NON-WOVEN FABRIC FOR A PRESSURE RETARDED OSMOSIS MEMBRANE SUPPORT AND PRESSURE RETARDED OSMOSIS MEMBRANE COMPRISING THEREOF

摘要

The present invention relates to a fabric for a pressure retarded osmosis membrane support and a pressure retarded osmosis membrane comprising the fabric for the pressure retarded osmosis membrane support, and more specifically, to a fabric for a pressure retarded osmosis membrane support which minimizes damages of the osmosis membrane by having remarkably excellent water permeability and pressure resistance, minimizing fabric penetrating properties and reverse side draining properties of a polymer solution coated on the fabric, and retaining excellent mechanical strength, and a pressure retarded osmosis membrane comprising the fabric for the pressure retarded osmosis membrane support. A fabric for a pressure retarded osmosis membrane support according to the present invention comprises wefts (100) and warps (110), and satisfies the following conditions (1) and (2) at the same time: (1) 200 to 350 numbers of intersecting points (openings) (120) of wefts and warps within a range of width (2.54 cm) X length (2.54 cm); and (2) 10 deniers to 25 deniers of fineness.
