Introduction

Eiichi Kubo, an accomplished inventor based in Uji, Japan, has made significant contributions to the field of nonwoven fabric technology. With a remarkable portfolio of five patents, his innovations focus on enhancing the performance and properties of nonwoven fabrics through advanced methods and materials.

Latest Patents

Among his latest innovations are two notable patents. The first involves a nonwoven fabric made from fine denier filaments that possess superior bulkiness, heat insulation properties, and tensile strength. This invention describes a production method that utilizes a bicomponent melt spinning technique. The method involves preparing two thermoplastic polymer components: Component 'A', and Component 'B', which is insoluble in Component 'A' and has a higher melting point. By heat-bonding the accumulated bicomponent conjugate filaments, a fleece is formed, which undergoes a wrinkling action to enhance its texture.

The second patent focuses on a heat-bondable fiber that features a core-sheath type composite fiber structure. The core component is made from a fiber-forming polymer with a melting point exceeding that of the sheath component by over 30°C. This design ensures high adhesion to other dissimilar fibers while maintaining a soft hand for the resulting nonwoven fabric.
