and / or the intermediate layer contain absorbent self-shrinkable cellulose fibers. The outer layer is preferably composed of nonabsorbable shrink fibers, and a three-layer circular knit fabric in which the non-isolated portion in the course direction is composed of nonabsorbable shrink fibers is preferable.

The shape of the separate portion of the multi-layer circular knitting fabric of two to three layers according to the present invention is arbitrary, such as a dot shape having an area of round shape, oval shape, square shape, rhombus shape, star shape, etc. It is arbitrary, such as a type | mold, a right upper inclination type, and an irregular shape. About the size of a separating part, even if it is too small or too big | large, the fabric unevenness effect at the time of sweating will reduce. In the case of a point shape having an area such as a rounded shape or a square, it is preferable that both the long diameter and the short diameter are 2 to 15 mm, particularly preferably 3 to 12 mm. In the case of the continuous type having a certain width, the width is preferably 2 to 15 mm, particularly preferably 3 to 12 mm.

The total area of the separation portion where the convex portion is formed when absorbing sweat is too sticky at the time of sweating even if it is too large. For this reason, it is preferable to make the total area which combined the area of each convex part in which the convex part is formed when absorbing sweat be 20 to 90% of the fabric surface at the time of drying. More preferably, it is 30 to 80%, and especially preferably 35 to 75%, there is no stickiness at the time of sweating and it becomes a comfortable garment.

The separation part in the 2-3 layer circular knit fabric of this invention is arbitrary shape as above. It is necessary that the non-separation part is formed so as to surround the separation part, and the separation part and the non-separation part are formed repeatedly.

The structural example of the separating part and the non-separating part of the said circular knit fabric is shown in FIG. The non-separating portion in the wale direction (circular knitting fabric warp direction) does not need to be continuous in a straight line, but the non-separating portion in the course direction (circular knitting fabric weft direction) is designed to be continuous in a straight line and consist of non-shrinkable fibers. That is, the non-isolated portion in the wale direction may contain absorbent self-shrinkable cellulose fibers, but the non-isolated portion in the course direction is composed of only the non-absorbed shrinkage fibers. The width of the non-separation portion in the wale direction is not particularly limited. About the width | variety of the non-separation part of a course direction, even if it is too narrow or too wide, since the stickiness reduction effect at the time of sweating becomes small, 1-15 mm is preferable. More preferably, 2 to 12 mm, particularly preferably 3 to 10 mm can fully achieve the object of the present invention, suppress the stickiness when absorbing sweat, and at the same time, costly linkage of 8200 to 35000 It is possible to reduce the mixing rate of the phosphorus cellulose fibers, thereby reducing the cost of the circular knit fabric. On the other hand, the width of the non-separation part is measured by the width of the non-separation part which is minimum in the course direction.

As an example of a specific manufacturing method of the two-layer circular knitting fabric according to the present invention, when using a double circular knitting machine, one outer layer is knitted and the other outer layer is knit knitted having two connecting layers of front and back every few days, The connection can be made of knit or viscous tissue. At the time of knitting, the outer layer contains absorbent self-shrinkable cellulose fibers. In order to provide a non-separation part which consists of the connection part of two outer layers partially in these structures, it is necessary to knit and connect with both a dial and a cylinder in the case of a double circular knitting machine using a nonabsorbing shrinkage fiber every several courses, and to make it a non-separation part. In this way, the separating portion and the non-separating portion are repeatedly formed in the course direction and the wale direction, and when the sweat is absorbed, it becomes possible to form a dot-shaped convex portion having an area such as a rounded shape or a square.

As an example of the specific manufacturing method of the three-layer circular knitting fabric by this invention, when using a double circular knitting machine, any one fiber which knits three layers every several wales, making the superficial layer and the back layer knit on a knit sheet, and the middle layer as a welt. Or by connecting all of the dials, cylinders by knit or tacking with all the threads, and by knitting the outer sheeting of one outer layer, the outer layer and the middle layer are integrated, and the other outer layer is made the sheeting. And a method of knit or tactile connection by any fiber constituting the present invention. There is also a method in which the intermediate layer is made of welt and plated, and the absorbent self-shrinkable cellulose fibers are arranged in one outer layer and the intermediate layer. In the case of such circular knitting, non-absorbing shrinkable fibers are knitted every few courses, dials, and cylinders every several courses to form non-separating parts in the course direction and the wale direction. The point-shaped convex part which has an area can be formed.

