Title (EN) INTIMATE BLENDS OF CARBON-CONTAINING AND DYEABLE FLAME RESISTANT FIBERS
(FR) MÉLANGES INTIMES DE FIBRES RÉSISTANTES À LA FLAMME CONTENANT DU CARBONE ET POUVANT ÊTRE TEINTES
Abstract:
(EN) An intimate blend of staple fibers, and a yarn, fabric, and article of clothing providing surprising arc performance and coloration capability, comprising a mixture of a first staple fiber made from a flame resistant polymer that retains at least 90 percent of its weight when heated to 425 degrees Celsius at a rate of 10 degrees per minute and comprises 0.5 to 20 weight percent discrete homogeneously dispersed carbon particles; and either (a) a second staple fiber from a flame resistant polymer being free of discrete carbon particles and having an L* lightness coordinate of 70 or greater and being capable of accepting a dye or coloration, or (b) a second staple fiber blend being free of discrete carbon particles and comprising at least one second staple fiber from a flame resistant polymer and having an L* lightness coordinate of 70 or greater and being capable of accepting a dye or coloration; the mixture having a total content of 0.5 to 3 weight percent discrete carbon particles.
(FR) La présente invention concerne un mélange intime de fibres discontinues, ainsi qu'un fil, un tissu et un article de vêtement fournissant une performance d'arc et une capacité de coloration surprenantes, comprenant un mélange d'une première fibre discontinue fabriquée à partir d'un polymère ignifuge qui conserve au moins 90 pour cent de son poids lorsqu'elle est chauffée à 425 degrés Celsius à une vitesse de 10 degrés par minute et comprend 0,5 à 20 pour cent en poids de particules de carbone dispersées de manière homogène discrètes ; et soit (a) une seconde fibre discontinue provenant d'un polymère ignifuge étant exempte de particules de carbone discrètes et ayant une coordonnée de clarté L* de 70 ou plus et étant apte à accepter un colorant ou une coloration, ou (b) un second mélange de fibres discontinues étant exempt de particules de carbone discrètes et comprenant au moins une seconde fibre discontinue provenant d'un polymère ignifuge et ayant une coordonnée de clarté L* de 70 ou plus et étant apte à accepter un colorant ou une coloration ; le mélange ayant une teneur totale de 0,5 à 3 pour cent en poids de particules de carbone discrètes.
