Abstract

Due to growing environmental concerns, the research on coloration of textiles with reactive dyes is gaining special attention nowadays because of their maximum usage, excellent wet fastness and friendliness. One disadvantage of reactive dye is the hydrolysis, due to which a large amount of dye does not fix the fabric leading to extensive washing. The present study deals with increasing dyeability and functionality of cotton reactive dyeing using chitosan. In conventional reactive dyeing method, salt and alkali’s concentration are more used generating effluent, which is harmful for marine life, crops and also for human health. For overcoming this problem, we have used a chemical name as chitosan due to which concentration of salt and alkali will be reduced. Different reactive dyes were applied on woven fabric pretreated with chitosan and comparison was made. Colorfastness properties like rubbing, washing and light fastness of untreated and treated dyed fabric samples were measured using AATCC 08, AATCC 61 (2A) and AATCC 16, respectively. The color strength of these dyed fabric samples was determined by K/S value for comparison.

摘要

由于对环境的日益关注，活性染料对纺织品着色的研究由于其最大的使用量、优异的湿牢度和友好性而在当今受到特别关注。活性染料的一个缺点是水解，因此大量染料不能固定织物，导致大量洗涤。本研究涉及使用壳聚糖提高棉活性染色的可染性和功能性。传统的活性染色方法中，更多地使用盐和碱的浓度，产生废水，对海洋生物、作物和人体健康有害。为了克服这个问题，我们使用了一个化学名称作为壳聚糖，因为它会降低盐和碱的浓度。将不同的活性染料应用于壳聚糖预处理的机织物上并进行比较。分别使用 AATCC 08、AATCC 61 (2A) 和 AATCC 16 测量未处理和处理过的染色织物样品的色牢度特性，如摩擦牢度、洗涤牢度和耐光牢度。这些染色织物样品的颜色强度由 K/S 值确定以进行比较。
