Abstract

The invention provides a multifunctional chemical system used for scouring and bleaching cotton-polyester blended fabrics and dyeing polyester components in one bath. The multifunctional chemical system comprises one or more of the following components: fatty alcohol-polyoxyethylene ethers, hydroxyethyl butyl ethers, glycerin polyoxyethylene ether oleate, fatty alcohol sulfate, triphenylethylene phenol polyoxyethylene ethers, polyoxyethylene ether oleate, solubilizers and water. The chemical system can be absolutely used for scouring and bleaching cotton-polyester blended fabrics and dyeing polyester components in one bath and ensures that the obtained fabric products have excellent quality and styles; the polyester dyeing effect of the chemical system can reach the traditional process level; and meanwhile, the chemical system is simple and convenient, effective and environment-friendly, simplifies the dyeing and finishing processes, improves the production efficiency and conforms to the concept of energy conservation and emission reduction.

Description

technical field [0001] The invention relates to the field of preparation of textile printing and dyeing chemicals, in particular to a multifunctional chemical system for scouring, bleaching and polyester component dyeing of polyester-cotton blended fabrics in the same bath. Background technique [0002] Polyester-cotton or cotton-polyester fabrics are made by blending or interweaving polyester fibers and cotton fibers. Because there is oil agent on polyester fiber, lignin, pectin, wax and ash on cotton fiber, it must be removed by scouring and bleaching before normal dyeing can be carried out. [0003] The traditional processing technology is: gray cloth → scouring and bleaching → hot water, warm water washing acid neutralization → polyester component dyeing → reduction cleaning hot water, warm water washing → cotton component dyeing. Generally speaking, the scouring and bleaching of polyester-cotton blended fabrics is carried out under alkaline conditions, while the dyeing...
