Abstract

The invention provides a preparation method of nanoscale liquid dispersion dye. The nanoscale liquid dispersion dye is prepared from following raw materials in parts by weight: 10-20 parts of nanoscale dispersion dye, 5-7 parts of a dispersion agent, 20-30 parts of ethanol, 3-5 parts of a deforming agent, 8-10 parts of starch, 5-7 parts of sodium chloride, 3-5 parts of sodium carbonate and 10-20 parts of deionized water. According to the preparation method of the nanoscale liquid dispersion dye, the particle size of the nanoscale liquid dispersion dye is small, after common printing, a textiledoes not contain azo dye which can decompose into carcinogenic aromatic amine, and does not contain carcinogenic dye, sensitizing dye, forbidden aromatic amine and a biological active substance, andthe heavy metal content meets permissible limits; and after the nanoscale liquid dispersion dye applied to textile, the fixation rate is high, low-color-degree waste water is reused, and the waste water discharge can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of dyes, in particular to a nanoscale 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 for the dyeing of acetate fiber, known as acetate dye. 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. Therefore, new requirements are put forward for dyes, that is, dyes with better hydrophobicity, certain dispersibility and sublimation resistance are required. At present, the disperse dyes used for dyeing polyester fabrics in printing and dyeing processing basically have these properties, but due to the variety There...
