DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a woven fabric excellent in water absorption, water permeability and stretchability, and more particularly to a woven fabric having a structure in which the back surface of the woven fabric is in point contact with the back surface. The present invention relates to a woven fabric, which absorbs and diffuses water from the surface, transmits water to the surface, has a good texture, and has elasticity in the lateral direction, and is most suitable for comfortable wear.

[0002]

2. Description of the Related Art Conventionally, polyester fiber is a synthetic fiber because it is hard to wrinkle, has excellent pleatability and dimensional stability, and has many excellent properties such as drapeability, tension, waist and rebound. Used as the mainstream of
In particular, it is widely used in the women's clothing field. Until now, new textures have been required for changes in fashion trends from the aspect of affluent lifestyles along with the rapid growth of the economy, and the development of new yarns for textiles has been carried out one after another, and it has settled on the market as a new synthetic fiber. did. In addition, opportunities for sports have expanded due to an increase in leisure time, and clothing has been expanded to so-called sports fashion worn for watching sports in addition to actually wearing sports.

[0003] As a material used in sports clothing up to now, a stretch function has been required for do sports, and knits have been mainly used. As a further enhancement of functionality, fabrics having a water permeability function for comfort are disclosed in Japanese Utility Model Publication No. 61-27990 and Japanese Utility Model Publication No. 62-2.
No. 9496 and many other proposals have been made, but most of them are related to the design of water absorption and water permeation functions by knitted fabrics, and they do not have the luxury of garment appearance and silhouette. At present, there is no material that meets the requirements.

[0004] Knits have a stretch, waist and resilience characteristic like a woven fabric due to their fabric structure, and it is difficult to obtain a drapeable fabric. Not suitable for silhouettes. Especially for golf, a sporty casual feeling is required, and conventional knits do not provide relatively thin fabrics with tension, waist and resilience, so there is a strong demand for fabrics, silhouettes are sporty casual, Further, as a wearing comfort function necessary for do sports, a material having both sweat absorption, quick drying and stretchability is required.

[0005] Further, it is clear that the society will shift to an aging society, lifestyles are changing from the past, and demands for health care are increasing in response to changes in the social environment. In particular, in the future, as a nursing care clothing, there is a strong demand for a medium-thin fabric that has various functions required for both the caregiver and the caregiver, and that can be further worn to obtain an elegant style. There is a tendency.

A design for obtaining water permeability, which is one of the wearing comfort functions, is proposed in, for example, the above-mentioned Japanese Utility Model Publication No. 61-27990, but here, a non-hygroscopic fiber yarn is provided on the surface of the fabric. The basic principle is to use the fineness gradient difference between the yarns constituting one side and the other side, that is, to increase the fineness on the water absorption side and make the diffusion side thin.

When a cloth is worn as a garment, there is a strong demand that the side in contact with the skin be soft, whereas a woven fabric tends to feel stiffer than a knit even with the same fineness due to the weave structure. However, a woven fabric having a large fineness cannot be used. Therefore, in order to obtain a soft touch and to obtain comfort when worn due to a water absorbing effect and a diffusing effect, it is necessary to further improve the comfort because there is no hygroscopicity when using 100% non-hygroscopic fiber. There is a possibility that unpleasant sensation may remain, and even if a hygroscopic fiber is used, it is necessary to improve the structure so as not to leave unpleasant sensation by absorbing and diffusing water structurally.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the present invention will be described.

In the present invention, a woven structure having a multiple structure such as a double woven structure is used in order to obtain a woven fabric having a water absorption and diffusion, a water permeation effect, a natural surface feeling and drapability, and a soft touch.

As the double weave structure, a warp double weave structure, weft 2
A heavy weave organization and a warp / weft double weave organization can be adopted. In order to give the woven fabric a water-permeability effect, it is possible to increase the water-absorbing performance in the same way as with knits by increasing the difference in the fineness gradient between the front and back, and increasing the fineness of the backside The fabric has a hard touch and lacks comfort in wearing. From such a point, it has become possible to achieve the demand by repeatedly examining a fabric having a water absorbing and diffusing effect as a feeling of wearing comfort and having a soft touch. In the present invention, a double-woven structure is preferably used, but as long as the effects of the present invention are not impaired, a three-woven structure is preferably used.
A multi-layer structure having a weight or more can also be used.

