Description

Woven-like fabric and method for manufacturing thereof

The present invention relates to a consumption tank fabric and a manufacturing method thereof, and more particularly, to a consumption tank fabric and a manufacturing method thereof having excellent melange effect and touch.

In general, small-sized fabrics have a sense of volume, soft touch and color, and give a warm feeling, and are widely used in suits such as men's wear for autumn and winter.Reformed research on various yarns has been actively conducted in recent years. Efforts have been made to obtain fabrics with the same texture.

Specifically, synthetic fibers such as polyester and polyamide, which are widely used not only for clothing but also for industrial use and industrially important values due to excellent physical and chemical properties, have been used and studied. However, these synthetic fibers have a single distribution of single yarn fineness, and lack of bulkiness has a limitation in conveying the feeling of natural fibers. In addition, since the refractive index is large and the surface is smooth, the surface reflectance of the light is so large that the color development is very low, and even after fabrication of fabrics and knits, the surface is smooth and there is a limit in conveying the feeling of natural fibers.

In addition, research has been conducted to obtain a fabric having a wooly texture using a biaxial blended yarn fabric, in which a soft touch is expressed by a loop of low shrinking fibers generated by a difference in shrinkage ratio of two yarns. There was no way, and there was a limit to expressing the feeling of natural wool with this method.

Therefore, the present invention requires not only a soft touch like natural wool, but also a consumption tank fabric having excellent physical and chemical properties and a method of manufacturing the same.

As such, by satisfying the conditions (1) and (2), through the second step of the manufacturing method (wool-like) fabric of the present invention, the process passability during fabrication is improved, the durability of the fabric is improved Can be. If the strength is less than 1.3 g / denier and the elongation is less than 15.3%, the elasticity of the composite twisted yarn is weak and the process permeability may be reduced during weaving, and the fabric is hard after dyeing the fabric including the composite twisted yarn under high temperature and high pressure. There may be a problem, and the touch feeling of the fabric is significantly reduced, so that the feeling of wearing at the time of manufacturing into clothing and improper use as a garment may be reduced. In addition, if strength exceeds 2.1 g / denier and elongation exceeds 23.1%, the mechanical strength may be significantly reduced, and thus the performance of the weaving process may be remarkably degraded. There may be a problem that can be degraded.

On the other hand, the composite twisted yarn prepared through the first step of the manufacturing method (wool-like) fabric of the present invention may satisfy the following conditions (3) to (5).

It is to evaluate the shrinkage property and the stretch property, and the higher this value, the stronger the shrinkage property and the stretch property.

If the remaining shrinkage is less than 12.7%, it is difficult to manufacture the fabric due to remarkable trimming in the fabric manufacturing process, and even if manufactured, there may be a problem that the shrinkage of the fabric is large and hard after the high temperature dyeing process. On the other hand, if the residual shrinkage exceeds 19.1%, there may be a problem that the fabric becomes hard due to excessive shrinkage after the dyeing process after the fabric is manufactured due to excessive shrinkage of the yarn.

In addition, the composite twisted yarn prepared through the first step of the manufacturing method (wool-like fabric) of the present invention as the condition (4), the lysona shrinkage may satisfy 4.4 ~ 6.8%, preferably 5.04 ~ 6.16% may be satisfied, and more preferably 5.32-5.88%.

If the non-aqueous shrinkage is less than 3.8%, there may be a problem of elasticity of the yarn. If the non-aqueous shrinkage is higher than 5.8%, the yarn shrinks due to the high temperature and the fabric shrinks or the non-uniform shrinkage occurs at high temperature. There may be a problem that the fabric is hard and the touch feeling can be significantly reduced.
