METHOD FOR FORMING FILAMENTS FROM A RESIN ABSTRACT A solution of resinous organosilicon polymer dissolved in an inert solvent is moved downstream as a film through a heated, film-forming zone having an inert atmosphere and a temperature above the polymer's melting point. The solvent is vaporized from the film and withdrawn from the film-forming zone. Molten resinous organosilicon polymer in the solvent-depleted film is withdrawn from the zone. The molten polymer is then directly melt spun into filaments which are gathered into a fiber. Various processing parameters are controlled.
