Improvement of wettability of PET fabrics treated by lipase
Source abstract
Abstract
In order to improve the wettability of PET fabric,the PET fabric was treated with lipase.The effect of process parameters of lipase on the wettability of PET fabrics was studied.And the wettability of PET fabrics was characterized by capillary effect.SEM test indicated that the degradation of macromolecules in PET fiber surface has occurred after lipase treatment,and the surface of PET fibers became rougher.Water contact angle from 121.5°of the control decreased to 59°of treated samples,which indicated the wettability of PET fabrics was significant improved.With the increase of the concentration of lipase and treatment time,the capillary height of PET fabrics increased.And the capillary height increased firstly,and then decreased with the increase of pH value and treatment temperature.The optimized pH value and treatment temperature were 7 and 40 ℃,respectively.The results showed that it was feasible for lipase to improve the wettability of PET fabrics.
