Optionally, the face fibers can comprise a plurality of tufts extending through the backing. The backing can define a plurality of perforations that fully extend through the thickness of the backing and are provided in a pattern to determine an acoustic property of the sound-absorbing article. Within at least a portion of the backing, sequential perforations within the pattern of the plurality of perforations can be spaced center-to-center by between 5 mm and 100 mm.

A layered thermal insulation system generally conformable to three-dimensioned surfaces of heat-producing elements in need of insulation is described. The system comprises: i) an inner high temperature resistant insulation layer; ii) an outer high temperature resistant insulation layer adjacent the inner high temperature resistant insulation layer; and, iii) a first reflection layer and a second reflection layer. Each of said reflection layers is formed of a material selected from a group consisting of metal foils and are provided with a plurality of dimples and/or protrusions. The first reflection layer is adjacent the inner high temperature insulation layer such that, in use, an opposing surface thereof is in close proximity to said surfaces of said element to be insulated. The second reflection layer is adjacent to the outer high temperature insulation layer such that, in use, an opposing surface thereof comprises an exposed surface having a lower temperature than said surfaces of said element.

Described is a composite made from a woven fabric, a non-woven fabric, or a knitted face fabric and a non-woven fabric. The woven fabric, the non-woven fabric, or the knitted face fabric is needle punched such that fibers protrude into the non-woven fabric. The woven fabric, the non-woven fabric, or the knitted face fabric has a first polymer having a first melting point and a second polymer having a second melting point being higher than the first melting point. The nonwoven backing material comprises a third polymer having a third melting point and a fourth polymer having a fourth melting point being higher than the third melting point. The woven fabric, the non-woven fabric, or the knitted face fabric is further bonded to the nonwoven backing material applying heat to at least partially melt or soften the first polymer and the third polymer such that they bond together.

The present invention relates to a patient board suitable for supporting a patient during medical imaging, radiotherapy and/or surgery. The board comprises a composite comprising a natural or naturally-derived fibre and a thermoset matrix.

A cloth mask includes a body, where the body has a piece of copper ion cloth and a piece of zinc oxide antibacterial cloth, the copper ion cloth is woven by a mixture of a first yarn, a second yarn and a copper yarn, the first yarn has a hydrophobicity and a moisture permeability and can form a water-resistant surface, and has a water-repellent effect and is exposed at an inner layer of the copper ion cloth, and the second yarn has a moisture-removing property and can form an antibacterial and moisture-removing surface to be exposed together with the copper yarn on a surface of the copper ion cloth.

A prepreg including an epoxide resin matrix system and fibrous reinforcement, at least partially impregnated by the epoxide resin matrix system, the epoxide resin matrix system having the components: a. a mixture of (i) at least one epoxide-containing resin and (ii) at least one catalyst for curing the at least one epoxide-containing resin; and b. a plurality of solid fillers for providing fire retardant properties to the fibre-reinforced composite material formed after catalytic curing of the at least one epoxide-containing resin, and wherein the fibrous reinforcement is a woven fabric ply of an interwoven mixture of glass fibres and carbon fibres, the woven fabric ply has a weight of from 350 to 550 g/m.sup.2 and is from 40 to 95 wt % glass fibres and from 5 to 60 wt % carbon fibres, each based on the weight of the woven fabric ply, and the proportion by weight of carbon fibres, expressed as C in wt %, in the woven fabric ply is defined by the formula:

[00001]$C\ge \left(-0.0048W+2.0858\right)\times 100\%,$ where W is the weight of the woven fabric ply in g/m.sup.2,
and the proportion by weight of glass fibres, expressed as G wt %, in the woven fabric ply is defined by the formula: G=(100−C) %.

A head garment is made of elastically stretchable fabric configured to fit over and surround the head of a wearer and conform substantially to the shape of the wearer's head. The head garment has an eye opening positioned to allow the wearer to see therethrough, and a protective eye shield completely covering the eye opening. A multi-layer filter portion is configured to cover the wearer's mouth and at least a lower part of the wearer's nose and has three or more filter layers for filtering air during breathing. Additional filter layers may be added to the multi-layer filter portion to enhance or modify the filtering properties. The multi-layer filter portion may be configured as a removable filter pack that can be removed and replaced by other filter packs having different filtering properties.

A multi-piece floor arrangement and assembly forms a floor covering that includes a top, or upper, rug portion and bottom, or lower, mat portion, and pocketed corner areas in each corner of an underside surface of the rug portion into which corresponding corners of the mat portion are insertable. The pocketed corner areas secure the rug portion with the mat portion when both are placed on an underlying surface while enabling a flow of air between the rug portion and the mat portion. The mat portion includes multiple interlocking sections that help to maintain the floor covering in a uniform planar shape and provide an aesthetically-pleasing appearance when placed on an underlying surface. The multi-piece arrangement and assembly does not move relative to that surface, yet does not require either a cumbersome installation or removal process.