The absorbent self-shrinkable cellulose fibers according to the present invention are twisted so as to have a linkage of 8200 to 35000. Since the cellulose fiber is twisted in the number of lines 8200 to 35000, the function of shrinking when sweat is absorbed can be exhibited. If the number of linkages is less than 8200, the target function of the present invention cannot be exhibited, which is not preferable. When the number of linkages is larger than 35000, it is not preferable because the circular knitting fabric becomes difficult and the cost is high. Therefore, the number of linkages may be set to 8200 to 35000, preferably 11000 to 30000.

In this invention, it is preferable that the absorbent self-shrinkable cellulose fiber is mixed 5 weight% or more of the whole multilayer circular knit fabric. If it is less than 5% by weight, the convex formation of the circular knit fabric is very small when the sweat of the present invention is absorbed, so that the object is difficult to achieve, which is not preferable. In addition, even when the mixing ratio is more than 50% by weight, it is not preferable because the shrinkage increases when the sweat of the entire circular knit fabric is absorbed and the garment size changes. The mixing method of the absorbent self-shrinkable cellulose fibers is arbitrary, and a method of arranging fibers, a method of making twisted yarns with ordinary fibers, and the like can be performed.

Since the total area of the part where the convex part is formed when absorbing sweat is excessively at least excessively sticky at sweating, the total area of the convex parts of the side where the convex part is formed when absorbing sweat is summed up, It is preferable to set it as 20 to 90% of the surface of the fabric at the time of drying. More preferably, it is 30 to 80%, and especially preferably 35 to 75%, there is no stickiness at the time of sweating and it becomes a comfortable garment.

The fabric density of the multi-layer circular knit fabric of 2-3 layers in the present invention can be arbitrarily set.

The dyeing treatment method of the circular knitting fabric of the two to three layers of the present invention can be used a normal dyeing finishing step, the dyeing conditions corresponding to the textile material to be used, and the dyeing machine to be used is arbitrary, such as liquid dyeing machine, wince dyeing machine and the like. . Moreover, in order to improve water absorption, it is preferable to provide an absorbent, and as an example of the dyeing finishing process, after putting a raw material into a dyeing machine, performing scouring and dyeing, it also serves as a finishing process, such as an absorption process, and performs a finishing setting, Or it can carry out by arbitrary dyeing finishing processes, such as the method of performing wet relaxation process, dyeing after presetting, and performing final setting which also served as the finishing process.

10 and 11 show other preferred embodiments of absorbing self-shrinkable cellulose fibers in addition to the above-described aspects, which form a three-dimensional structure fabric in which the fabric is partially separated and an air layer is provided between the two outer layers.

Fig. 10 is a schematic cross-sectional view of the three-dimensional structure fabric when absorbed sweat when drying. The fabric is formed by the separating portion 21 and the non-separating portion 22 repeatedly, one outer layer (C) contains the absorbent self-shrinkable cellulose fibers, the other outer layer (D) is composed of non-absorbing shrinkage fibers It is. Different from the above configuration, the fabric surface has convex portions at the time of drying (Fig. 10). This is obtained by knitting so that the number of courses of two outer layers becomes (C)> (D). When the fabric surface has convex portions during drying, the thickness of the fabric increases, and because of the presence of the air layer, when it is warm and absorbs sweat (Fig. 11), the absorbing self-shrinkable cellulose fibers constituting (C) shrinks, The convex portion at 21 decreases, and the heat dissipation is increased because the thickness of the fabric and the air layer decrease. After absorbing the sweat and drying, the convex part is restored and returned to its original thickness.

In other words, it is warm in the state of not sweating, heat dissipation proceeds at the time of sweating, and since extra sweat is not sweated, the movement function is less likely to decrease and a comfortable fabric is obtained.

