Antistatic yarns, fabrics and carpets incorporating such antistatic yarns, and fiber blends for making such antistatic yarns are disclosed wherein the antistatic yarns are formed such that at least about 35 percent by weight of the staple fibers present are conductive staple fibers, quasi-conductive staple fibers, or mixtures of conductive and quasi-conductive staple fibers. Conductive staple fibers may include metal staple fibers, metal-coated non- conductive polymer staple fibers, carbon-loaded polymer staple fibers, polymer staple fibers loaded with antimony-doped tin oxide, conductive polymer solution-coated non-conductive polymer staple fibers, inherently-conductive polymer staple fibers, and bicomponent staple fibers. Quasi-conductive staple fibers may include bicomponent quasi-conductive staple fibers. Continuous fibers and non-conductive staple fibers may also be present.
La présente invention concerne des fils, tissus, et tapis antistatiques constitués de fils antistatiques, ainsi que des mélanges de fibres destinés à la fabrication de ces ils antistatiques. Ces fils antistatiques sont formés de telle façon qu'au moins 35 pour cent en poids des fibres courtes présentes sont des fibres courtes conductrices, quasi conductrices, ou des mélanges de fibres courtes conductrices et quasi conductrices. Les fibres courtes conductrices peuvent contenir des fibres courtes métalliques, des fibres courtes de polymère isolant métallisé, des fibres courtes de polymère chargé de carbone, des fibres courtes de polymère chargé d'oxyde d'étain dopé d'antimoine, des fibres courtes de polymère isolant revêtu d'une solution de polymère conducteur, de fibres courtes de polymère intrinsèquement conducteur, et de fibres courtes à deux composants. Les fibres courtes quasi conductrices peuvent être constituées de fibres courtes quasi conductrices à deux composants. On peut aussi avoir des fibres continues et des fibres courtes non conductrices.
