摘要: 真丝织物无醛抗皱整理一直是人们研究的热点。文章用聚乙二醇(100)对柠檬酸进行改性,并与壳聚糖复配共同对真丝织物进行抗皱整理,讨论了改性整理剂聚乙二醇(100)柠檬酸酯、壳聚糖和添加剂浓度,以及焙烘温度、时间等工艺因素对真丝织物抗皱效果的影响。试验证明,最佳整理工艺条件为:聚乙二醇(100)柠檬酸酯质量分数7%,壳聚糖质量分数0.3%,混合催化剂质量分数4%,三乙醇胺质量分数2%,渗透剂JFC质量浓度2 g/L,焙烘温度160 ℃,焙烘时间2 min。在此工艺条件下,聚乙二醇(100)柠檬酸酯-壳聚糖的协同整理效果明显优于柠檬酸,可替代2D树脂进行抗皱整理。

Abstract: Formaldehyde-free anti-crease finishing of silk fabrics has been a research concern for a long time. In this paper, polyethylene glycol(100) was used to modify citric acid, and it was compounded with chitosan for anti-crease finishing of silk fabrics. The impact of modified finishing agents polyethylene glycol(100) citrate, chitosan and additive concentrations, and the technological factors such as temperature and time on the anti-crease effect of silk fabrics were discussed. As proved by tests, the optimal finishing condition is as follows: polyethylene glycol(100) citrate concentration of 7%, chitosan concentration of 0.3%, mixed catalyst concentration of 4%, triethanolamine concentration of 2%, penetrant JFC concentration of 2 g/L, at the temperature of 160 ℃, baking time of 2 minutes. Under this process condition, the synergistic finishing effect of polyethylene glycol(100) citrate-chitosan was significantly better than that of citric acid. Thus, it can be used as a substitute of 2D resin for anti-crease finishing.

真絲织物手感柔软滑爽,光泽优雅柔和,花色丰富多彩,风格高端大气,是高档纺织品常用的面料之一。不足之处是真丝织物抗皱性比较差[1],洗后需熨烫才能保持其挺括、飘逸的外观。因此,真丝织物抗皱整理一直是研究的热点。传统抗皱整理剂如2D树脂类能显著提升真丝织物的抗皱效果,但服用过程中存在甲醛释放问题,危害人们身体健康。目前,无醛抗皱整理越来越受到研究者的重视。在无醛整理剂中,多元羧酸类研究较多,其中效果最好的是丁烷四羧酸。丁烷四羧酸是四元有机弱酸,经其整理后,真丝织物的弹性、白度、强力等可获得令人满意的效果。但是丁烷四羧酸因价格问题,限制了它的推广使用[2]。……
