Title: Hirokazu Matsui: Innovator in Biodegradable Filaments
Introduction
Hirokazu Matsui is a prominent inventor based in Ibaraki-ken, Japan. He has made significant contributions to the field of materials science, particularly in the development of biodegradable filaments. With a total of 2 patents, Matsui's work focuses on creating sustainable materials that have practical applications.
Latest Patents
Matsui's latest patents include a process for making polyglycolic acid resin filament. This innovative filament is biodegradable and possesses high tensile strength and knot strength. The process involves melt-spinning a polyglycolic acid resin with a residual monomer content of below 0.5 wt. %. The filament is then quenched in a liquid bath at a maximum temperature of 10°C and stretched in a liquid bath at 60-83°C. The result is a polyglycolic acid resin filament with a tensile strength of at least 750 MPa and a knot strength of at least 600 MPa.
Another notable patent is for a modified polyvinylidenefluoride resin monofilament. This invention is designed for fishing lines intended for capturing large fish. The filament enhances tensile strength by increasing the diameter compared to standard fishing lines. This design reduces the rapid and enormous impact generated when large fish take the bait, while also ensuring a homogenous fiber structure that minimizes inner cavities.
