Abstract
A composite material having a black pigment and a textile material. The composite material has a reflectivity toward near infrared electromagnetic radiation having a wavelength from 800 nm to 2500 nm of greater than or equal to 12%, and the composite material has a reflectivity toward visible light having a wavelength from 350 nm to 750 nm of less than or equal to 10%.
Claims20
A composite material comprising:
- a black pigment;
- and
- a textile material, wherein
- the black pigment reflects less than 10% of incident visible electromagnetic radiation for all incident angles of the visible electromagnetic radiation between and including 0° and 45°,
- the composite material has a reflectivity toward a band of near infrared electromagnetic radiation within a wavelength from 800 nm to 2500 nm of greater than or equal to 12%, and
- the composite material has a reflectivity toward visible light having a wavelength from 350 nm to 750 nm of less than or equal to 10%.
A composite material fiber comprising:
- CuO;
- and
- a textile material, wherein
- the CuO has an average particle size less than or equal to 5 microns;
- the CuO dopes the textile material and forms a CuO-doped textile material mixture;
- and
- the composite material has a color with a lightness in CIELAB color space L* less than or equal to 40.
A method for making a black pigment-doped textile material, the method comprising:
- combining a black pigment with a textile material to form the black pigment-doped textile material, and
- extruding the black pigment-doped textile material, thereby producing a composite material fiber, wherein
- the black pigment reflects less than 10% of incident visible electromagnetic radiation for all incident angles of the visible electromagnetic radiation between and including 0° and 45°,
- the black pigment-doped textile material has a reflectivity toward a band of near infrared electromagnetic radiation within a wavelength from 800 nm to 2500 nm of greater than or equal to 12%, and
- the black pigment-doped textile material has a reflectivity toward visible light having a wavelength from 350 nm to 750 nm of less than or equal to 10%.
