短纤维强力的概率分布分析

纤维强力对于纱线乃至织物来说都是一个重要的性能，而纤维的强力有一定分布。这里对羊毛、绢丝、棉、亚麻、腈纶、涤纶、芳纶、玻璃纤维、碳纤维等9种纤维的强力进行了测试和统计分布拟合。发现棉、腈纶、涤纶、芳纶和碳纤维的强力严格符合二参数的Weibull分布，而羊毛、绢丝的强力则符合三参数的Weibull分布，而亚麻的强力用两种

Strength Distribution Analysis of Staple Fibers

The strength of staple fibers is an important property for yarns and fabrics. Usually there are variations in individual fiber strength, and this will affect the final strength of yarns and fabrics. In this study, Weibull distribution function is used to analyze the strength distribution of various staple fibers. The strengths of wool, silk, cotton, flax, acrylic, polyester, glass, aramid and carbon fiber are tested. It is found that the strengths of cotton, polyester, glass, aramid and carbon fiber agree well with the twofactor Weibull distribution, while the strengths of wool and silk agree the three-factor Weibull distribution. However, the strength distribution of flax can not be expressed by either two-or three-factor Weibull distribution covincingly.
