Glenn Allan Stahl, James John McAlpin: Fibers and fabrics incorporating lower melting propylene polymers. Exxon Chemical Co, Douglas W Miller, March 10, 1998: US05726103 (37 worldwide citation)

Propylene homopolymers and copolymers formed by metallocene catalyst system exhibit generally lower melting behavior than previous propylene polymers. This lower melting behavior will be of use in the fabrication and use of fibers and fabrics that depend upon either lower melting behavior in general ...
