Research on the Development of High-Quality Hemp Fiber
Different varieties of hemp (Canabis sativa L.) are cultivated in many regions in China for the production of hemp plant fiber. The objective of this study was to evaluate differences in the growth cycle, yield, quality of fiber and spinnability among the different varieties. We analyzed and compared the yield, fiber percentage, chemical components, breaking strength and spinnability, which determines fiber combing yield and fineness, of different hemp fiber from eight C. sativa varieties (Longjiang 1#, USO-14, Yun-hemp 1#, Shandong hemp, Qingshui hemp, Ningxia 6757, Ningxia 6762, and USO-31). We analyzed the data with a gray near-optimized method to select the variety of hemp that gave the best quality of fiber and was, therefore, the most suitable for cultivation in Heilongjiang Province. The results identified Longjiang 1# as the most suitable variety, USO-14 is the next best, and Yun-hemp 1# as the least suitable.
