新型天然染料在羊毛和蚕丝织物上的染色研究

为了扩大新型天然染料的来源、丰富天然染料的色相,采用洋葱皮、喇叭花、紫甘蓝、葡萄皮、紫米等新型天然染料对丝、毛织物进行了染色,并对其色牢度进行测试。结果表明:黄、紫洋葱皮与蛋白质纤维有着优良的亲和性,葡萄皮、喇叭花、紫米浸泡液、紫甘蓝与蛋白质纤维的亲和性低于洋葱皮,在媒染剂的作用下可以提高染色深度;紫甘蓝染料在蛋白质纤维上获得了蓝色相,紫洋葱皮、喇叭花染料获得绿色相;紫米浸泡液、葡萄皮染色获得了灰紫色相,弥补了天然染料色相的不足;所有织物干摩擦牢度较好,但湿摩擦牢度稍差,洋葱皮染料的耐日晒色牢度等级较高。

Development of new natural dyes for wool and silk fabrics

In order to develop new natural dyes and enrich the hue of natural dyes,onion,morning glory,purple cabbage,grape skin,black rice and other new natural dyes were selected to dye on silk and wool fabrics.After dyeing,the color fastness was evaluated.The results showed that the dyes from onion skins had a strong affinity for protein fibers.The dyes from grape skin,morning glory,black rice and purple cabbage had a poorer affinity for protein fibers than onion.The mordant can improve the depth of color.In the ex...
