| Abstract: | A new type of L-arginine/carboxymethyl chitosan antibacterial cotton fabric was prepared by using the binder carboxymethyl chitosan which linked L-arginine to the surface of cotton fiber via a one-pot method.Color experiment of sakaguchi reaction,conductometric titration,SEM,FTIR and antibacterial were used to test,and the reaction mechanism was explored through simulation experiments.The results indicate that L-arginine was successfully grafted on the surface of cotton fiber.The optimal input of carboxymethyl chitosan and L-arginine was optimized to be 0.2 wt%and 0.2 wt%,respectively.The L-arginine/carboxymethyl chitosan cotton fabric has good antibacterial properties,and the inhibition rates of Escherichia coli and Staphylococcus aureus were up to 87%and 80%,respectively. |
