Title: Yasunobu Mishima: Innovator in Nonwoven Fabric Technology
Introduction
Yasunobu Mishima is a notable inventor based in Uji, Japan. He has made significant contributions to the field of nonwoven fabric technology. With a total of 3 patents to his name, Mishima's work focuses on creating innovative materials that enhance the quality and functionality of nonwoven fabrics.
Latest Patents
One of Mishima's latest patents is for a polyolefin-type nonwoven fabric and the method of producing it. This nonwoven fabric is formed from highly spinnable heat-bonded continuous filaments, which are both strong and soft, providing superior hand feel. The fabric is created by heat-bonding filaments of linear low-density polyethylene, ensuring that the number of defects does not exceed 0.01/kg. The weight of the fabric ranges from 10-100 g/m², with a bond area percentage of 7-20% and a total hand value between 4-300 g. The production process involves melt-extruding linear low-density polyethylene to form filaments, which are then drawn by air guns at high speed and deposited on a moving collection belt to create a web. This web is subsequently heat-treated at a temperature 15-30°C lower than the melting point of the filaments. The nonwoven fabric can be made from filaments with either a hollow or flat cross-section, and it is also possible to use bicomponent filaments that consist of a sheath made of linear low-density polyethylene and a core made of polyethylene terephthalate.
