Embodiments of the present disclosure generally relate to gas separation membranes which have one or more selective layers, methods for preparing such membranes, and methods for separating gases with such membranes. The gas separation membranes are capable of permeating one gas component selectively to a low-pressure or low-concentration permeate side at a greater transport rate than other gas components. In one or more embodiments, a separation membrane is provided and includes a non-woven fabric backing, a porous support layer disposed on the non-woven fabric backing, a gutter layer disposed on the porous support layer, and one or more selective layers disposed on or above the gutter layer. Each of the selective layers independently contains a selective polymeric material, and at least one of the selective layers contains an ethylene vinyl alcohol polymeric material as the selective polymeric material.
