Title: Eizou Sakurai: Innovator in Composite Fibers and Magnetic Storage
Introduction
Eizou Sakurai is a notable inventor based in Aichi, Japan, recognized for his contributions to the field of composite fibers and magnetic storage technology. With a total of two patents to his name, Sakurai has made significant advancements that enhance the functionality and performance of various materials.
Latest Patents
Sakurai's latest patents include an acrylic-based composite fiber and a method for its production. The objective of this invention is to provide an acrylonitrile-based composite fiber that offers a unique feel, distinct from ordinary cellulose acetate fiber, cellulose fiber, and acrylic fiber. This innovative fiber boasts excellent spinability, fiber properties, and processability in yarn spinning. Notably, it also features remarkable functions, particularly a deodorizing capability and moisture-absorbing and retaining properties. The composite fiber consists of 10 to 40% by weight of cellulose acetate and/or cellulose, combined with 60 to 90% by weight of an acrylonitrile-based polymer. The structure of the fiber allows for the cellulose acetate and/or cellulose to form an island component in a cross-section perpendicular to the fiber axis, while the acrylonitrile-based polymer forms a sea component.
Additionally, Sakurai has developed a floppy disk that utilizes a polyester polyurethane binder to fix a magnetic substance in the recording layer. The jacket liner of this floppy disk contains an acrylic fiber and a fiber treating agent with a specific surface tension. This design enhances workability, reduces dust generation during preparation, and improves the permanence of recording performance.
