Aspects herein are directed to a moisture wicking and perspiration concealing knit spacer textile and garments formed therefrom that includes a first knit layer formed from yarns that have been treated with a durable water repellant (DWR) finish prior to being formed into the first knit layer and a second knit layer formed from yarns that have been treated with a wicking finish prior to being formed into the second knit layer. The first knit layer and the second knit layer are interconnected by tie yarns. When the textile is formed into the garment, the second knit layer is configured to be positioned adjacent to a skin surface of a wearer and the first knit layer forms an outer-facing surface of the garment.

Provided is a waterproof gas-permeable membrane (1) having higher levels of both gas permeability and waterproofness than conventional ones. The waterproof gas-permeable membrane (1) includes: a non-porous resin film (2) having through holes (21a to 21g) formed to extend through the thickness of the resin film (2); and a liquid-repellent layer (3) formed on a principal surface of the resin film (2) and having openings (31) positioned in register with the through holes (21a to 21g). The through holes (21a to 21g) extend straight and have a diameter of 15 μm or less. The through holes (21a to 21g) are distributed at a hole density of 1×10.sup.3 holes/cm.sup.2 or more and 1×10.sup.9 holes/cm.sup.2 or less in the resin film (2). The through holes (21a to 21g) extend in oblique directions with respect to a direction perpendicular to the principal surface of the resin film (2). The through holes (21a to 21g) that extend in different oblique directions are present together.

The present invention relates to a multi-layer polypropylene film comprising: A base layer of polypropylene (2); Optionally, a tie layer (3) comprising a blend of polypropylene and an sacrificial engineering thermoplastic; A top layer (1) comprising film having a structured surface with water contact angles (WCA) superior to 104.5°, preferentially superior to 110°, more preferentially uperior to 120°, more preferentially superior to 130°; Wherein the top layer comprises a blend 20 to 40 wt % of polypropylene and 60 to 80 wt % of said engineering thermoplastic and in which the engineering thermoplastic has been selectively etched in order to create the said structured surface.

The present invention is directed to an acoustic ceiling panel having a first major exposed surface opposite a second major exposed surface, the acoustic ceiling panel comprising: a first layer having an upper surface opposite a lower surface, the first layer comprising: a first body comprising a first major surface opposite a second major surface and a side surface extending between the first and second major surfaces, the first body being air-permeable; and a first attenuation coating applied to the first body; a second layer having an upper surface opposite a lower surface, the second layer comprising: a second body comprising a first major surface opposite a second major surface and a side surface extending between the first and second major surfaces, the second body being air-permeable; and a second attenuation coating applied to the second body; and an adhesive present between the first and second layers.

A protective garment, gussets for protective garments, and individual gusset layers, being a moisture wicking layer, a core moisture absorbing layer and a moisture impermeable layer, and combinations thereof. The moisture wicking layer including a double knit fabric wherein a technical face of the fabric forms an eyelet mesh utilising both hydrophilic and hydrophobic yarns and a technical back of the fabric forms an interlock utilising only hydrophilic yarns. The moisture absorbing layer including a sinker terry fabric knit comprising sinker loops with plush loops made form synthetic fibres treated with a hydrolysing enzyme that splits the fibres into fibrils. The moisture impermeable layer including a base fabric knit laminated with a polyurethane sheet.

Described herein are physically crosslinked, closed cell continuous multilayer foam structures that includes a foam layer comprising polypropylene, polyethylene, or a combination of polypropylene and polyethylene and a polyamide cap layer. The multilayer foam structure can be obtained by coextruding a multilayer structure comprising at least one foam composition layer and at least one cap composition layer, irradiating the coextruded structure with ionizing radiation, and continuously foaming the irradiated structure.

There is provided a laminate membrane for an implant, comprising: an inner layer having an inner layer thickness; a first covering layer disposed on one side of the inner layer, the first covering layer having a first covering layer thickness; and a second covering layer disposed on another side of the inner layer, the second covering layer having a second covering layer thickness.

Disclosed are a piece of three-layer core-spun webbing, and a seat comprising the webbing. The webbing comprises a woven layer and an inner core, wherein the inner core comprises a filling layer and an interlayer, the interlayer is filled with the filling layer, and an outer surface of the interlayer is in contact with an inner surface of the woven layer. The webbing of the invention has a high tensile strength and a good elasticity, can quickly dry, and is round.

The area of a spacer that is to be provided between the adjacent substrates in a laminate including a plurality of substrates to keep the adjacent substrates apart from each other is smaller than those of the stacked substrates. When pressure is released to bring the laminate obtained by providing the spacers between the substrates from a pressed state in which 0.60 MPa of pressure is applied to the laminate in the stacking direction into a non-pressed state, an amount of change ΔW in thickness per spacer that is calculated from a change in the thickness of the laminate due to the release of pressure is 30 μm or less.

Described herein is an stain and sag resistant acoustic building panel comprising a porous body formed from building material and latex binder, wherein the building material may include fibers and filler and at one of the building materials has been pre-treated with a charge-modifying component, thereby enhancing the sag-resistance of the building panel.
