摘要：A process for producing a nonwoven web of thermoplastic polymer fibers comprises extruding a thermoplastic polymer through a series of die openings while passing a stream of hot gas from both sides of the die openings to impinge and attenuate the molten extruded resin fibers, wherein the gas is passed through a plurality of flow distribution holes and through a flow deflector to intermix gas jets discharging from the holes.
