Abstract

The invention relates to a preparation method of a dye leveling agent, and belongs to the technical field of dye additives. Mixed enzymes and acrylamide are mixed for polymerization under the action of an initiator to form polyacrylamide, the enzymes are encapsulated, metal elements in mixed liquid are adsorbed, the enzyme activity is increased by using the metal elements, cross-linking with chitosan and mixed sugar is achieved under the action of an assistant, incomplete cross-linking is achieved under the action of N-methylenebisacrylamide and glutaraldehyde, and an acylating agent is used for acylation to increase active groups. When the dye leveling agent is in use, firstly the mixed enzymes increase surface active groups by partially destroying the surface of a fabric; then the dyeingagent is bonded with the surface of the fabric under the action of glutathione synthetase through an incompletely cross-linked material, and the adoption of fatty alcohol is more conductive to infiltration of raw materials; finally the dyeing agent is adsorbed on the surface of the fabric under the action of the formed polyacrylamide and loaded chitosan and is separated from the surface of the fabric with the increase of the temperature, and thus coloring can be better achieved.

Description

technical field [0001] The field relates to a preparation method of a dye leveling agent, which belongs to the technical field of dye additives. Background technique [0002] High-temperature leveling agent is mainly a dyeing auxiliary for polyester fabrics. The basic constituent of polyester is polyethylene terephthalate. From the molecular structure of polyester, it lacks active groups that can combine with fuel. Therefore Direct dyes such as acid dyes and reactive dyes cannot be used for dyeing, only water-insoluble disperse dyes can be used for dyeing. And because the polyester molecules are arranged relatively closely, there are only small gaps in the fiber, and it is difficult for the dye molecules to enter the interior of the fiber under low temperature conditions. The gaps allow the dye molecules to enter the interior of the fiber. Therefore, the dyeing of polyester fibers is carried out under high temperature conditions (120-130°C) with disperse dyes. [0003] Th...
