 The active, vulcanized, direct and indigo dyes are particularly low when they are dyed thick and dark on cellulose fibers, especially in the case of large black, red and green blue, which are often lower than grade 1, while the textile products exported to Europe and the United States require more than grade 3 to improve the stability of the products to salt and alkali and to reduce the shortage of the structure of the products themselves. Therefore, the environmentally friendly wet rubbing fastness agent has been specially developed.



1. It can be used for fixing after dyeing cellulose fiber; it can greatly improve the wet friction effect, which can be increased by 1-1.5 grade, reaching more than 3 grade.

 1. impregnation (limited to washing plants)

 Dosage: JV-508:2~4%(o.w.f .)(Depth adjustment)

 Bath :1:10~20

 Process: dyed color cloth (PH≤7)→ impregnated (room temperature, time :20~30 min)→ dried

 2. dipping method: JV-508:30~50 g/L;

 Process: dyed color cloth (PH≤7)→ one dip and one rolling (residual rate :80~85%) drying
