Torque, Detorque, Zero-Twist, Low Torque Yarns. Udo Schweizer’s Texturing Pages. The high amount of real twist that was thermoset in a false twisting process creates torque as the yarn is untwisted below the friction unit. Because of the “memory effect”, inherent to any thermoplastic material, the yarn wants to return to the twisted state.
