Problems solved by technology

First of all, the yarn in the fabric is easily broken, causing the hem of the garment to crack and reduce its strength; secondly, the pumice remaining on the fabric irritates the skin and affects the comfort of wearing; Internal damage; In addition, the discarded waste liquid will also pollute the environment
[0004] With the traditional stone mill washing finishing method, there are many processes and a long time, and some chemical reagents (such as sodium hypochlorite) used have serious environmental pollution and consume a lot of energy.
At the same time, during the rubbing process between the pumice stone and the fabric, it is easy to produce lime dust, which is easy to remain in the pockets and sutures, pollute the fabric and make the color of the fabric dark, and the strong friction between the stone and the fabric will cause damage to the fabric. damage, and at the same time cause a certain degree of damage to the inside of the device
Therefore, the production efficiency of this method is low, and the production cost is relatively high.

Abstract

The invention relates to a biological enzyme finishing process for jean. The finishing process is mainly divided into three stages: the first stage is pre-washing and amylase desizing, the second stage is cellulose enzyme washing, and the third stage is detergent washing, clean water washing and drying. The technological processes are as follows: enzyme desizing, water washing, enzyme washing, enzyme inactivation, water washing, soft finish and drying. The biological enzyme finishing process for the jean has the benefits as follows: the jean finished with the process is bright and clean in surface, smooth and clear in line and has permanent fuzzing resistance and pilling resistance. Compared with a previous terrazzo washing process, the technological process is shortened, the production cost is reduced, and damage to a fabric, equipment and a human body is avoided.

Description

technical field [0001] The invention belongs to the technical field of textile dyeing and finishing, and in particular relates to a biological enzyme finishing process for denim. Background technique [0002] As an evergreen tree of the textile industry, denim is still prosperous after a hundred years of development, especially the denim with three-dimensional style after grinding is deeply favored by people. The unique style of denim has traditionally been achieved through stonewashing. The stone washing process of denim generally uses pumice impregnated with sodium hypochlorite or potassium permanganate and a small amount of stripping agent and detergent in a drum washing machine for grinding. The friction effect is mainly to make the fabric feel soft, the dyes fall off, and then form a three-dimensional sense of local edges and seams that are worn white. [0003] During the stone washing process, due to the friction of the pumice stone, it will cause damage to the fabri...
