Sony today announced that it has begun licensing Triporous, a plant-based porous carbon material, to the fiber and apparel industries. Triporous is a porous carbon material with a unique microstructure that is created from rice husks. In addition to the 2nm micropores found in activated carbon, it also contains large quantities of 2 to 50nm mesopores and 1μm macropores. Sony first began licensing Triporous in January 2019; it has collaborated with various companies and research institutions to promote the commercialization of Triporous products. Sony partnered with several companies to begin researching fibers to utilize Triporous


Products developed by using Triporous in the fiber and apparel industries will feature the trademark Triporous FIBER. Triporous FIBER is capable of quickly absorbing odor molecules like ammonia, acetic acid, and isovaleric acid that lead to body odor from sweating and other activities. The deodorizing agent also last longer and also desorbs the adsorbed particles in the washer, leading to the recovery of deodorizing functions. Additionally, it has also been found to have antibacterial and bacterial inhibiting effects for bacteria such as Moraxella osloensis, which are a source of unpleasant odors in partially-dried clothes.

Taking advantage of the outstanding adsorption characteristics of Triporous, Sony is working to develop products and solutions through licensing for a variety of fields that require water purification, air purification, or deodorization.
