Application:
1. Direct fast-resistant turquoise blue GL dyed cotton or viscose fiber has bright emerald blue. The dyeing rate is general, the leveling property and the transferability are poor. When dyeing, salt should be added to control the dyeing to obtain uniform color. The highest dyeing temperature is 100 °C.
2. Direct fast-resistant turquoise GL is used for dyeing rich fiber, the dyeing rate is poor, the color is lighter than cotton, and it is also used for the dyeing of silk, wool and nylon. When dyeing vinyl fabric, the dyeing rate is worse than cotton, the color ratio is Viscose fiber is blue. When cotton, viscose fiber and other fibers are dyed in the same bath, silk and wool are lighter than cotton and viscose fiber, nylon and diacetate are slightly stained, triacetate, polyester and acrylic. Almost no staining (some products have stained polyester and acrylic).
3. Direct fast-resistant turquoise GL can be mixed with disperse dyes at high temperature to dye polyester-bonded fabrics. The dyeing bath is heated to 120 ° C under neutral conditions, or loaded with boiling dye. After the dyes are dyed with polyester, cool down. After dyeing for half an hour, the cellulose fibers are fully colored, and the dye is exhausted, and the color light is basically unchanged.

Mainly used for dyeing and printing of viscose fabric, also used for cotton knit, cotton skein and viscose skein Dyeing or printing. It is not easy to dye dark, and the dyeing amount of dyeing or dip dyeing usually does not exceed 3% (owf), the dosage is increased, and the color is no longer deepened.
