The present invention provides a fabric comprising or consisting of: a first yarn comprising a fiber blend of modal and polyester; a second yarn comprising spandex; and a third yarn comprising polyester. The polyester in the fiber blend may have a cross-section such as X-shape, M-shape, I-shape, honeycomb-shape, Y-shape, U-shape or O-shape that creates a plurality of spaces along the length of the first yarn that facilitate a capillary action. The modal in the fiber blend may have a cross-section that is substantially rectangular.

Disclosed herein is a knitted multi-layer fabric construction that provides the ability to cool skin to below a current temperature whether wetted or dry. The knit uses four separate yarns which collectively work together to produce enhanced cooling. Knits can include warp knit, seamless, hosiery, flat bed, spacer, and double knits. Various finishing methods may also be employed to enhance the cooling power of the fabric.

In a stretch yarn (1) comprising a stretchable core (2) covered by an inelastic fibers sheath (3) the stretchable core (2) comprises first and second fibers (4, 5) that have elastic properties, the first fiber (4) is an elastomer and the second fiber (5) is a polyester based (co)polymer, the amount of the second fiber being in the range of 60-90% (w/w) of the total weight of the fibers of the stretchable core (2); the first and second fibers are connected together at least at a plurality of points (P).

A method of making a yarn is disclosed. A plurality of fibers is obtained by: preparing a slurry of polymer mixed with water insoluble nanoparticles of electrolytic copper, and extruding the slurry through a spinneret that includes a plurality of holes which impart a generally X-shaped cross-section to the plurality of fibers. The plurality of fibers are spun together to form the yarn.

In one aspect, the disclosure relates to composite yarns having a structure comprising a core component and sheath layer, wherein each of the core component and the sheath layer independently comprise a polymer and a disclosed cooling composition. In various further aspects, the present disclosure pertains to double covered yarns comprising an elastic core comprising an elastic core; a first yarn in contact with the elastic core, and wherein the first yarn comprises a disclosed yarn comprising a core component and a sheath layer; and a second yarn in contact with the first yarn, and wherein the second yarn comprises a yarn comprising a cellulosic fiber. In still further aspects, the present disclosure pertains to a fabric, such as a denim fabric. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.

Described herein are spun yarns, core spun yarns, and fabrics such as denim fabrics made thereof that contain recycled cotton fibers and recycled para-aramid fibers. The combination of fibers in the yarns and fabrics provide desirable properties such as increased tear strength, breaking strength, and abrasion resistance compared to yarns and fabrics made of 100 wt % cotton.

The present disclosure provides a fabric including at least one interlaced thermoplastic yarn. The fabric includes a first region and a second region. At least a portion of the thermoplastic yarn in the first region is fused together, and the thermoplastic yarn in the second region is not fused.

A method of making a yarn is disclosed.

In a stretch yarn (1) comprising a stretchable core (2) covered by an inelastic fibers sheath (3) the stretchable core (2) comprises first and second fibers (4, 5) that have elastic properties, the first fiber (4) is an elastomer and the second fiber (5) is a polyester based (co)polymer, the amount of the second fiber being in the range of 60-90% (w/w) of the total weight of the fibers of the stretchable core (2); the first and second fibers are connected together at least at a plurality of points (P).

An elastic woven fabric comprising weft and warp yarns, the weft yarns including elastic composite yarns each of which comprises an elastic core yarn and a sheath yarn covering the elastic core yarn, and the warp yarns including chemical fiber yarns and/or natural fiber yarns. Each of the elastic composite yarns is in a form of a singly-covered yarn in which the elastic core yarn is covered by a single layer of the sheath yarn helicoidally wound around a periphery of the elastic core yarn, a number of turns of the sheath yarn per 1 meter of the elastic core yarn being in a range of 1,000 to 2,500 T/m. A stretching magnification ratio of each of the elastic composite yarns, in the elastic woven fabric in a weaving process, is retained equal to or less than 1.30 folds based on the elastic composite yarn before weaving.
