Effect on Wool Properties by Using Casein and Transglutaminase

摘要：

In this paper, casein, a natural polymer, was used as a surface-coating material for improving wool fabric properties mediated by a microbial protein cross-linking enzyme: Transglutaminase (TGase). For the wool fabric used in this study, casein (2 g/L) treatment for 1 h combined with 20 U/g fabric of microbial TGase reduced the area shrinkage of the KMnO4 pretreated wool fabric from 11.32±0.26％ to 4.57±0.15％. The tensile strength recovered from 275±5.0 N to 315± 2.1 N. The casein cross-linked on wool exhibited better stability in warm water, Na2CO3 and SDS solutions. Scanning electron micrographs demonstrated that the casein material induced by TGase smoothed the wool fiber surface by coating or filling the raised scales of the wool.
