Warp knitting dyeing and finishing process

Abstract

The invention discloses a warp knitting dyeing and finishing process, and belongs to the technical field of dyeing and finishing processes. S2, blank inspection; s3, desizing is carried out; s4, washing with water; s5, dyeing: adding a leveling agent in a dye bath, and controlling the pH value of the dye bath by using an organic acid-releasing agent to optimize the dyeing process; s6, dehydrating; s7, flame-retardant shaping; s8, napping: controlling the wool height of the cloth according to the production requirement of a product; in order to improve the appearance quality and the product applicability, the hand feeling of the fabric is adjusted, the calendering face of the fabric is smoother, and gaps between fabric fibers are reduced; the grade of the product is further improved, the additional value is increased, certain smoothness is kept, and the protrusions on the surface of the fabric are sheared; according to the warp knitting dyeing and finishing process, preconditions are provided for uniformly and flatly rolling the chinlon warp knitting cloth onto a warp beam, meanwhile, overlarge cloth width shrinkage of chinlon fiber can be avoided, and the dyeing effect is improved.

Description

technical field [0001] The invention belongs to the technical field of dyeing and finishing technology, and in particular relates to a warp knitting dyeing and finishing technology. Background technique [0002] The weaving process includes weaving (also known as woven), knitting, weaving and non-woven, and knitting is divided into warp knitting and weft knitting. Warp knitting is a textile process belonging to the field of knitting. One or several groups of yarns arranged in parallel are formed into loops at the same time on all the working needles of the warp feeding machine to form knitted fabrics. This method is called warp knitting, and the formed knitted fabrics are called warp knitted fabrics. [0003] In the prior art, the dyeing and finishing process of warp-knitted fabrics is very mature, but there are still some deficiencies: the first is to make the yarn lint-free when weaving, so the yarn before weaving is starched, so Before dyeing, the size should be desized...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the dyeing and finishing process of warp-knitted fabrics is very mature, but there are still some deficiencies: the first is to make the yarn lint-free when weaving, so the yarn before weaving is starched, so Desizing should be done before dyeing to facilitate coloring. The dyeing of fabrics in the dyeing and finishing process lacks standardization, which leads to color difference and poor dyeing effect due to different temperatures during the dyeing process.
