Removal of Residual Hydrogen Peroxide in Cotton Bleaching using Catalase Enzyme

Abstract

Industrial use of biotechnology is bringing about new products and processes aimed at the use of renewable resources, as well as the application green technologies with low energy consumption and environmentally healthy practices. Textile processing is a growing industry that traditionally has used a lot of water, energy and harsh chemicals. Due to the ever-growing costs for water and energy worldwide investigations are carried out to substitute conventional chemical textile processes by environment-friendly and economically attractive bioprocesses using enzymes. In the present study, Catalase enzyme is used to investigate the efficacy of removal of residual hydrogen peroxide after bleaching. An alternative cleanup option for hydrogen peroxide based bleaching by this option instead of chemical reducing agents found to be useful in saving water in successive washing, energy, cost and processing time beside significant improvement in dyeing of cotton fabrics with a reactive dye subsequently.
