Here is provided a confounding device for thermo-plasticity synthetic fiber multifilament to grant focusability, dissolve confounding ununiformity, provide lots of confounding by low air pressure, and generate natural dispersion and confounding of filament within the circular channel. Polyester 75 denier 36 filament is elongated and confounded by an air spray nozzle having an air pressure of 1.4Kg/Cm2, using two devices, each of which has three 3.2mm diameter circular channels(2) and two diameter 1.5mm rectilinear channels(1) respectively. Air of 1.0-2.0Kg/Cm2 pressure is sprayed branching lower compressed air from the rectilinear channel(1) into the circular one(2) which forms a double confounding point, as well as reducing air pressure loss.
