Abstract: The influence of twisting method on the properties of Ne 39/1 and Ne 26/1 combed cotton yarns, plied two and three times on ring, two-For-one and balloonless twisting machines, has been studied. The yarn tenacity, breaking extension, work of rupture, twisting variations, hairiness (S3) and hairiness index values of the resultant yarns have been evaluated. The results, evaluated statistically, show that the plying and twisting methods influence the physical properties of plied yarn. The yarns twisted on balloonless twisting machines have lower hairiness and tenacity values than those of the yarns twisted on other machines while the yarns twisted on two-for-one twisting machines attain higher hairiness and twisting variance values than those of the yarns twisted on other machines. In terms of tenacity, the highest improvement obtained after plying occurs in the yarns twisted on two-far-one twisting machines while the lowest improvement is observed in the yarns twisted on balloonless twisting machines. Contrarily, the yarns twisted on ring and balloon less twisting machines show the highest improvement in hairiness and twisting variance values.
