二醛β-环糊精/壳聚糖改性对涤纶织物亲水性能的影响
|
摘要
为提高涤纶织物的亲水性能,通过高碘酸钠氧化β-环糊精制备二醛β-环糊精,将涤纶织物依次于壳聚糖溶液、二醛β-环糊精溶液中进行轧—烘—焙处理,得到改性涤纶织物。探究高碘酸钠用量(高碘酸钠与脱水葡萄糖单元的量比)、二醛β-环糊精质量浓度与壳聚糖质量分数对改性涤纶织物亲水性能的影响。结果表明:在脱水葡萄糖单元/高碘酸钠的量比为1∶1、壳聚糖质量分数为3%、二醛β-环糊精质量浓度为80 g/L的条件下,二醛β-环糊精/壳聚糖交联改性涤纶织物的回潮率高达2.28%,相比原涤纶织物提高了1.88%,接触角在2 s内下降为0;改性后涤纶织物经过30次皂洗后质量减少率控制在7%以内。
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.
