Abstract

The invention provides a disperse red dye composition, which mainly comprises one or more of component A with structure shown as a formula (I) and one or more of component B with structure shown as a formula (II). Based on the component A and the component B, the component A accounts for 40 to 99 percent by weight, and the component B accounts for 1 to 60 percent by weight. When the disperse red dye composition is used for dyeing a hydrophobic fiber material, residual dyeing fluid is clear and has small flooding. By regulating the proportion among different compositions, a red fabric with bright color, good thermal migration resistance and prominent washing fastness can be obtained, in particular, higher washing fastness can still be ensured after high-temperature setting, and the problemthat the washing fastness of the conventional disperse red dye is greatly reduced after high temperature finishing is effectively solved. The disperse red dye composition is suitable for dyeing medium-high fabrics, such as superfine fabrics, polyester / cotton, polyester / ammonia and other blending fabrics.

Description

(1) Technical field

[0001] The present invention relates to a disperse red dye composition applicable to dyeing hydrophobic fiber materials. (2) Background technology

[0002] In recent years, polyester fiber fabrics such as sportswear, casual clothes, automotive interior fabrics, etc. are dyed with disperse dyes to ensure that the finished product size is consistent and stable. Because the heat setting temperature is generally high, exceeding 140 ° C, the inside of the fiber The disperse dyes will undergo thermal migration in the opposite direction to that during dyeing, and part of the dyes will re-migrate to the surface of the fiber, resulting in a significant decrease in the washing fastness of the heat-set fabric after dyeing (generally only about 3 levels), and contaminate adjacent stickers. Lining or polluting the environment, and the existing washing fastness of disperse dyes are the data of polyester fabric dyed with disperse dyes after reduction cleaning but no hea...
