Abstract

The invention provides anhydrous printing liquid disperse dye. The anhydrous printing liquid disperse dye comprises, by weight, 10-15 parts of superfine disperse dye, 3-5 parts of sodium dodecylbenzene sulfonate, 3-5 parts of seconary alkane sulphonate sodium, 6-8 parts of hydroxymethyl celluloses, 5-10 parts of sodium citrate, 3-5 parts of sodium hydroxide, 5-8 parts of urea, 3-5 parts of sodiumlignin sulfonate, 3-5 parts of sucrose ester and 20-30 parts of deionized water. The anhydrous printing liquid disperse dye has the advantages that the anhydrous printing liquid disperse dye has smallparticle sizes, and textile products do not contain azo dye, which can be decomposed to generate carcinogenic aromatic amine, after normal printing is carried out by the aid of the anhydrous printingliquid disperse dye; the anhydrous printing liquid disperse dye does not contain carcinogenic dye or allergenic dye or banned aromatic amine or bioactive substances, and the heavy metal content conforms to allowed limited quantities; the anhydrous printing liquid disperse dye is high in color fixing rate after being applied to the textile products, low-chromaticity sewage can be reused, and accordingly sewage discharge can be effectively reduced.

Description

Technical field [0001] The invention relates to the technical field of dyes, in particular to an anhydrous printing liquid disperse dye and a preparation method thereof. Background technique [0002] Disperse dyes are a class of non-ionic dyes with low water solubility. It was first used in the dyeing of acetate fiber, called acetate dye. With the development of synthetic fibers, nylon and polyester have appeared one after another, especially polyester. Due to the characteristics of high alignment, less fiber voids, and strong hydrophobicity, the fiber must be expanded with a carrier or under high temperature and heat so that the dye can enter. Fiber and dyed. Therefore, new requirements are put forward for dyes, that is, dyes with better hydrophobicity, a certain degree of dispersibility, and sublimation resistance are required. The disperse dyes used in the dyeing of polyester fabrics in the printing process basically have these properties, but due to the higher variety Many...
