Abstract: A process for producing a voluminous, balanced and elastic ply yarn from a mixture of non-keratinous natural fibres and discontinuous man-made fibres or only discontinuous man-made fibres. The process comprises: A. TWISTING AT LEAST TWO SINGLE THERMOSET THREADS HAVING A TWIST FACTOR Alpha 1 OF 95-110 INTO PLY YARN HAVING AN INITIAL TWIST FACTOR Alpha 2 OF 110-125; B. THERMOSETTING SAID INITIAL TWIST OF SAID TWISTED YARN; C. OVERTWISTING THE PLY YARN IN THE DIRECTION OPPOSED TO SAID INITIAL TWIST WITH A TWIST FACTOR Alpha 3 OF 275-290 WHILE HEAT TREATING IT IN SAID OVERTWISTED STATE; D. RETURNING THE PLY YARN TO SAID INITIAL TWIST, AND E. SIZING THE PLY YARN IN A RELAXED STATE BEFORE WINDING THE PLY YARN ONTO A SUPPORT.
