Usage of Enzymes in Textile Processing:Today enzymes have become an integral part of the textile processing. Though enzyme in desizing application was established decades ago, only in recent years the application has widened
with new products introduced. With the increase in awareness and regulation about environment concerns, enzymes are the obvious choice because enzymes are biodegradable and they work under mild conditions saving the precious energy. Enzymes being
biocatalysts and very specific are used in small amounts and have a direct consequence of lesser packing material used, the transportation impact is lower. In an overall consideration enzymes are the wonder products. • Low energy requirements, mild conditions of use, safe to handle, non- corrosive in their applications. • On account of lesser quantities of chemicals used in process as well as ease of biodegradability of enzymes results in reduced loads on ETP plants. • Enzymes under unfavorable conditions of pH or temperatures chemically remain in same form but their physical configuration may get altered i.e. they get “denatured” and lose their activity. For this reason live steam must never be injected in a bath containing enzymes and any addition of chemicals to the enzymes bath must be done in pre-diluted form. • Compatibility with ionic surfactants is limited and must be checked before use. Nonionic wetting agents with appropriate cloud points must be selected for high working efficiency as well as for uniformity of end results. • High sensitivity to pH, heavy metal contaminations and also to effective temperature range. Intense cautions are required in use. Enzymes for cellulosic textiles
