摘要:
Disclosed is a process for injection stretch blow molding a thermoplastic composition comprising, consisting essentially of, or prepared from (a) about 30 to about 99 weight % based on the combination of (a) and (b) of a poly(ethylene terephthalate) homopolymer or copolymer; and (b) about 1 to about 70 weight % based on the combination of (a) and (b) of a poly(trimethylene terephthalate) homopolymer or copolymer, wherein the composition does not contain a crystallization accelerator.
摘要:
Fluorescent poly(alkylene terephthalate) compositions are provided. The fluorescent poly(alkylene terephthalate) compositions contain fluorescent poly(alkylene terephthalate)s and are made from fluorescent compounds and poly(alkylene terephthalate) oligomers, or by polymerizing amine and acid monomers in the presence of fluorescent compounds.
摘要:
A bicomponent fiber wherein (a) the first component comprises from about 90 to 100 wt. % poly(trimethylene terephthalate) and (b) the second component is a polymer composition comprising (i) poly(trimethylene terephthalate) and (ii) polymer containing polyalkylene ether repeating units. Yarn, fiber, fabrics and carpets comprising the bicomponent fiber, as well as the process of making the bicomponent fiber, yarn, fabric, and carpet.
摘要:
Highly crimped, fully drawn bicomponent fibers, prepared by melt-spinning, followed by gas-flow quenching, heat treatment and high speed windup, are provided, as are fine-decitex and highly uniform polyester bicomponent fibers.
摘要:
The present invention provides a heat-sealable polyester composition having an amorphous processing window ranging from a Tg in the range of about 40° C. to about 70° C., to a Tcg in the range of about 70° C. to about 150° C. The composition preferably contains a mixture of poly(ethylene terephthalate) homopolymer or copolymer and poly(trimethylene terephthalate) homopolymer or copolymer, either as a physical blend or as a copolyester oligomer or polymer prepared from the respective monomers. The resulting composition is heat-sealable at low temperatures, retains barrier properties and is non-flavor-scalping.
