Disclosed herein is a warp knit spacer dual functional fabric construction that provides the ability to absorb sweat on one side and the ability to cool skin to below a current temperature whether wetted or dry on the other side. The knit uses four separate yarns which collectively work together to produce enhanced cooling. Knits can include warp knit spacer and circular knit spacer materials. Various finishing methods may also be employed to enhance the cooling power of the fabric.

A filter medium is provided. A filter medium according to an embodiment of the present invention comprises: a fiber web layer of a three-dimensional network structure including nanofiber; and a hydrophilic coating layer which covers at least a part of the outer surface of the nanofiber. According to this, a flow rate can be remarkably increased due to the improved hydrophilicity of the filter medium. Also, as the improved hydrophilicity is maintained for a long period of time, the lifespan can be remarkably prolonged. Furthermore, since the modification of a porous structure of the filter medium is minimized during the process of hydrophilization so that the initially designed physical properties of the filter medium can be exhibited in its entirety, the filter medium having chemical resistance, excellent water permeability and durability can be variously applied in the water treatment field.

A thermoelectric flexible mat may include a first large surface and a second large surface. The mat may also include a plurality of p-doped elements and a plurality of n-doped elements disposed in an alternating manner with one another and electrically interconnected to a series circuit via a plurality of electrically conductive conductor bridges. The plurality of conductor bridges of the series circuit may be assigned, at least in regions, to the first large surface and the second large surface such that the first large surface defines a hot side and the second large surface defines a cold side. An absorptive absorption structure may connect the hot side and the cold side. The absorption structure may be structured and arranged such that any liquid present on the cold side is absorbable into the absorption structure and transportable to the hot side via the absorption structure.

A multi-effect woven fabric for energy harvesting and heat management includes a combination of a predetermined number of yarns woven to each other in a repeating pattern. The yarns include a first yarn for absorbing, storing, and releasing heat energy through a phase change, a second yarn for converting heat energy from a wearer's skin, the first yarn, and a third yarn into far infrared radiation energy and radiating the far infrared radiation energy to other yarns and to the wearer's skin, the third yarn for absorbing moisture from the wearer's skin and/or ambient environment and generating heat energy through an exothermic process, and a fourth yarn with a hydrophobic property. The multi-effect woven fabric maintains a uniform temperature on the wearer's skin by a combination of heat energy generation, heat energy harvesting, and radiation of heat energy.

A bedding includes: a cushion layer which is formed with a filament three-dimensional bonded member and which is breathable; a breathable water-repellent layer which is provided on the upper side of the cushion layer and which is breathable and water-repellent; and a breathable water-retentive layer which is provided on the upper side of the breathable water-repellent layer and which is water-retentive and is breathable during water retention.

An article including one or more moisture wicking layers and one or more fibrous layers. The fibrous layers may have generally vertically oriented fibers, which may be oriented generally perpendicularly to a surface having or producing moisture. The article may be adapted to remove moisture form the surface having or producing moisture. The article may be breathable. The article may be quick drying. The article may provide cushioning. The article may be a wearable item.

A chinstrap sock to be worn by athletes comprising a tubular body having a skin facing surface for contacting a portion of a wearer's body, and an outer surface opposed to the skin facing surface; an opening in the tubular body for extension therethrough; and a first welt and a second welt affixed to opposite ends of the tubular body in surrounding relation to the opening, the first welt and the second welt each comprising a circularly-knitted fabric integral with the tubular body and extending therefrom to; the tubular body portion being a knitted construction comprising: a skin-facing surface comprising a metal-, metal oxide-, and/or metal salt-containing yarn portion.

Devices for radiative cooling and optical waveguiding are provided, wherein the devices comprise a fabric including one or more fibers extending for a length in a longitudinal direction and a plurality of void structures positioned within each of the one or more fibers and extended over the length of each of the one or more fibers. Each of the plurality of void structures is configured to scatter at least a portion of an electromagnetic radiation received thereon to thereby radiatively cool the object.

The present invention provides a substrate having a unidirectional water transport property, the substrate comprised of a fluid permeable structure and including: an inner side surface; and an outer side surface having a higher absorbent capacity than the inner side surface, wherein the inner side surface has a hydrophobic surface layer extending continuously over at least one section thereof, the hydrophobic surface layer having a predetermined thickness which, in use, produces a substantial hydrophobic property to contacting water, whilst allowing for water contacting the inner side surface of the substrate to wick through the hydrophobic surface layer into the substrate; and wherein the substrate is respectively comprised of hydrophobic channels and hydrophilic channels which respectively extend between the inner side surface and the outer side surface.
