ABSTRACT:
In a process for the production of fibers from phenoplast resins of the resole type, the resin is treated with a cross-linking agent and is immediately thereafter introduced into a centrifuge bushing. The fibers extruded from the bushing are projected into the surrounding atmosphere which is heated so as to accelerate the drying of the fibers before they are collected. The heating is sufficient so that the fibers become solid and non-sticky prior to collecting.
