Abstract

The invention discloses an acid dye composition for nylon dyeing. The acid dye composition for nylon dyeing comprises a dye component and an auxiliary component. The acid dye composition is applicable to dyeing of nylon fabrics. The problems that metal complex dye has dark colored light in nylon fabric dyeing and other dyes have poor wet fastness are solved. The acid dye composition for nylon dyeing has high wet fastness and bright colored light and can meet requirements of medium- and high-grade clothing fabric products on quality specification.

Description

technical field [0001] The invention belongs to the technical field of dye development, and in particular relates to an acid dye composition used for nylon dyeing. Background technique [0002] The chemical composition of nylon is polyamide, with amino and carboxyl groups at the end of the molecule, and many amide groups in the molecular chain. In the acidic aqueous solution, the amino group and the carboxyl group are respectively in the state of -NH- and -COOH, so that the fiber can absorb the anion of the dye. Dyeing is mainly based on acid dyes dyed in weak acid dye baths. Nylon is a thermoplastic fiber, the dyeing rate is slow at low temperature, and the dyeing rate is faster when it is higher than 60°C. Appropriate surfactants can also be added to increase the leveling effect. Dyeing starts at about 40°C, gradually heats up to boiling, and boils for about 1 hour. After dyeing, tannin and tartaric acid can be used to fix the color successively to improve the washing f...
