Definitions

  • This invention relates to underwear comprising fiber containing metal and the object of the present invention is to provide underwear comprising fiber containing metal which not only provides flexibility and excellent smooth touch when it is put on and agreeable wear comfort while it is worn but also manifests an extremely good heat-retaining effect that the underwear provides unnoticeable contact feeling when it is put on and small thermal conductivity while it is worn and the blood flow rate tends to rise at the wearing portion.
  • fiber materials forming men's underwear such as long-sleeved shirts, shirts with half-length sleeves, and drawers, and ladies' tee shirts, semi-long-sleeved shirts and panties, cotton, nylon, polyester, acrylic, and urethanefiber are popularly used, and these fiber materials are properly selected according to wearing seasons and mixed-spun at an optional ratio to form underwear.
  • underwear for summer is formed with fiber materials primarily comprising cotton in view of permeability and absorbency
  • underwear for winter in addition to said fiber materials, wool is frequently mixed-spun to improve heat-retaining property.
  • This underwear uses fiber having far infrared irradiating materials like alumina, girconia, or magnesia, contained in polyethylene- and polyamide-based fiber materials which show high permeability to far infrared radiation and the fiber materials containing this far infrared irradiating materials further covered with a protection layer, as part of the component fiber, and are formed in anticipaction of the heat-retaining effect by wearing.
  • far infrared irradiating materials like alumina, girconia, or magnesia
  • the underwear mixed with far infrared irradiating ceramics can eliminate the bulkiness as compared with said underwear mixed-spun with wool but it has a problem that the intended effect is difficult to be achieved unless a large area is covered with the fiber material containing far infrared irradiating substance.
  • this underwear has a problem that effect by the far infrared radiation is unable to work most effectively on the contact feeling when the underwear is put on, thermal conductivity while it is worn, and skin temperature after it is worn, so that the excellent heat-retaining effect cannot be expected.
  • underwear comprising fiber containing metal which is characterized in comprising fiber materials mixed-spun with polyurethane elastic fiber in the range of 2-50%, to which at least one of metal oxides selected from alumina, silica, and titania as well as platinum are mixed as essential components.
  • underwear comprising fiber containing metal relating to the present invention
  • the fiber material mixed-spun with 2-50% polyurethane elastic fiber mixed with at least one of metal oxides selected from alumina (Al2O3), silica (SiO2), and titania (TiO2) as well as platinum (Pt) as essential components is designated as component fiber.
  • alumina (Al2O3), silia (SiO2), and titania (TiO2) used in the present invention those in the powder form with grain size of 1 ⁇ or smaller are favorably used, but there is no restriction.
  • platinum that with grain size as fine as 7-40 ⁇ and in a colloidal form is preferably used.
  • the mix ratio of these metal oxides and platinum is about 9-45% alumina (Al2O3), 50-80% silica (SiO2), 8-15% each titania (TiO2) and/or platinum (Pt), but there is no restriction.
  • oxides of calcium, zinc, and copper may be mixed by about 2-10%.
  • electromagnetic radiation far infrared radiation
  • a 5-12 micron wavelength range to be effective for human bodies are stably and sufficiently emitted even at the tempeature range of around 30°C, as clear from the following tests.
  • SPANDEX which comprises a noncrystalline segments including either polyester or polyether portions and crystalline segment with urethane bonds and is popularly used in regular textile products is favorably used.
  • a method to mix metal oxides and platinum to said polyurethane elastic fiber is not particularly specified but any of the optional methods can be adopted as required, such as the method to mix the polymerized fiber material solution dispersedly in the solution before dry spinning or mix into the dry-spun yarns.
  • the blending ratio of metal oxides mixed in polyurethane elastic fiber is not particularly specified but any of the blending ratio can be favorably adopted if it is the blending ratio which emitts electromagnetic radiation (far infrared radiation) with a wavelength range of about 5-12 microns to be effective for human bodies at the temperature around 30 °C , successfully effects contact feeling and thermal conductivity during wearing and manifests satisfactory heat-retaining effect and is within the range that enables to spin and that does not impair wear comfort as a component fiber material of underwear.
  • electromagnetic radiation far infrared radiation
  • the reason why polyurethane elastic fiber is particularly used is that mixed-spinning polyurethane elastic fiber with generous expandability results in improved wear comfort of underwear and at the same time mixing the above-mentioned metal oxides and platinum to this polyurethane elastic fiber enables emission of electromagnetic radiation (far infrared radiation) from the metal oxides into the body with the underwear closely in contact with the body of the wearer, makes the best use of the effect of emitted electromagnetic radiation (far infrared radiation), and allows the electromagnetic radiation (far infrared radiation) to work effectively on the contact feeling when the underwear is put on and the thermal conductivity, thereby temperature variation in the body increases after the underwear is worn, and the blood flow rate at the wearing portion is easy to increase, as a result, a superior heat-retaining effect can be manifested.
  • electromagnetic radiation far infrared radiation
  • polyurethane elastic fiber mixed with at least one of metal oxides selected from the above-mentioned alumina (Al2O3), silica (SiO2), and titania (TiO2) as well as platinum (Pt) as essential components is mixed-spun with other regular fiber materials into underwear through a regular method.
  • metal oxides selected from the above-mentioned alumina (Al2O3), silica (SiO2), and titania (TiO2) as well as platinum (Pt) as essential components
  • fiber materials to be mixed-spun with polyurethane elastic fiber ordinary natural and artificial fiber materials such as cotton, hemp, wool, acrylic, polyester, and nylon are favorably used and these fiber materials may be optimally mixed-spun to make underwear at an optional ratio, and are not particularly specified.
  • underwear made by mixed-spinning cotton fiber in such a manner that the cotton fiber is lacated on the side in contact with the human body is favorably worn in the wintertime due to heat-retaining property of the cotton fiber.
  • underwear made by mixed-spinning the cotton fiber in such a manner that this cotton fiber is located opposite the side in contact with the human body is favorably worn in the summertime due to the heat dissipation property of the cotton fiber.
  • Regular men's underwear such as undershirts, athletic shirts, briefs, shorts, and drawers and regular ladies' unde rwear such as panties, tanks, panty hoses, semi-long sleeve and tee shirts are given as examples of underwear included in the present invention, but not limited to.
  • the present invention relates to the underwear comprising the fiber containing metal, which is charcterized in comprising fiber material mixed-spun with more than 2-50% polyurethane elastic fiber, to which at least one of metal oxides selected from alumina, silica, and titania as well as platinum are mixed as essential components, bulkiness of the underwear itself hardly exists and agreeable wear comfort such as flexibility and expandability is ensured when the underwear is put on, and at the same time because electromagnetic radiation (far infrared radiation) by metal oxides is emitted nearly in close contact with the wearer by making use of expandability of polyurethane elastic fiber, as clear from the results of said tests, electromagnetic radiation (far infrared radiation) is permitted to work effectively on contact feeling of the wearing portion as well as when the underwear is put on and thermal conductivity while it is worn, enabling manifeststion of an extremely excellent heat-retaining effect.
