Abstract

The invention relates to a wet-fast nonwoven, preferably a fiber paper, which comprises fibers from a cellulose-containing material and fibers from a thermoplastic material welded firmly together at their points of intersection. The fibers from the cellulose-containing material are preferably hemp fibers while the fibers from the thermoplastic material are preferably fibers from polypropylene, polyester or polyamide. The fibers are interlinked under the action of pressure and/or heat, especially using a pair of heated calender rolls. The nonwoven or the fiber paper is especially used to reinforce food casings based on regenerated cellulose, especially in artificial cellulose hydrate-based sausage skins.
