Modification of Ultrafine Wool with Modified Protease

ABSTRACT

The outermost surface of wool comprises a scale layer which hinders certain fabric processing steps and shrink resistance properties of wool fabrics. How to remove surface scale layer without causing severe damage has been an important topic in wool research for decades. In this study, polyurethane was used to prepare the modified protease (MP), the highest activity was obtained at 50°C and pH 7 for the MP. MP was used to treat the surface of ultrafine wool. The resultant surface morphology, chemical groups, and mechanical performance of the treated wool fabrics were evaluated.

摘要

羊毛的最外表面包括阻碍某些织物加工步骤和羊毛织物的抗收缩性能的鳞片层。如何在不造成严重损伤的情况下去除表面鳞片层一直是羊毛研究的一个重要课题.本研究采用聚氨酯制备改性蛋白酶，在50℃和pH7条件下，改性蛋白酶的活性最高.采用改性蛋白酶处理超细羊毛表面.对处理后的毛织物的表面形貌、化学组分和力学性能进行了评价.
