<p>A method and apparatus is provided for producing a synthetic multifilament yarn having the appearance, bulk and hand characteristics normally associated with spun yarns of staple fibers. The yarn is air jet textured to form loops, coils, bows and the like in the filaments, and at least some of the projecting loops, coils, and bows are enlarged or parted by advancing and looping the yarn around one or more rotating rollers, such that the portion of the yarn running onto the roller overlaps and contacts the portion of the yarn leaving the roller and thereby clampingly engages the projecting loops, coils, bows and the like of the leaving yarn portion. The efficiency of the process may be controlled by varying the number of rollers, as well as the yarn tension during the parting operation.</p> |
