A compression bandage that is formed by the assembling of a self-adhesive nonwoven based on short conjugate fibers which have been crimped and of an elastic material, the effectiveness of which increases over time. The bandage can be used, alone or in a bilayer compression system, for the prevention or treatment of venous pathologies or lymphedema.

A compression bandage formed by the assembling of a nonwoven based on short conjugate fibers which have been crimped and of a nonelastic material. The compression bandage can be used in a bilayer compression system, in particular for the prevention or treatment of venous pathologies.

A multi-faceted family of non-woven webs that can take the form of a filter media, an adaptable forming process and a machine capable of making the range of media are disclosed. The filter medium can have a first surface and a second surface defining a thickness. The medium can comprise a region having a gradient. Such a gradient is formed by having a medium wherein the concentration of a fiber, a property or other component varies from one surface to the next surface. The gradient region of the media can comprise the entire thickness of the medium or can comprise a region that comprises a portion of the media thickness. The media are characterized by the presence of a continuous change of the fiber concentration or property within the region. A non-woven web can also be made comprising a planar fiber structure having a gradient. Such a web can comprise fibers having diameters that can range from 1 to 40 microns and a second fiber having a diameter that can range from 0.5 microns to about 5 microns. The gradient can change in the cross machine (x-dimension) or across the thickness (z-dimension) increasing or decreasing in either direction. The media of the invention can be used in a variety of applications for the purpose of removing particulates from a variety of gas use on liquid media. Further, the filtered medium of the invention used in a variety of filter element types including flat media, pleated media, flat panel filters, cylindrical spin-on filters, z media pleated filters and other embodiments wherein the gradient provides useful properties. Methods or processes or an apparatuses for forming a nonwoven medium comprising controllable characteristic within the medium are disclosed. The term medium (plural media) refers to a web made of fiber having variable or controlled structure and physical properties.

Use of polymer composition comprising a first propylene polymer A and a second propylene polymer B for producing crimped multicomponent fiber having a side by side cross-sectional configuration.

The present invention refers to a nonwoven web with multicomponent fibers having at least a first and a second component which differ from each other in color. The nonwoven web is pattern bonded to obtain bonded areas have a different color versus the unbonded areas.

A nonwoven substrate comprising a polyolefin and an engineering thermoplastic polymer. The engineering thermoplastic polymer may be present in the nonwoven substrate at a level of between about 1% and about 20% by weight of the nonwoven substrate. The layer of fibers is free of a compatibilizer.

A lithium-ion secondary battery separator resolves defects of a non-woven fabric separator which is not suitable for use in such a battery. The separator is thin and does not short-circuit and has excellent electrolyte retainability and rate characteristics. The separator includes a composite of a non-woven fabric having a basis weight of 2 to 20 g/m.sup.2 formed from fibers of a thermoplastic material having an average fiber diameter of 5 to 40 m and ultra-microfibers having an average fiber diameter of 1 m or less in an amount of to 3 times the mass of the non-woven fabric. The composite has a thickness of 10 to 40 m after heat-pressing treatment under conditions that the non-woven fabric has a glossiness (JIS Z 8741) measured at 60 in the range of 3 to 30 and a thickness of 10 to 40.

The invention relates to nonwoven fabric sheets containing crimped multicomponent fibers.

Nonwoven fabrics are provided that include a plurality of crimped bicomponent fibers having a first component comprising a first polymeric material comprising a first polymer or a first polymeric blend and a second component comprising a second polymeric material, in which the second polymeric material comprises a second polymeric blend of (i) at least one polypropylene polymer, (ii) at least one polyethylene polymer, and (iii) at least one compatibilizer comprising or consisting of at least one polypropylene-polyethylene copolymer.

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.
