Cloth containing an organic fiber and having a fluorine compound attached to the cloth, and textile product comprising the cloth
An object is to provide a cloth containing an organic fiber, which is excellent in the oil repellency, dirt-removal property by washing and water-absorbing property, and a textile product produced using the cloth. A means for solution is attaching a specific fluorine-containing polymer to a cloth containing an organic fiber, with a quaternary ammonium salt if desired, and thus making the water-absorbing property in accordance with JIS L1018A method (the instillation method) 60 seconds or less and the oil repellency in accordance with AATCC118-1992 grade 4 or higher.
Fabrics containing expanded polytetrafluoroethylene fibers
Woven and knit fabrics containing expanded polytetrafluoroethylene (ePTFE) fibers and at least one other fiber are provided. The ePTFE fiber may be woven or knit as a single, non-twisted fiber, as part of a multifilament fiber, or may be twisted or braided with another fiber. The ePTFE fiber, whether alone or in combination with a weave fiber(s), may be utilized in either the warp and/or the weft direction. The woven and knit fabrics are concurrently breathable, lightweight, durable, drapable, and fast drying. The ePTFE fibers have a substantially rectangular configuration. In some embodiments, the woven or knit fabric is flame resistant. In addition, the woven and knit fabrics are quiet, soft, and drapable. Treatments may be provided to the surface of the ePTFE fiber and/or the fabrics to impart one or more desired functionality, such as, for example, oleophobicity, anti-microbial, contamination resistance, or UV stability.
Conformable Microporous Fiber and Woven Fabrics Containing Same
Expanded polytetrafluoroethylene (ePTFE) monofilament fibers and woven fabrics formed from the ePTFE fillers are provided, The ePTFE fibers have a substantially rectangular configuration, a density less than about 1.0 glee, and an aspect ratio greater than 15. Additionally, the ePTFE fibers are microporous and have a node and fibril structure. The ePTFE fiber may be woven into a fabric without first twisting the fiber. A polymer membrane and/or a textile may be laminated to the woven fabric to produce a laminated article. The ePTFE woven fabric simultaneously possesses high moisture vapor transmission (highly breathable) and high water entry pressure (water resistant). The woven fabric is quiet, soft, and drapable, making it especially suitable for use in garments, gloves and footwear applications. Treatments may be provided to the surface of the ePTFE fiber and/or the woven fabric to impart one or more desired functionality, such as, for example, oleophobicity).
