Abstract

The plait fabric is produced by air interlacing a high shrinkage yarn of polyester 50denier/24 filament as a core yarn and a low shrinkage yarn of polyester 50denier/96 filament as a sheath yarn to make a different shrinkage composite yarn, weaving the composite yarn to obtain a fabric, dyeing the fabric in the alkaline dyeing solution regulated to be pH 9-12 with a sodium sulfate and a sodium carbonate at 110˜140deg. C for 30˜60min.

Description

Manufacturing method of wrinkled fabric

The present invention relates to a method for producing a pleated fabric which is free from dyeing unevenness and can be produced by a very simple process.

Currently, the textile industry is researching and developing with two big goals: emphasizing practical aspects and pursuing fashion.

In line with this trend, the fabric is wrinkled to enhance the feel and fashion of the fabric.

As a method of manufacturing such a pleated fabric has been known how to rinse the fabric in a conventional manner and then impregnate and dye the fabric by a separate wrinkle processing.

The method has a problem that it is difficult to control the process and the productivity is lowered because the process of imparting wrinkles and the dyeing process are separated.

In addition, since the process of imparting wrinkles is performed by a physical method using a roller or the like, it is difficult to artificially control the wrinkles formed, and dyeing is performed after the wrinkles are formed. The problem of becoming bad has arisen.

The present invention solves the problems as described above, characterized in that to form wrinkles at the same time in the dyeing process.

Hereinafter, the present invention will be described in detail.

The present invention is treated with a polyester high shrink yarn as a screening, and fabrics are made of a bi-shrink blended yarn with polyester low shrink yarn as a superfiber yarn, and then treated with an alkaline salt solution having a pH of 9 to 12 at a temperature of 1110 to 140 ° C. It is a method of producing a pleated fabric, characterized in that the dyeing process for 30 to 60 minutes.

The present invention is a method of forming the fabric by the heat treatment in the dyeing process after manufacturing the fabric as a two-shrink blended yarn, so that no additional wrinkle applying process as in the prior art can reduce the processing time and reduce the manufacturing cost have.

In addition, the present invention uses the shrinkage characteristic difference of the yarn in the dyeing process rather than the physical contact method by the roller or the like, so that it is possible to control the wrinkles given to the fabric according to the dyeing conditions and at the same time to reduce the shrinkage difference of the yarn As it is used, the wrinkles given to the fabric are uniform.

In addition, the present invention is to perform the wrinkles and dyeing at the same time in the dyeing process can solve the dyeing unevenness of the wrinkles, and since the pH of the salt solution is alkaline, the movement of the fabric is flexible to further improve the leveling effect.

In the present invention, when the pH of the saline solution is less than 9, the effect of softening the polyester fabric is insignificant and there is no leveling effect, and the effect of omitting the refining process does not occur.

In addition, when the pH exceeds 12, the alkalinity is so high that the fabric becomes brittle.

In addition, only when the dyeing conditions of the present invention are satisfied, wrinkles can be expressed to the maximum and dyeing unevenness can be prevented.

Example 1

A high shrink yarn of polyester 50 denier / 24 filaments and a low shrink yarn of polyester 50 denier / 96 filaments prepared according to a conventional method were entangled with air to produce a high shrink yarn mixed with a low shrink yarn at the core. .

Weaving was performed using the diaxial blended fiber as theodolite yarn.

The fabric structure was plain weave, 160 inclined / inch, 80 weft / inch weft, and the width of the fabric was 160cm.

The dough thus prepared was added to a liquid dyeing machine, and the dye was used CIDisperse Blue 56 1.0% (owf). The pH was adjusted to 11, 10 with sodium sulfate and sodium carbonate, and the temperature was raised to 130 ° C. for 45 minutes. Table 1 shows the appearance of the fabrics produced through the usual drying process.

[Examples 2-3 and Comparative Example 1]

Prepared in the same manner as in Example 1, but prepared by changing the pH of the salt solution as shown in Table 1.

Comparative Example 2

After fabricating the polyester 50 denier / 24 filament and the polyester 50 denier / 96 filament, respectively, and then weaved the yarn (not shrink), the fabric produced in the same manner as in Example 1 was relax-refined according to the conventional method After dehydration, dried and then buffing using sandpaper in emery mosquitoes.

Subsequently, the raising fabric was put into a rotary washer and treated at 120 ° C. for 30 minutes to impart wrinkles.

Next, 1.0% (o.w.f) of C.I.Disperse Blue 56 was used, 0.3 g / L of acetic acid was added, and the resultant was dyed in the same manner as in Example for drying in an acid salt solution.

The results of measuring the appearance are shown in Table 1.

TABLE 1

* Measurement of touch, wrinkle, and uniformity of dye is indicated by ○ if the test is good for 8 or more out of 10 people, △ if 5 or more are good for the test, and × for less than that.

* Process time is the time taken from weaving until dyeing and drying are completed.

Claims (1)

It is characterized by the fact that the fabric is made of bispun blended yarn with polyester high shrink yarn and polyester low shrink yarn as superfiber and then dyed at 110 ~ 140 ℃ for 30 ~ 60 minutes in salt solution with pH 9-12. Wrinkle fabric manufacturing method.
