摘　　要：采用单因素分析法,考察了罗布麻茶染料用量、pH值、染色时间、染色浴比、染色温度对罗布麻茶天然染料染色羊毛织物K/S值的影响,然后采用Box-Behnken响应面设计法对罗布麻茶上染羊毛工艺进行了优化,探讨染色羊毛织物的色牢度以及罗布麻茶对羊毛织物的染色机理。结果表明,罗布麻茶上染羊毛织物最佳染色工艺为:染色温度100℃,浴比1∶30,染色时间80 min;染色织物的耐皂洗色牢度和耐摩擦色牢度等级达到4级;罗布麻茶成分中含有黄酮类化合物结构,通过氢键及离子偶合作用上染到羊毛织物上。This paper discussed the effects of dye dosage, pH value, dyeing time, dyeing bath ratio, and dyeing temperature on K/S values of apocynum venetum tea natural dye in dyeing wool fabrics. Then the dyeing process of apocynum venetum tea natural dye on wool fabrics was optimized using the Box-Behnken response surface design method. The color fastness of dyed wool fabrics and the dyeing mechanism were also discussed in the end of the paper. The results show that the optimized dyeing process for apocynum venetum tea natural dye on wool fabrics are that the dyeing temperature is 100 ℃, the bath ratio is 1∶30, and the dyeing time is 80 minutes.The washing fastness and rubbing fastness of dyed wool fabrics reaches grade 4. As there are flavonoid compounds in apocynum venetum tea natural dye, they can be dyed on wool fabrics through hydrogen bonding and ion coupling.
