Plexifilamentary strands of polyester

   
   

A process for producing plexifilamentary or foam products by flash spinning in selected spin agents a polymer from the group consisting of poly (1,3-propylene terephthalate), poly (1,4-butylene terephthalate), and poly(ethylene terephthalate), including their copolymers in which the spin agents have minimal or no ozone-depleting properties.
