Abstract

The invention discloses a preparation method of a textile finishing agent, and belongs to the field of chemical engineering. Carbomer dispersion liquid used as a thickener reacts with glycoprotein hydrolysate, and carbomer molecules can form hydrogen bonds together with a sugar residue on an oligosaccharide chain in a glycoprotein to generate a relatively strong mucus gel network structure achieving a thickening effect, so that the product stability is further improved; furthermore, the molecular structure of carbomer contains a large amount of carboxyl; after a part of the carboxy is neutralized, the carboxyl can be ionized; due to the mutual repulsion effect of negative charges, the carbomer molecules extend in a diffusing manner and is in an expanded state, so that physical crossing entanglement of a three-dimensional network structure in the system is realized; and meanwhile, the negative-charged carboxyl can shield positive charges in a part of the chitosan molecular structure toavoid excessive infiltration of a textile fiber, so that the bonding force is provided more stably, and the washability is improved. The preparation method solves the problem that the conventional textile finishing agent is low in antibacterial activity and washability at the present.

Description

technical field [0001] The invention belongs to the field of chemical industry, and in particular relates to a preparation method of a textile finishing agent. Background technique [0002] The functional finishing of textiles is a special finishing method that endows textiles with excellent properties such as use, safety, and appearance in order to meet certain special requirements for use of textiles. The functional finishing agent of textiles is a kind of product developed with the development of multidisciplinary technologies such as chemistry, biomedicine, polymer composite materials, photochemistry, thermodynamics, electricity, and ecology. Since the functional finishing of textiles is aimed at certain specific properties of textiles, it has strong purpose, good effect and high added value of the product. After functional finishing, textiles have a clear purpose and scope of use, and are also popular among consumers. According to statistics, the demand for functional...
