Abstract: A process for cooling, demonomerizing and dedusting gas from a thermoplastic polymer drier includes directing the gas, containing thermoplastic polymer dust, monomers and water, into a packed column with a packing and washing the gas with a solvent.

Abstract: An apparatus for extruding a wide variety of plural-component and mixed monocomponent fiber configurations in a spin pack utilizes one or more disposable distributor plates in which distribution flow paths are formed on one or both sides to distribute the polymer components to appropriate spinneret inlet hole locations. The distributor plates are inexpensive compared to drilled, milled, reamed, etc., plates and may be very thin, rendering the fabrication expense for the plates small, relative to the remainder of the spin pack, as to justify discarding or disposing of the plates rather than periodically cleaning them. The distribution paths may be small and densely packed, whereby the spinneret orifices can be more densely packed in the spinneret and staggered as between rows and columns so as to increase the fiber yield per given spinneret surface area.
