  • Fabric permeable to ultraviolet radiations
    Patent number: 4115615
    Abstract: This invention relates to a fabric made from a polymer or of a miXture of polymers having an absorption curve of radiating energy characterized by a minimum absorption between 3,200 A and 4,000 A and an important filtering below 3,200 A, said polymer being eXtruded at a speed allowing an eXtremely quick cooling such that the formation of large crystallites is inhibited while promoting proliferation of crystallites of very small sizes.
