Abstract

The invention discloses an environment-friendly leveling agent for disperse dye and belongs to the technical field of application of textile assistants. The environment-friendly leveling agent for the disperse dye is prepared from, by weight, 0.01-0.02 part of dimethyl disulfide, 14-17 parts of octadecyl toluene sulfonate, 5-7 parts of 2-acrylamide-2-methylpropanesulfonic acid, 1-1.4 parts of sodium thiosulfate, 15-20 parts of fatty alcohol-polyoxyethylene ether and 90-120 parts of water. The prepared environment-friendly leveling agent for the disperse dye is low in price, convenient to use and high in ecological environment friendliness; good leveling performance and retarding performance are achieved, no decoloration performance is achieved, electrolyte resistance is good, and foamability is low; dyed fabric is pure and full, the hand feeling is good, and the environment-friendly leveling agent a novel environment-friendly leveling agent.

Description

Technical field: [0001] The invention relates to the technical field of application of textile auxiliaries, in particular to an environment-friendly leveling agent for disperse dyes. Background technique: [0002] Disperse dyes are a kind of non-ionic dyes with low water solubility. They were first used in the dyeing of acetate fibers and are called acetate dyes. With the development of synthetic fibers, nylon and polyester have appeared one after another, especially polyester, because of its high alignment, less fiber voids, and strong hydrophobicity, it is necessary to expand the fiber with a carrier or under high temperature and thermal melting, so that the dye can enter Fiber and dyed. Scattered dyes have a simple structure and are in a non-ionic state with extremely low solubility in water. In order to disperse the dyes well in the solution, in addition to grinding the dye particles to less than 2 μm, a large amount of dispersant must be added to make the dyes Suspens...
