Effect of plasma-protease combined treatment on shrink-resistance of wool fabrics

In order to improve the shrink resistance of wool fabrics,surface modification of the wool fabric was carried out by low-temperature plasma-protease combined treatment.The shrink resistance and strength of the fabric before and after treatment were investigated.The morphology of the treated fabric was observed by using SEM,and the surface molecular structure was characterized using infrared spectroscopy.The result showed that the morphology of the treated fabric has changed,with shrinkage reduced to 5.4% and strength basically retained.As a result,low-temperature plasma-protease combined treatment renders wool fabrics good shrink resistance.
