摘要： A yarn comprising a plurality of bicomponent filaments having a first region comprising a first polymer composition and a second region comprising a second polymer composition; the regions being distinct and present in the bicomponent filaments in a sheath-core structure or a side-by-side structure; wherein the first polymer composition comprises aramid polymer containing 0.5 to 20 weight percent homogeneously dispersed discrete carbon particles and the second polymer composition comprises aramid polymer being free of discrete carbon particles and having at least one homogeneously dispersed masking pigment, the yarn having a total content of 0.5 to 5 weight percent discrete carbon particles.
