ABSTRACT:
This invention relates to knitting and textile for underwear, socks and stockings comprising fiber containing metal, which includes fiber materials mixed-spun with 2-50% polyurethane elastic fiber to which platinum and at least one metal oxide selected from the group consisting of alumina, silica, and titania are mixed as essential components. The metal oxides or platinum are mixed in the polyurethane elastic fiber to provide expandability. Electromagnetic radiation (far infrared radiation) liberated from the metal oxides is emitted in close contact with the human body, permitting infrared radiation to warm the body.
