Some embodiments of the present disclosure relate to roofing systems. In some embodiments, the roofing system includes a deck, a roofing material, and an underlayment configured to be positioned between the roofing material and the deck. In some embodiments, the underlayment comprises a foil layer and an adhesive layer that is attached to the foil layer and configured to be attached to the deck. Methods of manufacturing roofing systems are also disclosed.

Laminated light-blocking decorative articles are prepared by applying an aqueous foamed opacifying composition to a non-woven fabric, drying, laminating a decorative fabric to the resulting dry foamed opacifying layer, and densifying that layer to have a thickness that is at least 20% less than before densifying. This operation can be carried out so that non-woven fabric, decorative fabric, and aqueous foamed opacifying composition are supplied in a single-pass, in-line operation to make any desired quantity of a laminated light-blocking decorative article. The applied aqueous foamed opacifying composition has 35%-70% solids and a foam density of 0.1-0.5 g/cm.sup.3. It is composed of (a) porous particles, (b) a binder material, (c) two or more additives comprising at least one foaming surfactant and at least one foam stabilizer, (d) an aqueous medium, and (e) at least 0.0001 weight % of an opacifying colorant that absorbs electromagnetic radiation having a wavelength of 380-800 nm.

The present invention relates to the manufacturing equipment for web materials comprising fibers and particulate material, to a process of operating such an equipment and to particular materials resulting therefrom. Coaxially meltblown fibres are combined with a stream of particulate or short fiber material and the resulting commingled mixture is deposited onto a collector. The meltblown fibers are formed by nozzles which are divided into two or more sub-arrays configured to produce two or more different types of fiber, having e.g. different diameters and/or polymer composition.

An installation and a method for selectively producing a single-ply or alternatively a multi-ply nonwoven includes an inclined wire former configured to deposit a sheet of wet-laid fibre material on a first circulating belt, a further belt configured to receive the sheet of wet-laid fibre material from the first circulating belt, a roller card arranged downstream in the material transport direction and configured to introduce a roller card web into the installation, a hydroentanglement arranged downstream in the material transport direction and including at least one water beam configured to entangle, bond and/or structure a single sheet of fibres or a plurality of sheets of fibres, and a dryer arranged downstream in the material transport direction

A composite material having a molten polymer barrier effect with flame-retardant properties includes a first layer of non-woven fabric having 40% or more by weight of oxidized polyacrylonitrile fibers to confer flame-retardant properties. The first layer has a basis weight of 200-600 g/m2 and a thickness of 1.6-5 mm. A barrier layer overlaps the first layer and counteracts passage of molten polymer. The first layers oxidized polyacrylonitrile fibers have a count of 1.5-5 dtex and the other first layer synthetic fibers have a count of 0.8-5 dtex. The barrier layer includes a second layer of non-woven fabric of hydro-entangled synthetic and/or artificial fibers. The barrier layer has a basis weight of 70-150 g/m2; a thickness of 0.4-1.5 mm; and a permeability of 200 L/m2s-2000 L/m2s under a pressure drop of 2 mbar. The composite material has a thickness of 2-6.5 mm, and a basis weight of 270-750 g/m2.

A multi-layer protection element for thermal insulation of a battery, a battery with such a protection element and the use of the protection element to filter gases escaping in case of fire and to prevent the escape of flames and/or sparks are proposed. The highly gas-permeable protection element comprises a carrier layer of a fabric and a compressible fibre layer in the form of a sewn non-woven fabric. The protection element is arranged between at least one battery cell and a housing wall of the battery and covers an outlet of the housing wall on the inside. This enables good pressure compensation in the event of fire and/or a short circuit, wherein escaping gases are filtered in particular through the fibre layer and the escape of flames or sparks through the outlet is prevented.

Provided is a composite sheet material having a first layer and an airlaid nonwoven layer overlying the first layer wherein the airlaid nonwoven layer includes a blend of bamboo derived staple fibers and non-cellulose staple fibers, and in which the airlaid nonwoven layer includes a first surface disposed towards, and thermally bonded, to a surface of the first layer, and a second surface defining an outer surface of the composite sheet material.

Disclosed is a fully enclosing engine or unit capsule of a motor vehicle with an air cushion foil, whereby the acoustic component properties can be significantly influenced, tuned.

The present disclosure provides a method of making an additive manufactured article. The method includes: a) attaching a multilayer structure (300, 500) to a build platform (210); b) selectively curing a photocurable composition (219) that is in contact with a porous layer (330, 530) of the multilayer structure, thereby forming an object attached to the porous layer; and c) separating the object from the build platform. The multilayer structure includes an adhesive layer (310, 510), an impermeable layer (320, 520) attached to the adhesive layer, and a porous layer (330, 530) attached to the impermeable layer. The adhesive layer of the multilayer structure is attached to the build platform. The present disclosure also provides an object made by the method, and the multilayer article used in the method. Use of the multilayer article assists in improving adhesion between the build platform and the object.
