摘　　要：采用荆芥色素提取液对蚕丝织物进行染色,讨论了染色pH值、温度、时间和荆芥提取液用量对蚕丝染色和抗紫外线性能的影响,测试了荆芥色素在蚕丝织物上的上染率、染色色深值、颜色特征值、UPF指数、紫外线透过率和染色牢度。结果表明,当荆芥提取液体积分数为50 mL/L时,荆芥色素直接染色蚕丝织物的最佳工艺为pH值2～3,染色温度90-100℃,保温染色60 min左右,染色蚕丝织物的耐洗、耐摩擦和耐日晒色牢度均达到3～4级以上,且染色蚕丝织物具有优良的抗紫外线性能,UPF值达45以上。Schizonepeta pigment is applied to silk fabric dyeing. The effects of dyeing liquor pH value, temperature, time and dyes dosage on dyeing and anti-UV performance of silk fabrics are researched. The dye uptake, color depth, color characteristics value, UPF, UV transmittance and color fastness of the dyed silk fabrics are tested. The results show that the optimum process for direct dyeing with schizonepeta pigment is pH value 2N3, dyeing at 90-100℃ for 60 rain with dye dosage 50 mL/L. The col- or fastnesses to washing, rubbing and sunlight can reach Grade 3-4, and the dyed silk fabric has excel- lent UV resistance, and the UPF value is above 45.
