The process along with the doubled production on ring frame and omission of the intermediate machine, parallel winding machine and doubler twister gave a yam with better uniformity and strength and a fabric with high strip strength, tearing strength and less stiffness. However, yarn abrasion resistance and pilling tendency were poor. Siro yarn had a greater diameter than the conventional two-fold yarn.</span>
