Inherently secured aerogel composites
Embodiments of the present invention describe secured fiber-reinforced aerogels and laminate structures formed therefrom. In one embodiment a laminate comprises at least one fiber-reinforced aerogel layer adjacent to at least one layer of fiber containing material wherein fibers from said at least one fiber-reinforced aerogel layer are interlaced with fibers of said at least one fiber-containing material. In another embodiment a laminate comprises at least two adjacent fiber-reinforced aerogel layers wherein fibers from at least one fiber-reinforced aerogel layer are interlaced with fibers of an adjacent fiber-reinforced aerogel layer.
Shingle with reinforced nail zone and method of manufacturing
A method of making a laminated shingle is provided. The method includes coating a shingle mat with roofing asphalt to make an asphalt-coated sheet, adhering a reinforcement member to a portion of the asphalt-coated sheet, covering the asphalt-coated sheet, and optionally covering the reinforcement member, with granules to make a granule-covered sheet, dividing the granule-covered sheet into an overlay sheet and an underlay sheet, wherein the overlay sheet has a tab portion normally exposed on a roof and a headlap portion normally covered-up on a roof, the headlap portion having a lower zone adjacent the tab portion and an upper zone adjacent the lower zone, and wherein the reinforcement member is adhered to the lower zone of the headlap portion and laminating the overlay sheet and the underlay sheet to make the laminated shingle.
Low Linting Imaged Hydroentangled Nonwoven Composite
Hydroentangled composites having a wide variety of uses (e.g., personal hygiene articles, facers for fenestration absorbent patches on surgical drapes, facers on absorbent surgical drapes, etc.) are provided. The hydroentangled composite includes at least two nonwoven webs hydroentangled together. The hydroentangled composite may have a three-dimensional structure. Additionally, the at least two nonwoven webs may have different bonding levels and/or lint levels.
Hydroembedded film-based composites
A substrate has an elastomeric film having surfaces and a nonwoven web having fibers, wherein a plurality of fibers is partially embedded in one surface of the film. In addition, a substrate has an elastomeric film and a nonwoven web having fibers, wherein a plurality of fibers is partially embedded in one surface of the film, and wherein the substrate is essentially free of adhesives and film-based microfibers. A method for making a film/nonwoven composite includes providing an elastomeric film traveling in a machine direction; providing a nonwoven web traveling in the machine direction in face-to-face contact with the film, wherein the nonwoven web includes fibers; and impinging the elastomeric film with hydro jets such that at least some of the fibers become embedded in the film.
Composite material for fluid flow management
A composite material (and its manufacture) is described that has (i) a first layer comprising an absorbent fiber material that is in contact with the area of use on its first side, (ii) a second layer comprising an absorbent material, said second layer being arranged on the second side of said first layer, wherein a plurality of channels extends through the entire first layer, from said first side to said second side thereof, and further extends into at least a portion of said second layer. This composite is of particular use in wound treatment.
NON-FLAMMABLE THERMAL INSULATING COMPOSITE SUBSTRATE FOR MOTOR VEHICLES AND PRODUCTION METHOD
Disclosed is a non-flammable thermal insulating composite substrate for motor vehicles including: a textile component constituted by a layer of needle-sewn non-woven fabric composed of a percentage of pre-oxidized polyacrylonitrile fiber included between 40% and 70%, preferably 58% and of the remaining percentage of polyethylene glycol-terephthalate fiber, the textile component having weight preferably 400 gr/m.sup.2; and a barrier fixed to the textile component using a spreading process, constituted by a thermoplastic resin based on low density polyethylene added with non-halogen flame retardants, the barrier having weight preferably 100 gr/m.sup.2. The composite substrate has the following features: a thickness included between 2 mm and 5 mm, preferably 3.8 mm; a weight included between 300 gr/m.sup.2 and 700 gr/m.sup.2, preferably 500 gr/m.sup.2; odorless; no emission of fumes; dimensionally stable, even at heatstroke, with a maximum variation of 1%; and non-flammability.
Methods and apparatuses for making elastomeric laminates with elastic strands unwound from spools on surface unwinders
The present disclosure relates to methods for assembling elastomeric laminates, wherein elastic material may be stretched and joined with either or both first and second substrates. First spools are rotated to unwind first elastic strands from a first unwinder in a machine direction. The first elastic strands are positioned between the first substrate and the second substrate to form an elastomeric laminate. Before the first elastic strands are completely unwound from the rotating first spools, second spools are rotated to unwind second elastic strands from a second unwinder. Subsequently, the advancement of the first elastic strands from the first unwinder is discontinued. Thus, the elastomeric laminate assembly process may continue uninterrupted while switching from an initially utilized elastic material drawn from the first spools to a subsequently utilized elastic material drawn from the second spools.
METHOD OF MAKING A SPUNBOND LAMINATE
A spunbond nonwoven laminate has a first spunbond nonwoven layer having crimped filaments formed by a first component on an outer surface of the filaments of the first layer consisting or substantially consisting of a polyolefin and a second component consisting or substantially consisting of a plastic having a higher melting point than the polyolefin of the first component of the filaments of the first layer. A second outermost spunbond nonwoven layer on the first layer having filaments as a cover layer and formed by a first component on an outer surface of the filaments of the second layer consisting or substantially consisting of a polyolefin, and a second component consisting or substantially consisting of a plastic having a higher melting point than the polyolefin of the first component of the filaments of the second layer.
