A nanofiber sheet includes: a substrate layer; and a nanofiber layer located on one surface side of the substrate layer and containing nanofibers of a polymer compound. A peripheral edge of the nanofiber layer has a thickness of from 0.1 to 10 μm. The nanofiber layer includes a gradation region having a thickness that gradually increases inward from the peripheral edge. The distance W1 between the peripheral edge of the nanofiber layer and a maximum thickness portion where the thickness becomes the greatest in the gradation region is at least 3 mm. A nanofiber sheet manufacturing method involves depositing nanofibers onto a collecting unit by moving at least either a nozzle or the collecting unit, to thereby manufacture a predetermined nanofiber sheet including a gradation region.

A structure for secure containment of information (SSCI) that is in the form of a laminate which includes at least two layers. The laminate is constructed to contain information such as a code, serial number, informational feature, encryption key or personal identification number (PIN). The information is located between the layer of the laminate such that the code, serial number, informational feature, encryption key, or PIN is not detectable from outside the laminate. The SSCI is configured to provide access and expose the code, serial number, informational feature, encryption key, or PIN by delaminating at least one layer, thereby indicating that tampering has occurred to the laminate. The SSCI can also function as a public key or private key for a blockchain, to provide access to a physical lock or to provide account access to claim financial value.

A trim component for a vehicle interior includes first and second skin layers, a core layer sandwiched between the first and second skin layers with the core layer having first and second sides, a first thermoplastic adhesive material including a polyamide disposed between the first skin layer and the core layer to adhere the first skin layer to the first side of the core layer, and a second thermoplastic adhesive material including a polyamide disposed between the second skin layer and the core layer to adhere the second skin layer to the second side of the core layer.

This disclosure relates to using polyester films on building boards to enable improved surface coatings. The polyester film is preferably applied to a glass mat via an adhesive to form a laminate. This laminate is then bonded to the exterior surface of a gypsum board. The polyester film is advantageous because it allows for exterior surface coatings to be applied. In one embodiment, an exterior acrylic coating is applied to the polyester film. Boards constructed in accordance with this disclosure allow for exterior finishings to be achieved without the need for excessive finishing materials or steps.

A process for forming a moldable, uncured nonwoven composite containing forming a outermost nonwoven layer, forming a structural nonwoven layer, needling the structural nonwoven layer and the outermost nonwoven layer together from both the outer surface of the outermost nonwoven layer and the second surface of the structural nonwoven layer, applying an uncured, water-based thermosetting resin having a cure temperature of at least about 160° C. to the second surface of the structural nonwoven layer, and at least partially drying the uncured, wet nonwoven composite. Heat and pressure may be applied to form the moldable, uncured composite. A moldable, uncured nonwoven composite and a molded, cured nonwoven composite are also disclosed.

A process for forming a moldable, uncured nonwoven composite containing forming a structural nonwoven layer, at least partially impregnating the structural nonwoven layer with an uncured, water-based thermosetting resin having a cure temperature of at least about 160° C., and at least partially drying the uncured, wet nonwoven composite such that the temperature at the inner plane is less than about 130° C. forming an moldable, uncured composite. The structural nonwoven layer contains a plurality of bi-component binder fibers and a plurality of reinforcing fibers, the bi-component fibers containing a core and a sheath. The core contains a polymer having a melting temperature of at least about 180° C. and the sheath contains a polymer having a melting temperature less than about 180 ° C. A process for forming a molded, cured composite containing forming a structural nonwoven layer and a molded cured nonwoven composite are also disclosed.

A process for forming a moldable, uncured nonwoven composite containing forming a structural nonwoven layer, at least partially impregnating the structural nonwoven layer with an uncured, water-based thermosetting resin having a cure temperature of at least about 160° C., and at least partially drying the uncured, wet nonwoven composite. The structural nonwoven layer contains a plurality of binder fibers and a plurality of reinforcing fibers which are cellulosic fibers. Heat and pressure are applied to the moldable, uncured composite to a temperature of at least about 160° C. at least partially melting the binder fibers, curing the water-based thermosetting resin, and bonding at least a portion of the reinforcing fibers to other reinforcing fibers forming the molded, cured composite. The reinforcing fibers react with and form covalent bonds with the thermosetting resin.

Packaging insulation for insertion into a packaging container, which includes an air laid natural fibrous batt comprised primarily of natural fibers, having foldable paper sheet material adhered to both sides of the batt. The resulting method and product provides packaging insulation which can be shipped flat and compressed, which expands when unpacked and which can be readily folded to match the interior configuration of a shipping container, such as a cardboard box.

A reinforced sandwich panel, including two skin panels; a foam core disposed between the two skin panels; and an expandable framework disposed within the foam core.

An appliance is provided. The appliance includes a cellulose-based insulator. The cellulose-based insulator has a basis weight of 80 g/m.sup.2 to 500 g/m.sup.2 and an airflow resistance of 500 mks rayls to 2,500 mks rayls. The cellulose-based insulator attenuates low frequency noise and exhibits excellent fire resistance.
