Abstract

PURPOSE:To raise mechanical strength, heat resistance, and pH resistance, by forming a permeable membrane on a base having a nonwoven fabric layer having specified values of thickness, basis weight, and gas permeability, and consisting of polypropyrene single fiber. CONSTITUTION:Polysulfone, polyimide, or the like polymer is dissolved in an organic solvent to prepare a dope. This dope is coated on a nonwoven base made of polypropyrene single fiber of 10-33mum diameter, having 0.05-2mm. thickness, 20- 600g/m<2> basis weight, and 0.2-55cc/cm<2>/sec gas permeability, and then solidified to form a reinforced permeable membrane. As a solvent for preparing the dope, dimethyl formamide, dimethyl sulfoxide, dioxane, or the like ordinary organic solvent is usable, and an additive such as sodium chloride can be added to the dope.
