Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a textured fabric used for clothing and bedding.

[Conventional technology]

The method of bonding two pieces of fabric together to form one piece of fabric is well known as the bonding method. In other words, the bonding method complements the defects of the other fabric by bonding two fabrics with different physical properties, appearance, manufacturing method, cost, etc., and improves tensile strength, abrasion strength, moisture absorption feel, shape stability (non-uniformity), etc. It has the advantage of efficiently producing a sublime double-layered fabric with excellent physical properties such as shape deformation, non-breathability, and heat retention, and therefore improves the physical properties of relatively thin single-layered fabrics. It is commonly used as a means or a means for producing thick fabrics similar to double woven or double knitted structures,
The resulting bonded double fabrics include thick knitted fabrics that are made by bonding knitted fabrics and non-woven fabrics and have low breathability and heat retention with little stretch, and synthetic fiber fabrics and natural fiber fabrics that are bonded together. There are thick ones that have both abrasion resistance and moisture absorption properties, and have high heat retention, and those that have an outer material and interlining that are bonded together and have excellent shape stability and do not easily lose their shape. Because it has a two-layer structure, it has a hard texture, which is suitable for so-called industrial materials such as men's clothing fabrics that do not want to lose their shape and fabrics for bags and bags that emphasize physical properties and functions, but soft texture is important. It could never be used in summer women's clothing and was considered completely unrelated.

Therefore, it has never been considered to produce a grained fabric by the bonding method.

Textured fabrics include fabrics made by partially pinching and setting fabrics, willow or crepe with fine warp wrinkles, partially changing the tension or feed amount of the warp threads, or partially chemically treating the fabrics. There are some that have been partially shrunken, and some that have been wrinkled irregularly by washing machines or dyeing machines.

In addition, Japanese Patent Publication No. 59-53927 and Japanese Patent Publication No. 50-53930 disclose a technique in which a raw material consisting of two or several types of yarns with different shrinkage rates is subjected to shrinkage treatment to raise low-shrinkage yarns. There is.

[Problem that the invention seeks to solve]

Shibori is extremely inefficient because it is done by hand, and the grains on willow and coupe are fine, solid-colored and lack interest as patterns, and the wrinkles created by washing machines and dyeing machines are temporary and will disappear. easy.

Depending on the size, the tension or feed amount of the warp yarns can be partially changed, or the warp can be created using the difference in shrinkage of the yarns.Several types of yarns can be warped into separate beams and set on a knitting loom for tensioning, etc. have to be controlled separately, which complicates material (yarn) management and management and adjustment of knitting and loom machines.As these several types of yarn alternate every few yarns and are arranged straight vertically and horizontally, the grain is It is uniform and has a plain color tone, and if tension unevenness or thread breakage occurs in the arranged threads, the grain in the arrangement direction will create irregular striped flaws. Furthermore, since the threads in the raised areas must be strongly gripped by the threads in the non-raised parts, these several types of threads that make up the fabric are tightly intertwined and connected. Therefore, it is difficult to obtain a textured fabric with coarse weft and weft density. However, since several types of threads are warped into separate beams and placed on a knitting loom, the production lot is large, making it unsuitable for high-mix, low-volume production in response to trends. Although it is possible to produce small lots of uneven fabrics with a honeycomb knitting structure using a circular knitting machine, such fabrics have a high degree of elasticity, and their use is extremely limited to sportswear, etc., and is not suitable for casual wear or summer women's wear. be.

Therefore, the first object of the present invention is to form a permanent embossed pattern on a thin fabric with a coarse warp and weft density.

A second object of the present invention is to efficiently obtain a fabric with a complicated grain pattern.

A third object of the present invention is to obtain a novel textured fabric in which a textured surface and a flat surface are front and back.

