Abstract: A nonwoven fabric for manufacturing an oral pouched product, where the nonwoven fabric is chewable to increase its liquid permeability. When the nonwoven fabric is used to form a pouch, it may thus control the release of substances from within the pouch. The nonwoven fabric can be formed by applying a diffusion restricting treatment to a base nonwoven fabric. The diffusion restricting treatment may include any of (a) incorporating a digestible compound; (b) incorporating a superabsorbent polymer; (c) incorporating a hydrophobic material; and (d) forming a deformable barrier layer.

Abstract: A product for oral delivery of a substance in which the substance is retained with a layered structure of nonwoven materials that provides structural integrity capable of withstanding a chewing action, together with a desirable mouth feel and appealing product form factor. The substance may be a gel material that is held within a plurality of layers of nonwoven fabric that are secured together as a consolidated web by physical consolidation technique such as hydroentanglement, stitching, embossing, needle felting/punching.

Abstract: A nonwoven fabric for use as packaging in an oral pouched product, where the nonwoven fabric comprises a web of chemically bonded staple fibres in which a relative proportion of staple fibres and a binder is selected in conjunction with a density of the fabric to strike an optimal balance in achieving a fabric that provides a soft (e.g. low friction) mouthfeel, a wet strength capable of withstanding manipulation in a user's mouth (e.g. chewing, sucking or the like), and a resistance to unwanted leaching or leaking of flavouring or other fine particle substances used in modern oral products.

Abstract: A chewable product for oral delivery of a substance. The chewable product is an essentially homogenous portion of nonwoven fabric impregnated with the substance. For example, the chewable product may comprise a nonwoven fabric substrate having a matrix of interleaved fibres. The substance is held within the matrix and releasable therefrom by a chewing action. The nonwoven fabric substrate thus provides a frame for carrying the substance that is both resistant to chewing action (i.e. does not disintegrate when chewed, bitten or sucked) and capable of releasing the substance. The nonwoven fabric substrate may be formed by passing an initial web through a needle loom. The substance may be connected to fibres in the matrix by a binder.
