The present invention is directed to fabrics for paper making machines that are rendered contamination resistant, maintain good permeability, and enhanced seam strength as a result of a durable coating that lasts the entire life of the fabric. A polyurethane based coating containing a fluorochemical will render the fabric contamination resistant over the entire fabric lifetime. It has been found that optical brighteners and titanium dioxide also enhance fabric appearance.
