BLEACH-811 | All in one Pretreatment Agent

Product Information

Bleach-811 is a very low foaming speciality product for pretreatment of cotton yarn, cotton knits, terry towels and their blends available in powder form. Due to it's unique formulation it acts as a wetting agent, detergent and peroxide stabilizer and also no caustic is required during bleaching. Thus, combined scouring and bleaching can be carried out using only peroxide alongwith Bleach-811. As caustic is not added during bleaching, the total dissolved solids (TDS) of effluent will be low. 

Due to low foaming characteristic, it is suitable for soft flow machines as well as low liquor ratio package dyeing machines and jet dyeing machines.

For Soft flow machine: 

1. Recipe for RFD fabric (Ready for Dyeing fabric:

Bleach-811 : 1.2-1.5 % 

Hydrogen peroxide (50%) : 2-2.5 % 

Celldet-R : 0.2-0.3% 

Temperature : 95-110 deg.C 

Time: 45-15 min  

2. Recipe for Full white fabric: 

Bleach-811 : 1.8-2.2 % 

Hydrogen peroxide (50%) : 6.0-8.0 % 

Celldet-R : 0.2-0.3%
