Abstract

The invention discloses a reduced brown BR liquid dye and a manufacturing process thereof. The formula comprises: 1,4 aminoanthraquinone, 1-chloroanthraquinone, copper chloride, the mass percentage content of each component is: 1,4 aminoanthraquinone 17-20%, 1-chloroanthraquinone 18-23%, sodium fluoride 1-3%, aluminum trichloride 2-5%, dispersant 0.1-1%, water 48-55%, soda 1-2%, copper chloride 1-2%. According to the invention, 1,4 aminoanthraquinone, 1-chloroanthraquinone, sodium fluoride, aluminum trichloride, dispersant, anti-coagulation additive, water, soda and copper chloride in a specific ratio, and at the same time raw material selection and weighing are performed; finished product preparation and grinding are performed; filtration; dyeing analysis; packaging and warehousing are performed to enable the prepared liquid dye to be clean and environment-friendly, reduce dust pollution, reduce COD value in sewage when used in a printing and dyeing factory, save energy during production, have brighter color light than powder dye, and the reduced brown BR liquid dye is more convenient to use, and is truly environment-friendly dye; and has high strength and good plasticity.

Description

technical field [0001] The invention relates to the technical field of dye production, in particular to a vat brown BR liquid dye and a production process. Background technique [0002] Vat dyes are a class of high-grade dyes with many varieties, bright colors and excellent fastness. Due to their excellent light fastness, weather resistance, heat resistance, solvent resistance and wash resistance, vat dyes can be widely used in cotton, wool and silk. The printing and dyeing of cotton, linen, synthetic fibers and their blended fabrics and interwoven fabrics is a high-grade product in cotton dyes. Because vat dyes do not contain azo dyes that can be cracked under specific conditions to produce 23 carcinogenic aromatic amines, they are not allergic dyes, carcinogenic dyes and acute toxic dyes, do not contain environmental hormones, and the chromaticity of wastewater is low when used, it is An alternative to banned dyes. However, the existing vat brown BR dyes are usually powd...
