Abstract
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.