Specifically, in the three-dimensional fabric in which the separating portion and the non-separating portion are formed repeatedly, one outer layer (C) constituting the separating portion contains absorbent self-shrinkable cellulose fibers, and the other outer layer (D) The object of the present invention can be achieved by a three-dimensional circular knit fabric containing non-absorbing shrinkage fibers and having a course number of two outer layers (C) > (D). In addition, the three-dimensional fabric of the present invention is a structure in which one outer layer (C) constituting the apparent separation portion rises to form a convex portion, and the non-separation portion connecting the separation portion and the two outer layers is regular or irregular. The structure is repeated. Such a structure can be selected from various structures and structures that can be produced by a circular knitting machine. When sweat is absorbed, the outer layer containing the absorbent self-shrinkable cellulose fibers shrinks to decrease density, and convex portions become smaller (textiles). It can be made into a tissue (thinning thickness).

In such a three-dimensional structure fabric, the shape of the separation part that is partially separated is arbitrary, such as a point shape having an area such as an oval, a square, a rhombus, a star, etc., in addition to a rounded shape, and also checks the arrangement of the checkered shape and the right upward slope. Random, irregular, etc. are arbitrary. Regarding the size of the separating part, the effect of reducing the convex part when absorbing sweat decreases even if it is too small or too large. In the case of the point shape which has area, such as round shape and a square, it is preferable to set both long diameter and short diameter to 2-15 mm, Especially preferably, it is 3-12 mm. In the case of the continuous type having a certain width, the width is preferably 2 to 15 mm, particularly preferably 3 to 12 mm.

Moreover, when the total area of the separation part in a three-dimensional structure fabric is too small, since the thickness reduction effect at the time of sweating is small, it is preferable to set it as 20% or more of the surface of a circular knit fabric. More preferably at least 30%, particularly preferably at least 40%, the effect of reducing the thickness at the time of sweating is great, and the amount of heat dissipation increases, resulting in a comfortable garment capable of anticipating the sweating effect.

The separating part in the three-dimensional structure fabric of this invention is arbitrary shapes as mentioned above. The non-separation part needs to be formed so as to surround the separation part, and the separation part and the non-separation part need to be formed repeatedly. About this non-separation part, you may consist of any one fiber contained in a separation part, or may interchange these, and may be comprised by the thread different from a separation part. For example, the non-isolated portion in the wale direction may contain absorbent self-shrinkable cellulose fibers, and the non-isolated portion in the course direction may be composed of only the non-absorbed shrinked fibers. The knitted structure can use any structure as long as it is a structure knitted using both needle-like cylinders of a circular knitting machine cylinder and a dial, such as a smooth and a price. In the non-isolated portion, the more non-absorbing shrinkage fibers are contained, the lower the mixing ratio of the cellulose fibers as the three-dimensional structure fabric, and the superior fabric is in terms of cost and fastness.

In the three-dimensional fabric of the present invention, the ratio of the number of courses of (C) and (D) is preferably (C) / (D) of 1.1 to 5.0, more preferably 2.0 to 4.0. When the ratio of the number of courses is 1.1 or more, the convex portion is likely to be expressed in a normal state in which no sweat is absorbed, and the effect by the thickness reduction of the convex portion can be sufficiently exhibited when the sweat is absorbed. Moreover, when the comparison of courses is 5.0 or less, the convex part in a normal state tends to be formed beautifully, and the convex part reducing effect at the time of absorbing sweat is also clear, and it is preferable also from a productivity point of view. On the other hand, when the number of courses on the outer layer of the separating portion is not constant between wales, the number of courses with the highest number of courses is taken as the number of courses. In addition, the number of courses measures only the knit loop, and the tack loop and the welt loop do not count as the number of courses. However, these are applied when the sizes of the knit loops of the two outer layers are almost the same, and when the sizes of the knit loops of the two outer layers are different, they are calculated in terms of the same size of the knit loops as the two outer layers. For example, when the size of the knit loop of one outer layer C is half the size of the other outer layer D, (C) x 2 is treated as calculation (C). In addition, the size of a knit loop is calculated | required by the incorporation length which comprises a separation part.

