摘  要：为减少纤维成分棉麻含量检验工作的强度，通过三原色染色法，研究三原色染色棉麻纤维的色度学参数数据与棉麻含量的线性关系，得出色度坐标x的数据与棉含量的线性关系较好。建立三原色染色法测定棉麻混纺比的方法，与标准法显微投影法进行比对，结果非常相近，满足快速测定棉麻纤维混纺比的要求。

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.
