    摘要： Organic fibrous material is changed to heat-stabilized material by heating in an atmosphere, and then the heat-stabilized material is carbonized in a carbonizing furnace at a temperature of from about 800.degree.C to 1600.degree.C.When temperature at any given point in the furnace is plotted on a vertical axis and the particular location along the length of the carbonizing furnace is plotted on a horizontal axis, the slope of the resulting temperature profile above 800.degree.C either remains constant or decreases until the maximum temperature in the furnace is reached.

    摘要： Provided is a process for producing a carbon fabric composed of carbon fibers having improved tensile strength and modulus of elasticity from a precursor fabric made of an acrylonitrile polymer fiber. The acrylonitrile polymer fiber used has a fusing temperature of at least 310.degree. C., contains not more than 0.1 wt. % of a residual solvent, and is prepared by a process wherein an acrylonitrile polymer comprised of at least 94 wt. % of acrylonitrile and not more than 6 wt. % of another comonomer and having an intrinsic viscosity of 1.4-2.3 is spun into filaments and then the filaments are stretched at a total stretching ratio of at least 6. The fiber of the fabric woven therefrom is treated with a transition metal-containing compound. The precursor fabric exhibits a free areal shrinkage of not more than 50% and has a weight per unit area falling within the specified range. The precursor fabric is heated in an oxidizing gas atmosphere at 200.degree.-400.degree. C. under conditions such that the fabric is permitted to shrink by at least 80% of the free areal shrinkage, and then, carbonized at at least 700.degree. C. in a non-oxidizing atmosphere.

    摘要： A process for producing a carbon fabric wherein a fabric, which is made of an acrylonitrile polymer fiber having a fusing temperature (T.sub.f) of at least 310.degree. C. and exhibits a free areal shrinkage of not larger than 50%, is heated in an active gas atmosphere under conditions such that shrinkage of the fabric is permitted, thereby to be stablized, and then, the fabric is carbonized in an inactive gas atmosphere.
