Neutral cellulase for textile Conzyme N-5000

PRODUCT DESCRIPTION

Conzyme®N-5000 is high concentrated and neutral cellulase preparation, which is designed specially for denim abrasion process. It is only recommended for formulations that are used in bio-washing of denim garments and acts on denim garments to impart high abrasion and fading effect, which can also be used for the processing of the cotton, hemp, viscose, yarn and lyocell.

MECHANISM

Cellulose is a glucose polymer linked with β-1,4-glycosidic bonds. Cellulase system consists of three major components: endoglucanase (endo-1,4-β-D-glucanase or EG), cellobiohydrolases (exo-1,4-β-D-glucanases, or CX, or CBH), and β-glucosidases (1,4-β-D-glucosidase; BG; BGL). As illustrate in the below diagram, these activities work synergistically on cellulose and efficiently convert cellulose into glucose. The product is so designed as to help with enzymatic abrasion of demin without harming the fabric.

BENEFITS

1. Excellent bio-polishing effect

2. Clean and even fabric surface

3. Softer hand feel

4. Brighter colors

5. Environmental-friendly and Bio-degradable

SAFE HANDLING PRECAUTIONS

Enzyme preparations are proteins that may induce sensitization and cause allergic type of symptoms in susceptible individuals. Prolonged contact may cause minor irritation for skin, eyes or nasal mucosa. Any direct contact with human body should be avoided. If irritation or allergic response for skin or eyes develops, please consult a doctor.

WARNINGS

Keep sealed after use every time to avoid microbial infections and inactivation of enzymes until its finish.
