Title: Hisaharu Takeuchi: Innovator in Nonwoven Fabric Technology
Introduction
Hisaharu Takeuchi is a notable inventor based in Ibaraki, Japan. He has made significant contributions to the field of nonwoven fabric technology, holding a total of 3 patents. His innovative work focuses on creating materials that enhance the separation of oil from liquids, showcasing his expertise in material science.
Latest Patents
Takeuchi's latest patents include a method for producing lining cloth and a method for separating oil from oil-containing liquids. One of his key inventions is a water-repellent nonwoven fabric made from melt-blown fibers. This fabric features a single filament denier ranging from 0.005 to 2.0, with a fiber packing ratio of 5 to 70%. The water pressure resistance index of this fabric is between 400 to 2,000 mmH.sub.2 O. This nonwoven fabric is particularly useful for oil-water separating filters, as it allows permeability to oil while remaining non-permeable to water. Additionally, he has developed a composite fabric that combines this nonwoven material with an air-permeable knitted or woven fabric, resulting in a product that is both air permeable and water repellent.
