Abstract
PURPOSE:To prevent the occurrence of flames on a separation layer, even if a separation membrane is wound on a reel and the adjacent sections of the membrane are rubbed against each other, by controlling to maintain the Bekk smooth of the back of a base material layer above the specified value. CONSTITUTION:A cloth made of polyester fiber is used as the base material layer 11, and calendered to hold the Bekk smoothness of its back at >=1.0sec. The surface of the base material layer is coated with a polysulfone soln., the material is immediately dipped in water to solidify the soln., and a porous layer 12 is formed. A substrate layer 13 of a cross-linking silicone membrane, etc., is formed on the porous layer 12, a soln. of cyclohexane in poly(4- methylpentene-1) diluted with freon is then applied and dried, and a gas separation membrane is formed.
