一、前言随着内衣外衣化,涤/棉绒布、汗布、网眼布的生产日益增加,特别是浅色涤/棉T恤衫色彩明朗,自然洒脱,更是受人青睐。1988年初,我厂接受的涤/棉网眼布的外贸产品,浅色品种占75%。在保证染色质量的前提下,如何缩短工艺,提高经济效益是我厂染色工作者的任务。下面谈谈关于浅色涤/棉针织物的染色。二、浅色涤/棉针织物染色方法试探涤纶针织物由于纤维及染料的物理化学性质决定,一般是用高温高压方法染色。在常压下的沸点温度染色,纤维分子开始产生热运动,分子间空隙增大。与此同时,分散染料的溶解度也大为增加,尤其是普通型的分散染料,由于分子量小,更容易进入涤纶纤维内部。尽管在常压下染色饱和量较小,但由 相似文献

Dyeing natural fibres in supercritical carbon dioxide using a nonionic surfactant reverse micellar system 总被引:2,自引:0,他引:2
A reverse micellar system in supercritical carbon dioxide has been developed as a dyeing medium. Water-soluble dyes such as reactive dyes and acid dyes could be sufficiently solubilised in the interior of a specially constituted reverse micelle. Protein fabrics, silk and wool, were satisfactorily dyed even in deep shades with conventional acid dyes without any special pretreatment. Cotton cellulose fabric was also dyed with conventional reactive dyes when the electrostatic force of repulsion between dye and cotton was eliminated. Compared to previously proposed supercritical dyeing methods, dyeing of fabrics with this system could be performed at low temperatures and pressures in a short time. 相似文献

The aim of this study was verification of the effect on the dyeing process of using microencapsulated forms of textile dyes and a textile auxiliary agent. Anionic dyes and ammonium sulphate were microencapsulated into the liposomic systems. Prepared liposomes were used for the dyeing of polyamide knitted goods. The ability of these microencapsulated forms to improve the uniformity of polyamide knitted goods dyeing was confirmed. This finding could be applied to the dyeing of polyamide substrates on an industrial scale, especially as the described process of microencapsulation is straightforward and could be performed in an industrial environment. 相似文献

锦纶66微纤维活性染料染色条件探讨 总被引:3,自引:0,他引:3
采用毛用和棉用活性染料对锦纶66微纤维染色,详细讨论了染色温度、染浴pH值、染色和皂洗方法对染色深度和固色率的影响,分析了不同类型的活性染料对染色条件的敏感性。活性染料对锦纶66微纤维的染色深度、固着率和固着效率受温度、pH值、染料母体结构和活性基的影响很大。毛用活性染料更适合于锦纶66微纤维的染色,普通乙烯砜硫酸酯及乙烯砜硫酸酯/一氯均三嗪染料可有选择性地加以使用,毛用活性染料合适的染色pH值约为4,其它染料适用的pH值因品种而异。采用酸性染色或先酸性后碱性的染色条件均可,后者的优点是固着效率高,但染色深度未见提高染色后采用碱性条件皂洗有利于染色深度的提高。 相似文献
