Abstrakt: The article discusses the use of reverse proteolysis in the surface modification of cashmere fibers. Cashmere refers to the fine under hair of goats produced in the extreme climates of Northern China, Afghanistan and Iran. There are two possible mechanisms whereby amino acids can be bound on to the surface of cashmere. The first involves the enzyme chymotrypsin which can form a peptide bond between phenylalanine and the side chain amino group from lysine in low water systems. The second mechanism involves the use of a pretreatment with a second proteolytic enzyme to create active groups. The presence of the target amino acids on the surface of cashmere allegedly need to be confirmed to carry out the reactions.
