摘　　要：测定了阳光、温度、洗衣粉和金属离子等因素对棕色棉纤维稳定性的影响,并分析了不同pH和不同浓度的纯化色素水溶液色彩的特性,观察纯化色素液与金属离子反应,来探索彩棉棕色素的稳定性机理。实验发现棕色棉纤维色调值位于38度,饱和度为29%,亮度为53%,探明了阳光、温度、洗衣粉和金属离子等因素对棕色棉纤维色彩均产生影响以及pH和浓度对纯化色素的色彩产生影响的规律。The effects of sunshine, temperature, washing power and metallic ions on the natural brown cotton fiber were determined, and the mechanism of the effects was analyzed by studying the color turning of different densities or pH values aqueous solution of the natural brown cotton pigment, and by observing the chemical reactions of the pigment and metallic ions in the paper. Found out： the color traits of the natural brown cotton fiber, hue are located at 38 degree, saturation 29 % , and lightness 53 %. The factors such as sunshine, temperature, washing power and metallic ions influenced the color characteristics of the natural brown cotton fiber. The values of pH and the densities of the pigment affected the color properties of the pigment aqueous solution.
