Abstract
A method of manufacturing a polymer pore filter for filtering kaolin particles from an aqueous medium, comprising the steps of: coating and partially impregnating at least one face of a woven polyester textile substrate with a polyether based polyurethane polymer; coagulating the polymer by heating in the presence of a coagulant; and forming the polymer simultaneously with or immediately after coagulation.
