利用壳聚糖对棉织物进行抗菌整理，使其具有抗菌性能。考察了壳聚糖的浓度、相对分子质量和脱乙酰度对大肠杆菌和干草杆菌抑菌活性的影响。细菌减少使用改进的Quinn方法进行评估。以0.3g/L壳聚糖溶液和0.5g/L干草杆菌溶液对大肠杆菌和干草杆菌的抑制效果较好。经戊二醛和壳聚糖处理的棉织物具有良好的抑菌性能。给出了棉织物表面的红外光谱和纤维的扫描电子显微镜照片。
Chitosan is used to treat cotton fabric's to impart antibacterial activities. The effect of concentration, molecular weight, and degree of deacetylation of chitlosan on antibacterial activity to Escherichia coli and the Hay bacillus is investigated. Bacteria reduction is evaluated using the modified Quinn method. Escherichia coli is effectively inhibited at 0.3 g/l chitosan solution and the Hay bacillus at 0.5 g/l. To bond chitosan to fabric chemically, glutaric dialdehyde is chosen as the crosslinking agent. Cotton fabrics treated with glutaric dialdehyde and chitosan show a good ability to inhibit bacteria reproduction. IR spectra of the surface of cotton fabrics and SEM pictures of fibers are presented.
