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.

An underlay cushioning sheet that is arranged on the surface of a foundation and that has a waterproof coating film formed thereon. The underlay cushioning sheet includes a cushioning layer having an overlay surface and a curing acceleration layer having a coating film formation surface on the opposite side from the overlay surface. A waterproof coating film including a polyurethane resin is formed on the coating film formation surface of the curing acceleration layer by applying a one pack-type liquid waterproofing material. The curing acceleration layer includes a reactive material capable of reacting with the liquid waterproofing material. The reactive material either (1) includes a functional group capable of reacting with an isocyanate included in the liquid waterproofing material or (2) reacts with a latent curing agent included in the liquid waterproofing material and generates a functional group capable of reacting with the components of the liquid waterproofing material.

Provided are composite particles in which reinforcing fibers adhere to the surface of thermoplastic resin expanded beads via a thermosetting resin being in an uncured state, a cured product of the composite particles, an in-mold molded article of the composite particles, a laminate of the composite particles and a reinforcing fiber sheet material, a composite of the composite particles, and a method for producing composite particles.

Provided is a resin material showing a high thermal conductivity and having high heat resistance while having a low dielectric constant and a low dielectric loss tangent. The material is a polyfunctional vinyl resin, which is represented by the following general formula (1):

##STR00001##

where R.sup.1s each independently represent a hydrocarbon group having 1 to 8 carbon atoms, R.sup.2s each independently represent a hydrogen atom or a dicyclopentenyl group, and at least one thereof represents a dicyclopentenyl group, Xs each independently represent a hydrogen atom or a vinyl group-containing aromatic group represented by the formula (1a), and at least one thereof represents a vinyl group-containing aromatic group, “n” represents a number of repetitions, and the average thereof is a number of from 1 to 5, and Ar represents an aromatic ring.

Precursors and methods for manufacturing perforated composite parts are disclosed. An exemplary precursor (19) comprises structural fibres (24,28) embedded in a cured matrix material (24,26) and interposed between two removable plies (20). The precursor may also comprise a sacrificial fibre (28) extending through the removable plies (20), the matrix material (24,26) and between the structural fibres (24,28). An exemplary method comprises removing the removable plies (20) from the precursor (19) and removing the sacrificial fibre (28) from the precursor after removing the removable plies to form a through hole in the precursor (19) at a location of the sacrificial fibre (28).

The waterproof/breathable moisture transfer liner for a running and hiking shoe includes an inner liner selected from technically advanced fabrics which are carefully selected. A series of layers are provided outside the inner liner including foam material layers, breathable membranes, a supportive mesh or a moldable foam, and an outer shell fabric. The applicability of the liner to alpine, snowboard boots, cross country, hiking boots, protective gear and helmets, along with appropriate variations for each application.

A method of forming a retaining device with hooks, wherein: a molding strip is provided that presents an inside face and an outside face, and that has a plurality of cavities, each cavity defining a stem extending from the outside face towards the inside face and including an end forming a head that extends from the stem towards the inside face of the molding strip; the molding strip is positioned on rotary drive means, the inside face of the molding strip being arranged to bear against the drive means; and molding material is dispensed against the outside face of the molding strip.

A textile composite material for lamination includes: a total material thickness which is smaller than 7 mm, with at least one nonwoven fabric component and with at least one foam material component which is connected to the nonwoven fabric component, the nonwoven fabric component comprises at least one binder fiber having a melting temperature that is greater than 150° C., the nonwoven fabric component comprises at least one functional fiber having a linear mass density value smaller than or equal to 50 dtex, and the functional fiber is embodied as a hollow fiber.

An insulated spa cover (10) contains a thermal insulating core (30), a top cover (150) with an average permeance of at least 57.2 nanograms/Pascal*seconds*square meters, and a hydrostatic head test value of at least 5,000 Pascals, a vapor barrier (130) and optionally a bottom sheet (140) apart from the vapor barrier. Venting pathways are defined around the thermally insulating core to facilitate escape of water vapor.

Filter media, such as electret-containing filtration media for filtering gas streams (e.g., air), are described herein. In some embodiments, the filter media may be designed to have desirable properties such as stable filtration efficiency over the lifetime of the filter media, increased normalized gamma, relatively low pressure drop (i.e. resistance), and/or relatively low basis weight. In certain embodiments, the filter media may be a composite of two or more types of fiber layers where each layer may be designed to enhance its function without substantially negatively impacting the performance of another layer of the media. For example, one layer of the media may be designed to have a relatively low basis weight and/or a relatively high air permeability, and another layer of the media may be designed to have stable filtration efficiency and/or a relatively high efficiency throughout the filter media's lifetime. The filter media described herein may be particularly well-suited for applications that involve filtering gas streams (e.g., face masks, cabin air filtration, vacuum filtration, room filtration, furnace filtration, respirator equipment, residential or industrial HVAC filtration, high-efficiency particulate arrestance (HEPA) filters, ultra-low particular air (ULPA) filters, medical equipment), though the media may also be used in other applications.
