21. However, for polyester fibres, the rotor spun yarn showed highest friction, followed by friction and ring spun yarns . 22. Friction spun yarns DREF yarns have bulky appearance ( 100-140 % bulkier than the ring spun yarns ). 23. However, for polyester fibres, the rotor spun yarn showed highest friction, followed by friction and ring spun yarns. 24. Friction spun yarns DREF yarns have bulky appearance ( 100-140 % bulkier than the ring spun yarns ). 25. The lack of elasticity in short draw spun yarns make them perfect for weaving, especially for the warp. 26. In wet weather the softly spun yarns -within the tight weave-dynamically expand to form an effective barrier against the elements. 27. The yarns possess only 60 % of the tenacity of ring-spun yarns and about 90 % of rotor spun-yarns. 28. If the flannel is not napped, it gains its softness through the loosely spun yarn in its woven form. 29. Holofiber is made with spun yarn that contains a ceramic substance that makes the fabric vibrate when it's worn. 30. DREF yarns are most irregular in terms of twist and linear density while ring spun yarns are most even.
