Problems solved by technology

[0003] Due to the structural characteristics of polyester, disperse dyes are easy to dye spandex, and it is also easy to resolve, so it will reduce the color fastness
The dispersion solubility of disperse dyes in a certain bath ratio is limited. With the increase of disperse dyes, the dyeing rate of disperse dyes decreases, and the utilization rate of disperse dyes decreases. How to improve the utilization rate of dyes, dyeing fastness, stability, weight Reality and cost reduction have become the primary problems to be solved in the dyeing industry

Abstract

The invention discloses a polyester two-way-stretch fabric dyeing process including the steps of pretreatment, preshaping, dyeing, dehydration, drying, scotching and shaping to obtain a dyed polyestertwo-way-stretch fabric. In the method, under a low bath ratio condition, a dispersed dye is used for dyeing the fabric in two stages in a heat insulation manner, then the temperature is slowly decreased, sewage is discharged and the fabric is cleaned in clear water. The process is used for dyeing the polyester two-way-stretch fabric, is high in dyeing rate and good in color fastness, can reduce folds, shorten operation time and save energy, and can reduce cost.

Description

technical field [0001] The invention relates to the technical field of fabric finishing and dyeing, in particular to a polyester four-way elastic cloth dyeing process. Background technique [0002] The main components of polyester four-way stretch fabric are polyester and spandex. Polyester four-way stretch is an important variety of synthetic fibers. It is made of pure terephthalic acid or dimethyl terephthalate and ethylene glycol through esterification or Polyethylene terephthalate, a fiber-forming high polymer produced by transesterification and polycondensation, is a fiber made by spinning and post-processing. The characteristics of polyester four-way stretch fabric: high strength, good elasticity, good heat resistance, smooth surface of polyester, good wear resistance. Abrasion resistance is second only to nylon with the best abrasion resistance, better than other natural fibers and synthetic fibers, good light resistance, corrosion resistance, and has great market de...
