One-step desizing pretreatment process for modified fiber fabric

Abstract

The invention discloses a one-step desizing pretreatment process for a modified fiber fabric. The one-step desizing pretreatment process comprises the following steps: (1) acceptance and inspection ofraw materials; (2) pretreatment of the raw materials; (3) yarn stabilizing treatment; (4) drawing-in; (5) yarn changing and weaving; (6) preparation of grey cloth; (7) singeing; (8) oil removal of greige cloth; (9) desizing. The one-step desizing pretreatment process is characterized in that firstly, singeing equipment is provided, so that fly yarns on the surface of the fabric can be singed rapidly and fully through metal blades of the singeing equipment; meanwhile, the metal blades can also guarantee surface flatness and smoothness of the fabric during and after singeing, and complete singeing can be achieved while the metal blades pass through the fabric surface; secondly, a tension-free placing device is designed in an oil removing process, and the fabric can be in a completely loosestate in the oil removing process through the tension-free placing device, so that the gram weights of the fabric can keep consistent at left, middle and right positions, as well as the head, middle and tail positions, and the fabric can move smoothly in order in the oil removing process.

Description

technical field [0001] The invention relates to a pre-treatment process for one-step desizing of modified fiber fabrics. Background technique [0002] Modified fiber fabrics are woven through unique knitting technology. The printing and dyeing process in the prior art is quite mature, but there are still some defects in the actual operation process, which leads to not only increased printing and dyeing costs, low printing and dyeing efficiency, but also It may have a relatively large impact on the environment. For example, singeing operation in the printing and dyeing process. In the actual operation process, the singeing operation mainly uses a high-temperature flame or rubbing the red-hot metal surface for singeing, and rapid burning at high temperature. wool, so as to achieve the purpose of burning and singeing without operating and damaging the fabric, but the existing singeing is not reasonable enough in the transmission structure of the fabric during the high-temperatu...

AI Technical Summary

Problems solved by technology

[0003] In view of the above existing problems, the present invention aims to provide a one-step desizing pretreatment process for modified fiber fabrics. The printing and dyeing process of the present invention can solve the above-mentioned problems of incomplete singeing and poor degreasing effect, and can improve the one-step desizing process. The treatment effect of the treatment process provides the basis for the subsequent printing and dyeing process, so that the quality of printing and dyeing is also improved simultaneously
