Four poly-functional reactive dyes keeping mono or bis reactive group have been synthesized and applied successfully to cotton fabric. The main target of study was to synthesize novel reactive dyes having multiple reactive cites to show maximum colour strength. In order to explore the best dyeing conditions, dyeing parameters such as dyeing time, temperature and pH of dyeing bath as well as salt concentration were optimized. Textile printing is the most versatile method used for introducing varieties of design to textile fabrics. These synthesized dyes were applied to fabric for evaluating their printing potential. Fastness properties such as washing, light, rubbing, dry cleaning and perspiration were also investigated after application by exhaust method and printing techniques at Noor Fatima Textile Industry (Pvt.), Faisalabad, Pakistan. The percentage dye exhaustion and fixation was found to be reasonably good and acceptable. All the dyes, after fixation onto the fabrics, showed moderate to excellent fastness properties and colour strengths. The prints of these reactive dyes also demonstrated equitably good colour fixation and fastness characteristics.
我们合成了四种含有单或双活性基团的多功能活性染料,并成功地应用于棉织物。研究的主要目标是合成具有多个活性基团的新型活性染料,以显示最大的染色强度。为了探索最佳染色条件,对染色时间、染浴温度和 pH 值以及盐浓度等染色参数进行了优化。纺织品印花是最通用的方法,可将各种设计引入纺织面料。这些合成染料被应用于织物,以评估其印花潜力。在巴基斯坦费萨拉巴德的努尔-法蒂玛纺织工业公司(Noor Fatima Textile Industry (Pvt.)),我们还通过排气法和印花技术研究了织物的耐洗、耐光、耐摩擦、耐干洗和耐汗渍等牢度特性。结果表明,染料耗尽和固着的百分比相当好,可以接受。所有染料固着在织物上后,都显示出中等到优异的牢度特性和色彩强度。这些活性染料的印花也同样表现出良好的固色和牢度特性。
