Definitions

  • This invention relates to underwear comprising fibre containing metal and the object of the present invention is to provide underwear comprising fibre 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.
  • fibre 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 urethane fibre are popularly used, and these fibre materials are selected according to wearing seasons and are mixed-spun at an optimal ratio to form underwear.
  • underwear for summer is formed with fibre materials primarily comprising cotton in view of permeability and absorbency
  • underwear for winter has, in addition to said fibre materials, wool frequently mixed-spun to improve the heat-retaining properties.
  • This underwear uses fibre having far infrared irradiating materials like alumina, zirconia, or magnesia, contained in polyethylene- and polyamide-based fibre materials which show high permeability to far infrared radiation.
  • the fibre materials containing this far infrared irradiating materials are further covered with a protection layer, as part of the component fibre, and are formed in anticipation of the heat-retaining effect on wearing.
  • Underwear mixed-spun with wool gives sufficient heat-retaining effect if wool is mixed-spun at high ratio, but mixed-spinning wool at high ratio to increase the heat-retaining effect causes bulkiness of the underwear itself, generating a feeling that the underwear which is put directly on the skin does not fit well. This not only adversely affects wear comfort but also restricts movement of the wearer, producing a problem that the underwear can not be worn readily.
  • underwear mixed with far infrared irradiating ceramics can eliminate the bulkiness as compared with underwear mixed-spun with wool but it has a problem that the intended effect is difficult to achieve unless a large area is covered with the fibre material containing the far infrared irradiating substance.
  • a covering layer is provided to protect the far infrared irradiating layer but this covering layer absorbs far infrared radiation, so that the far infrared radiation emitted from the ceramics is unable to be effectively used.
  • this underwear has a problem that the effect of the far infrared radiation is unable to work most effectively on the feeling of comfort when the underwear is put in contact with the skin, is unable to exhibit good thermal conductivity while it is worn, and skin temperature after it is worn, so that excellent heat-retaining effect cannot be expected.
  • JP-A-4 073 226 underwear which comprises fibres to which platinum and at least one of the metal oxides selected from alumina and silica are mixed.
  • underwear which provides superb wear comfort to wearers, results in a good contact feeling when it is put on, good thermal conductivity while it is worn, is comfortable to wear, and manifests an excellent heat-retaining property.
  • underwear comprising fibre containing platinum and a metal oxide, characterised in that it comprises fibre materials mixed-spun with polyurethane elastic fibre in the range of 2-50%, to which platinum and at least one metal oxide selected from alumina, silica, titania are mixed.
  • underwear comprising fibre containing metal relating to the present invention
  • the fibre material mixed-spun with 2-50% polyurethane elastic fibre mixed with at least one metal oxide selected from alumina (Al 2 O 3 ), silica (SiO 2 ), and titania (TiO 2 ) as well as platinum (Pt) as essential components is designated as component fibre.
  • the alumina (Al 2 O 3 ), silica (SiO 2 ), or titania (TiO 2 ) used in the present invention is preferably in the powder form with grain size of 1 ⁇ or smaller, but there is no restriction.
  • the platinum (Pt) preferably has a grain size as fine as 7-40 ⁇ and is preferably in a colloidal form.
  • the mix ratio of these metal oxides and platinum is preferably about 9-45% alumina (Al 2 O 3 ), 50-80% silica (SiO 2 ), 8-15% each titania (TiO 2 ) and/or platinum (Pt), but there is no restriction.
  • oxides of calcium, zinc, and copper may be mixed by about 2-10%.
  • the metal oxides comprised as above emit electromagnetic radiation (far infrared radiation) with a 5-12 micron wavelength range. This range is effective for human bodies and is stably and sufficiently emitted even at the temperature range of around 30°C , as clear from the following tests.
  • polyurethane elastic fibre used is SPANDEX (SPANDEX is a Registered Trade Mark) which comprises a noncrystalline segments including either polyester or polyether portions and crystalline segments with urethane bonds and is popularly used in regular textile products.
  • SPANDEX is a Registered Trade Mark
  • other polyurethane elastic fibre may alternatively be used.
  • a method of mixing metal oxides and platinum to the polyurethane elastic fibre is not particularly specified but any of known method can be adopted as required, such as the method of mixing the polymerised fibre 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 fibre is not particularly specified but any blending ratio can be used if it results in the emission of 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, as well as successfully effecting contact feeling and thermal conductivity during wearing and manifesting satisfactory heat-retaining effect and is within the range that enables spinning and does not impair wear comfort as a component fibre material of underwear.
