Three vinylsulfone based poly anchor reactive dyes have been synthesized by following condensation, diazotization and coupling reactions respectively, with a view to achieve bright shades and good fastness properties. Cotton fabric was desized, bleached and mercerized before dyeing and application studies. Pad-thermosol dyeing method was employed since it is more environment friendly due to high dye fixation. Effect of different dyeing parameters i.e. salt concentration, dyeing time, dyeing temperature and pH of dye solution were optimized. The dyed fabrics were subjected to CIE LAB and LCH system in order to evaluate the dyeing quality parameters by using Spectraflash SF-600 at Noor Fatima Textile Pvt. Ltd., Faisalabad. Fastness properties such as perspiration, light, washing, chlorinated water, dry cleaning and crocking were evaluated for the dyed fabrics by following ISO standard test methods.
分别通过缩合、重氮化和偶联反应合成了三种乙烯基砜基聚锚定活性染料,以期获得明亮的色调和良好的牢度性能。棉织物在染色和应用研究之前经过退浆、漂白和丝光处理。采用热浸轧染色法,由于染料固着率高,更加环保。优化了不同染色参数(即盐浓度、染色时间、染色温度和染料溶液 pH 值)的效果。染色织物经过 CIE LAB 和 LCH 系统测试,以便使用 Noor Fatima Textile Pvt. 的 Spectraflash SF-600 评估染色质量参数。有限公司,费萨拉巴德。根据 ISO 标准测试方法,对染色织物的耐汗、耐光、耐洗涤、氯化水、干洗和摩擦等牢度性能进行评估。
