纱线染色经验两则

一、分散染料化料方法对纱线染色质量的影响我厂是生产缝纫线的专业工厂,在生产涤纶缝纫线的初期,曾出现过一些染色质量问题。经过几年的生产实践,感到有些问题是由于化料方法不当而造成的。下面介绍的是我们现在的一些做法,以供同行参考。1.水温:分散染料的化料水温直接影响到染料的溶解程度。我们有一段时间一律使用60℃水化料,现在看来是不够妥当的。一般品种,如分散黄RGFL、分散蓝2BLN、分散灰N、分散黑S-3BL等可使用60℃水化料。有些品种,如分散红玉S-2GPL Foron大红S-3G     

实用染色的若干应用技术(十八)

Q&A 问:高温型分散染料能用载体法染涤纶吗? 答:对于涤毛、涤锦、涤腈和涤氨等混纺交织物以及"三合一"、"四合一"等含涤纶产品,本该根据各种纤维的特性,选用相应的染料和工艺采取条染进行染色加工,以减少互相沾色,提高色牢度.涤纶应采用高温高压染色,而许多含涤纶织物中又含有不耐高温的纤维,因此只能采用载体法对涤纶染色.当然,选用的载体应该是环保型的最适应载体法染色的是小相对分子质量的低温型分散染料,然而该类染料色谱不全,而常用的如分散深蓝H-GL、翠蓝S-GL、红玉S-2GFL、紫HFRL、大红S-G、S-BWFL和嫩黄S-4GL等均系高温型染料.实践证明,选择高温型分散染料染涤纶,不仅价格低廉,色谱齐全,而且色牢度,尤其是升华牢度比低温型好(表1).

壬基酚聚氧乙烯醚琥珀酸二酯磺酸钠的合成及染色应用

以烷基酚聚氧乙烯醚、马来酸酐和亚硫酸氢钠为主要反应物,采用超声-微波协同技术合成了烷基酚聚氧乙烯醚型磺基琥珀酸二酯钠盐Gemini表面活性剂,并用FT-IR和1H-NMR对产物结构进行表征。将其应用于毛/涤混纺织物分散染料的一浴法染色。探讨了p H、浴比、温度和NS用量对染色效果的影响,毛/涤混纺织物分散染料一浴法染色最佳染色工艺条件为:染液p H=3~4,浴比=25∶1,w(NS)=3%(owf),染色温度为95℃。在此工艺条件下,分散橙30、分散蓝2BW、分散红73和分散红SE-F3B的染色效果均有提升,且色牢度达4级以上。在染色体系中添加NS可以降低染色温度,显著提高分散染料的上染率。

低聚物对聚酯织物分散染料染色废液COD_(Cr)的影响

采用原位聚合法在不同芯壁比条件下对纯分散染料进行微胶囊化,将其对溶剂萃取过低聚物的TTT及PET织物进行染色,采用紫外分光光度法测定染色废液CODCr值,并与相应的商品分散染料染色废液CODCr值进行比较.结果表明,低聚物的存在将增大PTT及PET织物染色废液的CODCr值;对于相同分散染料,芯壁比为1:2的微胶囊染色废液CODCr值大于芯壁比为1:4的微胶囊染色废液CODCr值;微胶囊分散染料染色废液CODCr值远低于相应商品分散染料的染色废液CODCr值.

Optimal dyeing systems for resistance to the physical strength loss of the PLA/cotton blended fabric

In this study, optimization of disperse/reactive dyeing systems for resistance to the physical strength loss of Poly(lactic acid) (PLA)/cotton blended fabric was investigated. The blended fabric underwent a two‐bath, two‐stage dyeing process in which the PLA component of the blended fabric was dyed using two disperse dyes, followed by the cotton component being dyed with six reactive dyes containing different reactive groups—dichlorotriazine, monochlorotriazine, sulphatoethylsulphone, monofluorotriazine, monochlorotriazine/sulphatoethylsulphone, and monofluorotriazine/sulphatoethylsulphone groups. The optimal dyeing systems were established according to the fixation rate of the dyes, tear/tensile strength loss, and SEM micrographs of the fabric. To avoid the strength loss during the disperse/reactive dyeing process, the recommended disperse dyeing conditions were 110°C, pH 5 for 20 min, whereas the reactive dyeing conditions should be temperature ≤60°C and alkali concentration ≤3 g/L. In this regard, reactive dyes containing monofluorotriazine and monofluorotriazine/sulphatoethylsulphone groups were especially suitable for the reactive dyeing systems. © 2010 Wiley Periodicals, Inc.

A novel and eco-friendly approach for dyeing polyester fabrics by liquid disperse dyes treated with deep eutectic solvent

Disperse dyes do not contain water-soluble groups and are difficult to dissolve in water, so they cannot be directly formulated into dyeing liquor. In the current dyeing process, the solubility of disperse dyes is mainly improved by adding dispersants. However, dispersants are not absorbed by fibres and survive in the dyeing effluent, aggravating the pollution of water bodies and causing difficulties in treatment. Therefore, the development of a novel, eco-friendly dyeing approach is important to overcome these problems. Herein, for the purpose of improving the solubility of disperse dyes and reducing the dosage of dispersants, a deep eutectic solvent consisting of choline chloride/ethylene glycol was employed instead of dispersant to dissolve CI Disperse Blue 79 and CI Disperse Red 343, thus forming liquid disperse dyes. The results show that both CI Disperse Blue 79 and CI Disperse Red 343 were well dissolved in choline chloride/ethylene glycol with excellent stability, and the dissolution behaviour was strongly associated with the dissolution temperature and time. Moreover, polyester fabrics can be dyed successfully with liquid disperse dyes, and it was observed that the K/S value and rubbing fastness were evidently improved at the same dyeing temperature with unchanged colour characteristics, and a higher K/S value could still be obtained by lowering the dyeing temperature. This work establishes a green dyeing process, which reduces dyeing costs and meets the demand for environmental protection. It is also expected to realise the liquid state of disperse dyes, which will help to promote the further development of textile dyeing.
