Leather and Textile

Enzymes are applied during the preparation, dyeing, and finishing (“wet process”) stages of textile production, and even effluent treatment. Many conventional wet process steps involve the use of high concentrations of harsh chemicals, such as caustic soda. Although these chemicals are broad acting, effective, and low cost, when the energy, water consumption, and resulting fibre properties for the whole process are considered, the more selective enzymatic processes can and do offer significant advantages. In some cases, enzymes are able to provide benefits that are not even possible with conventional chemistry (e.g., biopolishing, which can lead to higher value end products).

  • Wool processing
  • Polyester treatment

 

In the leather industry, apart for effluent treatment, laccases may be used in removal of lignocellulose-containing dung cladding from the animal hides, and in replacing environmentally precarious chrome-based tanning agents in the process of leather making. Moreover, there are natural polyphenols in the animal skins that can be turned by laccase actions into lightfast pigments and can be covalently attached to the leather in a natural dyeing process.
