Industrial Applications in Bangladesh
Bangladesh Market Context: Catalase (Peroxide Killer) saves Bangladesh knit dye houses 1–2 hot water rinse baths per batch by decomposing residual H2O2 into water and oxygen in 15 minutes right inside the dyeing vessel.
- Bio-Polishing Cellulase: Removes surface micro-fibrils and pilling fuzz from cotton knitwear (Grade 4.5 pilling resistance) with <2.5% strength loss
- Catalase (Peroxide Killer): Completely eliminates residual H2O2 after bleaching prior to reactive dyeing without draining the bath
- Denim Abrasion Granular & Liquid Cellulase: High-contrast stone-free vintage look in garment washing plants
- Alpha-Amylase: Rapid starch size removal on woven cotton/blended grey fabrics across 40°C–95°C
