Title: Syunichi Kiriyama: Innovator in Nonwoven Fabric Technology
Introduction
Syunichi Kiriyama is a notable inventor based in Gose, Japan. He has made significant contributions to the field of nonwoven fabric technology, holding a total of 3 patents. His innovative work focuses on creating high-quality nonwoven fabrics that are both strong and soft.
Latest Patents
One of his 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 provide superior strength and softness. The fabric is created by heat-bonding filaments of linear low-density polyethylene, ensuring that the number of defects is not more than 0.01/kg. The weight of the fabric ranges from 10-100 g/m², with a percentage bond area of 7-20% and a total hand value of 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 utilize bicomponent filaments with a sheath component made of linear low-density polyethylene and a core component made of polyethylene terephthalate.
