FUNCTIONAL POLYESTER FIBER CONTAINING METALLIC INORGANIC CERAMIC HAVING ANTIBACTERIAL PROPERTY AND CERAMIC POWDER RADIATING FAR INFRARED RAY AND ANION

摘要

PURPOSE: Functional polyester fiber is characterized by having excellent antibacterial property and radiating far infrared ray and anion. The fiber is useful for underclothes, clothes, socks, stockings and a cover for bedclothes having excellent thermo-keeping property and wearing effect. CONSTITUTION: Functional polyester fiber radiating far infrared ray, anion and antibacterial property contains: 0.01-5.0wt.% of at least one of ceramic powder selected from the group containing formula(1), formula(2) and formula(3); and 0.01-5.0wt.% of metallic inorganic ceramic containing silver, copper, zinc and nickel. The formula(1) is X1Y3Al6B3Si6(OH)4. In the formula(1), X is Na and/or Ca; Y is Mg, Li, Al and/or Fe2+; Al and OH are capable of being substituted others. The formula(2) is (Na,Ca)2(Al2Si3O10)·8H2O and contains derivative thereof. The formula(3) is (Ce, La, Th, Nd, Y)PO4 and contains derivative thereof.
