Abstract

Amylase has been exploited in textile, leather, paper and detergent industries for washing and desizing of fabrics. Previously, it was reported to immobilized on to various compatible matrices by adopting various modified methods to increase its thermal and storage stability. Its immobilization onto bovine serum albumin (BSA) was found to be very significant to prepare its non-toxic and low-cost BSA loaded nanoparticles (BSANPs). In present designed study, Pearl millet amylase loaded olive oil driven BSA nanoparticles (BSANPs). These prepared nanoparticles were made bio-active with standardized 35U of alkaline protease for their biodegradation to allow the controlled release bound amylase. Then, these bio-active enzyme-BSANPs were used as nano-woolen shampoo additives with chosen woolen shampoo named, Wool Shampoo for Sheepskin and Wool Products to test their stain removal efficacy from stained woolen fabric without affecting the delicacy and softness of the chosen fabric. In this study, chosen stains were comprised of daily routine stains of shoe polish and hair color dye cream named, Cherry Blossom shoe polish Black and Garnier Nutrisse Nourshing color crème Black respectively. Sometimes, these stains are very difficult to wash off from the woolen fabric or required couple of pre-washing practices. So, keeping this domestic or industrial washing issue, chosen stains are selected very thoughtfully. And, from this study, an effective washing analysis was carried out to wash off the selected stains form woolen fabric when washed with chosen wool shampoo along with bio-active prepared olive oil driven amylase bound BSANPs solution as compared their washing with chosen wool shampoo alone.
