【摘要】 茜草作为特殊的传统天然染料，在染色文化史上占有重要地位。在研究日本《农业全书》中的茜草染工艺基础上，结合日本《延喜式》中的相关用料配比，通过反复实践，确定茜草色素优化萃取染色工艺为：萃取时间30min，萃取温度90℃，染色时间20 min，染色温度50～70℃，媒染时间20 min，媒染温度为常温，食醋用量为染液量的10%左右。研究认为，茜草染工艺绿色环保，所染丝绸色彩鲜艳、色牢度高，在当代纺织服装、纤维艺术等领域仍然具有广阔的开发应用前景。更多还原

【Abstract】 As a special traditional natural dye, madder plays an important role in the history of dyeing cultural. On the basis of studying the dyeing technology of madder in Agricultural Encyclopedia of Japan and combining with the relevant material ratios in Engishiki, through repeated practice, the optimal extraction and dyeing process of madder pigment is as follows: extraction time 30 min, extraction temperature 90 ℃, dyeing time 20 min, dyeing temperature 50-70 ℃, mordant dyeing time 20 min, mordant dyeing temperature room temperature, with vinegar added at approximately 10%(on the mass of dyeing solution). Research suggests that the madder dyeing technology is green and environmentally friendly, and the dyed silk has bright colors and high color fastness. It still has broad development and application prospects in multiple fields such as contemporary textiles and clothing, fiber art and etc.更多还原
