Textile chitosan coating additive with color gradual changeability along with time passing and preparation method thereof

Abstract

The invention discloses a textile chitosan coating additive with color gradual changeability along with time passing and a preparation method thereof. The composition comprises, by weight, 140-180 parts of high-molecular chitosan, 140-180 parts of chitosan fibers, 3-5 parts of sodium alginate, 4-5 parts of ethylene diamine tetra(methylene phosphonic acid), 4-5 parts of hyaluronic acid, 5-6 parts of a pigment 1, 5-6 parts of a pigment 2, 0.1-0.3 parts of nanometer TiO2, 3-5 parts of a TPP ion cross-linking agent, 2-3 parts of a hydrophobic essence material, 1-2 parts of alpha-oxoglutarate and a proper amount of water. Different chitosans coat different pigments and the coated product is used as a textile dye additive. Chitosan is degraded along with time passing and the textile color is gradually changed so that the dual purposes are realized and textile color diversity and durability are realized.

Description

technical field [0001] The invention belongs to the field of textile dye additives, and in particular relates to a chitosan-coated textile additive with the property of gradual color change over time and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, people's awareness of beauty is getting stronger and stronger, and clothing has become a basic project for people's face; in order to meet people's needs for clothing and clothing, clothing designs are full of everything, and the textile dye industry is also emerging with various technologies. Endless. Providing functional textiles to meet people's needs for clothing is a direction for the development of the textile industry. [0003] As a natural macromolecular polysaccharide, chitosan has a wide range of sources, non-toxic, odorless, good biocompatibility, biodegradation and good antibacterial properties, and its degradation products are non-toxic; in chitosan mo...

Problems solved by technology

[0003] As a natural macromolecular polysaccharide, chitosan has a wide range of sources, non-toxic, odorless, good biocompatibility, biodegradation and good antibacterial properties, and its degradation products are non-toxic; in chitosan molecules There are a large number of free amino acids in the structure, which is a rare positively charged polymer compound in natural polysaccharides. It can be used to coat various functional substances and then used in textiles to increase textiles such as photosensitivity, aroma, and therapeutic effects. function, however, so far, the design of chitosan-based coating is limited to the coating of a single dye, and there are relatively few studies on the color-changing coating loaded with multiple dyes, which limits the development of textiles to a certain extent.
