a high-pressure air-inlet hole whose ratio of length to diameter (L/D) is 6-30, and shape is spiral form that satisfies the following equation, D P 3D (where p: pitch of the screw, l: distance between the screw's top and the screw's groove, D: diameter of the high-pressure air-inlet hole; a multifilaments' passing hole; and a compressed air-outlet slit. Interlaced fibers' number per unit length of the multifilament treated by the apparatus shows move than 30 % increase than that by the conventional interlacing apparatus under the same air-pressure, and the uniformity of the interlacing by this apparatus is excellent.
