Formula of reactive dye

Abstract

The invention provides a formula of a reactive dye. The formula of the reactive dye comprises, by weight, 20-40 parts of a cyclically fluorinated reactive dye, 30-50 parts of a vinyl sulfone dye, 20-40 parts of an alpha-bromoacrylamide reactive dye, 1-8 parts of a dye leveller peregal O, 1-10 parts of sodium sulfate, 1-10 parts of sodium chloride, 2-8 parts of disodium hydrogen phosphate, 10-20 parts of sodium dihydrogen phosphate, 5-15 parts of sodium hydroxide, 1-20 parts of sodium carbonate and 5-15 parts of urea. The reactive dye has the advantages of high fastness and wet fastness, bright color, excellent performances and strong applicability, the hue and the performances of the reactive dye can adapt to market requirements of the formula and uses of the reactive dye in fibers and clothes, and the dye has excellent fastness, especially color fastness to light, color fastness to chlorine and color fastness to perspiration, and also has very good lifting capacity level. The dye has good contact color fastness uniform tone after being washed, and the hue and the performances of the dye can adapt to market requirements on the fibers and the clothes.

Description

technical field [0001] The invention belongs to the technical field of printing and dyeing dyes, in particular to a formula of reactive dyes. Background technique [0002] The annual water consumption of my country's textile industry exceeds 10 billion tons, and the waste water discharge accounts for the sixth place among all industries in the country. Among them, the printing and dyeing industry discharges the most serious waste water, accounting for about 80%. The water consumption per unit weight of textiles is 2-3 times that of foreign countries. times. Most of the dyeing and finishing processes are carried out at relatively high temperature, which consumes a lot of energy, and the unit consumption is 3-5 times that of foreign countries. Energy saving and emission reduction is an important policy formulated by the state. How to implement energy saving and emission reduction is the common responsibility and mission of the two industries of textile printing and dyeing and ...
