摘要
以降解壳聚糖(JCH)、3-氯-2-环氧丙基十二烷基二甲基氯化铵(GTMAG)、环氧氯丙烷和β-环糊精(β-CD)为原料,制备了长链降解壳聚糖季铵盐固载β-环糊精(HDCC-β-CD)。采用FT-IR、XRD和XPS对产物进行表征,并将其作为抗菌剂用于亚麻装饰布的抗菌整理,对比了HDCC-β-CD与短链降解壳聚糖季铵盐固载β-环糊精(HTCC-β-CD)处理的亚麻织物抗菌性能的差异。结果表明,与HTCC-β-CD相比,HDCC-β-CD整理的亚麻装饰布抗菌性强,耐水洗性高;固载量为19.48μmol/g的HDCC-β-CD亚麻装饰布对金黄葡萄球菌(S.aureus)和大肠埃希菌(E.coli)的最低抑菌质量浓度为10 g/L。
Long chain degraded chitosan quaternary ammonium salt(HDCC-β-CD)are prepared by the degra⁃dation of chitosan,2,3-epoxy propyl dodecyl dimethyl ammonium chloride(GTMAG),epichlorohydrin andβ-cy⁃clodextrin(β-CD)as raw materials.The product is characterized by FTIR,XRD and XPS.As an antibacterial agent,the application of HDCC-β-CD to linen fabric treatment is carried out.At the same time,comparative study is undergone of antibacterial finishing properties of linen fabrics with HDCC-β-CD and immobilization of short chain degraded chitosan quaternary ammonium saltβ-cyclodextrin(HTCC-β-CD).The results show that HDCC-β-CD has better antibacterial performance and washing durability on linen fabric than HTCC-β-CD.And when the fixed load is 19.48μmol/g,the minimum inhibitory concentration of HDCC-β-CD against S.aure⁃us and E.coli is 10 g/L.
