Abstract A pile fabric, which may be used, for example, in carpets and in terry toweling, comprises a backing and a pile of plied yarns and singles yarns, each of the plied yarns consisting of two or more single yarns which are individually twisted by vortex jet air devices to form an alternating pattern of "S" twists and "Z" twists along their lengths. The singles yarns are joined at their nodes to form a plied yarn in which the spacing between the nodes may be selected to give an increased yarn bulk and with the singles yarns between the nodes false twisted in the same direction, the singles having either an "S" or a "Z" twist. The singles yarn between the fastened nodes are permitted to self-twist together in the opposite direction as the twist direction of the singles yarns, forming a stable self-twisted plied yarn.
A pile fabric comprising a backing and a plurality of tufts protruding from said backing, a selected proportion of said tufts consisting of self-twist plied yarn, said self-twist plied yarn consisting of a plurality of false twisted singles yarns, each singles yarn having a repeating pattern along its length of S twist and Z twist and nodes therebetween, said singled yarns being fastened together at said nodes and having the same direction of twist between said nodes, said self-twisted plied yarn being self-twisted in opposite directions to said singles yarns, and the remainder of said tufts consisting of substantially untwisted singles yarn in unplied yarn.
