Abstract

The invention belongs to the technical field of dyeing auxiliary agents and discloses an efficient fabric carrier. A nano material is prepared from nano hydroxyapatite, sodium alginate and the like; positive ion groups are introduced in a reaction process by adding of 3-chloro-2-hydroxypropyl-trimethyl ammonium chloride and 2,3-glycidyl trimethyl ammonium chloride; gel generated directly or indirectly is used for storage of controlled-release dyes and other components to prolong action time, and by a regulation effect on internal charges, the dye uptake is increased, and the migration propertyis diminished; a polyurethane component is prepared from polyether glycol, dimethylol propionic acid, diethylene glycol and the like; a hydrophobic network is constructed by means of oxime bond self-repairing, ketone-hydrazine crosslinking and the like and used for improving washing resistance and keeping dye components. By the efficient fabric carrier, problems of low washing resistance and highmigration property of an existing common carrier are solved.

Description

technical field [0001] The invention relates to the technical field of dyeing auxiliaries, in particular to a high-efficiency fabric dyeing agent. Background technique [0002] Polyester is an important variety in synthetic fibers and is the trade name of polyester fibers. It is a fiber-forming high polymer prepared from terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (EG) through esterification or transesterification and polycondensation reactions—— Polyethylene terephthalate (PET), a fiber made by spinning and post-processing. From the perspective of polyester molecular composition, it is composed of short aliphatic hydrocarbon chains, ester groups, benzene rings, and terminal alcohol hydroxyl groups. In addition to the existence of two terminal alcohol hydroxyl groups in polyester seeds, there are no other polar groups, so the hydrophilicity of polyester fibers is extremely poor. Polyester molecules contain about 46% ester groups. The ester ...
