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.
Claims11
A nonwoven fabric for forming an oral pouched product, the nonwoven fabric comprising:
- a nonwoven fabric substrate;
- and
- a layer of diffusion restricting material on the nonwoven fabric substrate,
- wherein the diffusion restricting material is configured to provide a barrier to diffusion through the nonwoven fabric in aqueous environment,
- wherein the barrier to diffusion provides a temporary restriction to diffusion through the nonwoven fabric that is reducible by a chewing action, and
- wherein the layer of diffusion restricting material is a superabsorbent polymer comprising a water-soluble grade of sodium polyacrylate.
A nonwoven fabric for forming an oral pouched product, the nonwoven fabric comprising:
- a nonwoven fabric substrate;
- and
- a layer of diffusion restricting material on the nonwoven fabric substrate,
- wherein the diffusion restricting material is configured to provide a barrier to diffusion through the nonwoven fabric in aqueous environment,
- wherein the barrier to diffusion provides a temporary restriction to diffusion through the nonwoven fabric that is reducible by a chewing action, and wherein the layer of diffusion restricting material comprises a hydrophobic fluorocarbon material.
