Latest Patents
Stephen H Tse's latest patents include methods for the manufacture of wetlaid nonwoven webs. One patent describes a method for forming a fabric web by wet-laying fibers on paper-making equipment. This web comprises staple length natural or synthetic fibers and optionally wood cellulose papermaking fibers, along with an adsorbed polymeric surface active agent. The method involves creating an aqueous fiber furnish with a polymeric surfactant that has both hydrophilic and hydrophobic groupings per molecule. The surfactant is adsorbed by the fibers, enhancing the finished web's properties.
Another patent outlines a method for forming a fibrous web by wet-laying fibers on paper-making equipment. This web consists of staple length natural or synthetic fibers and wood cellulose paper-making fibers. In this method, a water furnish of the fibers is made up with an associative thickener, eliminating the need for a conventional surfactant. A preferred associative thickener is a urethane block copolymer with a polyethylene glycol backbone, which acts as both a surfactant and thickener. This innovative approach results in excellent consistency of the water and fiber dispersion at relatively low viscosity, allowing for rapid drainage of water and uniform web formation.
