Problems solved by technology

Some dyes are directly included in the banned disperse dyes, and many conventional disperse dyes in the market cannot meet the latest environmental protection indicators in terms of chlorophenol, heavy metal content, banned aromatic amines, etc.
[0003] At present, the development of new structures of disperse dyes is less, and the main research work is on the compounding and synergism between dyes and dyes and auxiliaries, so that the mixed disperse dyes have excellent color, coverage, level dyeing, and migration. Color fastness to washing, color fastness to rubbing, color fastness to perspiration, etc.

Abstract

The invention relates to a disperse dye composite and an environment-friendly disperse yellowish-brown dye. The disperse dye is mainly prepared from, by mass, 15-35% of component A, 5-20% of component B, 1-9% of component C and 35-80% of assistant. When the environment-friendly disperse yellowish-brown mixed component is used for dyeing polyester fiber and polyester fiber blended fabric, yellowish-brown fabric which has a bright color and excellent washing resistance, perspiration resistance and rubbing fastness can be obtained; Intertek detection shows that the dyed fabric does not contain forbidden aromatic amine, and the content of heavy metal and the content of irgasan both accord with Oeko-Tex Standard 100 I class indexes.

Description

technical field [0001] The invention relates to a disperse dye composition and an environment-friendly disperse yellow-brown dye, in particular to a disperse dye suitable for dyeing polyester fibers and blended fabrics thereof, and belongs to the technical field of fine chemistry. Background technique [0002] In recent years, the rapid development of polyester fiber and its blended fabrics at home and abroad, and people's requirements for ecological safety and environmental protection performance beyond the basic performance of textiles are constantly increasing. Some dyes are directly included in the banned disperse dyes, and many conventional disperse dyes in the market cannot meet the latest environmental protection indicators in terms of chlorophenol, heavy metal content, and banned aromatic amines. [0003] At present, the development of new structures of disperse dyes is less, and the main research work is on the compounding and synergy between dyes and dyes and auxil...
