The bicomponent yarn is preferably of the sheath-core type of which only the core contains a black pigment composed of carbon black particles and/or a reddish pigment composed of iron oxide particles and/or a whitish pigment composed of titanium dioxide particles of the rutil type, which pigments are insoluble in the polymeric material. The tenacity of the yarn may be about 70-85 cN/tex and the elongation at rupture of 7 to 15%.
