锦纶和棉的染色性能不同,所以锦/棉交织物的同色性染色工艺较为复杂。传统的染色方法是采用分散/活性,分散/直接,酸性/活性等两浴法染色。本文用活性染料对锦/棉织物进行一浴两步法染色。选择pH值4.5-5可以对锦纶染色,在碱性条件下对锦纶不上色或轻微上色的活性染料,首先在酸性条件下对锦纶纤维染色,然后调节pH值到碱性对棉纤维染色,得到了优异的同色性。 相似文献

多组分纺织品是当前发展最迅速的一类纺织品,由于组分多,结构复杂,染色难度大,一般要选用两种染料染色。分散和活性两种染料是多组分纺织品染色的主要染料,它们分别用来染聚酯和纤维素纤维,后者还可染蛋白质纤维。这两种染料染色性能和工艺条件差异大,多半采用两浴法染多组分纺织品,染色工艺长,加工效率低,耗水耗能和污水排放量大。该文系统地介绍了分散和活性染料一浴法染色的难点和一浴法染色的思路,从理论上分析了一浴法染色的基础和途径,特别是对烟酸均三嗪染料的结构和性能,进行低破成中性固色的条件,以及和分散染料一浴法染色的近年进展作了深入的讨论,提出了一些新的染色思路,对开发此类染料,染色助剂和染色工艺有较好的参考价值,有利于一浴法生态染色。 相似文献

A series of temporarily solubilised reactive disperse dyes based on 1-substituted derivatives of 2-hydroxypyrid-6-one were applied to a 65;35 polyester/cotton blend using a one-bath dyeing method without dispersing agent. The dyeing behaviour of these dyes on polyester and cotton fabrics, and polyester/cotton blend fabric, were studied. The colour yields of the dyes on the polyester/cotton blend were found to be highly dependent on the initial pH, optimum results being obtained at pH 5. Good levelling and good to excellent fastness properties were obtained on the blend, with the exception of lightfastness, which was moderate. 相似文献

An alkaline dyeing of polyester with an alkali‐stable disperse dye, Dianix® Scarlet AD‐RG, was developed using sodium edetate as an alkaline buffering agent. The results obtained indicate the suitability of using sodium edetate for alkaline dyeing of polyester when compared with the control alkaline dyeing using Dianix AD system. Selected mono and bifunctional reactive dyes were used in combination with the alkali‐stable disperse dye for dyeing of polyester/cotton blend. Different dyeing methods for cotton and polyester/cotton blend fabrics using sodium edetate were evaluated in comparison with their respective control alkaline dyeing methods. The results of using sodium edetate in one‐bath two‐stage and two‐bath dyeing of polyester/cotton blend were comparable with that of the control dyeing method. Particularly, no change in the leveling and fastness properties was evaluated for all samples irrespective of the dyeing method. © 2007 Wiley Periodicals, Inc. J Appl Polym Sci, 2008 相似文献

以有机碱三乙醇胺为催化剂,邻苯二甲酸酐(简称苯酐)与自制阳离子改性剂WLS反应,制备苯酯助剂,并将其作为涤纶分散黑ECT染料常压染色的促染剂。通过系统研究,优化出苯酯合成工艺,并探讨苯酯助剂与N-正丁基邻苯二甲酰亚胺(简称亚胺)复配对分散黑ECT常压染色性能的影响。结果表明:苯酯与亚胺有很好的协同效应,二者质量比按2∶1复配时,可获得最佳染色效果。该复配促染剂应用于涤纶常压染色中,染色后织物先进行195℃焙烘2.5 min,再还原清洗,织物的染色深度K/S值和上染百分率较常压无助剂、同条件染色工艺显著提高,而且基本达到传统高温高压的染色效果。 相似文献

Phthalimide-based alkali-clearable azo disperse dyes were synthesised and applied to polyester and polyester/cotton blends. These dyes have an alkali-clearable property that enables alkaline treatment to be substituted for conventional reduction clearing. Therefore, by using these dyes, it is possible to avoid generating dyehouse effluents with high BOD values and carcinogenic aromatic amines that may, in some cases, be liberated by reduction clearing. In addition, polyester/cotton blends can be dyed by a one-bath, two-step dyeing method, as alkali clearability enables the disperse and reactive dyes to be used in the same bath. The dyeing behaviour and fastness properties of these dyes have been investigated. In particular, the cross-staining of cotton was studied to estimate the suitability of the dyes synthesised for dyeing polyester/cotton blends. 相似文献
