Smokeless tobacco products suitable for oral consumption are provided. The smokeless tobacco products include a tobacco composition and at least one fibrous structure enclosing at least a portion of the outer surface of the tobacco composition such that the fibrous structure and the tobacco composition form a cohesive structure capable of maintaining cohesion when placed in an oral cavity, wherein the fibrous structure includes one or more of (i) a warp knitted structure; (ii) a plurality of reinforcing fibers attached to the tobacco composition; (iii) a braided sleeve; and (iv) a spacer fabric. A process for preparing a smokeless tobacco product adapted for oral consumption is also provided, the process including the step of enclosing at least a portion of the outer surface of a tobacco composition with a fibrous structure to form a composite structure.

The smokeless tobacco product of claim 1, further comprising an edible film, wherein the edible film at least partially encapsulates the tobacco composition. 14. The smokeless tobacco product of claim 1, further comprising at least one edible film or fabric sheet positioned adjacent to the tobacco composition to form a multi-layer structure, and wherein a plurality of reinforcing fibers are positioned on the surface of the multi-layer structure and attached thereto. 15. A process for preparing a smokeless tobacco product adapted for oral consumption, comprising the step of enclosing at least a portion of the outer surface of a tobacco composition with a fibrous structure to form a composite structure capable of maintaining cohesion when placed in an oral cavity, wherein the fibrous structure comprises one or more of (i) a warp knitted structure; (ii) a plurality of reinforcing fibers attached to the tobacco composition through a tailored fiber placement (TFP) process; (iii) a braided sleeve; and (iv) a spacer fabric. 16. The process of claim 15, wherein the tobacco composition comprises at least one of a cut, ground, pelletized, particulate, granular, shredded, reconstituted, extruded, cast, or compressed tobacco sheet material. 17. The process of claim 15, wherein the tobacco composition is in the form of a compressed tobacco sheet. 18. The process of claim 15, wherein the fibrous structure comprises fibers made from a material selected from the group consisting of alginate, protein, cotton, nylon, viscose, polyester, acrylics, flax, jute, bamboo, rayon, polyvinyl alcohol, starch, polyurethane, cis-polyisoprene, polyanhydride, polybutylene succinate, hybrid yarns formed containing glass fiber, and copolymers and blends thereof. 19. The process of claim 15, wherein the fibrous structure comprises fibers made from a cellulosic material or an aliphatic polyester selected from polylactic acid and polyhydroxyalkanoates. 20. The process of claim 15, wherein the fibrous structure encloses at least about 50% of the outer surface area of the tobacco composition. 21. The process of claim 15, wherein the fibrous structure encloses at least about 90% of the outer surface area of the tobacco composition. 22. The process of claim 15, wherein the fibrous structure comprises a warp knitted structure and the enclosing step comprises placing the tobacco composition within a cavity formed within the warp knitted structure and compressing the warp knitted structure around the tobacco composition. 23. The process of claim 15, wherein the fibrous structure comprises a plurality of reinforcing fibers attached to the tobacco composition through a tailored fiber placement (TFP) process that comprises the step of stitching each reinforcing fiber to the tobacco composition. 24. The process of claim 15, wherein the fibrous structure comprises a braided sleeve, and wherein the enclosing step comprises placing the tobacco composition within a cavity formed within the braided sleeve and compressing the braided sleeve around the tobacco composition. 25. The process of claim 15, wherein the fibrous structure comprises a spacer fabric, and the enclosing step comprises placing the tobacco composition within the spacer fabric and collapsing the spacer fabric around the tobacco composition. 26. The process of claim 25, wherein the spacer fabric comprises two fabric layers joined together by a plurality of intermediate fibers and defining voids between the two fabric layers, and wherein the enclosing step comprises placing the tobacco composition within the voids of the spacer fabric. 27.
