A smokeless tobacco product includes smokeless tobacco and structural fibers. The structural fibers forming a network in which the smokeless tobacco is entangled. The structural fibers have a composition different from the smokeless tobacco. The tobacco-entangled fabric can have an overall oven volatiles content of at least 10 weight percent. In some embodiments, the structural fibers form a nonwoven network. In some embodiments, fibrous structures of the smokeless tobacco are entangled with the structural fibers.

A dry sheet for cleaning includes fiber layers, each arranged in front and back surface layers, and a nonwoven fabric layer between the fiber layers. The fiber layers are interlaced with the nonwoven fabric layer in an interlaced part which includes slightly interlaced parts and highly interlaced parts. The highly interlaced parts in the front surface layer are formed at almost same spots as those in the back surface layer. The front and back surface layers each include polyethylene terephthalate fiber having a diameter of 3.3 dtex or more at a rate of 80% or more. An area ratio of the highly interlaced parts to the front and back surface layers is 20 to 90%. The highly and slightly interlaced parts each extend in a direction almost perpendicular to a wiping direction of the sheet and are formed alternately and successively in the wiping direction.

The present invention generally relates to nonwoven structures and composites comprising such nonwoven structures, particularly structures incorporating foam, and methods of making and use thereof. One aspect of the invention is generally directed to composites comprising a nonwoven structure immobilized to foam, e.g., using adhesive, needling, or other techniques. The nonwoven structure may comprise any of a variety of fibers. In certain embodiments, the composite may be substantially thermally insulating and/or acoustic insulating. Other aspects of the present invention are generally directed to systems and methods for making such composites, methods of use of such composites, kits comprising such composites, and the like.

A hydroentangled fibrous structure. The hydroentangled fibrous structure can be incorporated into an absorbent article. Methods of forming a hydroentangled fibrous structure are also provided.

A fiber-bound engineered material is provided that imparts an intended characteristic at an intended relative location. A fiber layer is entangled with additional fibers in a manner to create a non-uniform engineered material. The lack of uniformity of a fiber-bound engineered material may be accomplished through manipulation of the fibers and/or through fiber binding a scrim. The fiber layer binds with additional fibers through entanglement such that a mechanical connection between the entangled fibers is provided. This entanglement allows the fibers to bind without supplemental adhesives, interlacing, or connections. Variations in the fibers and/or inclusion of scrim materials prior to entanglement allows for an intended characteristic (e.g., a functional characteristic) at an intended relative location (e.g., a position determined by an article to be formed therefrom).

Single layered nonwoven wound dressings containing (1) about 5% by weight to about 95% by weight (e.g., 5% to 95%) non-scoured, non-bleached greige cotton fibers, (2) about 5% by weight to about 95% by weight (e.g., 5% to 95%) bleached cotton fibers, and (3) about 5% by weight to about 60% by weight (e.g., 5% to 60%) hydrophobic fibers (e.g., polypropylene, nylon); all percentages adding up to 100 wt %. Also, multi-layered nonwoven wound dressings, containing (1) at least one inner layer containing (a) about 50% by weight to about 95% by weight (e.g., 50% to 95) non-scoured, non-bleached greige cotton fibers and (b) about 5% by weight to about 50% by weight (e.g., 5% to 50%) hydrophobic fibers, all percentages adding up to 100 wt %, and (2) at least one outer layer containing (a) about 5% by weight to about 95% by weight (e.g., 5% to 95%) non-scoured, non-bleached greige cotton fibers, (b) about 5% by weight to about 95% by weight (e.g., 5% to 95%) bleached cotton fibers, and (c) about 5% by weight to about 60% by weight (e.g., 5% to 60%) hydrophobic fibers (e.g., polypropylene, nylon); all percentages adding up to 100 wt %.

A method of manufacturing zoned webs can include providing a substrate and transferring the substrate in a machine direction. The method can include modifying the substrate to include a plurality of lanes to provide a modified substrate. The plurality of lanes can include a first lane and a second lane. The first lane can include a first zone and a second zone. The first zone can include an open area greater than an open area of the second zone. The second lane can include a third zone and a fourth zone. The third zone can include an open area greater than an open area of the fourth zone. The first lane and the second lane can be formed such that the first zone in the first lane is staggered in the machine direction from the third zone in the second lane. The method can also include slitting the modified substrate between adjacent lanes in the plurality of lanes to provide zoned webs.

A method for producing a gas diffusion layer for a fuel cell, including providing a fiber composition which includes carbon fibers and/or precursors of carbon fibers and subjecting the fiber composition to a method for producing a fibrous web. The method further includes consolidating the fibrous web by exposure to aqueous fluid jets to form a nonwoven, water used by the aqueous fluid jets having a conductivity of at most 250 microsiemens/cm at 25 C. If the fiber composition includes precursors of carbon fibers, the nonwoven is subjected to pyrolysis at a temperature of at least 1000 C.
