Sun protective fabric

Abstract

Wrinkled fabrics comprising ultraviolet absorbers are disclosed which provide improvements in ultraviolet transmission, wearer comfort, and cost over those of the prior art. The preferred fabric is polyester and the preferred UV absorbers are chlorobenzotriazoles. The polyester is wrinkled permanently so as to provide an extra barrier to ultraviolet radiation from solely utilizing UV absorbers alone. This wrinkled product is also more comfortable to a wearer, particularly in warm weather or hotter climates. Other non-apparel uses are also contemplated including tents, awnings, and crowd covers. A method of making such a fabric is also disclosed comprising stuffing a jet dyeing machine with a more than normal load amount of fabric and eventually heat setting such resultant wrinkles into the finished product.
