Aspects herein are directed to a recyclable, asymmetrical-faced composite nonwoven textile suitable for use in apparel and other articles and methods of making the same. In example aspects, the asymmetrical-faced composite nonwoven textile includes a first face formed, at least in part from a first entangled web of fibers and an opposite second face formed, at least in part from a second entangled web of fibers. When incorporated into an article of apparel, the first face forms an outer-facing surface of the article of apparel, and the second face forms an inner-facing surface of the article of apparel. The first face includes features making it suitable to form the outer-facing surface such as resistance to abrasion, and the second face includes features making it suitable to form an inner-facing surface such as a soft hand.

The present disclosure relates to an absorbent article comprising a liquid pervious topsheet, a liquid impervious backsheet, an absorbent core disposed between the topsheet and the backsheet, and an intermediate layer disposed between the topsheet and the absorbent core, wherein the intermediate layer comprises a nonwoven which comprises a plurality of apertures, absorbent fibers, and ultrafine fibers. The nonwoven comprises the ultrafine fibers of about 3% to about 35% by weight of the nonwoven, and at least most of the plurality of apertures have a hydraulic diameter in the range of about 600 μm to about 4500 μm.

Provided are a core material for a vacuum insulation panel, a vacuum insulation panel, an insulated container, and a method for manufacturing a core material for a vacuum insulation panel. A core material for a vacuum insulation panel includes: an intermediate layer containing a polyester fiber or a polypropylene (PP) fiber; and an outer layer laminated on the intermediate layer; wherein the outer layer contains a thermoplastic fiber capable of thermal bonding.

A nonwoven fabric layered body includes a first nonwoven fabric layer including a crimped fiber (A), which is a fiber made of a thermoplastic polymer and which has an average crimp diameter of 800 μm or less; and a hydrophilic agent.

A method for forming an antimicrobial coating on a substrate is provided. The method comprises dissipating and entrapping (embedding) sulfonated copolymer particles in void spaces or interstices of fibers of a fabric forming an outer layer of a substrate. The sulfonated copolymer is selected from the group of perfluorosulfonic acid polymers such as sulfonated tetrafluoroethylene, polystyrene sulfonates, sulfonated block copolymers, polysulfones such as polyether sulfone, polyketones such as polyether ketone, sulfonated poly(arylene ether), and mixtures thereof. The fibers comprise a thermoplastic polymer having a melting point of less than 120° C., or 45-110° C., or 45-80° C. The sulfonated copolymer forms an antimicrobial coating layer for killing at least 90% microbes in the air within 30 minutes of contact with the coating.

A composite structure for interior lining includes a honeycomb structure having a first main surface and a second main surface, a first nonwoven layer of fibers bonded to the honeycomb structure at the first main surface or the second main surface. The honeycomb structure and the first nonwoven layer of fibers include thermoplastic polymeric materials. The honeycomb structure is provided from an uncut flat body and includes a plurality of honeycomb cells, and the honeycomb cells are delimited by walls. A film, including a thermoplastic polymeric material, is located in the composite structure between the first nonwoven layer of fibers and the honeycomb structure and/or bonded to the honeycomb structure at the main surface opposite to the main surface at which the first nonwoven layer of fibers is bonded to the honeycomb structure.
