BIOFEEL-PST (CONC). | Biopolishing Enzyme

Biofeel-PST(Conc). is an acid cellulase enzyme for bio-polishing of cellulosic and polyester/cellulosic blends. The product is to be used in garment dyeing machine and jet dyeing machine where the suitable mechanical action is provided which enhances the action of Biofeel-PST(Conc). It is also suitable for colour fading for denim garments and bio-polishing of knits, fabrics & terry towels.

To avoid excess strength loss of garments and materials after biopolishing, it is recommended deactivation of Biofeel-PST (Conc). after the treatment.

1.For Biopolishing of cottons and blends in exhaust after pretreatment :

• Biofeel-PST (Conc). : 0.5% - 0.8%
• pH: 4.7 - 5.5
• Temperature : 50-60 deg.C
• Treatment time: 30-60 min

Dosage should be based on cotton component only.

1. Biofeel-PST(Conc) to time: after adjustment of pH & temperature of bath.
2. After the bio-polishing treatment, raise the temperature to 70 deg.C and/or adjust pH to 10 to terminate action of enzyme. The material can then be finished using chemical finishes as usual.
3. Combined bio-polishing and peroxide elimination can be carried out for cotton knits and terry towels prior to reactive dyeing. Bio-polishing is usually recommended before cationic dye-fixation or cationic softening.

Storage : Store in cool, ventilated shed away from heat and direct sunlight. Storage temperature should not exceed 35 deg C.Close lids firmly to avoid contact with air and moisture.
