    摘要： A process is provided for producing non-woven fabrics in which adhered points supporting the non-woven fabrics structure are the same carbon materials with the component fibers and which is superior in strength, dimensional stability, heat-resisting property, chemical resistance, electric conductivity, etc.
    This process comprises mixing spun pitch fibers or insufficiently infusiblized pitch fibers with infusiblized pitch fibers or carbonized pitch fibers, shaping the mix­ture into a sheet or the like and thereafter carbonizing the shaped mixture in the atmosphere of an inert gas to mutually fix the component fibers by utilizing the adher­ing property of the spun pitch fibers or the insuffi­ciently infusiblized pitch fibers during the carboniza­tion.
