PURPOSE:The title composite fibers usable for clothing, having improved opacity regardless of the color of the core part, comprising the sheath part of specific shape having improved light scattering property and the core part comprising a colored substance. CONSTITUTION:The core part comprising a colored substance, e.g. carbon black, is combined with the sheath part, wherein pores are scattered in the cross section in the fiber direction to give opaque composite fibers having hollows on the fiber surfaces in the direction. The colored sheath part cannot be easily seen by the light scattering, and the fibers are usable for clothing. |
