ABSTRACT

With the aim of introducing a new source of natural dye and developing a sustainable coloration process, the dyeing of wool with the leaves of Berberis thunbergii DC was optimized using response surface methodology. The results showed that increasing the dye concentration and dyebath temperature increased the color strength (K/S) and increasing the dyebath pH and mordant concentration decreased the K/S. The optimum pH, dye concentration, dyeing temperature, and mordant concentration for obtaining the highest K/S were 5, 146%owf, 76°C, and 3.8%owf, respectively. The sample dyed under the optimal conditions showed good color fastness properties.

小檗 DC 叶作为天然染料新来源的羊毛染色 RSM 优化

摘要

为了引入一种新的天然染料来源并开发可持续的着色工艺，使用响应面法优化了用小檗树叶对羊毛的染色。结果表明，增加染料浓度和染浴温度会增加染色强度（K/S），增加染浴pH和媒染剂浓度会降低K/S。获得最高 K/S 的最佳 pH 值、染料浓度、染色温度和媒染剂浓度分别为 5、146%owf、76°C 和 3.8%owf。在最佳条件下染色的样品显示出良好的色牢度性能。
