Title: Shigezou Kojima: Innovator in Non-Woven Fabric Technology
Introduction
Shigezou Kojima is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of non-woven fabric technology. With a total of 2 patents, his work has advanced the understanding and application of non-woven materials in various industries.
Latest Patents
Kojima's latest patents include innovative methods for creating non-woven fabrics. One of his notable inventions is a method and apparatus for making cross-laminated stretched non-woven fabric. This non-woven fabric boasts a strength comparable to that of woven fabric. The fabric features a laminated structure composed of a warp web of random-laid non-woven fabric that is stretched lengthwise, providing greater strength in that direction. Additionally, a weft web of random-laid non-woven fabric is stretched transversely, enhancing strength in the transverse direction. The filaments in both the warp and weft webs are designed to be free from molecular orientation, allowing them to stretch at least two times their original length before the web is stretched. This stretching process leads to molecular orientation within the filaments, resulting in enhanced material properties.
Career Highlights
Throughout his career, Kojima has worked with notable companies, including Nippon Petrochemicals Company, Limited and Polymer Processing Research Institute, Ltd. His experience in these organizations has contributed to his expertise in polymer processing and material innovation.
