Patent number: 6860922Abstract: The present invention provides a gas-permeable hollow fiber membrane having an inner diameter of 50 to 500 ?m and a membrane thickness of 10 to 150 ?m, which is preferably a composite hollow fiber membrane having a three-layer structure consisting of a nonporous layer having porous layers disposed on both sides thereof. Dissolved gases present in an ink can be removed by passing the ink through the bores of hollow fibers comprising such a hollow fiber membrane, and evacuating the outer surface side of the hollow fibers. This method makes it possible not only to degas inks with a slight pressure loss, but also to degas inks stably even if pressure changes occur during degassing.Type: GrantFiled: June 24, 2002Date of Patent: March 1, 2005Assignee: Mitsubishi Rayon Co., Ltd.Inventors: Kenji Watari, Satoshi Takeda, Masumi Kobayashi, Makoto Uchida, Masamoto Uenishi, Noriaki Fukushima, Seiji Hayashi
