Title: Kenichi Katsuo: Innovator in Elastic Yarn Technology

Introduction

Kenichi Katsuo is a prominent inventor based in Tsuruga, Japan. He has made significant contributions to the field of elastic yarn technology, holding a total of 4 patents. His innovative work focuses on developing advanced materials that enhance the performance and durability of textile products.

Latest Patents

One of his latest patents is for a thermosetting polyurethane-urea elastic yarn and the process thereof. This invention features a thermosetting polyurethane-urea elastic yarn with a thermosetting ratio of 45-65%. It is produced by reacting a polyglycol with a number average molecular weight of 600-6,000 and hydroxy at both terminals with a molar excess of a diisocyanate compound. The resulting isocyanate-terminated polymeric intermediate is then reacted with a diamine compound to create a segmented polyurethane-urea elastomer, which is subsequently spun into yarn. This elastic yarn exhibits superior mechanical properties and high thermosetting ratios, making it particularly suitable for thin knit fabrics used in panty hose.

Another notable patent involves a process for the production of polyester polyurethane elastomeric fibers. This process enhances humid aging resistance by reacting a polyester diol with an excess molar amount of an organic diisocyanate to prepare a urethane prepolymer. The prepolymer is then extended with a bifunctional active hydrogen compound and a diaminosilyl compound, resulting in a polyurethane that is spun into fiber and crosslinked during or after the spinning process.
