Abstract: In order to reduce work intensity for the fiber composition inspection of cotton and ramie content， the authors studied the linear relationship between the colorimetry parameter data and the content of cotton and ramie according to trichromatic staining method. It is concluded that the linear relationship between the data of chromaticity coordinates x and the cotton content is good. So the trichromatic staining method was set up for determining the blended ratio of cotton and ramie. The standard method of micro-projection method is used as a comparison method， and their results are very similar. Thus the established method can meet the requirements for rapidly determining the blend ratio of cotton and ramie in fiber.
