Problems solved by technology

[0004] In addition, cotton fabric anti-wrinkle often uses amide-formaldehyde finishing agents and polycarboxylic acid finishing agents. Amide-formaldehyde finishing agents mainly use methylol to react with hydroxyl groups on cotton fibers, but in the process of production and consumption harmful substances such as formaldehyde
There are mainly three types of polycarboxylic acid finishing agents, one is BTCA (1,2,3,4-tetracarboxylic butane), which is expensive and the synthesis process is complicated; the other is CA (citric acid), which has only three carboxyl groups , the treatment effect is biased, and it is easy to generate unsaturated by-products, resulting in yellowing of the processed product; its three PMA-AC (polymaleic acid-acrylic acid), difficult to synthesize, and poor reaction stability

Abstract

The invention relates to a color-fixing anti-wrinkle finishing agent which is amphoteric water-soluble polymer; the molecular formula of the polymer is (A)x(B)y(C), wherein A refers to an anionic link, B refers to a nonionic link and B refers to a cationic link; x, y and z respectively refer to polymerization degrees of the anionic link, the nonionic link and the cationic link; the ratio of x to y to z is (10-50) to (0-30) to (50-90); the anionic link is derived from a monomer containing adjacent carboxylic acid groups; the nonionic link is derived from a nonionic monomer; the cationic link is derived from a monomer containing cationic quaternary ammonium groups. The invention also relates to a preparation method and application of the color-fixing anti-wrinkle finishing agent. The finishing agent is capable of effectively improving the wet rubbing fastness, the soaping fastness and wrinkle recovery angle (WRA) of the dyed material; the finishing agent is simple and convenient to synthesize, low in cost, good in storage stability, free of release of formaldehyde in the producing and using process, green and applicable to good color-fixation anti-wrinkle treatment on textiles such as colored cotton, hemp, regenerated cellulose and the like.

Description

technical field [0001] The invention belongs to the field of textile printing and dyeing, and in particular relates to a color-fixing anti-wrinkle finishing agent and a preparation method and application thereof. Background technique [0002] Color-fixing finishing and wrinkle-resistant finishing are conventional post-finishing processes for dyed cotton fabrics. Direct dyes and reactive dyes can be used for the dyeing of cellulose materials. They all belong to the category of anionic dyes, with complete color spectrum and low price. However, in the chemical structure of direct dyes, most of them have hydrophilic sulfonic acid groups and carboxylic acid groups, which are relatively hydrophilic, and are only combined with fibers through hydrogen bonds and van der Waals forces, so the wet fastness is low, and fading, The staining phenomenon is also very serious, and although reactive dyes can form covalent bonds with cotton fibers, many dyes and fiber bonds are not stable, are...
