Abstract
The present invention provides a process and apparatus for collecting relatively straight blow spun fibers in a two dimensional configuration. The process utilizes a venturi to preclude the kinking and bending of the fibers until the fibers have substantially thermoset. A diffusion chamber allows the fibers to be collected without entangling.
