Abstract

The invention discloses color paste for blending cotton chemical fiber dyeing. The color paste comprises 3 to 14% of disperse dyes, 0.6 to 1.7% of a surface active agent, 0.3 to 0.8% of a cosolvent, 0.7 to 1.2% of polyacrylate, 0.1 to 0.3% of modified starch TGS5-C, and the balance of deionized water. The surface active agent is formed through mixing of an anionic surfactant and a nonionic surfactant, the dye grain fineness is 0.7 to 1.5 micrometers, and the invention further discloses a blending cotton dyeing method. The blending cotton dyeing method comprises the steps of S1, color paste configuration, S2, pre-treatment, S3, cotton dyeing, S4, washing treatment, S5, chemical fiber dyeing and S6 drying. The color paste for blending cotton chemical fiber dyeing is applied into the blendingcotton dyeing method, the washing step is omitted, the dyeing machining efficiency is improved, meanwhile, the discharge amount of sewage can be reduced, and environment friendliness is achieved.

Description

technical field

[0001] The invention relates to the field of textile dyeing, in particular to a color paste for dyeing blended cotton chemical fibers and a method for dyeing blended cotton. Background technique

[0002] Blended cotton is a textile made by mixing cotton fiber and chemical fiber materials in a certain proportion. It mainly includes nylon cotton, acrylic cotton and polyester cotton. It has the characteristics of air permeability and good elasticity, and is widely used in middle and low-end clothing products. sewing. The chemical fiber in the blended cotton belongs to polyester fiber, which is a fiber with textile properties obtained by using natural polymer compounds and artificially synthesized polymer compounds as raw materials, through the preparation of spinning dope, spinning and post-treatment processes. Polyester fibers are usually dyed with disperse dyes, while cotton fibers are usually dyed with reactive, direct, and vat dyes. In order to ensure that ...
