壳聚糖改性竹浆抗菌织物的耐水洗性能

The Water Resistance of Chitosan Modified Bamboo Pulp Antibacterial Fabrics

讨论了经表面壳聚糖改性处理前后的Cu(Ⅱ)络合竹浆针织物的抗菌性能及耐水洗性能.采用扫描电镜、红外光谱、琼脂平皿扩散法等测试手段确定Cu(Ⅱ)的存在及织物的抗菌性能,并运用SPSS 19.0软件对数据进行统计学分析.研究结果表明:未经壳聚糖改性处理的竹浆抗菌针织物在水洗10次后抑菌圈带宽显著减小,降低了10.11%,但水洗50次和10次对比,并未出现显著性差异;而表面经壳聚糖改性处理后,Cu(Ⅱ)抗菌织物抑菌圈带宽有所下降,其在水洗10次、50次之后与水洗0次相比分别下降了1.10%和6.04%,其抑菌圈带宽检验未出现显著性差异,耐水洗性能优良.表面接枝壳聚糖后,竹浆抗菌针织物的耐水洗性能有所提高.

The water resistance and antibacterial properties of copper ion complex bamboo pulp knitted fabrics with or without chitosan modification treatment were discussed. Scanning electron microscopy, Fourier transform infrared spectroscopy, agar plate diffusion method and some other methods were adopted to determine the existence of copper ions and antibacterial properties of fabrics. SPSS 19.0 software was used for statistical analysis. The research results show that the inhibition zone bandwidth of bamboo pulp antibacterial knitted fabrics decreased after the chitosan modification treatment. The inhibition zone bandwidth of fabrics without chitosan modification treatment decreased 10.11% after ten times washing, and there is no significant difference after being washed ten times and fifty times in water. However, the inhibition zone bandwidths of fabrics with chitosan modification treatment decrease from 1.10% to 6.04 % after being washed ten times and fifty times compared to that of fabrics without washing, which indicates that the inhibition zone bandwidths have no significant difference after washing and its water resistance is higher. It illustrates that bamboo pulp antibacterial knitted fabrics with chitosan modification treatment has higher water resistance.
