Strength Distribution Analysis of Typical Staple Fibers

IntroductionThe mechanical properties of yarns are deter mined bytheir constituent fibers.Consequently,the strength offibers is an i mportant property in deter mining the finalquality of all textile products.Generally,it is al ways truethat the higher the strength of fibers,the higher thestrength of yarns and fabrics.However,because of the variation of fiber strength,the fibers within a yarn will not break at the same ti meunder a tensile load.In fact,break will take place at theweakest fiber…

Strength Distribution Analysis of Typical Staple Fibers

The strength of staple fiber is an important property for yams and fabrics. 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.
