Textile Pretreatment Agent, Catalase Liquid Enzyme Only Reacts with
Catalase Liquid is a kind of enzyme preparation fermented by
Aspergillus Niger; it can effectively catalyze / decompose hydrogen
peroxide into oxygen and water.
It only reacts with hydrogen peroxide.
low energy and water consumption requirements are increasingly used
in pre-treatment processes for bleach clean up before dyeing
- Water saving: only one cold rinsing is required
- Time saving: reduce rinsing time, the bleach clean up only need
- Energy saving: shorten processing time and no heating
- Safety: hydrogen peroxide can be completely broke down before
1. Drain the spent bleaching liquor
2. Fill with fresh cold water to obtain a liquor ratio suitable for
3. Check that pH is in the range 5-10 (6-7 is most suitable) and
temp 20-60 centi.
4. Add 0.1-0.2g/l diluted catalase liquid and start circulation
5. Check after 10-20 min
6. Continue with dyeing in the same bath
1. When the density of H2O2 is higher than 1000 PPM, the enzyme CANNOT work well.
2. The activity of enzyme will be the best at 50℃, but it is NOT
recommended to dye directly if treated at 50℃.
3. After treated for 10~20min, you can use the MDRCK test paper to
test the density of residual H2O2.
