Effect of chemical and enzymatic modification on the performance of wool
In this paper, transglutaminase, a protein-crosslinking enzyme, combined with peroxide pre-treatment and protease was applied for the modification of the wool fibre. The influences of the various preliminary agents, protease and transglutaminase treatments on the wool shrinkage resistance, fiber damage and fabric strength were discussed. It was shown that H2O2 pretreatment resulted in less damage to wool than chlorination. And protease treatment combining with H2O2 pre-treatment could impart a significant reduction in fabric shrinkage and an increase in whiteness, but proteolytic action was not uniform and caused excessive damage to the wool fiber.The results indicated that transglutaminase could repair function in wool damage following chemical pre-treatment and protease anti-felting finishing, resulting in an increase in wool fabric strength and a decrease in alkali solubility. The wool shrinkage resistance could be improved, while damage to the wool fiber could be controlled by using this new modification process combining hydrogen peroxide, protease and transglutaminase.