[Structure of the invention]

The wrinkled fabric according to the present invention has a fabric weight of 200 g/m ² or less of fabric A with low shrinkage rate, and fabric A with low shrinkage rate and fabric B with high shrinkage rate, where the difference in shrinkage rate X is 3% or more. two pieces of fabric with adhesive application area occupancy Y
0.0005~4%, adhesive application area S 0.0003~
0.04cm ² , and the distance R between adhesive application parts is 0.3 to 5.0cm.
Value R/S obtained by dividing the distance R by the area S of the adhesive application area
is 10 or more, and then the fabric B with a high shrinkage rate is subjected to a treatment that causes shrinkage, and the fabric A with a low shrinkage rate is raised. This is a characteristic feature.

This shrinkage rate difference means the difference between the shrinkage rate of Fabric A and the shrinkage rate of Fabric B in either or both of the vertical and horizontal directions, and does not necessarily mean the difference in the shrinkage rates in both the vertical and horizontal directions; it is the thermal shrinkage rate, Any shrinkage rate such as water shrinkage rate or other shrinkage rate due to a chemical solution may be used. That is, it must be a difference in shrinkage rates measured under the same processing conditions, and the difference between the heat shrinkage rate of fabric A and the water shrinkage rate of fabric B does not correspond to the shrinkage rate difference referred to herein. However, it is recommended to use fabric A with a low shrinkage rate and fabric B with a high shrinkage rate such that the difference in washing shrinkage rate is 3% or more. Here, the washing shrinkage rate is JIS-L-1042 (F-1 method)
This refers to the shrinkage rate of a fabric measured after washing and drying the fabric.In the present invention, it is required that the difference in the washing shrinkage rate between Fabric A and Fabric B be 3% or more. In order to ensure such a difference in shrinkage rate between fabrics A and B before lamination, a method may be used in which one fabric A or B is stretched by 3% or more in one or both of the vertical and horizontal directions and then set as is.

The raw fabric used may be a woven fabric, a knitted fabric, or a non-woven fabric, but the purpose of the present invention is better served by using a woven fabric as one of the fabrics with a low shrinkage rate.

Adjust the viscosity of the adhesive to 20,000 c.ps or more, preferably about 25,000 c.ps, without foaming, and apply it to a thickness of 50 to 300 μm by printing or stamping on one or both of fabrics A and B in the form of dots. The two fabrics are overlapped and dried under pressure using a cylinder roll, etc., and bonded together.

Here, dotted line means that the adhesive is applied in a finely distributed manner when looking at the entire fabric macroscopically, and if the area of the unit application area is 0.0003 to 0.04 ^cm2 , When looking at the unit application area of adhesive, the stamped outline of the unit application area does not necessarily have to be circular or oval, but may be star-shaped, cross-shaped, linear, grid (#)-shaped, etc. It's okay.

In addition, in the present invention, the area of the adhesive application part is
Refers to the area covered by adhesive in a fine circle, oval, line, star, cross, grid (#) shape, etc. drawn at a point where adhesive is applied, and
Adhesive application area occupancy means the proportion of the fabric surface occupied by adhesive application areas distributed over the entire surface of the fabric, and adhesive application area spacing is the distance between adjacent application areas. means.

