Problems solved by technology

At present, cationic modified polyester is more and more popular in the textile market, and it is more and more widely used in clothing fabrics; there are differences in the dyeing of cationic modified polyester and conventional polyester. Conventional polyester is dyed with disperse dyes under high temperature and pressure. Disperse dyes When dyeing polyester and nylon fabrics, there is a problem of disperse dyes staining nylon and spandex, which affects the color fastness of the fabric to washing

Abstract

The invention discloses a technology for dyeing and finishing improved terylene polyamide lycra fabrics. The technology comprises steps of oil-removing refining, pre-formalization, dyeing and finished product formalization. The technology for dyeing and finishing improved terylene polyamide lycra fabrics has the advantages of high-efficiency energy saving, emission reduction, cost reduction, and convenient operation. The technology for dyeing and finishing improved terylene polyamide lycra fabrics also increases breathable moisture absorption, antistatic property and anti-pilling performances of the fabrics.

Description

technical field [0001] The invention relates to a finishing process of textiles, in particular to an improved dyeing and finishing process of polyester nylon Lycra fabric. Background technique [0002] Cationic dyeable modified polyester is made by adding other monomers to the molecular chain of conventional polyester fiber by means of copolymerization, grafting, etc.; the structure of the modified polyester fiber becomes loose, and the flexibility of the molecular chain increases, which improves the quality of conventional polyester fiber. Excellent air permeability, hygroscopicity, static electricity and pilling properties, overcome the shortcomings of conventional polyester that is not easy to dye; at the same time, it reduces the staining of dyes on nylon fibers, improves easy cleaning and wet fastness, saves energy, and improves the color after dyeing. bright. At present, cationic modified polyester is more and more popular in the textile market, and it is more and mor...
