摘要
金盏花是一种植物染料,常作为食品上色剂。运用递推试验法和图表法,结合试验数据得出了金盏花色素最佳的提取条件和对真丝织物的最佳上染条件。重点介绍了金盏花色素对真丝织物的染色工艺,使用索氏提取器,结合丰富的提取剂、媒染剂及全面的染色方法,得出金盏花色素最佳提取试剂为石油醚与无水乙醇混比3∶2,最佳染色工艺为铝盐预媒染。试验结果表明,金盏花色素作为服装染料对真丝织物染色具有可行性。
As an ancient plant dye, the marigold is used as a food coloring agent. The optimal extraction conditions of marigold pigment and the best dyeing conditions of pure silk fabrics are obtained by using the experiment method and the chart method. The marigold pigment dyeing process of real silk fabrics is introduced. By using soxhlet extractor combined with rich extraction agent, mordant and comprehensive dyeing method, the optimum marigold pigment extraction reagent is petroleum ether and ethanol solution with the blending ratio of 3 ： 2, and the optimum dyeing process is pre-mordant dyeing with aluminum salt. The results show that the marigold yellow pigment is feasible as a garment dye for silk dyeing.