First, the yarn and woven structure used in the present invention will be described.

A short fiber spun yarn is used for the warp constituting the surface side of the woven fabric of the present invention, and the weft has stretchability such as false twisted yarn or conjugate yarn for imparting stretchability. Use multifilament yarns or covering yarns, including spandex yarns such as polyurethane-based. As the warp constituting the back side of the woven fabric, a multifilament yarn, preferably a multifilament yarn mainly having a multi-leaf cross section is used. Here, the conjugate yarn is a yarn having a crimp developing ability in which two or more different polymers are joined in parallel or in a core-sheath manner in a fiber cross section.

Examples of varieties of spun yarns used for warp yarns on the front side include synthetic fibers such as polyamide fibers such as nylon 6 and nylon 66 and polyester fibers such as polyethylene terephthalate, polypropylene terephthalate and polybutylene terephthalate, and natural fibers. Although it is used, the type is not particularly limited. In addition, hydrophobic fibers are preferably used for the warp yarn constituting the back side, and polyester fibers such as polyethylene terephthalate, polypropylene terephthalate, and polybutylene terephthalate are particularly preferably used as the type of multifilament yarn. The short fiber spun yarn and the multifilament yarn used for these warps are arranged and warped. In this case, the warp or the weft constituting the front side is not arranged (1: 1) on the entire back surface. It is preferable to arrange them at an interval. Preferably, the relationship between the front side warp and the back side warp is 2: 1 to 12: 1, most preferably 3: 1 to 6: 1.

For example, as shown in FIG. 1, two types of warp yarns are used, and one type (vertical warp yarn 1) is organized with the weft yarn 2 to form the front and back surfaces of the woven fabric by a warp (yarn) double structure. . The other type (back warp yarn 3) constitutes a part of the warp yarn on the back side of the woven fabric, and is woven with the weft yarn so as not to be on the front side to form a joint point. That is, the warp and the weft constituting the table are visible on the surface, and another kind of the warp is arranged for every several warps constituting the table on the back side. In the case of a double structure, the yarn constituting the back surface is more likely to appear on the back surface. That is, one type of warp constitutes the front and back surfaces of the woven fabric, and the other warp is arranged every few lines, and one type of weft intersects both warps to constitute the woven fabric. It is preferable that the relationship between the warp on the front side and the warp on the back side be 2: 1 to 12: 1.

According to this arrangement, when the back side of the woven fabric is used as the back side of the garment, the texture points on the back side are configured as if stepping stones are formed, and point contact is made with the skin which is the contact surface. It absorbs and diffuses easily, giving a softer touch.

In the present invention, when a yarn containing hydrophilic (hygroscopic) fibers is used as a type of warp yarn on the surface side, even if the woven fabric absorbs and diffuses due to perspiration, etc. Since the back side warp is in contact with the skin surface and the hydrophilic fiber of the front side warp does not directly contact the skin,
There is no unpleasant feeling of wetting, and conversely, before sweating, the humidity of the fabric and the skin surface is high, that is, until the sweat comes out from the skin, the humidity is adjusted by the hydrophilic fiber by the moisture releasing effect This has the effect of contributing to a comfortable feeling.

Next, in the case of the comparatively medium-thin fabric, the fabric is excellent in water absorption / diffusion performance, is tailored to a sewn garment, and has a silhouette suitable for sporty casualness. It is necessary to design a fabric having tension, waist, rebound and drape. Elements will be described.

