  • Polymer blends of trimethylene terphthalate and an elastomeric polyester
    Patent number: 6462145
    Abstract: A polymer blend consisting essentially of 80% to 95% by weight, based on the total weight of the composition, of polytrimethylene terephthalate and from 5% to 20% of an elastomeric polyester. Fibers and extrusions produced from the polymer blend are durable under repetitive compressive stresses, exhibit mechanical properties comparable to neat polyamide-6, and provide moisture stability similar to yarns and extrusions comprised of polyamide-6/10 or polyamide-6/12. These fabrics find use as forming fabrics, and press felt fabrics for paper making machines.