  • electromagnetic radiation far infrared radiation
  • polyurethane elastic fibre is particularly used is that mixed-spinning polyurethane elastic fibre 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 fibre 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.
  • the thermal conductivity and thereby the temperature variation in the body increase after the underwear is worn, and the blood flow rate at the wearing portion is easy to increase, so that a superior heat-retaining effect can be manifested.
  • polyurethane elastic fibre mixed with at least one of metal oxides selected from the above-mentioned alumina (Al 2 O 3 ), silica (SiO 2 ), and titania (TiO 2 ) as well as platinum (Pt) as essential components is mixed-spun with other regular fibre materials into underwear through a conventional method.
  • metal oxides selected from the above-mentioned alumina (Al 2 O 3 ), silica (SiO 2 ), and titania (TiO 2 ) as well as platinum (Pt) as essential components
  • the mixed-spinning ratio of polyurethane elastic fibre containing metal oxides is less than 2%, emission of electromagnetic radiation from metal oxides using the expandability of the above-mentioned polyurethane elastic fibre does not take place effectively and the superior heat-retaining property is not manifested. If the ratio exceeds 50%, a disagreeable touch is provided for the wearer and certain people may develop allergic symptoms, indicating that either of the cases is not desirable.
  • fibre materials to be mixed-spun with polyurethane elastic fibre ordinary natural and artificial fibre materials such as cotton, hemp, wool, acrylic, polyester, and nylon are favourably used and these fibre materials may be optimally mixed-spun to make underwear at an optional ratio, and are not particularly specified.
  • Regular men's underwear such as undershirts, athletic shirts, briefs, shorts, and drawers and regular ladies' underwear such as panties, tanks, panty hoses, semi-long sleeve and tee shirts are given as examples of underwear included in the present invention, but the invention is not limited to items in this list.
  • the underwear comprising fibre containing metal, which is characterised in comprising fibre material mixed-spun with 2-50% polyurethane elastic fibre, to which at least one metal oxide selected from alumina, silica, and titania as well as platinum are mixed as essential components, has hardly any bulkiness and has agreeable wear comfort such as flexibility and expandability which is ensured when the underwear is put on.
  • electromagnetic radiation far infrared radiation
  • metal oxides are emitted nearly in close contact with the wearer by making use of expandability of polyurethane elastic fibre, 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 both when the underwear is put on and thermal conductivity while it is worn, enabling manifestation of an excellent heat-retaining effect.
  • underwear comprising fibre containing metal according to the present invention
  • polyurethane elastic fibre mixed with metal oxides comprising alumina (Al 2 O 3 ), silica (SiO 2 ), titania (TiO 2 ), and platinum (Pt) in the ratio 10:82:3:5 was mixed-spun with 85% cotton and made into ladies' tee shirts by an ordinary method.
  • metal oxides comprising alumina (Al 2 O 3 ), silica (SiO 2 ), titania (TiO 2 ), and platinum (Pt) in the ratio 10:82:3:5 was mixed-spun with 85% cotton and made into ladies' tee shirts by an ordinary method.
  • the ladies' underwear obtained in Example 1 and in Comparisons 1 through 3 were measured for various properties including density (g/m 2 ), thickness (cm), contact feeling (Q max), steady thermal conductivity (W/cm °C x 10 -4 ), and heat-retaining ratio (%) with THERMOLABO 2-KES7 (KATOHTEC: heat property measuring equipment).
  • the measurement was carried out on temperature retained by the underwear about 1200 seconds after it was put on and skin temperature of the back immediately after and about 66 seconds after the underwear was taken off.
  • thermograph NEC San-Ei 6T/62 type (HgCdTe sensor, 8-13 ⁇ m): infrared radiation thermometer - 50 - 2000°C).
  • Example 1 The ladies' underwear of Example 1 and Comparison 1 was respectively worn by two panelers, and the blood flow rate (ml/min/100g) was measured by the laser Doppler method (Journal of the Laser Medical Society of Japan Vol. 12, No. 1, 7. 1988) using the laser Doppler rheometer (ADVANST: ALF-21) when the underwear was worn for a specified period.
  • ADVANST ALF-21
  • the ladies' underwear containing metal oxides provides overall temperature variation difference 0.6°C higher on average than that of ladies' underwear not containing metal oxides (Comparison 1), showing higher heat-retaining effect.
  • the ladies' underwear of Example 1 tends to increase the blood flow rate by heat-retaining as compared with the ladies' underwear of Comparison 1.
