Abstract : A method is given for obtaining flame-resistant polyacrylonitrile fiber or fabric by thermal treatment (carbonizing) at 200C which is distinguished by the fact that in order to increase the heat resistance while retaining mechanical properties, the polyacrylonitrile fiber or fabric is subjected to stepwise treatment beginning at 200C and then carrying through to 400-475C.
