Disperse dyes have made new progress in use:
1 multi-component disperse dyes, usually mixed by two (also three or four) disperse dyes in a certain proportion, which increases the dye uptake due to the synergistic effect of the dye.
2 Transfer printing, the disperse dye is made into printing ink, printed on the fabric, and then subjected to high temperature pressing dyeing. This process is also called non-aqueous phase printing, which has the advantages of energy saving, time saving and convenience.
3 Disperse dyes and reactive dyes can be mixed to make one-bath dyeing of polyester-cotton, polyester-viscose and other mixed fabrics, which simplifies the printing and dyeing process and improves the quality of printing and dyeing.
