A kind of disperse red dye composition, dye product and application thereof

Abstract

The invention relates to a disperse red dye composition, a dye product and application thereof. The disperse red dye composition is mainly composed of a component A and a component B, wherein the component A is selected from one or more of dye monomer compounds disclosed as a Formula (I), and the component B is selected from one or more of dye monomer compounds disclosed as Formula (II); and on the basis of the component A and component B, the mass percent of the component A is 30-95%, and the mass percent of the component B is 5-70%.In the Formula (I), R1 is hydrogen or C1-C4 alkyl group, R2 is hydrogen, C1-C4 alkyl group, hydroxyethyl group or -CH2COOC2H4OCH3; and in the Formula (II), R3 is hydrogen, C1-C4 alkyl group, -CH2CN or -CH2COOR5, wherein R5 is C1-C4 alkyl group, and n is 1 or 2. The disperse red dye product mainly contains the disperse red dye composition and assistants, wherein the weight ratio of the assistants to the disperse dye composition is (0.2-5):1.When being used for dyeing a hydrophobic fiber material, the dye product has excellent fastness to washing and excellent thermal migration resistance.

Description

(1) Technical field [0001] The present invention relates to a kind of dyestuff composition, dyestuff product and its application, especially relate to a kind of disperse red dyestuff composition, the dyestuff product made from this composition and this dyestuff product on hydrophobic fiber material especially polyester / ammonia blended Application in fabric dyeing. (2) Background technology [0002] Disperse red is one of the basic colors of commercial disperse dyes, which can be used alone or as an important component to create other bright colors. With the development of new synthetic fibers and polyester microfiber textile fabrics, especially the blended fabrics of polyester superfiber and spandex that are becoming more and more popular, although these conventional fabrics such as C.I. Disperse Red 54, C.I. Disperse Red 74, and C.I. Disperse dyes can also dye new fibers, but because the molecular attraction between dyes and fibers is greatly reduced, the most obvious is t...

AI Technical Summary

Problems solved by technology

With the development of new synthetic fibers and polyester microfiber textile fabrics, especially the blended fabrics of polyester superfiber and spandex that are becoming more and more popular, although such conventional fabrics as C.I. Disperse Red 54, C.I. Disperse Red 74, and C.I. Disperse Red 153 Disperse dyes can also dye new fibers, but because the molecular attraction between dyes and fibers is greatly reduced, the most obvious is that the dye uptake rate of dyes has dropped significantly, and the fastness of all aspects of the dyed fabrics has decreased to varying degrees. Especially the impact on the washing fastness is more obvious, therefore, the products with high washing fastness are urgently needed in the market to be applied to these new fiber fabrics
