【摘要】 利用壳聚糖对棉织物进行整理来赋予织物抗菌活性。研究不同浓度、分子量和脱乙酰度的壳聚糖对大肠杆菌和枯草杆菌抗菌性能的影响。采用改良的Quinn方法来测定棉织物的抗菌率,为了使壳聚糖牢固地固着在棉织物上,选用戊二醛作交联剂,整理后的棉织物具有优异的抗菌性。更多还原

【Abstract】 Chitosan was used to treat cotton fabrics to impart them with antibacterial activities.The effect of concentration,molecular weight,and degree of deacetylation of chitosan on the antibacterial activity to Escherichia coli and the Hay bacillus was investigated.Bacteria reduction was evaluated(using) the modified Quinn method.To bond chitosan chemically to the fabrics,glutaric diadehyde was chosen as the crosslinking agent.Cotton fabrics treated with glutaric diadehyde and chitosan showed a good ability to inhibit bacteria reproduction.更多还原
