  • Yarn from polymers having different decomposition temperatures and process for forming same
    Patent number: 10954609
    Abstract: This invention relates to a yarn, and a process for making the yarn, the yarn comprising a plurality of spun filaments having a distinct, continuous, uniform-density sheath of a first polymer surrounding a distinct, continuous core of a second polymer; the first polymer further having a thermal decomposition temperature at least 50 degrees Celsius lower than the thermal decomposition temperature of the second polymer.
    Type: Grant

  • ARTICLES COMPRISING LOW TEMPERATURE HEAT-SEALABLE POLYESTER
    Publication number: 20170136747
    Abstract: An article such as a film or sheet comprises a heat-sealable polyester composition having an amorphous processing window ranging from a Tg in the range of about 40 to about 70° C., to a Tcg in the range of about 70 to about 150° C. The composition comprises poly(trimethylene furandicarboxylate) homopolymer or copolymer, or a blend of poly(trimethylene furandicarboxylate) homopolymer or copolymer with other polymers such as poly(alkylene furandicarboxylate) homopolymer or copolymer or poly(alkylene terephthalate) homopolymer or copolymer. The resulting composition is heat-sealable at low temperatures, and exhibits superior barrier properties compared to poly(ethylene terephthalate).
