Compound type reactive dye formula

Abstract

The present invention relates to the field of dyes, specifically a composite reactive dye formulation, the parts by weight of each component are: 40-60 parts of triarylmethane dyes, 25-45 parts of nitro and nitroso dyes, α-bromo 20‑40 parts of acrylamide reactive dyes, 2‑10 parts of polymethine dyes, 1‑10 parts of sodium chloride, 2‑8 parts of disodium hydrogen phosphate, 10‑20 parts of sodium dihydrogen phosphate, 5 parts of sodium thiosulfate 15 parts, 1-20 parts of sodium carbonate, 5-15 parts of urea. The reactive dye of the invention is a dye with high fastness and wet fastness, bright color, excellent performance and strong applicability, and its hue and performance can meet the requirements of the market for fibers and clothing materials.

Description

technical field [0001] The invention relates to the field of dyes, in particular to a composite reactive dye formulation. 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 dye production. [...
