Uses
Direct blue GL has bright color and good light fastness. It is one of the commonly used dye varieties. Mainly used for dyeing and direct printing of cotton and viscose fabrics. The dyeing rate is average, and the levelness and migration are poor. Immediately after dyeing, color-fixing treatment will be performed, otherwise, color blooms will occur due to dye migration. After treatment with fixing agent Y, the color and light are basically unchanged; after treatment with color-fixing agent M or finishing with resin, the color and light are all green. It can be used for dyeing and printing of silk, wool and nylon, and can also dye polyester-viscose blended fabrics with disperse dyes in the same bath. Polyester is basically non-staining.
