Accelerated Bleaching of Cotton Material with Hydrogen Peroxide

Abstract

Abdul SB and Narendra G

Nowadays, consumers increasingly demand more environmentally friendly products. This also affects the textile industry, and thus, aspects such as control of water, energy and chemicals consumption should be taken into account in textile processes. Hydrogen peroxide (H2O2) is the most widely used bleaching agent for textiles and came into use around. Hydrogen peroxide is suitable for most fibers and it can be used in a wide range of machines under different conditions. Reaction products are non-toxic and non-dangerous it is applicable in strongly alkaline medium and it requires a high temperature to give the most effective bleaching. Recent research in our laboratories has focused on the development and application of compounds that enhance the bleaching process. In this investigation in order to optimize time and temperature of bleaching process various experimentations were carried out, this study reveals that, a) an increase the temperature the rate of bleaching is increases & correspondingly reduction in process time. b) An increase in concentration of (H2O2) whiteness and weight loss is increases c) Hardness of water inversely proportional to whiteness & directly proportional to weight loss. d) The concentration of peroxide stabilizer is inversely proportional to the whiteness and directly proportional to weight loss.
