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
The invention belongs to dyestuff development technique field, be specifically related to a kind of acid dye composition for nylon dyeing.
Background technology
The chemical constitution of polyamide fibre is polymeric amide, and molecular end has amino, carboxyl, has many amide group in molecular chain.In acidic aqueous solution, amino become respectively with carboxyl-NH-makes the negatively charged ion of fibers adsorption dyestuff with-COOH state.Dyeing be take the matching stain of acidulous dye bath dyeing as main.Polyamide fibre belongs to thermoplastic fibre, and low temperature dyeing rate is slow, very fast higher than 60 ℃ of left and right dyeing rates, also can add suitable tensio-active agent to increase even dyeing effect.Dyeing, since about 40 ℃, is warming up to and boils gradually, boils and dyes about 1 hour.After dying, tannin, tartrated antimony fixation treatment can be used in succession, to improve washing fastness.Polyamide fibre also available 1:2 type is acid containing mordant dye dyeing, and product has good light fastness.With weak acid dye dyeing, have good level-dyeing property, but washing fastness is poor, is only suitable for dyeing shallow, middle look.Nylon dyeing also can application of active dyestuff and some substantive dyestuff.
Because many dyestuffs are fine for the dyeing coloured light of polyamide fibre, but wet fastness is poor, although use metallized dye fastness good, but color is not bright-coloured, can not get the coloured light and the quality index that require, very difficult while particularly dying middle dark color, how to have and can adapt to medium-to-high grade Dyeing Polyamide Fibre, can have again various bright-coloured coloured light, and to have preferably wet fastness dyestuff be the problem to be solved in the present invention.The present invention therefore.
Summary of the invention
The object of the invention is to provide a kind of acid dye composition for nylon dyeing, solved in prior art the color that dyes when medium-to-high grade nylon fibre carries out middle deep colour dyeing not bright-coloured, wet fastness can not meet requirement, can not get the problems such as the coloured light that requires and quality index.
