THERMOPLASTIC NON-WOVEN TEXTILE ELEMENTS
A non-woven textile may be formed from a plurality of thermoplastic polymer filaments. The non-woven textile may have a first region and a second region, with the filaments of the first region being fused to a greater degree than the filaments of the second region. A variety of products, including apparel (e.g., shirts, pants, footwear), may incorporate the non-woven textile. In some of these products, the non-woven textile may be joined with another textile element to form a seam. More particularly, an edge area of the non-woven textile may be heatbonded with an edge area of the other textile element at the seam. In other products, the non-woven textile may be joined with another component, whether a textile or a non-textile.
Liquid Barrier Nonwoven Fabrics with Ribbon-Shaped Fibers
A nonwoven fabric useful as a component in a personal hygiene product and a nonwoven personal hygiene component, which is substantially free or free of non-ribbon shaped (e.g., round-shaped) spunbond fibers and includes a meltblown layer between and in direct contact with ribbon-shaped spunbond layers. The meltblown layer has a basis weight of at least about 0.008 gsm and not greater than about 5 gsm, and the nonwoven fabric or component has a basis weight of at least about 8 gsm and not greater than about 40 gsm, a pore size of less than or equal to about 27 microns when measured at 10% of cumulative filter flow. The nonwoven fabric also can have a low surface tension liquid strike through flow of less than 0.9 ml per second, a ratio of low surface tension liquid strike through flow to air permeability of greater than or equal to about 0.016, or both. Personal hygiene articles can incorporate the nonwoven fabric or component.

SOUND-ABSORBING MATERIAL NONWOVEN FABRIC, SOUND-ABSORBING MATERIAL, AND METHOD FOR PRODUCING SOUND-ABSORBING MATERIAL NONWOVEN FABRIC
A sound-absorbing material nonwoven fabric includes: 30 to 80 mass % of short fibers A having a fineness of 0.4 to 0.9 dtex; and 20 to 70 mass % of short fibers B having a fineness of 1.1 to 20.0 dtex. A carding passage coefficient of the short fibers A calculated from equation (1) is in a range of 15 to 260. The equation (1) is carding passage coefficient=(fineness×strength×√elongation percentage×√number of crimps×√crimping degree)/(fiber length).

Shaped nonwoven
A nonwoven fabric. The nonwoven fabric can include a first surface and a second surface and a visually discernible pattern of three-dimensional features on one of the first or second surface. Each of the three-dimensional features can define a microzone comprising a first region and a second region. The first and second regions can have a difference in values for an intensive property, and wherein in at least one of the microzones, the first region exhibits a Contact Angle of greater than 90 degrees, as measured by the Contact Angle Test Method detailed herein, and the second region exhibits a Time to Wick of less than 10 seconds, as measured by the Time to Wick Test Method detailed herein.

PROCESS FOR PRODUCING POLYVINYL ALCOHOL ARTICLES
The present invention provides a process for modifying the surface of a polyvinyl alcohol film or fabric by applying heat and pressure to the film or fabric to increase the moisture on the surface which is held by the fabric and to coalesce the surface fibers and reduce the porosity of the surface.

Fiber-wrapped smokeless tobacco product
A fiber-wrapped smokeless tobacco product includes smokeless tobacco and a plurality of polymeric fibers surrounding the smokeless tobacco. The polymeric fibers can have a basis weight of 5 gsm or less and a diameter of less than 100 microns. In some cases, the polymeric fibers are melt-blown polymeric fibers. In some cases, the polymeric fibers are centrifugal force spun polymeric fibers. A method of preparing a fiber-wrapped smokeless tobacco product includes melt-blowing or centrifugal force spinning a plurality of polymeric fibers to create an polymer deposition zone and passing a body comprising smokeless tobacco through the polymer deposition zone. In some cases, an electrostatic charge can be applied to the plurality of polymeric fibers, the body, or a combination thereof. In some cases, a spin is applied to the body when passing through the polymer deposition zone.
