THE METHOD OF PRODUCING A SHOT-FREE, RETICULATED, FIBROUS BODY WHICH COMPRISES PROVIDING A FIBER-FORMING LIQUID CONTAINING A POTENTIALLY ADHESIVE, FIBER-FORMING THERMOPLAST, CREATING A HIGH VELOCITY, UNDIRECTIONAL, FREEFLOWING, UNCONFINED AND UNRESTRICTED JET STREAM OF GAS BY DISCHARGING A HIGH VELOCITY STREAM OF GAS INTO THE ATMOSPHERE WITHIN A CHAMBER, THE DIAMETER OF THE JET STREAM OF GAS AT THE POINT OF DISCHARGE BEING INSIGNIFICANT WITH RESPECT TO THE DIMENSIONS OF THE CHAMBER INTO WHICH THE GAS IS DISCHARGED, EXTRUDING THE FIBER-FORMING LIQUID INTO AND WITHIN THE JET STREAM OF GAS AT A POINT BEYOND THE POINT IN THE JET STREAM AT WHICH THE LIQUID IS DISRUPTED, THE DIRECTION OF EXTRUSION BEING COINCIDENT WITH THE DIRECTION OF THE GAS FLOW, ATTENUATING THE EXTRUDED FIBER-FORMING LIQUID, THEN BREAKING THE ATTENUATED FIBER-FORMING LIQUID INTO DISCONTINUOUS LENGTHS AND AT LEAST PARTIALLY SETTING THE FIBER-FORMING LIQUID TO FORM DISCONTINUOUS FIBERS BY MAINTAINING THE VELOCITY OF THE JET STREAM OF GAS AT THE POINT OF DISCHARGE AT A VALUE GREATER THAN THE VELOCITY OF EXTRUSION OF THE FIBER-FORMING LIQUID, AND COLLECTING THE DISCONTINUOUS FIBERS IN RANDOM DISTRIBUTION TO FORM A SHOT-FREE, RETICULATED, SHEET-LIKE FIBROUS BODY.