In the three-dimensional structure fabric of the present invention, one outer layer (C) constituting the separation portion may contain absorbent self-shrinkable cellulose fibers, and may alternate with nonabsorbable shrinkage fibers. As the alternating method, a method of alternately knitting the absorbent self-shrinkable cellulose fibers and the non-absorbing shrinkable fibers, a method of attaching the thread with the non-absorbing shrinkable fibers, and the like can be used. It is preferable to set it as a rate. If it is less than 15 weight%, when the sweat is absorbed, the thickness phenomenon of the convex part is small and it is unpreferable. Especially preferably, it is a mixing rate of 20 weight% or more.

Moreover, although the other outer layer D which comprises a separation part is comprised mainly from non-absorbing shrinkage fiber, it may contain a small amount of absorbent self-shrinkable cellulose fiber. It is preferable that the mixing rate of the absorbent self-shrinkable cellulose fibers is less than 5% by weight, and in the case of the mixing rate of 5% by weight or more, the effect of reducing the convex portion when absorbing sweat is not preferable. It is preferable that all of them consist only of nonabsorbable shrinkage fibers.

Moreover, it is preferable that it is 5-50 weight%, and, as for the mixing rate which occupies for the whole three-dimensional fabric of the cellulose fiber of linkage number 8200-35000, it is more preferable to set it as the mixing rate of 10-30 weight%. If less than 5% by weight, the convex reduction of the circular knitting fabric of the present invention is very small when absorbing sweat, and if it is more than 50% by weight, the shrinkage of the entire three-dimensional structure fabric becomes large when the sweat is absorbed, which is undesirable. not. The mixing method of the cellulose fiber of 8200-35000 of linkage is arbitrary, The method by arrangement | positioning of a fiber, the method of making into a composite yarn with a non-shrinkable thread, etc. can be performed.

Production of the three-dimensional structure fabric in the present invention can be produced in a circular knitting machine, and can also be arbitrarily set for the circular knitting fabric density.

The three-dimensional fabric according to the present invention uses a double circular knitting machine as an example of a specific manufacturing method, partially uses absorbent self-shrinkable cellulose fibers in the sheeting part of the cylinder, and the number of courses of the separating part of the cylinder is larger than the number of courses of the dial. Losing organization. At this time, it is also possible to use the absorbent self-shrinkable cellulose fibers alone or to attach the yarn with ordinary fibers such as polyester and nylon. In addition, a non-separation part is required between the separation part and the separation part. By providing the non-separating portion, the separating portion and the non-separating portion are formed repeatedly in the course direction and the wale direction, thereby making it possible to form a dot-shaped convex portion having an area in the three-dimensional structure fabric, and the thickness of the convex portion decreases when sweat is absorbed. The heat dissipation effect can be improved.

A normal dye finishing process can be used for the dyeing treatment of the three-dimensional fabric of the present invention. The dyeing conditions used according to the textile material used are arbitrary, and the dyeing machine used is arbitrary, such as a liquid dyeing machine and a wince dyeing machine. Moreover, in order to improve water absorption, it is preferable to provide an absorbent. As an example of a dye finishing process, a vitality is put into a dyeing machine, and after refine | purifying and dyeing, it performs the finishing setting also as a finishing process, such as an absorption process, or a wet relaxation process, dyes after presetting, and finishes a finish process. Although arbitrary dyeing finishing processes, such as the method of performing the finishing setting, also can be performed, care should be taken in setting the width and the length in the finishing setting, and the convex part in which the outer layer containing the absorbent self-shrinkable cellulose fibers is formed is maintained. You need to finish it.

Subsequently, only the ester side was dyed at 130 degreeC. Since the fabric of the dyeing ups and downs was uneven | corrugated, after using a short loop dryer, it extended | stretched so that the wrinkles of a cloth might disappear in a pin tenter, it finished on the conditions of 170 degreeC and 60 second, and set. On the other hand, at the same time as the dyeing in the liquid dyeing machine was given an absorbent. The obtained fabric was a structure in which a tack loop was formed continuously in the course direction.

It was +5.7% when the cupra fiber of the obtained fabric was taken out and the absorption elongation was measured.

