Usually there are variations in individual fiber strength, and this will affect the finai strength of yarns and fabrics. In this study, Weibuli 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 fit well with the two-factor Weibull distribution, while those of wool and silk with the three-factor Weibuil distribution. However, the strength distribution of flax cannot be expressed by either two- or three-factor Weibull distribution convincingly.展开更多
