Abstract: Abstract In order to improve the shrinkproofing of wool fabrics，surface modification of wool fabrics was carried out by low-temperature plasma/protease treatment.The change in the shrinkproofing and breaking strength properties of the treated fabrics. The change in the morphology and microstructures of the treated fabrics were investigated by using SEM, FTIR and X-Ray diffraction. The result showed that the treated fabrics can not only get 5.4% shrink proof but can preserve intrinsic strength. As a result, Combining low-temperature plasma pretreatment and protease to treat make wool fabric has well shrinkproofing.

Key words: wool fabric, protease, low temperature plasma, shrinkage resistance
