铜离子络合棉针织物的抗菌性研究

Study on antibacterial property of Cu(Ⅱ)complex cotton knitted fabric

主要讨论了棉针织物经过NaOH溶液和铜氨溶液处理后的铜离子含量和抗菌性能.采用扫描电镜、红外光谱、电感耦合等离子体发射光谱以及琼脂平皿扩散法等测试手段,来确定铜离子的存在,并分析了碱处理、铜氨溶液浓度和处理时间对铜离子含量及抗菌性能的影响.结果表明:未经碱处理的和经碱处理的棉针织物与铜氨溶液反应都能够生成铜离子络合棉针织物,且后者中的铜离子含量比前者高;无论是大肠杆菌还是金黄色葡萄球菌,经碱处理的铜离子络合棉针织物的抑菌带宽度都大于未经碱处理的;铜离子的含量与铜氨溶液浓度、处理时间以及织物的抗菌性成正相关.

The Cu （ II ） level and antibacterial property of cotton knitted fabrics treated with NaOH solution and copper ammonia solution was discussed. Scanning electron microscope, FlaIR spectroscopy, inductively coupled plasma emission spectroscopy and agar diffusion plate method were used to investigate the existence of Cu （II） and analyze the influence of alkali treatment, the concentration of cupper ammonia solution and treating time on the Cu （ II） level and antibacterial property. The results show that Cu （ II ） could bond to cotton knitted fabric whether treatment with alkali or not; Cu （ II） level is higher on the alkali treated fabrics, and the bacteriostatic belt width the same situation is happened either for Escherichia coli or Staphylococcus aureus. The Cu （II ） level is positively correlated with the concentration of cupper ammonia solution, treating time and the bacteriostatic belt width of the fabric.
