  • Patent number: 11401658
    Abstract: Disclosed is a two layered belt useful in the manufacture of tissue products comprising a first woven layer and a second nonwoven layer joined together in a laminated arrangement. The woven layer typically forms the machine contacting layer of the belt and is woven from a highly abrasion resistant material, while the nonwoven layer contacts the nascent tissue web. The woven layer may be provided with valleys and ridges that the nascent web is molded into, while the nonwoven layer may be provided with elements that impart a visually aesthetic pattern to the web. In this manner the belt may be useful in the production of products having desirable physical properties resulting from molding into the woven fabric while also being visually pleasing to the user.
