This report is a summary of a lecture given by Mr. Chuck Starace of Novo Industries. Two functions of enzymes are discussed: the removal of starch size, and the removal of proteinaceous stains. Several factors affect the use of alpha amylase, a starch-reducing enzyme, including temperature and pH of the bath. Desizing occurs in three steps: impregnation of the fabric with the enzyme solution, breakdown of the size into water-soluble products, and the removal of these breakdown products. Proteolytic enzymes, which break down protein and protein residues, can be used to remove certain stains, such as blood and grass stains and sebum. Proteolytic enzymes are not recommended for use on protein fibers. Proteolytic enzymes can be found in certain nationally marketed detergents and pre-soak products, or can be obtained in liquid form and added to a detergent solution. -- AATA
