1. International (WO) Patent App. No: PCT/EP2021/060597

NONWOVEN FABRIC FOR ORAL POUCHED PRODUCT, AND METHODS OF MANUFACTURING A NONWOVEN FABRIC
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. 27 April 2020

NONWOVEN FABRIC FOR ORAL POUCHED PRODUCT, AND METHODS OF MANUFACTURING A NONWOVEN FABRIC
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. 5 February 2021
3. International (WO) Patent Application No: PCT/EP2021/082091

CHEWABLE PRODUCT FOR ORAL DELIVERY OF A SUBSTANCE, AND METHOD OF MANUFACTURING THE SAME
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. 27 November 2020

NONWOVEN FABRIC; POUCHED PRODUCT AND RELATED METHODS
The present invention provides a nonwoven fabric comprising a non-fibrous binder having certain solubility characteristics. It also provides a pouched product, the fabric and contents of which have certain solubility characteristics. Related methods are also disclosed. 5 February 2021
5. United Kingdom (GB) Patent Application No: 2317246.3

NONWOVEN PRODUCT FOR ORAL DELIVERY OF A SUBSTANCE, AND METHOD OF MANUFACTURING THE SAME
The invention provides 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. In one embodiment, the substance is 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. 10 November 2023
6. United Kingdom (GB) Patent Application No: 2411360.7

PRODUCT FOR ORAL DELIVERY
A product for oral delivery of a substance comprising an active agent, the product comprising: a first fabric; and the substance adhered to the first fabric; wherein the substance is adhered to the first fabric in the form of discrete dots. At its most general, the invention relates to the adherence of a substance comprising an active agent for oral delivery onto a fabric, the substance adhered onto the fabric in the form of discrete dots. 1 August 2024

PRODUCT FOR ORAL DELIVERY AND MANUFACTURE THEREOF
The present invention relates to a method of manufacturing a product for oral delivery of an active substance. The product comprises a consolidated fabric (e.g. a chemically bonded fabric) and the active substance. The method comprises the steps of: providing a fabric web; applying a first binder solution to the fabric web to provide the chemically bonded fabric; heating the chemically bonded fabric to dry the chemically bonded fabric; allowing the chemically bonded fabric to cool; and subsequently, applying a second binder containing the active substance to the chemically bonded fabric. In contrast to conventional pouched products for oral delivery of substances, where the active substance is contained within a pouch composition within a cavity defined by the fabric pouch, the present invention provides an active substance on/in the base fabric itself (e.g. the fabric used to provide the pouched product), thereby reducing the distance that the active substance has to diffuse through the product and the user’s oral cavity, which can provide the user with a more immediate flavour hit. 9 January 2025

NONWOVEN FABRIC FOR ORAL POUCHED PRODUCT, AND METHODS OF MANUFACTURING A NONWOVEN FABRIC
The present invention relates to a nonwoven fabric for use in manufacturing oral pouched products and particularly, although not exclusively, to a nonwoven fabric with enhanced sieving properties to be suitable for use with modern oral products. In one aspect, the nonwoven fabric comprises a chemically bonded web of staple fibres, wherein the staple fibres comprise: a first component of fibres with a linear density equal to or greater than 0.9 dtex; and a second component of fibres with a linear density of less than 0.9 dtex. In another aspect, the nonwoven fabric comprises a chemically bonded web of staple fibres, wherein the staple fibres comprise: a first component of non-splitable fibres; and a second component of split fibres. The first component of non-splitable fibres may have a linear density equal to or greater than 0.9 dtex, the second component of split fibres may have a linear density of less than 0.9 dtex. In a further aspect, a method of manufacturing a nonwoven fabric for forming an oral pouched product is provided, the method comprising: mixing staple fibres that comprise splitable fibres and non-splitable fibres; splitting a proportion of the splitable fibres to form split fibres; forming a web of the staple fibres, the web comprising: a first component of the non-splitable fibres; and a second component of the split fibres; and applying a binder to the web to bond the staple fibres together. 24 January 2025

1. International (WO) Patent Application No: PCT/EP2021/085767

FILTER MATERIAL (CARBON GRANULES)
The present invention relates to protective materials and particularly, although not exclusively, to materials suitable for use in CBRN (Chemical, Biological, Radiological and Nuclear) protective fabrics or filtration fabrics, and methods for manufacturing such materials. The present inventors have found that by control of the adhesive with which carbon particles are adhered to fabric layers which sandwich it, the efficacy of adhesion can be improved and thus the efficacy of the protective qualities of the material increased. In particular, the locations of dots of adhesive used has been found to be important in securing these advantages. 15 December 2020
