ABSTRACT OF THE DISCLOSURE Spun yarns are subjected to the vortex action of an impinging, circularly rotating fluid to lay down extending staple fibers against the yarn body while causing the yarn path to balloon and are then contacted with a melt size presented on a slower moving grooved melt size applicator. As a result of the ballooned yarn path, the yarn wipes melt size from the sides and bottom of the groove, giving the yarn a smooth, substantially continuous coating on its outside surface. Spun yarns so treated may be successfully woven as filling yarn on a water jet loom and knit as the warp yarn or as laid-in yarns on a knitting machine without excessive lint accumulation.
