An innovative explanation of spun yarn failure mechanism has been
proposed which has validity in explaining some of the anomalies
encountered in the previous literatures. A novel mathematical model
of yarn tenacity has been derived which can predict the strength of
spun yarns produced by any spinning technology. The proposed model
of yarn tenacity generates a reasonable agreement between the
predicted and measured values of yarn tenacity and it provides a
better understanding of the mechanism of failure process of spun
yarns. Using the Weibull distribution parameters of yarn tenacity
at a particular gauge length and the classical weakest-link scaling
theorem the yarn tenacities at other gauge lengths were predicted.
The mechanics of failure of various spun yarns were critically
analyzed from the investigations of yarn structure, length of
failure zone and percentage broken and slipped fibres. The failure
behaviors of spun yarns at different gauge length and extension
rate were investigated in details. The effect of strain rates and
gauge lengths on the characteristics of the stress-strain curves of
different spun yarns was also studied.
