Problems solved by technology

Especially the fabrics processed with hydrophilic silicone oil, emulsified silicone oil, and polyester polyether softeners have poor sublimation fastness, and will drop by 1-2 grades after being set.
[0003] For dark fabrics such as pure cotton, viscose, linen, etc., because most of the reactive dyes dyed dark fabrics have poor wet rubbing fastness, especially after some softeners and pre-shrinking processing will reduce Wet rubbing fastness, it is difficult to solve the problem of wet rubbing fastness even after repeated repairs

Abstract

The invention relates to the field of textile dyeing of polyester and dark fabrics such as blended fabrics, pure cotton, adhesives and hemp, in particular to a softening agent capable of improving the sublimation fastness of a disperse dye and the wet friction fastness of a reactive dye. The softening agent is characterized by mainly comprising the following raw materials in percentage by weight: bi-ethyl palmitate based quaternary ammonium salt, triethanolamine fatty acid ester quaternary ammonium salt, chitosan, polyvinyl pyrrolidone, polyether modified silicone oil, ternary polymerization block silicon oil, collagen and purified water. Compared with the prior art, the softening agent has the advantages that the sublimation fastness of the disperse dye can be improved by 0.5 to 1 grade and the wet friction fastness of the reactive dye can be improved by 0.5 grade after the sizing of a dyed fabric; and simultaneously, the neatened fabric is endowed with elastic and exquisite handfeel, so that the fabric is high in pollution resistance, dust resistance, shrinkage resistance, pilling resistance and static electricity resistance.

Description

technical field [0001] The invention relates to the field of textile printing and dyeing of polyester and blended fabrics, pure cotton, viscose, linen and other dark fabrics, in particular to a softener for improving the sublimation fastness of disperse dyes and wet rubbing fastness of reactive dyes. Background technique [0002] With the continuous improvement of export textiles and domestic consumers' requirements for the quality and function of textile fabrics, the requirements for fabric sublimation fastness, washing fastness, wet rubbing fastness and other indicators are constantly increasing. For dark-colored polyester blended fabrics, disperse dyes are easy to sublime after dyeing, so that part of the disperse dyes will be transferred to the surface of the fabric with the high-temperature hot air drying of the setting machine, resulting in a decrease in the washing fastness of the finished product. stereotyped. Especially the fabrics processed with hydrophilic silico...
