Abstract: In order to improve the moisture absorption of high-density cotton-like PET knitted fabric, NaOH and 1227 cationic surfactant were used to treat the fabric. The effect of NaOH concentration on the moisture regain, wicking height and bursting strength of the fabric was also discussed and the optimal parameters were as follows: the concentration of NaOH 0.6 g/L, the concentration of 1227 cationic surfactant 3 g/L and the treatment time 60 min. The properties such as moisture absorption, capillary effect and softness of highdensity cotton-like PET knitted fabric were improved under optimum parameters, and the bursting strength decreased in a small degree.
