Disclosed are exemplary embodiments of woven geotextile fabrics. In exemplary embodiments, a geotextile has a high water flow rate, such as a water flow rate of at least 125 gallons per minute per square foot, etc.

Towel cloth is provided, which has bulky and fluffy hand, of which hand hardly changes and fluff drop hardly occurs during washing, of which a dewatering property is favorable and dries rapidly after washing, and which also has water absorbability. Towel cloth in which a pile yarn is locked to a ground yarn, wherein the pile yarn is constituted by a twisted union yarn of a non-crimpable polyester-based multifilament yarn and a vegetable fiber.

Disclosed are exemplary embodiments of woven filtration fabrics that include core-sheath spun yarns in either or both of the warp and weft directions.

A sheet of material suitable for roofing or industrial wrapping applications has an anti-skid surface formed by ridges of twisted tapes. The sheet comprises a woven scrim of warp tapes and weft tapes. Some of the tapes are twisted about their longitudinal axis, for example about (25) to (400) revolutions per meter, to form ridges having a height substantially greater than the thickness of the tapes. The ridges impart an anti-skid surface to the sheet. The scrim is bonded to a coating or film to make the sheet waterproof.

An air bag base cloth according to the present invention includes a synthetic fiber fabric constituted by warp and weft that are constituted by synthetic fibers, and a synthetic resin layer that coats at least one surface of the synthetic fiber fabric, and only threads in one of the warp and the weft of the synthetic fiber fabric are exposed from the synthetic resin layer.

The purpose of the present invention is to improve thermal stability in a lightweight woven fabric that is useful for air bag applications and the like. This woven fabric comprises synthetic fibers, and is characterized in that, with regard to a rising temperature differential scanning calorimetry (DSC) endothermic curve for the woven fabric, the ratio of the amount of heat absorbed on the high temperature side of the maximum temperature of the melting endotherm on the rising temperature DSC endothermic curve for a woven fabric structure, to the overall heat absorbed exceeds 45%.

A method for manufacturing a nylon 66 hollow fiber includes steps as follows. A plurality of nylon 66 particles are provided. A melting step is provided, wherein the nylon 66 particles are melted so as to form a spun liquid. A fiber spitting step is provided, wherein the spun liquid goes through a hollow spinneret plate so as to form hollow nascent fibers. An evacuating step is provided, wherein the hollow nascent fibers are preliminarily solidified so as to form hollow half-solidified fibers. A cooling step is provided, wherein the hollow half-solidified fibers are cooled and solidified so as to form solidified fibers. A collecting and oiling step is provided. A drawing step is provided. A winding step is provided so as to obtain the nylon 66 hollow fiber.

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.
