Abstract
This chapter discusses the application of enzymes in synthetic fibres for improving the functional properties such as moisture and surface aspects. Synthetic fibres are being playing in major role in textile applications such as clothing, hygienic, sports, industrial uses like protection and ballistic etc. These synthetic fibres made from polymer source like polyester, nylon, polyethylene, and polypropylene or regenerated from natural source such as viscose rayon, modal, lyocell and tencel have been widely accepted for their care properties, versatility and long life. In spite of such acceptance, certain drawbacks concerning their hand properties, thermal properties, and moisture absorbency can be enhanced by introducing hydrophobic block copolymers. However, this modification can lead to problems of longer drying time, excessive wrinkling, and wet cling. In this chapter the properties of the synthetic fibres and their structural modifications made by the many researchers both chemical and biochemical treatments have been discussed. The latest developments and research going on the enzyme biotechnology on various fibres such as polyester, polyamide, regenerated cellulosic fibres, and biodegradable plastics have been discussed.
