Problems solved by technology

[0009] In addition, when performing mercerizing, the fabric feels very rough due to the rapid expansion only on the surface of the fiber. To overcome this shortcoming, it is necessary to use a large amount (concentration of more than 10%) of silicone softener. After the treated garment product is washed repeatedly, the silicone will peel off, resulting in a continuous deterioration of the handle and reduced dimensional stability

Embodiment Construction

[0033] Hereinafter, preferred embodiments of the present invention will be described in detail.

[0034] The inventor of the present invention found the following advantages and completed the present invention. The same as the mercerizing process with sodium hydroxide, when the fabric is processed by liquid ammonia, it can increase the luster of the fabric through expansion and tension, and improve the dimensional stability. Especially, thick fabrics such as denim can be processed quickly and uniformly. In addition, by using liquid ammonia to process the fabric, it can increase stretchability, increase strength, and improve shrinkage resistance.

[0035] The method for processing knitted fabrics and fabrics using liquid ammonia of the present invention includes the following steps:

[0036] The first step is to pre-treat the knitted fabric;

[0037] In the second step, the knitted fabric that has been pretreated in the first step is put into the liquid ammonia processing machine to ...

Abstract

The present invention relates to a knitted fabric processing method using liquid ammonia including: a first step in which a knitted fabric or a knitted work is pre-processed; a second step in which the pre-processed knitted fabric or knitted work is input into a liquid ammonia processing unit for liquid ammonia processing; a third step in which the liquid ammonia-processed fabric is allowed to pass through multiple heating rolls for ammonia evaporation; a fourth step in which the fabric evaporated in the third step is supplied to a team scrubbing unit for ammonia residue removal; and a fifth step in which the fabric is allowed to pass through a compactor for moisture removal after the fourth step.

Description

technical field [0001] The invention relates to a method for processing knitted fabrics by using liquid ammonia. More specifically, the present invention relates to a method of processing knitted fabrics with liquid ammonia, which is the same as the mercerizing process of treating with sodium hydroxide, which can increase the luster of the fabric and improve the dimensional stability through expansion and tension. In particular, thick fabrics such as denim can be processed quickly and evenly. Background technique [0002] Recently, the well-being and health sweeping the world have received high attention, and the casual wear and sportswear market that pursues mobility and convenience in the textile industry has developed rapidly. As a result, the consumption of knitwear, a core product in these markets, is growing beyond textile products. [0003] As consumers pay more and more attention to issues such as Well-being and health, the re-understanding of the environment has g...
