Description
Technical Field
The invention belongs to the technical field of disperse dyes, and particularly relates to an environment-friendly disperse red dye mixture.
Background
With the improvement of living standard of people, sportswear fabrics are more and more favored by people, the sportswear fabrics mainly comprise chemical fiber elastic fabrics, such as polyester-polyurethane fabrics, which are mainly dyed by disperse dyes, and the general disperse dyes can be used for dyeing, although the loose colors of the cloth surface can also be cleaned in a reduction cleaning mode, when the finished cloth is shaped at high temperature, the dyes in the polyester and the spandex are easy to migrate to the surface of the cloth, especially the dyes in the spandex (the glass transition temperature of the spandex is much lower than that of the polyester), so the color fastness of the polyester-polyurethane fabrics is poor, especially the water washing fastness and the sublimation fastness, and therefore the polyester-polyurethane fabrics put higher requirements on the color fastness of the disperse dyes. The scarlet is one of the main colors of the fabric of the sportswear, the dispersed scarlet is 153 bright in color and wide in application, but for the polyester-polyurethane cloth, the washing fastness and the sublimation fastness of the polyester-polyurethane cloth are poor, the fastness requirement of the polyester-polyurethane cloth is difficult to meet, and the content of chlorobenzene and toluene chloride in the dye is high, so that the requirement of ECOPASSPORT 2022 is not met. Therefore, the market needs to develop disperse scarlet dyes which have good washing fastness and sublimation fastness and meet the requirements of ECOPASSPORT in 2022 by the content of chlorinated benzene and chlorinated toluene.
Disclosure of Invention
