摘　　要：通过提取和测试天然彩色棉的色素,结果表明,天然色素系水溶性或醇溶性多酚类物质,具2苯基苯并吡喃的结构;酸碱联合反应试验显示,天然色素遇酸碱易变色;色素中含有可剥离色素,应采用中性洗涤剂。Experiments are undergone to extract colorants from naturally colored cotton fiber. Results show that natural colorants are water or alcohol soluble substances with 2-benzyl benzofuran structure. Combined reaction with alkali and acid proves that natural colorants will result in color change when reacted with alkali or acid. Separable colorants are removable with neutral detergents.
