Abstract
The fabrics of health care function have drawn increasing attention. Herein, AgNO3 was in-situ reduced into nano silver (AgNPs) by aloe extract (AVE) as reducing agent to gain AgNPs@hinokitiol-grafted chitosan (AgNPs@HTCS). The antibacterial and antioxidant cotton fabric were fabricated by LBL method using AgNPs@HTCS as positive layer and hyaluronic acid as negative layer. The results showed that the optimum preparation conditions of AgNPs@HTCS were as follows: AgNO3 10 mmol/L, HTCS 40 v/v %, AVE 15 mL, 80 °C, 6 h. MIC values of AgNPs@HTCS against S. aureus and E. coli attained 1.7 μg/mL and 5.3 μg/mL, respectively. The antibacterial ratio of cotton fabric reached the maximum 99.9 % at very low concentration of AgNPs@HTCS 0.25 g/L. After 3 LBL layers, the antibacterial properties of functional cotton fabric could withstand the acid or alkali washing. After 25 washing cycles, the antibacterial rate of LBL fabric still maintained above 96 %. Compared with the untreated fabric, antioxidant capacity of LBL functional cotton fabric raised approximately two times. LBL functional cotton fabric still retained the wear performances of the original fabric.
