ABSTRACT:
A process is disclosed for producing a continuous multifilament yarn of melt-spinnable, polymeric material which is essentially free from stretch and which comprises draw-texturing a first continuous filament yarn end, combining the first end with a second flat continuous filament yarn end, and feeding the combined textured and flat ends through a jet interlacer in an overfeed condition with the textured end being fed at a greater rate of overfeed than that of the flat end. An alternate process is disclosed wherein draw-texturing of the first textured yarn end and drawing of the second flat yarn end are performed simultaneously prior to jet interlacing of the overfed combined ends. Also disclosed is the spun-like continuous multifilament yarn produced by the novel process as well as resulting fabric made from the yarn.