〔Effect of the invention〕

Fabrics bonded together using the well-known bonding method are made with the aim of improving the physical properties of two raw fabrics by complementing each other's defects, so the adhesive is applied to the entire surface of the two raw fabrics. It is applied so that it adheres to a non-separable body, and if the shrinkage rates of the two raw fabrics that are pasted differ, the difference in shrinkage causes the pasted fabric to warp in a "surume" pattern. Since it returns and rolls up, it does not serve the intended purpose. However, in the present invention, the fabrics A and B are not bonded over the entire surface, but have an adhesive application area occupancy Y of 0.0005 to 4% and an adhesive application area S.
0.0003~ ^0.04cm2 , adhesive application part interval R is 0.3~5.0
cm, and the value R/S obtained by dividing the distance R by the area S of the adhesive application area is bonded with a line point of 10 or more, so when shrinkage treatment is performed, the low shrinkage fabric becomes a unit There is no warping phenomenon that causes bumps between coated areas to form a grained pattern. However, in this case, if the low-shrinkage fabric is hard and thick, wrinkles and bulges will not occur, and the fabric will warp as it is pulled up by the high-shrinkage fabric, or the fabric surface will be damaged at the adhesive application area. A shear stress parallel to the two fabrics acts, causing separation between the two fabrics. For this reason, use a thin, flexible fabric with a basis weight of 200 g/m ² or less, preferably 100 g/m ² or less, as a low-shrinkage fabric.
It is important to prevent such peeling between the fabrics. In addition, even if the area of the unit coating part is 0.0003 to ^0.04cm2 and the interval between the unit coating parts is 0.3 to 10cm, if the value obtained by dividing the interval by the area of the adhesive coating part is smaller than 10, for example, the unit coating part If the area of the applied area is 0.04cm ² and the interval between unit applied areas is 0.3cm, and the value obtained by dividing the area of the applied area by the interval between the applied areas is 7.5, a "surume"-like warpage will appear on the applied area. The applied area becomes fine and noticeable, and this tendency is also seen throughout the fabric, so in order to make the adhesive applied area inconspicuous, the area occupied by the adhesive should be 4% or less, and the unit coating rate should be set to 4% or less. The wearing area is
It is important that the distance is 0.04 cm ² or less, and that the value obtained by dividing the distance by the area of the adhesive application area is 10 or more.

The embossed fabric obtained in this way has a bag-like shape between fabrics A and B, which provides heat retention, while the adhesive is not applied to the entire surface in the form of a film, so it has appropriate breathability. In particular, the internal voids formed by the raised grains act as a pump, so that a fabric with good perspiration properties can be obtained. Best of all, since the low-shrinkage fibers and high-shrinkage fibers that make up the fabric are joined by adhesive rather than by a knitting structure, it is possible to change the part of the fabric by changing the bonding points at will. As a result, it is possible to draw abstract designs at any time instead of the plain color like conventional ones, and the manufacturing equipment includes commonly used knitting and looms, adhesive printing equipment, dyeing and finishing equipment, etc. Since the present invention can be used as is, it is easy to implement the present invention in terms of equipment, and if the fabric weight and shrinkage rate difference meet the requirements of the present invention, various existing fabrics can be used as the raw fabric to be processed, depending on the purpose and fashion. We can produce small lots of a wide variety of embossed fabrics to suit your needs.

In addition, fabrics A and B, which are double woven fabrics, are the raw material.
are joined by adhesive rather than by warp or weft yarns that are likely to shift or come off, so even if these fabrics A and B are coarse and low density, low shrinkage fabrics can be coated in units. Therefore, according to the present invention, it is possible to obtain a so-called see-through embossed fabric with a rough texture, low density, and transparency. An opal pattern or the like is applied, or fabrics with different water repellency or moisture absorption properties are used for the raw fabrics A and B, or the combination of raw fabrics A and B is made into a woven fabric and a knitted fabric. By changing between woven fabrics and non-woven fabrics, knitted fabrics and non-woven fabrics, low-density woven fabrics and high-density woven fabrics, etc., it is possible to obtain clothing with an even more elegant three-dimensional feel that is extremely varied in appearance, texture, physical properties, etc. Become.

In particular, if the difference in shrinkage rate between the original fabrics A and B is due to the shrinkage rate after washing, the embossed pattern that is formed will be semi-permanent because it will appear clearly every time it is washed.

As is clear, the present invention efficiently produces a new fabric that has appropriate heat retention, sweat perspiration, and breathability, and has a semi-permanent grain pattern that is smooth on one side and has a complex three-dimensional effect on the other side. The advantages of the present invention are considerable, as it can be obtained economically and economically.

Incidentally, the raised grain pattern may be pressed with a press roller or the like and changed into a wrinkle pattern set in a ripple pattern in the pressing direction, and such embodiments are also included within the scope of the present invention.
