PROBLEM TO BE SOLVED: To provide a composite fiber that exhibits excellent contact cool sensation and excellent feeling when its is made into a fabric, and also has excellent processability.SOLUTION: A core-sheath-type composite fiber includes a fiber-forming polymer as a sheath component and a polymer mainly composed of polyethylene as a core component. The fiber-forming polymer of the sheath component contains 1 to 15 wt.% of inorganic compound particles having a refractive index of 1.6 to 5 and an average grain diameter of 0.1 to 1.5 μm. |
