Special high-temperature levelling agent for polyester fabric dyeing

Abstract

The invention discloses a special high-temperature levelling agent for polyester fabric dyeing and belongs to the technical field of fabric dyeing and finishing auxiliaries. The developed special high-temperature levelling agent for polyester fabric dyeing is prepared from polyimide resin, a dilute, polyallyl amine, N'-cetyl-N,N-dimethylethyl amidine, water, enzymolysis gelatin dispersion liquid,glycoprotein and a preservative. In the preparation process, the special high-temperature levelling agent for polyester fabric dyeing is prepared by the following steps of stirring and mixing the polyimide resin and the dilute firstly to obtain a polyimide diluent; and then sequentially adding the polyallyl amine, the N'-cetyl-N,N-dimethylethyl amidine, the enzymolysis gelatin dispersion liquid, the glycoprotein and the preservative into water, performing uniform stirring and mixing, then adding the polyimide diluent, then introducing carbon dioxide gas in a stirring state, and performing discharging and filling. The special high-temperature levelling agent for polyester fabric dyeing provided by the invention has excellent dyeing effect and colour fastness.

Description

technical field [0001] The invention discloses a special high-temperature leveling agent for polyester fabric dyeing, which belongs to the technical field of fabric dyeing and finishing auxiliaries. Background technique [0002] Polyester fiber is the most widely used synthetic fiber with the largest output. Due to the tight structure and strong hydrophobicity of the polyester polymer that makes up the polyester fiber, it cannot be dyed under normal pressure like other fibers, but must be dyed at high temperature with disperse dyes. In addition, in order to save resources and further improve labor productivity, the rapid dyeing method of polyester is often used, but rapid dyeing is often not easy to level dye, and it is necessary to add a leveling agent with excellent dispersibility to prevent the dye from agglomerating and have excellent dye migration. performance. The different physical forms of dyes have a great influence on their solubility in water and high-temperatur...
