Abstract: An improved apparatus and method for commingling multifilament yarn has been found. The apparatus comprises an elongated body having a straight yarn passageway with at least three orifices substantially equally spaced about the periphery of the body at substantially the same level. The orifice center lines are offset so that at least two do not intersect with the center of the effective diameter of the yarn passageway, yet all pass within an imaginary circle having a diameter about one-third the effective diameter, and the same center as the effective diameter, at the orifice level. Also, at least two of the center lines extended from the orifices should pass outside the imaginary circle at the orifice level section having the same center but only 0.02 of the effective diameter of the yarn passageway. The plane at the orifice level must be located within a length one-half the length of the yarn passageway and centered on the midpoint of the yarn passageway. These orifices communicate with a source of high pressure fluid. The high pressure fluid flows through the orifices into the yarn passageway causing a vortex of swirling fluid so that any yarn passing linearly through the passageway would have filaments commingled with one another. This improved process of entangling multifilament yarn can operate at from about 3,000 to about 8,000 feet per minute by passing continuous multifilament yarn through the above-described vortex.