In order to quickly absorb water from the back side of the woven fabric and to diffuse the absorbed water to the front side as quickly as possible, the fineness of the single yarn of the yarn constituting the front side in the double-woven structure structure is small. The larger the single fiber fineness of the yarn constituting the back side, the better the so-called fineness gradient difference, the better. However, on the other hand, from the viewpoint of wearing comfort, a soft touch is required in addition to the water absorption. In a woven fabric, it is generally said that when the single fiber fineness is 3 dtex or more, the skin is usually hard to feel. 3dtex for the necessary fabric tension
The above single fiber fineness is preferably required. When the single fiber fineness is large, a yarn having a shape in which the arrangement of the single fibers is disturbed, such as the so-called “taslan” processing of false twist processing or fluid turbulent flow processing, is useful. In addition, when the single fiber fineness is 3 dtex or less, a yarn having a modified water-absorbing effect or a multi-leaf cross-sectional shape having a high water-absorbing effect can be used as the yarn having a high water-absorbing effect. As the irregular cross-sectional shape or the multi-leaf cross-sectional shape, a flat yarn having a triangular to hexagonal cross section, C, H, L,
Any of U and X-shaped cross sections, which are directly formed from a spinneret, or a method of spinning into a fabric by composite spinning and then forming a deformed cross section by reducing the amount of alkali in a dyeing step may be used.

When short fiber spun yarns are used in combination with other yarns as in the woven fabric of the present invention, it is preferable to use modified cross-section yarns having a large water absorbing effect.
Furthermore, since the polyester itself is hydrophobic, the converged multifilament yarn is excellent in water absorption from the cross section of the fiber, as seen in the water absorption effect by the birec method, but from the side of the fiber. Poor water absorption. In order to enhance the water-absorbing effect from this side, in the dyeing process, a method of reducing the amount of alkali is used. In addition, a difference in molecular arrangement height in the length direction of the polyester multifilament yarn such as T & T (thick and thin) is obtained. Using raw yarn with
This may be subjected to alkali reduction treatment to generate cracks (cracks) on the side surfaces of the fibers.

Further, in order to improve comfort when worn, a polyester multifilament yarn obtained by spinning a polymer obtained by adding ceramic particles represented by titanium oxide to a warp constituting the back side of the fabric is used. Is preferred. By using this multifilament yarn, when the woven fabric comes into contact with the skin surface, a cooling effect, that is, a contact cooling / heating effect can be obtained. Ceramics such as titanium oxide are preferably mixed in a ratio of 1 to 7 with the original yarn.
% By weight, more preferably 2 to 6% by weight. If the ceramic content is less than 1% by weight, the cooling effect is poor,
On the other hand, if it exceeds 7% by weight, there is a problem in the spinnability of the raw yarn for clothing, which is not preferable. Further, by using the ceramic-added raw yarn on the front side of the woven fabric, a UV cut effect can be obtained, which is more preferable.

Further, in order to give an effect to the tailored silhouette, it is preferable to twist the multifilament yarn used for the warp yarn. The level of the number of twists is the number of twists: T
(T / m), fineness of multifilament yarn: D (dte
x), when the twisting factor is α, the twisting factor is calculated by the following equation: α = T × D ^1/2 , and the twisting factor α is preferably 1,000 to 1
8,000, more preferably 2,000 to 1
5,000.

In order to enhance the quality with a sense of quality, the yarn type and the fabric structure constituting the surface material are important. As described above, the spun yarn is basically a spun short fiber yarn. The short fiber spun yarn may be 100% of a hydrophobic fiber, or may be any of a blended yarn of a hydrophobic fiber and a water-absorbent fiber and a composite yarn. In particular, the former is suitable for applications requiring a water-repellent effect, and the latter composite yarn typified by polyester / cotton blend yarn is applied to applications requiring comfort due to moisture absorption, such as shirting and uniforms. it can.

As for the composition of the short fibers, the smaller the single fiber fineness is, the better the difference in the fineness gradient with the yarn constituting the back side is. However, it is not suitable for the sporty casual feeling of the sewn product. You have to choose. For example, even if the single fiber fineness is 1 dtex or less, the woven fabric structure can be free from pilling and other physical problems, and in some cases, can be improved by increasing the number of twists of the spun yarn. Also, even if the difference in fineness gradient from the back side becomes smaller, the point contact structure with respect to the contact surface on the back side allows
The effect of comfort can be covered. Further, in the case of a spun yarn of a synthetic fiber, it is possible to widely cope with a change in demand by a structure variation due to a blending of raw cotton having different dyeing properties or an arrangement in a weaving process.

