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 non-woven fabric for a pressure retarded osmosis membrane support and a pressure retarded osmosis membrane comprising the same. More specifically, the present invention has: remarkably excellent water permeability and pressure resistance; a polymeric solution, coated on a non-woven fabric, with minimum permeability into the non-woven fabric and minimum draining to a rear side thereof; minimum a loss of an osmosis membrane thanks to excellent mechanical strength.
