Title:
ULTRAAVIOLET RAY PERMEABLE FABRIC
Document Type and Number:
Japanese Patent JPS52155273
Kind Code:
A
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.
