Title: Kazuya Hayashi: Innovator in Synthetic Fiber Technology
Introduction
Kazuya Hayashi is a notable inventor based in Otsu, Japan. He has made significant contributions to the field of synthetic fiber technology, holding 2 patents that showcase his innovative approach to materials science.
Latest Patents
Hayashi's latest patents include a dyed synthetic fiber comprising silver-substituted zeolite and copper. This invention describes a dyed synthetic fiber that possesses antibacterial and antifungal properties. The fiber contains 0.01 to 20 weight % of a silver-substituted zeolite and 0.001 to 1.0 weight % of a substantially water-insoluble copper compound. The copper compound is incorporated independently of zeolite particles in the fiber. The process involves incorporating the silver-substituted zeolite in a monomer or polymerization mixture before polymerization is complete, followed by the addition of the copper compound before spinning the polymer into fiber and dyeing it. This innovative fiber retains a high level of antibacterial and antifungal properties.
Another significant patent by Hayashi is a process for treating a fibrous structure. This process involves a fibrous structure that comprises at least two components, one of which is a polyester containing an SO₃ M group, where M represents hydrogen or an alkali metal. The treatment process is characterized by using an agent that deteriorates the polyester prior to alkali treatment for the removal of the polyester component.
