环糊精接枝纺织纤维的研究进展

对纺织领域常用的几种环糊精接枝纤维的改性方法及原理进行了综述.对纤维素纤维的改性可采用环氧氯丙烷活化纤维素法、一氯均三嗪改性环糊精、醛类交联剂和多元酸交联剂固载法等,根据不同的需求来选择相应的接枝方法;对于壳聚糖纤维的接枝改性可通过将环糊精改性制成环糊精醛来进行;对于聚酰胺纤维的接枝改性可使用含有磺酸基的β-环糊精衍生物来进行;对于羊毛、真丝纤维则利用其它的环糊精衍生物来进行改性处理.不同纤维,其化学改性方法不同;同一种纤维根据使用要求可采用不同的化学方法进行改性.整理后的纤维既能体现本身的优良性能,又可发挥环糊精包合性能,这为开发功能性纺织材料提供了参考依据.

Research progress of textile fibers grafted by cyclodextrin

The modified methods and principles of cyclodextrin(CD) grafting usually-used fibers are reviewed.The cellulose fibers are modified by cyclodextrin through some methods such as epichlorohydrin,Monochlorotriazinyl-β-cyclodextrin,aldehyde and multi-acid as cross-linking agent respectively,which are employed according to different demand;cyclodextrin monoaldehyde is grafted onto chitosan fiber by inclusion property of its cavity;cyclodextrin could be immobilized to polyamide fiber by cyclodextrin derivatives with sulfo group;wool and silk fibers are modified by other cyclodextrin derivatives.For different fibers,the methods of chemical modification are various,even the same fiber may has different modification ways according to its application.Treated fibers have both their performance and inclusion property of CD.It is helpful for the research and development of functional textile materials.
