  • VAPOR PHASE ASSISTED POST-CONSUMER POLYMER PROCESSING APPARATUS AND METHOD
    Publication number: 20150045462
    Abstract: Embodiments of the invention provide a process for processing post-consumer polymer. The polymer is contacted with a control medium having a carrier gas and a reactive vapor. Such a process is useful for processing post-consumer polymers with lower energy and reactants than with liquid reactants, and also promotes decontamination of the recycled polymer during the reaction.

  • Melt-extruded monofilament comprised of a blend of polyethylene terephthalate and a thermoplastic polyurethane
    Patent number: 5502120
    Abstract: This invention discloses a fiber suitable for a papermaker's forming fabric, comprising a blend of 60 to 90% by weight of a polyethylene terephthalate, together with 40 to 10% by weight of a thermoplastic polyurethane, which may be an ester or ether-based type. Additionally, it is contemplated that the blend may contain up to 5% by weight of a hydrolysis stabilizer. The high abrasion resistance of these blended monofilaments makes them particularly advantageous for use in replacing the nylon-6 and nylon-66 monofilaments currently used in paper machine forming fabrics.
