摘　　要：根据《GB/T 14337-2008化学纤维短纤维拉伸性能试验方法》,重点分析夹持距离对聚乙烯醇、丙纶及腈纶纤维伸长率、断裂强力、抗拉强度及弹性模量的影响。结果表明:夹距对短化纤的断裂强力和抗拉伸强度没有明显的影响,而夹距越大,短化纤的断裂伸长率越小,初始弹性模量越大。Based on GB/T 14337 -2008 testing method for tensile prosperities of man-made staple fibers, the effect of clip distance on single staple fiber＇ s elongation percentage, breaking strength, tensile strength and e- lastic modulus was analyzed emphatically. The results found that there is little effect of clip distance on break- ing strength and tensile strength, while, the larger the clip distance, the smaller the elongation percentage and the bigger the initial elastic modulus of staple fiber.
