【Technical field】

The invention relates to the dyeing of polyester fibers, in particular to a method for improving the dyeing fastness of polyester fibers.

【Background technique】

After polyester fibers are dyed with disperse dyes, disperse dyes usually have poor sublimation fastness, which results in poor washing fastness, especially polyester fiber textiles containing elastic fibers need to be set at a high temperature above 180°C , making the problem of poor sublimation fastness of disperse dyes more serious, therefore, the washing fastness that can be achieved by the traditional polyester fiber dyeing method is only 2-3 grades.

Traditionally, the method of improving the sublimation fastness of polyester fiber dyeing is to improve the binding force of dyes and polyester fibers by changing the structure of dyes, so as to improve the sublimation fastness of dyes. Another method to improve the sublimation fastness of polyester fiber dyeing is to use a surface treatment agent containing diamine compounds and non-ionic surfactants to modify the polyester fiber substrate, so that the surface of the polyester fiber substrate With amine groups, it can be dyed with acid dyes to improve the sublimation fastness of dyes.
