The invention provides a knitted functional fabric for wicking moisture away from the body of a user. The fabric comprises a technical face formed from a yarn; a technical back formed from a yarn; and a spacer formed from a yarn that connects the technical face to the technical back. The technical face and the technical back comprise a hydrophilic yarn.

A synthetic radiator fabric with permanent mechanical wicking defines an inner surface and has a raised knit body defining an opposite outer surface. The fabric includes hydrophilic and hydrophobic fiber-containing yarns. At the inner surface, the hydrophilic fiber-containing yarns collect liquid sweat from a wearer's skin surface and maintain the collected sweat at the inner surface, generally in the vicinity of and/or in contact with the wearer's skin, for encouraging evaporation of sweat and providing evaporative cooling. The raised knit body extends from the inner surface toward, and defines, the opposite outer surface. The hydrophobic fiber-containing yarns are arranged in a radiator-like construction forming egg-crate or honey-comb like cells or pores, defined by the knit body and open to the inner surface. At the outer fabric surface, the hydrophobic fibers receive excess sweat from the wearer's body, thereby to encourage rapid evaporation and drying, for improved breathability.

A biodegradable antibacterial knitted fabric, a cross section of the knitted fabric includes a front side of cross section made of wool short fiber yarns, an intermediate connection layer of cross section capable of transferring moisture and a rear side of cross section made of antibacterial filaments; the intermediate connection layer of cross section is made of filament yarns having a special shape capable of being inserted into the front side of cross section and the rear side of cross section so that the front side of cross section is connected with the rear side of cross section. The biodegradable antibacterial knitted fabric proposed by the present application has a long time significant antibacterial effect by adopting a cross section structure with three layers and antibacterial material, and does not contain any antimicrobials and metal ions, and has the advantages of low cost, easy manufacturing and long lasting antibacterial effect.

The present invention relates to textile articles and clothing such as outdoor garments, indoor garments, and commercial protective wear exposed to contact mixtures of water and oil, swimwear and winter wear exposed to mixtures of water and air. At least part of these textile articles possess a surface provided with at least one of 1) a high surface area, 2) hierarchical pattern, 3) contact angles such that hydrophilic portion of a contact mixture possesses a high contact angle and the hydrophobic portion of a contact mixture possesses a low contact angle, and 4) hysteresis angle greater than 5 degrees. Hydrophobic/Hydrophilic contact mixtures of the present invention can be surfaces where water and or ice are present in combination with oil and or air. The textile articles of the present invention resist slippage on surfaces possessing hydrophobic/hydrophilic contact mixtures.

Provided herein are a controllable liquid transport material, a controllable liquid transport system and a method for preparing a controllable liquid transport material, where a first region of the controllable liquid transport material is treated to be hydrophobic, while a plurality of second regions partially contacted or completely separated with different shapes are treated to have a gradient or varied wettabilities and/or pore sizes for passively controllable liquid transport, and/or integrated with a smart material for actively controllable liquid transport driven by an external force, allowing efficiently and controllably directional transport of a liquid e.g., sweat. The controllable liquid transport system comprises a controllable liquid transport material used as a liquid transport layer and a breathable, waterproof protective layer.

Aspects herein relate to a knit textile or garment that comprises at least a first and second portion. The first portion comprises a first percentage by weight of a first yarn and a second yarn. The second portion comprises a second percentage by weight of the first yarn and the second yarn. The two portions are integrally knitted from each other. The second portions provide a high level of air permeability, while the first portions provide moisture wicking and may be used as modesty portions in garments.

A multi-ply fabric is disclosed. The fabric has a top yarn arranged to face an atmosphere and a bottom yarn connected to the top yarn, arranged to contact a surface of a user's body. The bottom yarn has a surface area to volume ratio (SA:V) that is greater than the SA:V of the top yarn. In some embodiments, the bottom yarn has a SA:V that is about 25% to about 50% greater than the SA:V of the top yarn.

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.

Nonwoven materials having at least one layer comprising high core bicomponent fibers are provided. The nonwoven materials can have multiple layers and are suitable for use in a variety of applications, including in absorbent products. Such nonwoven materials can be patterned to create a three-dimensional topography including indentations formed of valleys and ridges. The nonwoven materials can have improved resiliency and strength and can retain their structure under wetted conditions and after tension and compression. The nonwoven materials can further facilitate the transfer of the liquid through the nonwoven material for improved liquid distribution and can also have improved liquid retention properties.

Fabric treatment compositions that include certain polymer systems, such as systems that include a first polymer that is a soil release polymer and a second polymer that is a graft copolymer (e.g., a PEG/vinyl acetate polymer), an alkoxylated polyalkyleneimine polymer, or a mixture thereof.
