Abstract

Textile processing is an ever-growing industry that has traditionally used a lot of chemicals, energy and water but due to the environment hazards and high costs of these chemicals, investigation is under way throughout the world to replace chemical de-sizing with economically attractive and eco-friendly bioprocesses. Present study describes the comparison of traditional de-sizing to bio-based de-sizing method and optimization of conditions for fabric de-sizing through crude amylase. In the present study, fermentative de-sizing potential was found maximum at 72 hrs with no surface destruction of fabric. Optimum fabric de-sizing to TEGEWA scale 9 was observed in 5N HCl within 1 hr. Optimization of de-sizing conditions for amylase showed maximum activity at 60°C within 15 hrs, 1000 IU/ml of amylase and 0.5% Triton-X. After process optimization, de-sizing efficacy was checked through weight loss and water absorbance and both parameters were found similar for enzyme and commercially de-sized fabric. Through SEM micrographs enzyme de-sized fabric was found free from any starch particle similar to industrially de-sized fabric which ensure the efficacy of bioprocess.
