Brownish-red liquid; risk of color change after finishing High viscosity, especially difficult to dissolve in winter; may separate into layers Moderate hydrophilicity; environmentally friendly |
Used for fixing reactive dyes, sulfur dyes and direct dyes;
Impregnation method
1-3% o.w.f
Use a liquor ratio of 1:10, process at a temperature of 40-50℃ for 20-30 minutes, then dehydrate, dry, and shape.
Padding method
One dip and one roll (10-30g/L) – drying – shaping
The above application method is for reference only.
It is recommended to dilute at a ratio of 1:2–4 before use.
The specific application should be adjusted according to the actual processing conditions of each factory.
