Substrates with transparency to infrared body radiation and opacity in the visible light spectrum are provided and systems and methods for creation thereof are provided. The IR radiation transparent substrate is IR radiation transparent and visible light opaque with enough breathability and softness to make it suitable for use in garments for body thermal regulation. Further, the IR radiation transparent substrate is created utilizing nanofiber technology to form specific sized micro pores between the nanofibers.

A multi-layer tubular woven construct is useful as a hose that transports a fluid or a powder or protects linear bodies such as wires, cables and conduits, as a tubular filter, or as a base material of a vascular prosthesis. In particular, a tubular woven construct in a tubular configuration woven by interlacing warp and weft yarns contains at least in part an elastic fiber yarn having a filament fineness of 1.0 dtex or more, the weft yarn containing at least in part a microfiber yarn having a filament fineness of less than 1.0 dtex.

A carbon dioxide blocking system is provided comprising a sheeting material treated with a waterproofing agent such that the carbon dioxide blocking system is fully, or nearly fully, impermeable to liquids and gases. The sheeting material may be a microfiber polyester woven sheeting material and the waterproofing agent may be thermoplastic polyurethane. The sheeting material is treated with the waterproofing agent. The treated material comprises a single layer of fabric. The sheeting material provides a soft upper surface, like a sheet, while the waterproofing agent imparts impermeability to the sheeting material such that the carbon dioxide blocking system may serve as a mattress protector to block liquids and also to block the permeability and retention of carbon dioxide to help prevent carbon dioxide rebreathing.

Provided are a woven fabric having excellent lightweightness and water resistance and a garment using the woven fabric. The woven fabric has an areal weight of 100 g/m.sup.2 or less and a cover factor of 1,800 or more. One of the warp and weft of the woven fabric contains a false-twist crimped yarn, and the other contains a non-crimped yarn.

Infrared-transparent visible-opaque fabrics for wearable personal thermal management.

A multi-layer composite structure is conformable to the contours of the body parts for which protection is required. The composition structure contains a rigid shock-deflecting outer layer, two semi-rigid shock-damping and shock-dissipating middle layers, and a pliable shock-absorbing lower layer. In one embodiment, the structure is designed for impacts associated with contact sports, such as football, hockey and lacrosse. In another embodiment, the structure is designed for military/police applications, in which impacts can be blunt forces, from weapons such as clubs, or penetrative forces, from knives, bullets or shrapnel.

A fire resistant textile material comprising a fire resistant textile material comprising a woven face fabric composed of fibres selected from: meta-aramid, para-aramid, polyamideimide and mixtures thereof; wherein the number of warp face threads, per unit width (cm) is greater than the number of weft threads, per unit length (cm).
