Abstract: A core-sheath fiber has a core and a sheath. The core comprises 0.1 to 10 wt % of carbon black pigment particles. The sheath surrounds the core preventing the core from being exposed. Because the carbon black pigment particles are mainly distributed in the core and the core is surrounded by the sheath with little or no carbon black pigment particles, a surface of the core-sheath fiber has low friction and electrical conductivity. Therefore, a lifetime of a punch needle used in machinery to produce a nonwoven is maintained and the nonwoven can undergo high frequency treatment to form artificial leather. Additionally, the sheath has little or no carbon black pigment particles, so the sheath is improved compatibility with polyurethane (PU) used for high frequency treatment.
