Kind Code:
A
Abstract:
To provide a core-sheath-type polyester composite fiber excellent in deodorant property, antibacterial property, spinnability and processability.SOLUTION: There is provided a core-sheath-type polyester composite fiber having a core part constituted by polyester A and a sheath part constituted by 100 pts.mass of polyester B and 1.5 to 5.0 pts.mass of a polyester resin composition B containing deodorant fine particles, and satisfying following (1) to (3). (1) The deodorant fine particles mainly contain zinc oxide and silicon dioxide, and a mass ratio of the zinc oxide and the silicon dioxide is (zinc oxide):(silicon dioxide)=15:85 to 40:60. (2) Average particle diameter of the deodorant fine particles is 0.1 to 2.0 μm. (3) An oil agent is adhered to a surface of a single fiber and adhered amount of the oil agent is 0.5 to 3.0 mass% based on all mass of a constitutional fiber.SELECTED DRAWING: None
