Abstract : Strain-wave propagation is proposed as the mechanism which accounts for the occurrence of multiple tensile breaks in textile fibers. The breaks are uniformly distributed along the central portion of the test length with a higher concentration existing at or near the boundaries (i.e. the tabs). The region of uniform distribution results from initial random breaks while the high concentrations at the ends are due to reflections of energy waves. Recoverable energy stored in the fiber during extension is the driving force for wave propagation. The dependence of multiple breaks on testing length, rate of extension, temperature, medium, morphology, and tenacity at break is discussed. (Author)
