Latest Patents

One of Muraguchi's latest patents involves methods of bleaching jeans. This process utilizes rotating glass-expandable ceramics with specific properties, including a bulk specific gravity of 0.7 to 1.2 and a 24-hour water absorption rate of no greater than 5%. The method involves using water and jeans in a rotary tank to achieve the desired bleaching effect. Additionally, he has developed a technique that employs 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 to enhance the bleaching process.

Another significant patent by Muraguchi focuses on the production of an alumina porous body. This invention comprises coarse alumina particles as a filler combined with SiO₂. The reaction between alumina and SiO₂ during firing forms an Al₂O₃-SiO₂ compound (mullite) that binds the coarse alumina particles, creating pores between them. The process involves mixing coarse alumina particles with SiO₂, molding the mixture, and firing it at a temperature not exceeding 1700°C to achieve sintering.
