The invention provides migration resistant batting that includes a nonwoven web comprising a first surface parallel to a second surface, and a fiber mixture that includes: 35 to 65 wt % synthetic polymeric fibers having a denier of less than or equal to 1.0, wherein 50 to 100 wt % of said synthetic polymeric fibers are siliconized fibers; 10 to 30 wt % spiral-crimped synthetic polymeric fibers having a length of greater than or equal to 60 mm, wherein 50 to 100 wt % of said spiral-crimped synthetic polymeric fibers are siliconized fibers; 20 to 50 wt % elastomeric fibers having a denier between 2.0 and 7.0; and 5 to 25 wt % synthetic binder fibers having a denier of 1.5 to 4.0, said binder fibers have a bonding temperature lower than the softening temperature of the synthetic polymeric fibers, wherein said first and second surfaces comprise a cross-linked resin. Also provided are articles comprising the batting and methods of making the batting.

A device for treating a damaged tissue includes an expandable scaffold positionable in a portion of a luminal tissue structure of a mammal; and maintained via stent technology, wherein the scaffold is comprised of electrospun fibers composed of a biodegradable compound. The scaffold serves as a temporary template that allows the tissue to be rebuilt.

The present invention provides a non-woven fabric for supporting a solid electrolyte in which heat-fusible composite fibers with a crimp are contained in an amount of not less than 60 mass % and not more than 100 mass % and are heat-fused, and a solid electrolyte sheet. The non-woven fabric for supporting a solid electrolyte is excellent in process performance, is satisfactorily filled with a solid electrolyte, is suitable for achieving a thin solid electrolyte sheet, and has few hole defects. The solid electrolyte sheet is excellent in self-sustainability and flexibility.

A spunbond nonwoven laminate has a plurality of stacked spunbond nonwoven layers, namely at least two and at most four spunbond nonwoven layers that have crimped continuous filaments or consist of crimped continuous filaments. The degree of crimping of the filaments is different in each of these spunbond nonwoven layers, and each of the crimped filaments of the spunbond nonwoven layers has a crimp with at least two, preferably at least three, and more preferably with at least four loops per centimeter of length. The crimped filaments of the spunbond nonwoven layers are multicomponent filaments, particularly bicomponent filaments, with a first plastic component and a second plastic component present in the respective filament in a proportion of at least 10 wt %.

A non-woven electret fibrous web for electrostatic adsorption and odor elimination and the preparation process thereof. In certain exemplary embodiments, the non-woven electret fibrous web includes a multiplicity of electret fibers, at least one of a plurality of photo-catalytic fibers or a plurality of multi-component fibers; and optionally, at least one of a plurality of chemically-active particulates, a plurality of carbon-based fibers, or a plurality of mono-component thermoplastic fibers. In other exemplary embodiments, carding and cross-lapping or air-laying processes are disclosed for making nonwoven fibrous webs including electret fibers and one or more of photocatalytic fibers, chemically-active particulates, multi-component fibers, mono-component thermoplastic fibers, or carbon-based fibers. In some exemplary embodiments, exemplary non-woven electret fibrous webs of the disclosure exhibit superior gas permeation characteristics, high adsorption characteristics for airborne contaminants, as well as an odor elimination function.

A hollow fiber that extending along at least a portion of the fiber along a longitudinal axis thereof and is defined by an interior wall is provided. Through selective control over the manner in which it is formed, the present inventors have discovered that the hollow fiber can exhibit a unique combination of a high void fraction and small fiber size that makes it particularly suitable for use in certain applications, such as in nonwoven webs for absorbent articles.
