An apparatus for interlacing a multifilament yarn includes a housing with a conduit defined therethrough. A jet nozzle is configured with the housing. The jet nozzle includes a main channel symmetric to the yarn conduit axis and at least two side channels. The main channel directs a greater volume of pressurized air into a central region of the yarn conduit as compared to the side channels that direct a lesser volume of pressurized air to peripheral zones where substantially no interlacing of the yarn takes place.
