Dispersed black dye composition, dispersed black dye, and preparation method and application thereof

Abstract

The invention relates to a dispersed black dye composition, dispersed black dye, and a preparation method and application thereof. Based on the total weight of the dispersed black dye composition, the dispersed black dye composition comprises 5 to 15 weight percent of component A shown as a formula (I), 35 to 60 weight percent of component B shown as a formula (II), 20 to 35 weight percent of component C shown as a formula (III) and 5 to 15 weight percent of component D shown as a formula (IV). The dispersed black dye consists of the dispersed black dye composition and auxiliary materials, has high washing fastness and sublimation fastness and has low contamination property on polyester ammonia cotton and blended fabric thereof. R in the formula (I) is alkyl of C1-C2 and R2 in the formula (II) is Cl or Br.

Description

technical field [0001] The present invention relates to a kind of disperse black dye composition, disperse black dye and preparation method thereof, the present invention also relates to the purposes of disperse black dye composition and disperse black dye for fabric dyeing and / or printing aspect, with described disperse A textile obtained by dyeing and / or printing a black dye composition and a disperse black dye, and a textile product made using the textile. The disperse black dye is suitable for the dyeing and printing of polyester fibers, especially for the dyeing and printing of polyester-spandex, polyester-cotton and other blended fabrics. Background technique [0002] With the rapid development of polyester-spandex polyester-cotton and other blended fabrics, people have higher and higher requirements for the application performance of dyes, and excellent fastness is the basic performance required by customers. Then, general disperse dyes stain spandex and cotton heavi...

AI Technical Summary

Problems solved by technology

However, general disperse dyes stain spandex and cotton heavily, which cannot meet the needs of customers

At present, there is a great demand for disperse black in the market. The traditional disperse black WXF has been widely used, especially because of its good washing fastness and sublimation fastness. However, disperse black WXF is only suitable for polyester fibers. , Polyester-cotton fiber, the advantage of washing fastness is not obvious
