摘　　要：对橘皮色素进行了提取与光谱测定基本试验,依据色浓度与色光变化情况,确定了其最佳提取剂为无水乙醇和蒸馏水。橘皮色素的最大吸收波长为400 nm。采取直接法和媒染法研究了橘皮色素对蚕丝纤维的上染情况,对其上染率和染色牢度进行了测定和结果分析,确定了直接染色与媒染染色的最佳染色工艺分别为:直接法用色素原液染色,浴比1∶50,pH值6,90℃,60 min;用铝和铁媒染剂处理的染色工艺为:铝媒染剂6%(owf),铁媒染剂4%(owf),温度均为60℃,重复3次;染后织物各项牢度较好。The resources of orange peels are abundant but are underutilized.This paper makes the basic experiments on abstraction and spectrometric determination for pigments from orange peels and determines the optimal extractants to be absolute ethanol and distilled water based on the changes of color concentrations and chromatic light.The longest absorption wavelength of pigments from orange peels is 400nm.The paper adopts the direct and mordant methods to study the dyeing of pigments from orange peel for silk fibers and makes the determination and analysis for the dye uptake rate and color fastness.The optimal dyeing processes of direct and mordant methods are that stock solution of pigments is used in the direct method with the liquor ratio of 1∶ 50,pH value 6,90 ℃,60 min,The conclusion which can be drawn with the aluminum and iron dyeing mordants is that the concentration of aluminum dyeing mordant is 6%（owf）,the concentration of aluminum dyeing mordant is 4%（owf） and the temperature is 60 ℃ and the fastness of the dyed fabrics is satisfactory to some extent.
