Influence of carding on hemp length/fineness

Hemp has become popular in the study of natural fibers as its excellent ecological properties. In the article, degummed hemp was carded with cashmere carding machine. The fineness and length of degummed hemp, carded hemp and noil hemp were tested and the test data was statistically analyzed. The result showed that the fineness of hemp improved 15. 3% after carding, and the evenness of fineness decreased 46.5% ; the average length of hemp decreased 1.6%, but the evenness of length improved 13.8%. The effect of removing coarse fibers by carding with cashmere carding machine was good, the evenness of length and fineness were both deceased largely, and it provided a basis for developing hemp/cashmere blending yarns or fabrics.
