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 blue in the market. Traditional disperse blue WXF and disperse blue EX-SF are widely used, especially because of their good washing fastness and sublimation fastness. However, disperse blue WXF and disperse blue EX-SF is only suitable for polyester fibers, and the advantages of washing fastness are not obvious for polyester-spandex and polyester-cotton fibers

Abstract

The invention relates to a dispersed blue dye composition, dispersed blue dye, and a preparation method and application thereof. Based on the total weight of the dispersed blue dye composition, the dispersed blue dye composition comprises 5 to 14 weight percent of component A shown as a formula (I), 50 to 80 weight percent of component B shown as a formula (II), 10 to 20 weight percent of component C shown as a formula (III), 5 to 14.5 weight percent of component D shown as a formula (IV) and 0 to 1.5 weight percent of component E shown as a formula (V). The dispersed blue dye consists of the dispersed blue 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. R1 is Cl or Br, R2 is Cl or Br, and R3 is alkyl of C1-C2.

Description

technical field [0001] The present invention relates to a kind of disperse blue dye composition, disperse blue dye and preparation method thereof, the present invention also relates to the purposes of disperse blue dye composition and disperse blue dye for fabric dyeing and / or printing, with described The textile fabric obtained by dyeing and / or printing the dye composition and the disperse blue dye and the textile product made by using the textile fabric. The disperse blue dye is suitable for dyeing and printing of polyester fiber, especially suitable for dyeing and printing of blended fabrics such as polyester spandex and polyester cotton. 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 heavily,...
