Hydrogen peroxide low temperature activating agent GR-F102 is one
kind of our company new developed oxidation system-H2O2/activating
agent oxidation system, which could make H2O2 decomposition effectively
at the temperature of 60-80 centigrade. It could effectively remove the
impurities of cotton fiber xylogen, pectic substance,etc. to achieve the
bleaching effect. And it could save time and reduce cost to actualize the
energy conservation and emissions reduction of environmental protection.
This products applies into pretreatment bleaching of cotton yarns, bobbin,
towels, knitting and tatting fabric.

Intermittent pretreatment process
1.Caustic soda 2-3g/L; Hydrogen peroxide (100%) 2-3g/L; Penetrating agent 0.5g/L
2.Hydrogen peroxide activating agent dz-01 0.8--1.2g/L
Cold heap process
Pretreatment agent CY-P 15g/L
100% H2O2 20-25g/L
NaOH 20-35g/L(Depending on the gray cloth specification)
Hydrogen peroxide activating agent 2-4g/L
Gray cloth dipping and rolling liquid (Room temperature, two times of
dipping and rolling, the rolling weight percentage is 90%-100%)
Cold heap time needs 20-24 hours.
Water washing temperature is 95-100°C And hot water washing above 4th level.
1.If the water washing temperature is less than 95°C, suggest that adding non-ionic penetrating agent or
washing agent 2-4 grams per litter into the 1st level hot water washing tank.
2.Materializing sequence: Turn on the blender and put light alkali and water about 400liters. Add CY-P and
hydrogen peroxide. Then add hydrogen peroxide activating agent which should be prepared using cold
water in advance when it is about to be used. Have sufficient liquid 500 liters and stirring for 3-5 minutes.
3. Normal oxygen bleaching process after desizing and souring
1) Alkali scouring process
NaOH:50-55 g/L (Pure cotton), 15-30 g/L (Polyester-cotton).
Refined Penetrant dosage: 2-6 g/L
Chelating disperse agent: 1-2 g/L
The front steaming box is 100-200 degrees for 60minutes.
2) Oxygen bleaching process
NaOH: 5-10 g/L
100% H2O2: 6-12 g/L
Pretreatment agent CY-P dosage: 4-12 g/L
Hydrogen peroxide activating agent: 2-4 g/L
The rear steaming box is 70-80 centigrade and steaming for 60-70minutes.
4. One-step steaming process
NaOH: 15-30 g/L
100% H2O2: 20-25 g/L
Hydrogen peroxide activating agent: 2-4g/L
Pretreatment agent CY-P dosage: 15-20 g/L
Rolling weight percentage is 80%-100%. Steaming box 50-60 centigrade for 60-70minutes. 95-100
centigrade hot water washing.
