ABSTRACT:
Disclosed is a process for chemical finishing of fabrics, fibers or yarns wherein insoluble cellulosic polymers are reacted with carboxylic acids or esters thereof in the presence of a lipase. The cellulosic polymer may be cotton, viscose, rayon, lyocell, flax, linen, ramie, and all blends thereof; and blends thereof with polyesters, wool, polyamides, acrylics and polyacrylics. The lipase may be a microbial lipase, including a lipase obtained from yeast, e.g. Candida lipase, a bacterial lipase, e.g. Pseudomonas lipase, or a fungal lipase, e.g. Humicola or Rhizomucor lipases. Chemically modified lipases obtained by coupling polyethylene glycol to amino acid residues of the lipase may also be used.
