Title: Masami Fujimoto: Innovator in Composite Elastic Filaments
Introduction
Masami Fujimoto is a notable inventor based in Kudamatsu, Japan. She has made significant contributions to the field of materials science, particularly in the development of composite elastic filaments. With a total of 3 patents to her name, her work has garnered attention for its innovative approach and practical applications.
Latest Patents
Fujimoto's latest patents include a composite elastic filament with a rough surface. This invention consists of a sheath component made from a fiber-forming thermoplastic polymer, such as polyamide, polyester, or polyolefin, and a core component made from a fiber-forming elastomer, such as polyurethane or polyester elastomer. The core/sheath conjugate ratio ranges from 1/1 to 100/1 by cross-sectional area. The core portion features a smooth peripheral surface that extends uniformly along the filament axis, while the sheath portion is characterized by numerous ridges that rise along the circumference and are closely spaced along the filament's length. This filament can be produced through melt conjugate spinning, followed by drawing and relaxation. It exhibits excellent elastic properties, a low surface friction coefficient, and a matting effect due to diffuse reflection of light from the rough surface, making it particularly suitable for use in textile structures, such as lady's stockings.
