The present invention relates to a packaging material for use in an oral pouched snuff product in order to enclose a smokeless tobacco composition or non-tobacco composi¬tion. The packaging material is a saliva-permeable nonwoven comprising carded fibres, whereof 0%-95% of the carded fibres are of a first type and 5%-100% are of a second type. The fibres of the first type are cellulose-based staple fibres. The fibres of the second type are thermoplastic fibres, comprising a first component and a second component, the second component having a lower melting temperature than the first component. The packaging material is bonded by means of at least partial melting and/or softening of the second component of the fibres of the second type and has a smooth-calendered surface.

The present invention also relates to an oral pouched snuff product comprising such a packaging material.

A fibrous structure including one or more nonwoven material layers comprising a fiber matrix, where the fiber matrix comprises polymeric binder fibers having a softening and/or melting temperature of about 190° C. or greater, where the article is adapted to withstand temperatures of about 190° C. or greater while in use; and where the article is a thermoacoustic insulation material.

A cushion or pad device is provided. The device comprises at least one layer of nonwoven material defining a volume with length, width, and depth dimensions, wherein the vertically lapped nonwoven material comprises at least one bulk fiber, wherein the bulk fiber comprises a thermoplastic polyester; and at least one elastomeric binder fiber. Methods of preparing the cushion or pad device are also provided.

Methods of treating fibers comprising a polymer including at least one of a vinyl acetate moiety or a vinyl alcohol moiety, and resulting fibers or the products comprising the resulting fibers are disclosed. In an example embodiment, a fiber having a surface region and an interior region, includes a polymer comprising at least one of a vinyl acetate moiety or a vinyl alcohol moiety chemically modified with a modification agent. The fiber has a transverse cross-section including the interior region comprising the polymer having a first degree of modification and the surface region comprising the polymer having a second degree of modification greater than the first degree of modification.

A nonwoven fabric having improved fluid management properties is provided. The fabric is formed of a plurality of the fibers that include at least an aliphatic polyester polymer. The aliphatic polyester polymer defines at least a portion of an outer surface of the fibers, and includes a natural-based finish composition that is adhered thereto.

Methods of treating fibers comprising a polymer including at least one of a vinyl acetate moiety or a vinyl alcohol moiety, and resulting fibers or the products comprising the resulting fibers are disclosed. In an example embodiment, a method of treating fibers includes contacting a surface of a fiber comprising the polymer with a modification agent to chemically modify at least a portion of the polymer with the modification agent in a region of the fiber comprising at least the surface of the fiber to form a modified fiber.

A disposable absorbent pant having an elasticized belt structure including the stretch laminate is disclosed. The stretch laminate may include a first layer; a second layer; and an elastic member disposed between the first layer and the second layer. The first layer may include a nonwoven web material bearing a pattern of thermal bonds, including a plurality of bonds each having a length and a width, the length being oriented perpendicularly to the stretch direction and being greater than the width. The elastic member may be joined with the first layer and the second layer while pre-strained in the stretch direction; when the stretch laminate is in a relaxed condition, at least the first layer may include a plurality of gathers including elongate ridges and valleys oriented transversely to the stretch direction. A is also disclosed.

Disclosed herein are nonwoven webs comprising a nonwoven substrate and a binder comprising a polysaccharide. In one embodiment, the polysaccharide can comprise poly alpha-1,3-glucan, a poly alpha-1,3-glucan ether compound as disclosed herein, a poly alpha-1,3-glucan ester compound as disclosed herein, a graft copolymer comprising a backbone comprising dextran and poly alpha-1,3-glucan side chains, a crosslinked graft copolymer comprising a backbone comprising dextran and poly alpha-1,3-glucan chains, or a mixture thereof. Also disclosed are articles comprising the nonwoven webs, and methods of making the nonwoven webs.

Described herein is a thermoplastic core-sheath fiber. The thermoplastic core-sheath fiber comprises a core having a coextensive sheath layer disposed thereon, wherein the core comprises a first polymeric resin and an electrostatic charge enhancing additive, and the sheath layer comprising a second polymeric resin, with the proviso that if the second polymeric resin comprises poly(4-methyl-1-pentene), then the second polymeric resin does not comprise 100 wt % of poly(4-methyl-1-pentene). These thermoplastic core-sheath fibers can be used in filtering applications.

A polymeric material that includes a thermoplastic composition containing a continuous phase that includes a polyester and a copolyetherester elastomer is provided. The copolyetherester elastomer is dispersed within the continuous phase in the form of discrete domains. A porous network is defined within the thermoplastic composition that includes a plurality of nanopores.
