| Abstract: | The tensile properties of spun yarns decisively influence its performance in various mechanical processing stages. This study
is primarily aimed at simultaneous analysis of two tensile properties of spun yarns namely tenacity and breaking strain, which
play crucial role in determining the frequency of warping breaks. The threshold values of yarn tenacity and breaking strain
required for 20’s Ne carded cotton yarn to sustain the imposed stresses and strains during warping process have been determined
using a bivariate normal distribution model. This study opens up the possibility of minimizing end breakage rate in various
manufacturing processes of textile industry by engineering of spun yarns devoid of potential weak spots which are responsible
for breaks. |
