Aspects herein are directed to a composite textile having a substrate layer (e.g., knit, woven, nonwoven, etc.) and a film layer that is secured or bonded to the substrate layer. A plurality of slits extend through both the substrate layer and the film layer. The film layer is formed of a material that dimensionally transforms when exposed to an external stimulus such as moisture. When exposed to moisture the film layer swells, which causes flaps formed by the plurality of slits to extend in a z-direction away from the film layer. The opening of the flaps creates through-passages that extend through the thickness of the composite structure.

Aspects herein are directed to a woven, breathable textile. The textile comprises a first woven zone and a second woven zone, where the first and second woven zones are integrally woven such that a particular warp yarn extends through both the first woven zone and the second woven zone of the textile. The first woven zone comprises a first woven layer and a second woven layer with a space or void formed between the first and second woven layers. The second woven zone comprises a single woven layer comprising a plurality of apertures formed through the weaving process, where each aperture is located at the center of a repeating pattern of interlacings.

This invention provides a respirator for detecting viruses which cause respiratory tract infection. The respirator comprises an outer layer, an inner layer, a rapid screening reagent between the outer layer and the inner layer, and a water-resist membrane between the rapid screening reagent and the inner layer. A sample pad of the rapid screening reagent is located on a region close to the nostrils, such that air from the nostrils will arrive the sample pad. Viruses inside the air with vapors or moistures will flow inside the rapid screening reagent through a conjugate pad, a nitrocellulose membrane, and an absorption pad. At least one test line will indicate a corresponding virus.

A protective device for maintaining body temperature in a living being is provided. The inventive protective device comprises a first sheet member having a left portion and a right portion. The first sheet member has a left edge and a right edge. A first channel member defines structure defining a first channel. The first channel member defines structure which is secured to and overlies a first portion of the left portion of the first sheet member and overlies a first portion of the right portion of the first sheet member. A second channel defining structure defines a second channel, the second channel defining structure secured to and overlying a second portion of the left portion of the first sheet member and overlying a second portion of the right portion of the first sheet member. Each of the channels have a first side and an opposite side opposite the first side. A variable length member is disposed on and extends along the length of each of the channels. There is a connection structure positioned proximate the left edge; and a mating connection structure positioned proximate the right edge.

A breathable barrier fabric that is heat sealable and minimizes lint generation without impacting the fabric's overall breathability, comfort and barrier protection, and that can be used to manufacture Helmke Category II or better cleanroom garments suitable for use in ISO Class 3 cleanroom environments and other hygienic applications. The breathable barrier fabric has a composite laminate structure including an inner monolithic film layer made from a breathable polymer bonded to first and second outer spunbond layers comprising thermoplastic bicomponent fibers each having an outer glazed surface where the thermoplastic bicomponent fibers are at least partially flattened.

The apparel is constructed from various combinations of layers of materials with moisture transfer properties. A first liner of moisture transfer fabrics abuts a second layer of structural material such as open-cell foam. The second layer can abut a breathable membrane and/or an insulating material. Finally, carefully selected outer fabric completes the combination to provide apparel with improved performance characteristics. The outer fabrics are treated in various ways to enhance performance.
