Abstract

Enzymatic treatments have gained popularity in the textile industry because of environmental friendly and energy conserving alternatives. Advancement in biotechnology and modification of enzymes has been focused based on various textile process applications. All the manufacturing steps of textile chemical processing, enzymes are using for implementations of the green technology to meet up the challenge of fourth industrial revolution. In this category, amylases, peroxidase used for desizing and bleaching, cellulase activates for bio polishing and denim finishing. This chapter summarizes the current developments of enzyme technology and highlights the environment-friendly and sustainable enzymatic textile processing in the textile industry.

Highlights

  • Enzymes are biocatalysts obtained from living cells through biochemical reactions metabolic process of the cells [1]

  • Enzymes obtained from the natural source since ancient times in the production of food products, such as cheese, sourdough, beer, wine, vinegar and indigo formation [2]

  • Most of the enzyme applications in textiles are confined to cotton processing: removal of impurities; biofinishing to improve appearance; bio-stoning or stone washing of denims to produce the fashionable aged look; bleaching cleanup to remove residual H2O2 before dyeing [13–17]

Summary

Introduction

Enzymes are biocatalysts obtained from living cells through biochemical reactions metabolic process of the cells [1]. Enzymes obtained from the natural source since ancient times in the production of food products, such as cheese, sourdough, beer, wine, vinegar and indigo formation [2]. The development of fermentation processes has grown during the last century, for the production of purified enzymes in a large scale [3]. The use of recombinant gene technology has improved enzyme-manufacturing processes. Most industrial enzymes occurred hydrolysis for degrading the natural substances [4]. Enzymes are used in food production and pharmaceuticals, textiles, leather processing [5–7].
