摘要
研究了鱼腥草色素提取工艺及其提取液对真丝织物的直接染色工艺。结果表明鱼腥草最佳提取工艺为:NaOH质量浓度8g/L,提取温度100℃,提取时间50min,料液比1∶20。鱼腥草提取液对真丝织物直接染色的最佳工艺为:染色温度100℃,染色时间50min,染液pH值4.5,浴比1∶50。所染色真丝织物的耐摩擦牢度可达4级,而耐皂洗牢度相对较差。
The extracting process of Houttuynia cordata was studied. The direct dyeing process of silk fabric dyed with Houttuynia cordata extraction liquid was optimized. The results showed that the optimal extracting process of Houttuynia cordata was done at 100℃ for 50 min with NaOH 8 g/L, solid-liquid ration 1 ： 20. The optimal dyeing process of silk fabric was done at 100℃ for 50 min with pH value 4.5, bath ratio 1 ： 50. The rubbing fastness of silk fabric dyed with Houttuynia cordata extraction liquid was up to 4 grade, but the soaping color fastness was relatively poor.
