【摘要】 采用特殊订制的分散染料对锦纶丝袜进行超临界二氧化碳染色。试验结果显示:通过控制温度、压力和时间,能够利用超临界二氧化碳流体对锦纶丝袜进行去油、溶胀和染色并注入共溶剂,最终获得染色效果均匀、得色率和色牢度高的染色产品。染色结果证实:进行锦纶丝袜超临界二氧化碳全流程无水环保染色可行且具有良好的应用前景。更多还原

【Abstract】 The paper discusses the dyeing of stockings made from spandex/nylon core yarns in supercritical carbon dioxide fluid(SCF)with disperse dye that is affinitive to both components of the yans.Dyeing result shows SCF functions well as a detergent in the stockings’ pre-dyeing treatment including oil cleaning and preshrinking,and as a medium able to dissolve the dye and levelly add color ontothe stockings at a relatively high yield with a given color fastness under the proper control of dyeing temperature,pressure and time.Color yield and fastness are subject to the dye applied.Color fastness can also be improved by removing unfixed dye from the stockings using SCF.The SCF dyeing method,which is water-free and environmental-friendly,is applicable and presents a good prospect in the dyeing of stockings spandex/nylon core yarns.更多还原
