Effect of Transglutaminase Enzyme on Physico-mechanical Properties of Rambouillet Wool Fiber

摘要

Rambouillet wool fiber was scoured and treated with transglutaminase (TG) enzyme for different concentrations and duration at neutral pH at 45 degrees C. The physical, mechanical, dyeing, and antimicrobial properties of the wool fiber before and after enzymatic treatment were evaluated as per standard methods. Results inferred that TG enzyme-treated wool fiber sample showed improvement in softness, luster, and tensile strength in comparison with scoured wool fiber. It is found that 0.5% TG enzyme treatment at 45 degrees C for 60 min at pH 7 was an optimum condition. Scanning electron microscope images also confirmed the flattened and smooth scales of wool fiber after enzymatic treatment.
