本文介绍了一种根据棉纤维上的直接、还原、冰染、活性和硫化染料在不同的溶剂中被萃取的程度不同而进行分类的简单方法。我们之所以选棉纤维上的染料为分析研究的对象，是因为棉纺织品深受人们的青睐，而且其上面的染料种类多，有些难以萃取。因而单根棉纤维上染料的萃取，分 This article presents a simple method for classifying cotton fibers based on their direct, reduced, ice-staining, activity, and the degree to which sulfur dyes are extracted in different solvents. The reason why we choose dyes on cotton fibers as the object of our analysis is that cotton textiles are favored by people, and the types of dyes on them are many and some are difficult to extract. Thus a single cotton fiber dye extraction, points
