    • Abstract:
      The extraction of active substances and other nutrient elements from Lycium barbarum and their application in food, medicine, and cosmetics have always been one of the hot topics for scholars in related fields. However, the residue after the extraction still contains melanoidin, which is an important substance that can be used as an environmentally friendly pigment in the coloring of textiles. Therefore, the rational utilization of the by-products after the processing of Lycium barbarum is the key to sustainable development. For this reason, Lycium barbarum residue was used as the raw material to extract textile-grade dyestuff in this work. The phospholipid microcapsules dyeing process of melanoidin dyestuff from Lycium barbarum residue was optimized by the response surface optimization as follows: liquor ratio of 1:35.15, pH of 4.22 and dyeing temperature of 75.8°C. The results showed that the dyeing temperature reduced by 15°C during the dyeing process by using melanoidins microcapsules dyestuff. Dyed wool fabric with biomordant (pomegranate skin) and after-chrome dyeing has high color fastness, antioxidant, and antibacterial property, which greatly increases the added value of the dyed products.

    • Abstract:
      从枸杞中提取活性物质和其他营养元素及其在食品、医药和化妆品中的应 用一直是相关领域学者的热门话题之一. 然而, 提取后的残留物仍然含有类 黑素, 类黑素是一种重要的物质, 可以用作纺织品着色中的环保染料. 因此, 枸杞加工后副产品的合理利用是枸杞可持续发展的关键. 为此, 本研究以枸 杞渣为原料提取纺织级染料. 采用响应面优化法, 优化了枸杞渣类黑素染料 磷脂微胶囊的染色工艺:液比为1:35.15, pH值为4.22, 染色温度为75.8°C. 结 果表明, 类黑素微胶囊染料在染色过程中染色温度降低了15°C. 用生物媒染 剂（石榴皮）进行后媒染色的羊毛织物具有较高的色牢度、抗氧化和抗菌 性能, 大大提高了染色产品的附加值.
