Infrared-transparent visible-opaque fabrics for wearable personal thermal management.
First claim
Opening claim text (preview).
We claim: 1. A radiative cooling fabric comprising woven yarn, wherein the woven yarn substantially comprises fibers having a diameter of about 1 μm, and the average separation between yarn ranges from about 3 μm to about 100 μm. 2. The radiative cooling fabric of claim 1 , wherein the average separation between the fibers ranges from about 3 μm to about 10 μm. 3. The radiative cooling fabric of claim 1 , wherein the IR transmittance at wavelengths between about 5 μm to about 30 μm ranges from about 30% to about 90%, and the visible reflectance between about 300 nm to about 800 nm ranges from about 40% to about 60%. 4. The radiative cooling fabric of claim 1 , wherein the fabric has a porosity of about 0.1 to about 0.2. 5. The radiative cooling fabric of claim 1 , wherein the yarn has an average diameter ranging from about 30 μm to about 300 μm. 6. The radiative cooling fabric of claim 1 , wherein the fibers comprise polyester, cellulose, cellulose acetate, polyethylene, polypropylene, or nylon. 7. The radiative cooling fabric of claim 1 , wherein the fibers consist essentially of one polymer. 8. The radiative cooling fabric of claim 6 , wherein the fibers comprise 2 or more polymers. 9. The radiative cooling fabric of claim 8 , wherein the fibers have a core-sheath structure. 10. The radiative cooling fabric of claim 1 , wherein the yarn comprises fibers of polyester, cellulose, cellulose acetate, polyethylene, polypropylene, or nylon. 11. The radiative cooling fabric of claim 1 , wherein the yarn comprises fibers having substantially the same composition. 12. The radiative cooling fabric of claim 1 , wherein the yarn comprises 2 or more types of fibers. 13. The radiative cooling fabric of claim 1 , wherein the fabric comprises 2 or more types of yarns. 14. The radiative cooling fabric of claim 1 , further comprising at least one dye. 15. A garment comprising the fabric of claim 1 . 16. The garment of claim 15 , further comprising at least one dye.
