Peroxide removal

Introduction :
Americos Catalase XL is highly effective in catalyzing the decomposition of hydrogen peroxide into oxygen and water. In textiles processing, this is often the most preferred mode of hydrogen peroxide removal after the bleaching step as the enzyme and the breakdown products are totally inert to Reactive dyestuffs.

Americos Catalase XL enzyme accommodates a broad pH and temperature range and remains effective even at high concentrations of hydrogen peroxide.

Advantages

• Enzyme is completely biodegradable
• Highly effective hydrogen peroxide removal
• Effective over a broad temperature range
• Works well at any residual peroxide level
• Reduces water consumption
• Enzyme and the breakdown products (water and oxygen) have no effect on dyestuffs
• Increase dyeing productivity

Removing Hydrogen Peroxide with Americos Catalase XL



Americos Catalase XL removes hydrogen peroxide with very simple system with cost effectiveness and reliability Excess reducing chemical used ? H₂O₂ removed but excess reducing chemical affects dyeing Insufficient reducing chemical used ? H₂O₂ not fully removed and affects dyeing

Removal of Hydrogen Peroxide :
Hydrogen peroxide and other peroxy compounds are commonly used for bleaching in preparation of cellulase based fabrics and yarns. If not completely removed, hydrogen peroxide will cause shade change with some fiber Reactive dyes. Even a small amount of residual hydrogen peroxide, particularly left in creases and folds of fabric, causes change in cast of dye resulting in uneven dyeing.
