Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. First of all, it should be noted that in the drawings, the same components or parts denote the same reference numerals as much as possible. In describing the present invention, detailed descriptions of related well-known functions or configurations are omitted in order not to obscure the subject matter of the present invention.

As used herein, the terms "about", "substantially", and the like, are used at, or in close proximity to, numerical values as are indicative of preparation and material tolerances inherent in the meanings mentioned, and are intended to be accurate or to facilitate understanding of the invention. Absolute figures are used to prevent unfair use by unscrupulous infringers.

The term "fabric" is used herein to mean all of the convened textiles, knits, felts, plates, nonwovens, adhesives, and mold fabrics. However, in describing an embodiment of the present invention, a narrow woven fabric is described as an example.

Manufacturing method according to a preferred embodiment of the present invention can proceed to the yarn configuration step (S100), weaving step (S200), processing step (S300), post-processing step (S400).

First, in the yarn forming step (S100), the yarn is used polyester or polyester / rayon blend dyeing yarn for warp yarn, rayon dyeing yarn and three times the number of covered yarn is used for the weft yarn, the covered yarn is rayon dyeing yarn It is preferable that it is fine fineness.

The reason mentioned above is that the covered yarn is used for imparting elasticity, and rayon is much smoother in touch. Therefore, when weaving with rayon dyeing yarn having excellent touch, the thinner the thickness of the fabric is, the thinner the thickness of the fabric can be exhibited along with the excellent touch.

Said rayon ray dye is used as it is single yarn, it is preferable that it is 50 to 200 denier. If less than 50 denier it is too thin during weaving may significantly reduce the durability, if more than 200 denier there is a fear that the beautiful gloss properties are reduced.

In addition, the rayon ray dye yarn is mainly used rayon filament yarn yarn or yarn yarn, but the yarn yarn is available in a lead-free state, but the yarn yarn is dyed in a yarn state after being twisted for ease of yarn dyeing.

The original yarn is colored by adding a colorant to a spinning solution of a polymer having fiber-forming ability, and originally referred to coloring by adding a coloring agent to a spinning solution of viscose rayon or acetate. It is called the concept including also the case of synthetic fiber, such as polyester and a polypropylene. The additive is mainly used carbon black a lot.

The woven fabric obtained by the above-described salts is characterized by being able to obtain a woven fabric having a high-quality feel and fashion because the color is formed by different colors of fibers. The dyeing method is a method of dyeing with a thread or a method of dyeing with a cheese roll. However, in view of the economic efficiency of dyeing, the latter is the mainstream.

On the other hand, the covered yarn is prepared by covering 10 to 90 denier pre-dyed yarn and 20 to 60 denier spandex yarn with 250 to 350% draft ratio.

The pre-dyed yarn may be used a dye that is achromatic and chromophoric color depending on the color of the rayon pre-dyed yarn, and may include a primary yarn or a four-shot yarn such as nylon, polyester, acrylic.

After the yarn is composed of the rayon ombre yarn and the covered yarn, weaving the plain or twill weaving, the tissue during weaving proceeds the weaving step (S200) by weaving the rayon yarn in the tissue entering the covered yarn according to the arrangement of the two yarns. Therefore, it is preferable that the number of covered yarns, which are three times, are concealed by other yarns and woven with minimal exposure to the fabric surface.

Although the dough passed through the weaving step (S200) has little elasticity, but after the processing step (S300), the elasticity occurs due to the shrinkage of the covered yarn and rayon yarn dyed yarn, the degree of stretch depends on the arrangement of the covered yarn.

The above processing step (S300) includes the following processes, first, to remove the warp squeeze added in the weaving preparation process, to improve the appearance by removing the natural or additional impurities, and not to cause any disturbance in subsequent processes In order to perform the refining process in a continuous refiner (a refining step), the fabric is relaxed by using a net dry or a continuous tumbler that can artificially and gently process the flexibility of the fiber to dry the extruded fabrics without tension. step). The relaxed fabric is heat set at 170 to 200 ° C. to fix the resin and give it shrinkage (heat fix step).

After washing to the heat-set fabric to reduce the stretch and stretch the fabric through the post-processing step (S400) to prevent shrinkage and stretch, having a stretch to improve the shrinkage, and complete the fabric showing a smooth touch and elegant luster.

Fabrics manufactured through the above steps can be used for men's pants and jackets as well as women's jackets and suits, and can feel comfortable and comfortable to wear with an elegant luster and soft.

An embodiment according to a preferred embodiment of the present invention is as follows.
