A dehumidifying element includes a plurality of sheets that have moisture adsorption and desorption properties and that are stacked on top of each another. At least some of the sheets each have an irregular shape. The sheets each contain a hygroscopic agent having properties of a re-moistening-type glue that exhibits adherence when adsorbing moisture and that solidifies when being dried. The sheets are bonded to each other by the hygroscopic agent.

To provide a flexible conductive base member and a multilayer conductive base member including the same, having no problem of failing to function as a contact and causing a variation in height between contacts.

There are a covered region 10 covered with a noble metal and a non-covered region 20 not circumferentially covered with a noble metal on a surface of a reticulated fibrous body 50. The covered region 10 is located at an intersection 7 of fibers 5 of the reticulated fibrous body 50, and the intersections 7 are connected to each other. The non-covered region 20 is located between the intersections 7 of the fibers 5 of the reticulated fibrous body 50.

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.

A roofing underlayment includes a hydrophobic nonwoven core layer that provides enhanced resistance to water infiltration. In addition to the hydrophobic nonwoven core layer, the roofing underlayment includes a coating layer adhered to a surface of the hydrophobic nonwoven core layer, and an exterior surface layer adhered to the coating layer. A roofing system that includes the roofing underlayment is also provided.

A composite material for dissipating the kinetic energy of an impacting object includes a strike face oriented to receive the impacting object and a protected face oriented to be proximate a user or a protected item. A first portion includes at least a first woven fabric layer and at least a Non-Newtonian Fluid (NNF) sheet. The first portion is disposed adjacent the strike face. A second portion includes at least a second woven fiber layer, and the second portion is disposed adjacent the protected face.

The present disclosure is related to a composite sandwich panel having a first layer including mica paper, a folded core or honeycomb structure including mica paper and a second layer including mica paper. The first and second layers are glued onto the foldcore using mineral adhesive made of one or more alkali metal silicate(s).

A wound dressing material comprises first and second wound-contact scrims, and an antimicrobial layer disposed therebetween. The wound-contact scrims comprise water-sensitive fibers comprising a copolymer comprising divalent hydroxyethylene monomer units and divalent dihydroxybutylene monomer units. The wound dressing material may be contacted with an exposed surface of a wound. A method of making the wound dressing material is also disclosed.

A composite nonwoven mat and a method of making a composite nonwoven mat are provided. The composite nonwoven mat includes a nonwoven base layer having a first surface and a second surface, and a coating layer formed on, penetrating into, and adhered to the first surface of the nonwoven base layer. The coating layer includes a polymer material and a carrier composition. The composite nonwoven mat has an average Gurley porosity of at least 500 seconds.

Proposed is an air purifying filter. The air purifying filter includes a filtering layer (30) configured as a dielectric which collects minute particles, a first electrode layer (50) laminated on a side of the filtering layer (30) and comprising insulated wires (51) to which power is able to be applied, and a second electrode layer (70) laminated on a side of the filtering layer (30) opposite to the side of the first electrode layer and comprising a conductive material such that a polarity opposite to a polarity of the first electrode layer (50) is applied to the second electrode layer or the second electrode layer is grounded.

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.
