摘要

像棉和麻这样的纤维素材料是用活性染料和直接染料染色的优良纺织基材。由于其纤维素性质,棉和麻对直接染料和活性染料表现出良好的亲和力。这种良好的亲和力是良好的洗涤和摩擦牢度的原因。壳聚糖是由几丁质脱乙酰得到的生物基聚合物。与纤维素不同,壳聚糖也含有氨基官能团。研究了壳聚糖预处理棉麻织物的染色性能。经不同壳聚糖预处理后,采用CIEL*a*b*指数测定其颜色性能。测定了干燥和潮湿条件下的摩擦牢度。即使在实际研究中没有确定壳聚糖预处理的积极作用,确定的结果也可以在未来的研究中利用实施壳聚糖开发棉麻材料的其他功能处理。

Evaluation of chitosan based pretreatment for cotton and linen dyeing with direct dyes and reactive dyes
Cellulosic materials like cotton and linen are excellent textile substrates for dyeing with reactive and direct dyes. Due to their cellulosic nature, cotton and linen exhibit good affinity towards direct and reactive dyes. This good affinity is the reason for good washing and rubbing fastness. Chitosan is a bio-based polymer gained by the deacetylation of chitin. In contrast to cellulose, chitosan exhibits also amino functional groups. The purpose of this paper is to evaluate if a chitosan based pretreatment of cotton and linen can lead to different dyeing properties. After different chitosan based pretreatments, the color properties are determined by CIEL*a*b* indices. The rubbing fastness in dry and wet conditions is measured. Even if in the actual study no positive effects were determined by pretreatment of chitosan, the determined results could be utilized in future research to develop other functional treatments of cotton and linen materials with implemented chitosan.
