Disperse dye characteristics

Disperse Dyes Under the condition of high temperature hot melt or carrier dyeing bath, the fine particles of disperse dyes spread to the inside of the fiber to achieve the purpose of dyeing after the expansion of polyester. After washing, soaping (removal cleaning if necessary) and removing the floating color are considered. Finish the entire process of dyeing. Disperse dyes can be classified into low temperature type (6 type), high temperature type (5 type), and medium temperature type) in accordance with the performance of dyeing polyester components. Low temperature type is suitable for high temperature and high pressure (dyeing or overflow jet dyeing) or carrier dyeing; high temperature type has better sublimation fastness, and is more suitable for continuous dyeing of hot melt dyeing machine, and is widely used in general printing and dyeing plants; Between the two types of 52 disperse dyes, most of the fixing curve is relatively flat, color stability, in the printing and dyeing plants have also been widely used.
