Latest Patents

Kenji Nagamatu holds a patent for a synthetic polyvinyl alcohol fiber and the process for its production. This invention provides a high-performance PVA fiber characterized by a structure comprising an aggregate of substantially innumerable fibrils. The fiber exhibits high strength, elastic modulus, and resistance to fatigue, hot water, and chemicals. Notably, it can be pulpified while maintaining its excellent features, such as high strength. The PVA fiber's fibril-aggregate structure prevents it from being readily whitened, even when drawn to a high ratio, allowing for enhanced performance. The fiber is produced by adding a relatively large amount of surface-active agent to a PVA solution and then wet or dry-jet-wet spinning the prepared dope solution into an aqueous alkaline coagulating bath.

Career Highlights

Throughout his career, Kenji Nagamatu has worked with prominent companies, including Kuraray Co., Ltd. and Akira Kubotsu. His experience in these organizations has contributed significantly to his expertise in fiber technology and innovation.
