Abstract
A composite protective yarn is incorporated into an article of apparel. The protective yarn has a core unit including a protective material selected from a group consisting of metallic filament, glass, and high tenacity fiber having a tensile strength of at least 7 grams per denier. A cover is applied to the core unit and is adapted for residing adjacent the skin. The cover includes an optically responsive material adapted for absorbing infrared radiation emitted from the human body at a first wavelength and returning the absorbed radiation to the body at a second longer wavelength. This relaxes capillaries and promotes increased blood flow to body parts covered by the article of apparel.
Claims23
A composite protective yarn for being incorporated into an article of apparel, said protective yarn comprising:
- (a) a core unit comprising a protective material selected from a group consisting of metallic, glass, and high tenacity fiber having a tensile strength of at least 7 grams per denier;
- and
- (b) a cover applied to said core unit and adapted for residing adjacent the skin, said cover comprising an optically responsive material adapted for absorbing infrared radiation emitted from the human body at a first wavelength and returning the absorbed radiation to the body at a second longer wavelength, thereby relaxing capillaries and promoting increased blood flow to body parts covered by the article of apparel.
A protective yarn for being incorporated into an article of apparel, said protective yarn comprising:
- (a) a core unit comprising a protective material selected from a group consisting of metallic filament, glass, and high tenacity fiber having a tensile strength of at least 7 grams per denier;
- and
- (b) a cover applied to said core unit and adapted for residing adjacent the skin, said cover comprising an optically responsive material adapted for absorbing infrared radiation emitted from the human body at a first wavelength and returning the absorbed radiation to the body at a second longer wavelength, thereby relaxing capillaries and promoting increased blood flow to body parts covered by the article of apparel, and said optically responsive material comprising a resin composition extruded to form a continuous filament cover strand adapted for wrapping around and encasing said core unit.
An article of apparel including a protective, flexible yarn comprising:
- (a) a core unit comprising a protective material selected from a group consisting of metallic filament, glass, and high tenacity fiber having a tensile strength of at least 7 grams per denier;
- and
- (b) a cover applied to said core unit and adapted for residing adjacent the skin, said cover comprising an optically responsive material adapted for absorbing infrared radiation emitted from the human body at a first wavelength and returning the absorbed radiation to the body at a second longer wavelength, thereby relaxing capillaries and promoting increased blood flow to body parts covered by the article of apparel.
A multi-component protective fabric adapted for incorporating into an article of apparel, said fabric comprising:
- (a) an inner fabric layer comprising a yarn adapted for residing primarily adjacent the skin, said yarn including an optically responsive material adapted for absorbing infrared radiation emitted from the human body at a first wavelength and returning the absorbed radiation to the body at a second longer wavelength, thereby relaxing capillaries and promoting increased blood flow to body parts covered by the article of apparel;
- (b) an outer fabric layer comprising a yarn including a protective material selected from a group consisting of metallic, glass, and high tenacity fiber having a tensile strength of at least 7 grams per denier;
- and
- (c) wherein said inner and outer fabric layers are formed concurrently by knitting a plaited construction.
