Title: Hiroshi Kakiuchi: Innovator in Synthetic Fibers
Introduction
Hiroshi Kakiuchi is a notable inventor based in Kanagawa, Japan. He has made significant contributions to the field of synthetic fibers, particularly in the development of materials that mimic natural textures. With a total of 2 patents, Kakiuchi's work has implications for various applications, including artificial hair for wigs.
Latest Patents
Kakiuchi's latest patents focus on synthetic fibers with uneven surfaces. The first patent describes a method for melt-spinning synthetic fibers that feature an uneven surface structure, consisting of wrinkles with ridges and recesses. This unique texture does not present a specular luster, making it suitable for use as artificial hair. The production process involves melt-spinning a starting synthetic resin, such as nylon, and passing the spun monofilament through a cooling bath at a temperature not lower than 30 degrees Celsius. This method allows for the development of wrinkles in the fiber's surface. Additionally, the inclusion of a pigment, such as carbon black, enhances the distribution of these wrinkles.
The second patent reiterates the same innovative approach to producing synthetic fibers with uneven surfaces. The emphasis on the method's stability and ease of production highlights Kakiuchi's commitment to advancing material technology.
