Title: Tsuneo Genba: Innovator in Nitrogen Separation and Shrinkable Fibers

Introduction

Tsuneo Genba is a notable inventor based in Okayama, Japan. He has made significant contributions to the fields of gas separation and textile technology. With a total of 6 patents, his work has paved the way for advancements in high-purity nitrogen production and innovative fiber materials.

Latest Patents

One of Genba's latest patents is a process for separating nitrogen gas. This process utilizes a nitrogen gas separation apparatus of a pressure-swing adsorption type. It includes a gas transfer step between an adsorber that has completed an adsorption step and another adsorber that has completed a regeneration step. The gas transfer step also involves discharging part of the gas being transferred out of the system. This innovative process provides high-purity product nitrogen with a purity of at least 99.99%, which has been considered difficult to obtain with conventional pressure-swing adsorption apparatuses.

Another significant patent involves rapidly shrinking fibers and water-absorbing shrinkable yarn. These fibers are hardly soluble in water and can shrink in water at 20 degrees Celsius by not less than 30% in under 10 seconds. They are produced by spinning, drawing, and heat-treating a carboxy-modified polyvinyl alcohol under specific conditions. Yarns made from this type of fiber, along with nonwoven fabrics incorporating these rapidly shrinking fibers, are particularly suited for tightly fitting edge portions of disposable diapers to the thigh.

Career Highlights

Throughout his career, Tsuneo Genba has worked with prominent companies such as Kuraray Co., Ltd. and Kuraray Chemical Co., Ltd. His innovative approaches have significantly impacted the industries he has been involved in.
