preparation example Construction

[0022] The preparation method of the complex is:

[0023] (1) In parts by mass, take 190-195 parts of ethanol solution, 26-35 parts of polymethyl glutamate, 22-24 parts of ethylene glycol monomethyl ether, 10-15 parts of sodium methoxide, 3-9 parts Auxiliary, put into the reactor, stir and react at 90-95°C for 4-6 hours;

[0024] (2) After the reaction, collect the reaction mixture, mix the reactants and carry out rotary evaporation, recover ethanol, collect the residue, and ball mill the residue and chitosan at 500r / min for 30min according to the mass ratio of 9-12:4 , to collect the ball mill;

[0025] (3) In parts by weight, take 100-110 parts of water, 40-45 parts of ball mill, 10-15 parts of (1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride Salt), 10-13 parts of N-hydroxysuccinimide, 13-15 parts of diatomaceous earth, 4-6 parts of vinyltriethoxysilane, 1-3 parts of 4-dimethylaminopyridine;

[0026] (4) First put water, ball mill, 1-(3-dimethylaminopropyl)-3-...

Abstract

The invention relates to a textile oxygen bleaching stabilizer, belonging to the technical field of textile assistant. Through ethylene glycol monomethyl ether, polymethyl glutamate and the like, polyethylene glycol-grafted polyglutamic acid is formed under the catalytic action of generating titanium dioxide during hydrolysis of an assistant, so that the dispersity and caking property of the polyglutamic acid can be increased; through grafting with chitosan under the catalysis action of 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride and 4-dimethylaminopyridine, the adsorption performance is improved; finally through combining with diatomite under the action of triethoxyvinylsilane and the like, the adsorption and chelating performances of metal ions can be improved; by crosslinking with partial polymer to form a spatial reticular structure, the adsorption performance is increased, and the bleaching effect is enhanced; the added additive can be effectively combined with calcium ions to form a calcium soap, so that the decontamination effect on textiles can be improved, and the problems that the current non-silicone oxygen bleaching stabilizer is poor in stable adsorption capability and the whiteness of the bleached product is low can be solved.

Description

technical field [0001] The invention belongs to the technical field of textile auxiliaries, and in particular relates to a textile oxygen bleaching stabilizer. Background technique [0002] h 2 o 2 It is a classic chemical product. Hydrogen peroxide bleach is widely used in the bleaching process of cellulose fibers and other fibers because of its good stability, no corrosion of equipment, and no pollution. It is an excellent bleaching agent, and the product whiteness It has good stability and no pollution to the environment, so it is a promising bleaching agent. During the bleaching process, H 2 o 2 The decomposition of is often uncontrolled, resulting in H 2 o 2 There are problems such as poor whiteness, decrease in fiber strength, and holes in the bleached cloth. In order to decompose hydrogen peroxide evenly and effectively during the bleaching process and avoid severe damage to the fabric, a certain amount of stabilizer must be added to the bleaching solution, tha...
