Textile leveling aid

Abstract

A textile leveling aid is prepared from raw materials in parts by weight as follows: 6-11 parts of polyvinylpyrrolidone, 5-8 parts of isopropanol, 7-9 parts of ammonium dodecylbenzene sulfonate, 4-6 parts of ethylene glycol adipate, 6-10 parts of dicyclohexylmethane diisocyanate, 2-6 parts of a cross-linking agent, 3-8 parts of polyacrylamide, 1-5 parts of tetraacetylethylenediamine, 4-9 parts of sodium hydroxide, 6-11 parts of diglycol laurate, 4-10 parts of polyethylene amide, 2.5-8 parts of dimethyl siloxane, 0.2-1 part of acetone and 2-4 parts of a dispersing agent. The textile leveling aid has the benefits as follows: the textile leveling aid can have the very good leveling effect, prevents dye coagulation and has good temperature stability.

Description

technical field

[0001] The invention relates to a textile leveling auxiliary agent. Background technique

[0002] There are many methods of level dyeing, and their purpose is: 1. To distribute the dye molecules evenly on the surface of the fiber; 2. To diffuse the dye distributed on the surface of the fiber to the inside of the fiber. The above goals can be achieved by controlling the dyeing speed, controlling the uniform concentration and temperature of the dye bath, using dyes with good dye transfer properties, using dye transfer agents and carriers, and dyeing at high temperature for a long time. However, the performance of the existing leveling agents is not stable enough at different temperatures, and cannot well achieve the effect of dye uniformity, resulting in uneven printing and dyeing, and then resulting in unqualified printing and dyeing quality. Therefore, uniform printing and dyeing cloth has become a problem that needs to be solved urgently in the rapid develo...
