The printable layer may comprise a polyester, double-knit jersey fabric layer. In embodiments, the water-resistant and stretchable layer further comprises an adhesive layer, the adhesive layer being adhered to the nylon fabric layer. In embodiments, the water-resistant and stretchable layer further comprises a peel-away layer being adhered to the adhesive layer.

A wearable article such as an article of athletic gear (e.g., a skate, an article of protective athletic equipment such as a helmet, etc.) wearable by a user and comprising an expandable user-engaging structure that is configured to be expanded (e.g., by heat or another stimulus) after manufacturing of the wearable article to conform it to the user or otherwise improve a fit of the wearable article on the user.

A personal hygiene device that includes a front side and a base. The front side has a cleaning surface comprising a mesh material configured for exfoliating a user's skin. The base is configured for coupling the device to surface, such as a bathroom surface. In aspects, the bathroom surface is a side of a bathtub or shower wall.

A functional belt has a foam layer and at least one further functional layer. The foam layer and the further functional layer are joined to one another by laser transmission welding, in particular by NIR laser transmission welding. A method for producing a functional belt includes the following method steps: providing a compressible foam layer; providing a further functional layer bringing together the foam layer and the further functional layer and joining the compressible foam layer to the further functional layer by laser transmission welding, in particular by means of NIR laser transmission welding. A technical textile, in particular a fabric for use in a machine for the production or processing of a fibrous material web, preferably press felt of a paper machine, a sealing band or a textile-reinforced insulation material, includes, or is made of, such a functional belt.

The present invention relates to multi-layer fiber products and a method of manufacturing these kinds of products. The present product comprises a first layer consists mainly of natural fibers and a second, heat-sealing layer located on top of the first layer. The heat-sealing layer consists mainly of synthetic thermoplastic fibers or particles. According to the present method, the heat-sealing layer is brought onto the first layer already during the web forming process, the first and the second layers being formed and joined together in a foam forming process. With the present invention, it is possible to decrease the amount of plastic materials in packaging materials having heat-sealing properties.

Provided is a double-faced PSA sheet having excellent detergent resistance. The PSA sheet according to this invention comprises a PSA layer and is adhesive on both faces. The PSA sheet shows a push-peel strength of 30 N/cm.sup.2 or greater after a detergent immersion test involving immersion in a standard detergent at 40° C. for 24 hours. It also has an adhesive strength retention rate of 50% or higher, determined as the ratio of push-peel strength P2 after the detergent immersion test to push-peel strength P1 before the detergent immersion test.

A separator containing a substrate and a release layer formed on at least one side of the substrate wherein the separator shows a strain of not more than 7% when a load of 5N/20 mm is applied for one minute in the pulling direction, and when the substrate is cut in half in the thickness direction to divide the separator into two, an apparent elastic modulus in the pulling direction of one of the divided separators is larger than an apparent elastic modulus in the pulling direction of the other divided separator.

A piezoelectric speaker-forming laminate (10) includes: a piezoelectric film (35); a pressure-sensitive adhesive face (17); an interposed layer (40) being a porous body layer and/or a resin layer disposed between the piezoelectric film (35) and the pressure-sensitive adhesive face (17); and a release layer (20) joined to the pressure-sensitive adhesive face (17). The pressure-sensitive adhesive face (17) is disposed in such a manner that at least a portion of the piezoelectric film (35) overlaps the pressure-sensitive adhesive face (17) when the piezoelectric film (35) is viewed in plan. The piezoelectric film (35) and the interposed layer (40) are allowed to be fixed to a support (80) as a piezoelectric speaker or a portion of a piezoelectric speaker by sticking the pressure-sensitive adhesive face (17) from which the release layer (20) has been removed to the support (80).

The present disclosure provides descriptions of configurations for noise reducing and cooling enclosures and enclosure material. The noise reducing and cooling enclosures seal and passively acoustically quiet acoustic energy generated by one or more noise emitting devices within the enclosure, and dissipate heat generated by the devices through conduction by use of composite enclosure materials.