In the present invention, when the woven fabric structure on the front side has a lot of warp floats, by using a spun yarn having a modified cross section having a high water absorbing effect as the weft to be used, the water absorbed from the back side can be reduced. The diffusivity on the front side can be increased.

In the case of the composite structure woven fabric according to the present invention, warp preparation, sizing, and beaming are performed as a warp preparation. For example, in the case of a warp double weave structure, the warp constituting the back surface side does not appear or disappear between warp yarns on the front surface side. And the design considering the connection point
Tension control during weaving is important. Others are woven based on a general spun yarn weaving process. On the other hand, with regard to the multifilament yarn, by paying close attention to the handling, it is possible to produce a fashion woven fabric that requires a high quality.

In the present invention, it is important to have a stretch property which is important for comfort as well as a function of water absorption and quick drying. In a warp double structure such as the woven fabric, the number of warp yarns is large, the degree of freedom in the woven fabric is reduced, and the elongation of the woven fabric is reduced, so that puckering is likely to occur at the time of sewing, resulting in poor tailoring. Furthermore, there is a tendency that the comfort when wearing is not good because there is no room in the fabric. For this reason, it is extremely important to provide elasticity in the lateral direction. As a means for imparting this stretch property, a stretchable yarn is used. Usually, the use of a multi-filament false twisted yarn can provide a stretch property of 5 to 15%, which is advantageous in that the cost is low. In addition, by using a twisted conjugate yarn as the multifilament yarn, a stretch property of about 5 to 20% can be obtained, the cost is reasonable, and there is a merit that the swelling of the fabric and the tailoring appearance due to resilience are excellent. . Furthermore, there is a problem in cost due to the use of polyurethane-based spandex covering yarn.
High stretchability of 0% or more is obtained. These weft types are appropriately selected according to the stretch level and cost required for the garment.

In the woven fabric of the present invention, the dyeing process can be carried out in a standard step of a usual short fiber woven fabric. The alkali reduction treatment is selected for the raw yarn used. Tension, waist, which contributes to the function of water absorption / diffusion and tailoring of the fabric
In order to finish the texture with both resilience and drape,
Processing is performed by setting the conditions of each process optimally. Also,
Due to the functionality of water absorption and diffusivity, an optimal finishing agent is used in finishing.

Further, as an element that can meet even higher requirements, in the woven fabric of this design, a water-repellent treatment can be performed only on the surface of the woven fabric. can do.

Next, the performance of water absorption / diffusion of the woven fabric and its evaluation method will be described.

As comfort, water absorption from the back side of the fabric and diffusion to the front side are quantitatively and visually judged.

As a quantitative measurement method, the following two evaluation methods are used. (1) Back surface drop water absorption time: The water absorption rate according to the drop method in JIS L1907 "Test method for water absorption of textiles" is used. (2) Front and back diffusion area ratio: As a sample, three 10 cm × 10 cm woven fabrics are collected. B. B. 0.1 cc ink stock solution (produced by pilot) is dropped on the dough. After leaving for 3 minutes, copy the diffusion state of the dough surface and the back of the dough onto paper. E. Read the area of the copied paper with a digital planimeter (KP-90, manufactured by Uchida Yoko) and calculate the average value of the three sheets. From the front and back diffusion area obtained above, the front and back diffusion area ratio is calculated by the following equation.

Front / back diffusion area ratio = S1-S2, where S1: front diffusion area value S2: back diffusion area value The visual evaluation method is as follows:
Not only the front and back diffusion area ratio, but also a functional evaluation scale determined by the sensory concept of the present invention, refers to a sample in which the back surface state of the water absorption diffusion sample is in a point contact state after water absorption diffusion.

The criterion for accepting the effect in the present invention is that the smaller the back surface drop water absorption time in the above (1), the higher the effect is, 5 seconds or less, and the above (2) the front / back diffusion area ratio. 2 times or more, and the way of applying ink is on point contact.

The measuring method of the stretchability of the fabric is JIS L10.
Method A (constant speed elongation method) generally adopted for the evaluation of “stretchability of stretchable fabric” in 96 (General fabric test method)
It is obtained by measuring.
