Latest Patents

Kawanishi's latest patents include methods for bleaching jeans. This innovative process involves rotating glass-expandable ceramics with specific properties in a rotary tank containing water and jeans. The ceramics have a bulk specific gravity of 0.7 to 1.2 and a 24-hour water absorption of no greater than 5%. Additionally, he has developed a method using an air-permeable ceramic porous material, which has a bulk specific gravity of 0.7 to 1.9 and a 24-hour water absorption of 10 to 40%. This material can also be immersed in a bleaching agent solution during the process.

Another significant patent is for a thermally insulating foam glass tile. This tile consists of a vitrifiable mineral body with a closed cell structure and features a rigid reinforcing vitrified surface skin. An intermediate vitrified layer, which has a lesser volume of closed cells, is integrally melt-bonded between the tile-like body and the surface skin.
