Yarns produced by DREF-III frictional spinning have unique core-sheath structures which render them ideal for such technical applications as protective clothing, transportation material and filters, among others. To understand the torsional behavior of DREF-III frictional spun yarns, measurements of the level of `snarling twist' and `snarling distance' were performed on 100% carried cotton slivers tested in air and water. Fabric spirality of the specimens were obtained using a modified procedure based on the IWS Test Method 276. The process produced a dramatic reduction in the snarling tendency of the DREF-III yarns. The spirality of the knitted fabric was greatly reduced and the tactile qualities were improved.
