Title: Method of producing fiber strand

Abstract: A wet process for producing continuous strands from discontinuous inorganic fibers by extruding and aligning a dispersion of said fibers in a liquid medium, which medium contains a gelable agent, into a coagulating bath to gel and convert the agent to a binder for the fibers until they are mechanically interlocked, and subsequently removing the binder. A fibrous strand produced in accordance with the process, with and without the binder included.
