Neps contribute maximum towards imperfections in comparison to thick and thin places. Though the tenacity values of brin are almost similar for all the yarns, the changes occur when the brins are converted into yarn. The yarns are more extensible than brins. The modulii of the brins are always higher than those of the corresponding yarns. All tasar yarns show rectangular cross-section of brin.</span></span></span>
