摘要： A hollow filament comprising a filamentary polymer composed predominantly of a flame-resistant and anti-fusing cured novolak resin, characterized in that the hollow structure continuously extends in the axial direction of the filament, the degree of hollowness thereof being in the range of 10 - 80%, and a process for producing the same which comprises treating a filament consisting of a fiber-forming polymer of predominantly an uncured novolak resin composition, with a curing reagent in the presence of a curing catalyst to effect the cure of said filament extending from the peripheral portion to the axial portion thereof to a depth of 20-90% of the cross-sectional area of the filament, and thereafter removing the uncured core portion of said filament by extraction with a solvent.
