摘要
为改善1,4-萘醌天然染料对棉织物的染色性能,采用柠檬酸与酒石酸复配进行交联染色。采用扫描电镜、红外光谱分析了染色前后棉织物的结构,探讨了染色前后棉织物的染色性能和物理性能以及染色机理。结果表明,交联染色后,1,4-萘醌天然染料通过酯键固着在织物上,棉织物表面变得粗糙。与1,4-萘醌天然染料直接染色样品相比,采用柠檬酸和酒石酸复配交联染色后染品的上染率和染色深度(K/S)分别提高了21%和83%,匀染性良好,染品的黄光增加,颜色饱和度提高,摩擦牢度提高了1~3级,耐洗色牢度提高了1~2级,抗皱性能大约提高了50%,水接触角提高了11%。
To improve the dyeing properties of 1,4-naphthoquinone natural dye on cotton fabrics, a mixture of citric acid and tartaric acid was used for crosslinking dyeing. The structure of cotton fabrics before and after dyeing was analyzed by SEM and FTIR. The dyeing properties, physical properties and dyeing mechanism of cotton fabrics before and after dyeing were discussed. The results showed that 1, 4-naphthoquinone natural dye was bonded to the fabrics by ester bonds, and the surface of cotton fabrics became rough after crosslinking dyeing. Compared with those of the direct dyeing cotton fabrics, the dyeing rate and dyeing depth(K/S) of the crosslinking dyeing cotton fabrics with the mixture of citric acid and tartaric acid were increased by 21% and 83%, respectively. The good levelness property was obtained. At the same time, the yellow light and color saturation of the dyed product increased, the rubbing fastness increased by about 1~3 levels,and the washing fastness increased by about 1~2 levels, the crease resistance was enhanced by about 50%,and the water contact angle was increased by 11%.
