Abstract:

Aiming at the problem on the influence of different copper ion loaded finishing agents on the antibacterial performance and other use performances of cotton fabris, 3 kinds of copper ammonia solution are chemical reaction products made with different ratios of copper sulfate and sodium hydroxide. And then cotton fabrics are finished by 3 kinds of copper ammonia solution, with bath ratio of 1:30, a time of 20min and copper ion concentrations of 0.025M, 0.05M, 0.075M, 0.1M, 0.15M, 0.2M, 0.4M. Finally, antibacterial properties, breaking strength, and levelling ability are tested by quantitative agar diffusion method, the strip method and K / S method. The results show that: compared with the other two copper ammonia preparation program, when n (NaOH): n (CuSO4) = 1: 1 solution of copper ammonia complex is used to finish cotton fabric, fabric will present best antimicrobial performance with low degree of fabric damage and level dyeing property.

Key words: antibacterial agent loaded with copper ion, cotton fabric, antibacterial, complexing
