Formula of reactive dye

Abstract

The invention relates to a formula of reactive dye, and belongs to the technical field of printing dye. The formula comprises the following constituents in parts by weight: 20 to 40 parts of 2,4-difluoro-5-chloropyrimidine dye, 30 to 50 parts of vinyl sulfone dye, 20 to 40 parts of alpha-bromo-acrylic amide dye, 1 to 8 parts of dye leveller peregal O, 1 to 10 parts of sodium sulfate, 1 to 10 parts of sodium chloride, 2 to 8 parts of disodium hydrogen phosphate, 10 to 20 parts of sodium dihydrogen phosphate, 5 to 15 parts of sodium hydroxide, 1 to 20 parts of sodium carbonate, and 5 to 15 parts of urea. The dye has relatively high fastness and wet fastness, bright color, excellent performance and high applicability, and both the color and the performance of the dye can meet the requirements on fiber and apparel fabric by the market.

Description

technical field [0001] The invention relates to a reactive dye formula, in particular to a reactive dye with high fastness and wet fastness, bright color, excellent performance, strong applicability, and its hue and performance can meet the requirements of the market for fibers and clothing materials , belongs to the technical field of printing and dyeing dyes. Background technique [0002] The annual water consumption of my country's textile industry exceeds 10 billion tons, and the wastewater discharge accounts for the sixth place among all industries in the country. Among them, the printing and dyeing industry discharges the most serious wastewater, 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.
