Latest Patents

Okazaki's latest patents include a process for producing carbon fibers with excellent properties. This innovative process involves heat-treating an acrylonitrile fiber, which is either containing or impregnated with an aminosiloxane, at a temperature of at least 150 degrees Celsius for a duration of 0.1 seconds to 30 minutes. The resulting fiber contains 20 to 80 weight percent undissolved matter when immersed in a 60% aqueous solution of sodium thiocyanate at 80 degrees Celsius for 20 minutes. This method increases productivity throughout the entire process, leading to the production of carbon fibers with high tensile strength and high modulus of elasticity in an industrially advantageous manner. Another patent details a similar process that involves heat-treating an acrylonitrile fiber impregnated with specific primary amines and/or quaternary ammonium salts, resulting in a partly insoluble acrylic fiber that is thermally stabilized before carbonization.
