Patent number: 4080417Abstract: A process for producing carbon fibers by heat-treating an acrylonitrile fiber, containing or impreganted with an aminosiloxane, at a temperature of at least 150.degree. C for 0.1 second to 30 minutes so that the fiber contains 20 to 80 weight % undissolved matter upon immersing it in a 60% aqueous solution of sodium thiocyanate at 80.degree. C for 20 minutes, and then carbonizing the fiber, whereby the productivity throughout the whole process, including the step of producing the precursor fiber and the step of producing the carbon fiber, is increased and a carbon fiber having high tensile strength and high modulus of elasticity is obtained in an industrially advantageous manner.Type: GrantFiled: September 8, 1976Date of Patent: March 21, 1978Assignee: Japan Exlan Company LimitedInventors: Soichiro Kishimoto, Saburo Okazaki
