摘要：

In order to improve the hydrophilic property of polyester fabrics, cyclodextrin as the raw material was oxidized by oxidant sodium periodate into aldehyde derivatives, and polyester fabrics were successively rolled-baked-cured through the solution of chitosan and cyclodextrin dialdehyde. The influence of different mass concentration and molar ratio of reactants on the hydrophilic property of polyester fabric was investigated. The results show that when the chitosan mass concentration is 3%, cyclodextrin derivatives mass concentration is 80 g/L, the molar ratio of cyclodextrin units of glucose and sodium periodate is 1: 1, the modified polyester fabric moisture regain rate reaches 2.28%, and compared to original cloth, it has been improved 1.88%. The contact angle dropped to 0 within 2 s. The weight loss ratio of modified fabric was controlled under 7% after washing for 30 cycles.
