A woven fabric formed of fabric fibers or threads coated with a hydrogel, wherein said hydrogel is not crosslinked or is partially crosslinked to the fabric fibers or thread, wherein the hydrogel has a number of excess reactive molecules that are available for a reaction with one or more molecules solvated in an aqueous solution, and wherein the reactive molecules of the hydrogel can reversibly bond with the molecules solvated in an aqueous solution, such that the reactive molecules of the hydrogel attract the molecules solvated in aqueous solution when the hydrogel coated fabric substrate is exposed to an aqueous solution.

A manufacturing method of a thermoelectric conversion device having a textile structure. The thermoelectric conversion device having a textile structure uses one or multiple types of thermoelectric yarns as thermocouples of a thermoelectric generator structure, and uses elastic insulating yarns as a main carrier portion of a textile article. The invention utilizes the characteristic of a textile article of having woven and overlapping warp and weft yarns, and the thermoelectric yarns are woven into a thermoelectric generator textile article by using a conventional weaving technique. The thermoelectric transfer performance and the performance of the main carrier thereof are adjusted by varying an interweaving structure of the textile article, placement positions of the thermoelectric yarns, and the length of the thermocouples thereof. The present invention is widely and flexibly applicable in the fields of sports and health, medical smart apparel, smart homes, wearable touch screens, electronics, even automobiles, architectures, and the like.

An article of apparel is disclosed that includes zones with a textile having a structure than changes or is otherwise modified by a physical stimulus, such as the presence of water or a temperature change, to modify a property of the textile. The zones may be along a center back area and/or side areas of the apparel, and the textile may increase in air permeability when exposed to water. In some embodiments, slits are formed in the textile.

The present invention provides a method for successively introducing water soluble fibers into finish fibers (e.g. cotton) to produce a hollow and ultra soft structure, by introducing water soluble slivers into the center of a multi-hole feeder with multiple cotton fiber slivers arranged around the water soluble fiber in a pre-drawing process via a multi-hole sliver feeder. A plurality of these fibers can be drawn together to produces a fiber having multiple water soluble fibers. A cloth, e.g., towel, can be made using the method.

The invention provides an antimicrobial fiber which exhibits excellent antimicrobial properties even without the addition of antimicrobial agents and can remain antimicrobial even after repeated washing. The antimicrobial fiber comprises a fiber having on a surface thereof a polyacetal copolymer (X) containing oxyalkylene groups, the molar amount of oxyalkylene groups in the polyacetal copolymer (X) being 0.2 to 5 mol % relative to the total of the molar amount of oxymethylene groups and the molar amount of oxyalkylene groups.

In an example, a system for forming a dust-mitigating fabric includes a warp-strand-delivery unit including warp strands. The warp strands include insulative-warp strands and conductive-warp strands. The system includes a plurality of heddles that receive the warp strands, and a plurality of harnesses coupled to the heddles. The dust-mitigating fabric has an adapter for receiving one or more phases of an electrical signal. The warp strands include a group of insulative-warp strands and one or more groups of conductive-warp strands. Each group of conductive-warp strands corresponds to a respective phase of the electrical signal. The harnesses move the groups of warp strands to form a shed, and move, on a group-by-group basis, each group of conductive-warp strands to facilitate forming the adapter. The system further includes a picking device to move a weft strand through the shed to form a fabric.

A coated substrate is disclosed, including a solvent-sensitive substrate and a polyester coating disposed on the solvent-sensitive substrate, wherein the polyester coating includes a polyester copolymer of a polyol and a polyacid. A method for forming a coated substrate is disclosed including spraying solvated polyester material from a spray nozzle onto a solvent-sensitive substrate and drying the solvated polyester material to form a polyester disposed on the solvent-sensitive substrate, wherein the solvated polyester material and the polyester coating include a polyester copolymer of a polyol and a polyacid.
