Latest Patents

Maruo's latest patents include a gastight woven fabric sheet for airbags and a process for producing the same. He has also developed a method of manufacturing a cut pile carpet and a pile yarn for a carpet. His innovative approach involves feeding a bulky yarn of polyamide multifilament to a false twisting and heat setting device. In this process, the filaments in the yarn are thermally and partially adhered to each other while the yarn is false twisted. The resulting bulky cohesive continuous multifilament yarn has alternate twists along its length and a latent torque. After heat treatment under constrained conditions, preferably using saturated or superheated steam, the yarn is tufted onto a carpet substrate as a pile yarn, and the piles are subsequently cut.
