Abstract:
In order to improve the hydrophilic property of polyester fabrics, cyclodextrin as 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 fo different mass concentration and molar ratio of reactants on the hydrohilic 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 mole ratio of cyclodextrin units of glucose and sodium periodate is 1:1, the modified polyester fabric moisture regain rate reach 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.
Key words: polyester fabric, β-cyclodextrin dialdehyde, chitosan, hydrophilicity
