    Abstract: According to the method of this invention, heat-resistant fibers and flame-retardant fibers are produced from organic fibers by heating the said organic fibers to a temperature between 180*C and 350*C in an atmosphere containing oxygen gas in a concentration of at least 25%, in a high oxygen content atmosphere containing acid vapor, or in a high oxygen content atmosphere and then in an acid-vapor containing, high-oxygen content atmosphere. Furthermore, the heat-resistant fibers having higher heat-resistant property (carbon and graphite fibers) are produced by heating the said flame-retardant fibers to a temperature between 350*C and 3,000*C in a non-oxidizing atmosphere or in vacuum. In accordance with the method of this invention, the duration of the entire operation of heat treatment for producing the said heat resistant fibers can be shortened to a great extent while the said-heat treatment procedure enables the heat-resistant fibers produced to have quality favorably comparable with that of the heat-resistant fibers obtainable by the conventional method.

    Abstract translation: 根据本发明的方法，耐热纤维和阻燃纤维由有机纤维制成，在含氧气氛中加热所述有机纤维至180℃至350℃的温度，其浓度为 至少25％，在含有酸性蒸汽的高氧含量气氛中，或在高含氧气氛中，然后在含有高氧气氛的酸性气体中。 此外，通过在非氧化性气氛或真空中将所述阻燃纤维加热至350℃至3000℃的温度，制得具有较高耐热性的耐热纤维（碳和石墨纤维）。 根据本发明的方法，可以在很大程度上缩短用于生产所述耐热纤维的热处理的整个操作的持续时间，而所述热处理步骤使得所生产的耐热纤维具有良好的质量 与通过常规方法可获得的耐热纤维相当。

    Abstract: WOOD OR OTHER VEGETABLE MATERIAL HAVING A NON-UNIFORM SHAPE SUCH AS SHAPELESS PARTICLE POWDER, FLAKY POWDER, CHIP AND THE OTHERS IS CARBONIZED IN AN ACIDIC ATMOSPHERE CONTAINING VAPOR OR GAS OF HYDROCHLORIC OR HYDROBROMIC ACID OR ITS ANHYDRIDE FOR 10 MINUTES TO 10 HOURS AT A TEMPERATURE OF 80-1200* C. TO OBTAIN ACTIVATED CARBON OF SUPERIOR ADSORPTION ACTIVITY IN VERY HIGH YIELDS. IF DESIRED, THE ACTIVATED CARBON SO OBTAINED IS HEATED FURTHER IN AN ATMOSPHERE CONTAINING AN OXIDIZING GAS SUCH AS STEAM, CARBON DIOXIDE GAS OR AIR, OR IN AN INERT ATMOSPHERE TO IMPROVE THE ADSORPTION ACTIVITY OF SAID CARBON.

    Abstract: PURPOSE:To manufacture the titled material of a high reinforcing efficiency, by impregnating under pressure Al or Mg metal in liquid state to carbon fiber covered with film of carbon or mixture of carbon and metal carbide and boron nitride, etc. CONSTITUTION:Carbon fiber is covered with film composed of >=95% carbon, at least one among mixture of carbon and metal carbide and BN as main components. Carbides of Si, Ti, Zr, Nb, Ta, W, etc., are suitable to the metal carbide. The film of 0.01-2mum thickness and carbon fiber calcined at 1,000-2,000 deg.C are favorable. To outside of the film, further film mainly composed of one kind or more of metal carbide, TiN, Si3N4 or that composed mainly of compd. contg. one or two kinds among Si, Ti, Al, B, Zr, and C, O can be covered. The covered carbon fibers and Al or Mg metal in liquid state are contacted, pressed and composited by >=10kg/cm , favorably about 100-1,100kg/cm pressure, to obtain fiber reinforced composite material.

    Abstract: PURPOSE:To obtain the titled fiber for the deodorization of gas and having high absorptivity and flexibility, in high yield in a short time, by heating and carbonizing cellulosic fibers having specific average length in an atmosphere containing hydrogen chloride and heating in an atmosphere such s steam at a high temperature to effect the activation of the fiber. CONSTITUTION:Cellulosic fibers having an average single fiber length of >=10mm are carbonized by heating in an atmosphere containing >=3vol% hydrogen chloride gas at 150-500 deg.C and activated by heating in an atmosphere containing >=5vol% steam or carbon dioxide gas at 600-1,000 deg.C to obtain the objective fiber having high adsorptivity and flexibility. The carbonization treatment of the fiber in an atmosphere containing hydrogen chloride gas is carried out preferably by heating from 150-250 deg.C to 270-500 deg.C.
