Abstract

The theoretical tensile modulus of an ideal twisted yam was derived in the terms of mechanical values of its constituent fibers and yarn structural parameters by energy method. According to the theoretical results, the relative tensile modulus of yarn decreased with the increase of yarn's surface helix angle and the ratio of the fiber shear modulus to tensile modulus. Experimental data on twisted multi-filament yarns agree better with the predictions of this formula than those reported earlier in the literature.
