Pretreatment process of chemical fiber fabric

Abstract

The invention discloses a pretreatment process of chemical fiber fabric. The process comprises the following operation steps of a, carrying out cloth turning and sewing on the chemical fiber fabric toobtain a product A; B, singeing the product A to obtain a product B; C, padding the product B in an enzyme solution, and performing thermal stacking at the stacking temperature of 55-65 DEG C to obtain a product C; and D, enabling the product C to be sequentially subjected to water washing in a water washing box, soaking in a working solution tank and steaming washing in a tight steaming box, enabling the speed of the tight steaming box to be 45-55m / min, the cloth containing amount to be 140-160m, and the steaming time to 2-4min, then enabling the product C to be subjected to water washing inthe water washing steaming box, and obtaining a finished product. The process has the characteristics that the technological process is shortened, the production efficiency is high, water can be saved, sewage discharge is reduced, and the product quality is improved.

Description

technical field [0001] The invention relates to a fabric treatment process, in particular to a pretreatment process for chemical fiber fabrics. Background technique [0002] With the improvement of living standards, people pay more and more attention to environmental protection and the negative impact of all walks of life on society. Synthetic and regenerated cellulose fibers and other chemical fiber fabrics are used in a large amount. The conventional pretreatment process currently used is a two-step process of turning over the seam, desizing, singeing, alkali-oxygen cold stacking and deoxidation bleaching. Water washing, not only the overall process is long, time-consuming and labor-intensive, the capacity of the steam box is small, the steaming time is short, and the effect is poor, resulting in reduced production efficiency and increased cost of the product, but also requires a large amount of alkali and water, which also leads to a large amount of generation of sewage....

AI Technical Summary

Problems solved by technology

Synthetic and regenerated cellulose fibers and other chemical fiber fabrics are used in a large amount. The conventional pretreatment process currently used is a two-step process of turning over the seam, desizing, singeing, alkali-oxygen cold stacking and deoxidation bleaching. Water washing, not only the overall process is long, time-consuming and labor-intensive, the capacity of the steam box is small, the steaming time is short, and the effect is poor, resulting in reduced production efficiency and increased cost of the product, but also requires a large amount of alkali and water, which also leads to a large amount of generation of sewage

[0003] In addition, the process also needs to be stacked on the track of the long car. For chemical fiber fabrics such as regenerated cellulose fabrics, scratches and horizontal stacking creases are easy to occur. Under the action of strong tension, the fabric will also have irregular abrasions, resulting in low quality and other products

[0004] Therefore, the existing chemical fiber fabric pretreatment process has the problems of long process flow, low production efficiency, large water consumption, large sewage discharge, and low product quality.
