摘　　要：提取黄连染料用于真丝绸的轧染,研究了轧染p H值、轧染次数、固色工艺方法及媒染剂对染色性能的影响,测试了染色织物的抗紫外线性能。结果表明,黄连轧染真丝绸的适宜工艺为:p H=8,轧染4次,单宁酸为媒染剂;汽蒸工艺和冷轧堆工艺可较焙烘工艺获得更高的染色深度及牢度。在适宜条件下,黄连轧染真丝绸的摩擦牢度可达到3级,但皂洗牢度较差,仅为2级。经黄连染料轧染后,真丝绸的紫外线透过率显著降低,UPF值由整理前的3.78提高到43.56,具有优异的紫外线防护性能。Coptis chinensis colorant is extracted and used for pad dyeing of silk fabric. The influences of pH value, padding cycles, fixing process and mordant agent on dyeing results of silk fabric are studied. The pad dyeing process of silk fabric is optimized as follows： tannic acid as the mordant, pH=8, 4 pading cycles. Silk fabric treated with steaming process or cold pad-batch process features higher color strength and color fastness than that with the curing process. The color fastness to rubbing of coptis chi- nensis dyeings can reach Grade 3, while the color fastness to soaping is only about Grade 2. The UV transmissibilitv of silk dveings decreases sifilnificantlv with increased UPFvalue from 3.78 to 43.56.
