Textile substrate

Textile substrate is a term used to describe a substance witch upon an enzyme reacts (surface treatments) In other words, compounds that undergo reactions with enzymes. Included are different colorants dyes, natural sizing and thickener materials, such as starches and cellulose derivatives, etc.

The common textile substrates for enzymes are natural fibres. However, synthetic fibres have also been subjected to enzymatic treatments. The reason of most enzyme treatments is the modification of the fibre surface to enhance the hand and appearance of the fibre. One example of such fibre modification are the treatment of cotton denim with cellulases to enhance the comfort or achieve washed worn look jeans, soft jeans or as colour brightener (bio-polishing). Furthermore, other purposes are removal of not wanted by-products such as pectin’s. Furthermore, a few synthetic fibres have been explored to enzymatic modifications in the form of textile substrates, for special applications such as bio sensors or membranes. However, synthetic fibre such as polyester is made of oil derivatives. Nevertheless, synthetic fibres are huge, created in chemical laboratories to a achieve wanted property at competitive prices, and sometimes they can be the best alternative.
