Conclusions
A quantitative characterization of nonsimultaneity in failure of the elementary filaments in a complex yarn on the right-hand part of the stretching diagram has been given.
Some features of the failure of elementary filaments in a complex yarn at various sample clamped lengths have been examined.
A method has been proposed for evaluating nonuniformity in breaking characteristics of elementary filaments in a complex yarn from the right-hand part of the stretching diagram at a low clamped length, and also from the ratio of the works of deformation to maximum loading and to complete yarn failure.
