Title: Sachie Kitabata: Innovator in Water-Absorbing Technologies
Introduction
Sachie Kitabata is a prominent inventor based in Himeji, Japan. She has made significant contributions to the field of water-absorbing agents, particularly in the development of materials used in disposable diapers and heat-generating elements. With a total of 3 patents to her name, her work has had a substantial impact on product efficiency and performance.
Latest Patents
One of her latest patents is focused on a Poly (meth) acrylic acid (salt)-based particulate water-absorbing agent and its production method. This invention aims to provide a disposable diaper that reduces re-wet amounts while ensuring excellent liquid absorption speed, regardless of the concentration and configuration of the water-absorbing agent in the absorbent material. The water-absorbing agent developed by Kitabata exhibits remarkable Gel Capillary Absorption (GCA) and Free Gel Bed Permeability (FGBP). This is achieved by crushing a crosslinked hydrogel polymer to a specific weight average particle diameter, adjusting fluid retention capacity and surface tension, and enhancing liquid permeability during or after surface crosslinking.
Another notable patent involves a water-absorbing resin powder for heat-generating element compositions. The objective of this invention is to minimize the generation of aggregates and adhesion of the water-absorbing resin during the production of heat-generating elements. The innovative resin powder includes polyacrylic acid (salt)-based materials with specific properties, such as a bulk specific gravity of 0.630 g/cm³ or less and a fluid retention capacity of 32.0 g/g or less for a 0.9% sodium chloride solution.
Career Highlights
Kitabata is currently employed at Nippon Shokubai Co., Ltd., where she continues to advance her research and development efforts.
