Problems solved by technology

[0005] The full name of butane tetracarboxylic acid is 1,2,3,4-butane tetracarboxylic acid, or BTCA for short. It is currently considered to be the polycarboxylic acid with the best wrinkle resistance. The finishing effect is better than DMDHEU, but because of its high price, it is usually several times that of DMDHEU, and the high usage in the finishing process can lead to high processing costs of finished fabrics, which is difficult to be accepted by the market. Butane tetracarboxylic acid As an anti-wrinkle finishing agent for textile fabrics, a catalyst is needed to promote the crosslinking. The price and dosage of sodium hypophosphite as a catalyst are also at a relatively high level, which further increases the cost of the finishing process. More importantly, waste after finishing The phosphorus compound in the liquid is relatively high, and the discharge into the water body causes serious environmental pollution, which has become an important factor restricting butane tetracarboxylic acid anti-wrinkle finishing agents

Abstract

The invention relates to the technical field of textile auxiliary agents, and discloses a 5,5-diphenyl-2,4-imidazolidinedione sodium salt compounding butanetetracarboxylic acid fabric anti-crease finish agent. The fabric anti-crease finish agent is prepared from mixing of the 5,5-diphenyl-2,4-imidazolidinedione sodium salt and the butanetetracarboxylic acid, and the adding weight ratio of the 5,5-diphenyl-2,4-imidazolidinedione sodium salt to the butanetetracarboxylic acid is 1 : 120-200. After mixing of 5,5-diphenyl-2,4-imidazolidinedione sodium salt and the butanetetracarboxylic acid, esterification crosslinking efficiency of the butanetetracarboxylic acid and a cellulose molecule can be obviously strengthened, usage amount of the butanetetracarboxylic acid is reduced, and industrial energy consumption is reduced; meanwhile, the 5,5-diphenyl-2,4-imidazolidinedione sodium salt further achieves an effect of a catalyst, use of a traditional catalyst sodium hypophosphite is reduced, pollution of industrial phosphorus wastewater to the water body is reduced, and thus the 5,5-diphenyl-2,4-imidazolidinedione sodium salt compounding butanetetracarboxylic acid fabric anti-crease finish agent has very high economic benefits and ecological benefits.

Description

[0001] Technical field: [0002] The invention relates to the technical field of textile auxiliaries, in particular to a fabric anti-wrinkle finishing agent of synergistic butane tetracarboxylic acid. [0003] Background technique: [0004] The main reason for the easy wrinkling of cellulose fiber fabrics is that when the fibers are deformed by external forces, the hydrogen bonds between the cellulose macromolecular chains or the structural units of the fibers are destroyed, and new hydrogen bonds are formed at new positions, making it difficult for the fibers Return to original shape during deformation. Regarding the principle of anti-wrinkle, the early theory of resin deposition believed that urea and formaldehyde treatment were baked under acidic conditions to generate resin deposition inside the fiber, thereby increasing fiber elasticity. However, the most widely accepted one is the cross-chain theory. This theory believes that anti-wrinkle finishing is to generate covale...
