Title: Daisuke Kawakami: Innovator in Flame-Resistant Materials
Introduction
Daisuke Kawakami is a notable inventor based in Ehime, Japan. He has made significant contributions to the field of flame-resistant materials, holding 2 patents that showcase his innovative approach to polymer and fiber technology.
Latest Patents
Kawakami's latest patents include a dispersion containing flame-resistant polymer, flame-resistant fiber, and carbon fiber. This dispersion improves the shaping stability of the flame-resistant polymer during ejection from a die orifice, as well as the physical stability of the shaped product during washing. The dispersion is characterized by a tensile strength of 1.0 MPa or more and 6.5 MPa or less, with the flame-resistant polymer being obtained through heat treatment of an acrylonitrile polymer in the presence of acids in a polar organic solvent.
Another significant patent focuses on the production of flame-resistant fibers and carbon fibers. This process enhances the fiber-forming ability of the flame-resistant polymer, resulting in high-performance fibers. The method involves wet or semi-dry spinning of a modified polymer solution, followed by controlled drawing and drying processes to prevent crystallization. The resulting carbon fiber is produced by carbonizing the flame-resistant fiber.