The T-shirt was sewn using the obtained fabric, a wear test was done, and the wearing result is shown in Table 2.

Example 19

When knitting a half-tissue using a 28-gauge single tricot knitting machine, W-shaped cross-section yarn of polyester 56dt / 30f is disposed as a regular fiber in the front, and cupra fiber 56dt / 30f as a cellulose fiber is placed in the rear, and All-in threading was arranged to arrange the needles in the needles. In this case, the cupra fibers used are ordinary cupra fibers without alkali treatment.

The knitted vigor was placed in a liquid dyeing machine, refined at 80 ° C. for 20 minutes, and after draining, alkali treatment was performed at 30 ° C. for 20 minutes in an aqueous 50 g / L sodium hydroxide solution. This was followed by dyeing the polyester fibers and cupra fibers. Since the fabric of the dyeing ups and downs was uneven | corrugated, after using a short loop dryer, it extended | stretched so that the wrinkles of a cloth might disappear in a pin tenter, it finished on the conditions of 170 degreeC and 60 second, and set. On the other hand, during liquid dyeing, an absorbent was applied simultaneously with dyeing.

It was 17.8% when the fabric density reduction rate of the obtained warp fabric was measured, and it was +5.8% when the cupra fiber of the obtained fabric was taken out and the absorption elongation was measured.

Moreover, the T-shirt was sewn using the obtained fabric and the wearing test was done. The wearing results are shown in Table 3.

[Examples 20 to 22]

In Example 19, the warp fabric was produced by changing the structure to change the shogging amount, mixing ratio, and roofing of the cellulose fibers. The wearing comfort of the fabric using these was evaluated. The results are shown in Table 3.

[Example 23]

The tissue of FIG. 14 was organized using the 28-gauge circular knitting machine. In 1, 2 heater combustible yarn of 84dt / 36f polyester fiber was used as a normal fiber, and 2 was cupra fiber 84dt / 45f of 18000 linkages. After repeating 1-2 times 10 times, the structure | tissue of the non-separation part of FIG. 9, R was knitted so that it might become 4 mm in finish width using the non-shrinkable 2 heater combustible yarn of the polyester fiber of 56dt / 24f.

The knitted vigor was placed in a liquid dyeing machine, refined at 80 ° C. for 20 minutes, and then stained only at the ester side at 130 ° C. Since the cloth of the dyeing ups and downs was made into the uneven | corrugated type | mold, width setting was performed at 170 degreeC and 60 second until the convex part extended in the pin tenter.

The T-shirt type was sewn with the obtained fabric, and the comfort test at the time of exercise sweating was done. The results of the wear test are shown in Table 4.

[Examples 24-27, Comparative Example 2]

In Example 23, the fabric was manufactured using the cellulose fiber which changed the number of links shown in Table 4, and was produced by changing the width | variety of a non-separation part, and evaluated these. The results are shown in Table 4.

[Example 28]

The tissue shown in Fig. 15 was knitted by a 28-gauge circular knitting machine. In 1, 2 heater twisted yarns of polyester fiber of 84dt / 36f were used as a normal fiber, and the main body of the sheeting structure was partially connected to the cylinder side and the viscous structure. In the 2, two heater combustible yarns of polyester fibers of 56dt / 24f polyester fibers and attachment yarns of cupra fibers 84dt / 45f of linkage 18000 were used as ordinary fibers. After repeating 1-2 times 10 times, FIG. 10 and the non-separation part R were knitted so that it might become 5 mm in finish width | variety with the price structure using the 2 heater combustible yarn of the polyester fiber of 56dt / 24f as a normal fiber.

The knitted vigor was placed in a liquid dyeing machine, refined at 80 ° C. for 20 minutes, and then stained only at the ester side at 130 ° C. Since the cloth of the dyeing ups and downs was made into the uneven | corrugated type | mold, width setting was performed at 170 degreeC and 60 second until the unevenness | corrugation increased in a pin tenter.

T-shirt type was sewn from the obtained fabric, and the comfort test at the time of exercise sweating was done. The results of the wear test are shown in Table 4.
