Study on the process of knitted woolen fabric treatment based on oxygen low-temperature plasma

The oxygen low-temperature plasma (LTP) treatment on knitted woolen fabric was carried out to investigate the changes of shrinkage resistance, bursting strength and moisture absorption of knitted woolen fabric after treatment. In addition, the effects of different levels of exposure time, treatment power and gas flow rate on the change of felting rate, bursting strength and moisture absorption of knitted woolen fabric in the process of LTP were investigated. The results show that LTP treatment can improve the anti-felt, bursting strength, moisture absorption of knitted woolen fabric. According to the analysis of variance, in the process of LTP treatment, the exposure time is the primary factor that affects the degree of change in the hygroscopicity of knitted woolen fabric, and treatment power is the main factor that affects the degree of change in the shrinkage resistance of knitted woolen fabric. Finally, under the experimental conditions, the best treatment process of knitted woolen fabric by oxygen low-temperature plasma is 20 min, 150 sccm and 400 w.
