Title: Toshinori Kawamura: Innovator in Fiber Heat Treatment Technology.
Introduction
Toshinori Kawamura is a prominent inventor based in Osaka, Japan. He has made significant contributions to the field of fiber heat treatment technology. With a total of 2 patents, his work focuses on improving the efficiency of heat treatment processes for fiber bundles.
Latest Patents
Kawamura's latest patents include a yarn guide roller and a heat treatment furnace for fiber. The heat treatment furnace is designed for heat-treating a fiber bundle formed of many continuous filaments in hot gas while the yarn is running. This innovative furnace features multiple heat treatment chambers, each with independently adjustable temperatures. This design allows for a compact furnace that efficiently heat-treats fibers, particularly for producing oxidized fibers necessary for carbon fiber production. The process involves a polyacrylonitrile-based fiber bundle passing through a zigzag yarn path, which is established by a combination of yarn guide rollers. These rollers have specific grooves that adjust the yarn's cross-sectional shape, reducing heat accumulation during treatment.
