At present, more than 50 percent of China’s printing ink is disperse dye ink, used for polyester fiber and other chemical fiber fabric printing. Disperse dye is a kind of non-ionic dye, low water solubility, dyeing with the help of dispersant, mainly in the water in a highly dispersed state.
Reactive dye inks account for about 29 percent, mainly used for silk and cotton fabric printing; Reactive dyes, also known as reactive dyes. It is a dye that reacts with fibers when dyeing. The separation of this dye contains a chemical reaction with the fiber of the gene, dyeing dye and fiber reaction, the formation of a common price bond between the two, as a whole, improve washing resistance and resistance to friction fastness. Reactive fuel molecules include parent dyes and reactive groups. Groups that can react with fibers are called reactive groups. At present, it is mainly used for cotton, general hemp, silk and other woven fabrics and knitted fabrics, or fabrics containing higher components.
