Abstract:
An improved method and apparatus for forming nonwoven webs by spinning filaments into a quench chamber where they are contacted with a quenching fluid, then utilizing the quench fluid to draw the filaments through a two-dimensional nozzle spanning the full machine width, and collecting the filaments as a web on a porous surface. In contrast with the prior art, low motive fluid pressures can be used, and a non-eductive drawing means utilized to minimize air turbulence and the resulting filament entanglement in the drawing means while maintaining substantially constant cross machine filament distribution. The apparatus and process reduce problems relating to filament breakage and spreading and result in increased productivity and improved web formation. Other advantages include the ability to continuously spin highly pigmented polymer filaments and reduced hazards associated with high noise levels.
