Abstract:
The present invention is directed to new chenille yarns and methods of making the same. The present invention is further directed to new chenille yarns having a spun core containing low-melting staple-length binder fibers and methods of making the same. The chenille yarns may be used on conventional weaving equipment, including air jet and water jet weaving machines, to produce simulated pile fabrics having superior abrasion resistance and improved hand. The present invention is, also directed to methods of making fabrics containing the chenille yarn, and various uses for the fabrics, especially as residential upholstery fabrics, decorative throws, contract fabrics, automotive fabrics, and bedding fabrics for use in the home.
Abstract:
Disclosed is a polyethylene glycol modified copolyester fiber that has exceptional moisture management characteristics and that can be formed into exceptionally comfortable fabrics. The copolyester fiber includes polyethylene terephthalate in an amount sufficient for the copolyester fiber to possess dimensional stability properties substantially similar to those of conventional, unmodified polyethylene terephthalate fibers, polyethylene glycol in an amount sufficient for the copolyester fiber to possess wicking properties that are superior to those of conventional, unmodified polyethylene terephthalate fibers, and chain branching agent in an amount less than about 0.0014 mole-equivalent branches per mole of standardized polymer.
Abstract:
Disclosed is a method of copolymerizing polyethylene glycol (PEG) into polyethylene terephthalate (PET) to achieve a polyethylene glycol-modified polyester composition that can be spun into filaments. The method includes the steps of copolymerizing polyethylene glycol into polyethylene terephthalate in the melt phase to form a copolyester composition, then polymerizing the copolyester composition in the solid phase until the copolyester is capable of achieving a melt viscosity that facilitates the spinning of filaments, and thereafter spinning filaments from the copolyester. A copolyester composition comprised of polyethylene glycol and polyethylene terephthalate is also disclosed. Fabrics made from fibers formed from the copolyester composition possess wetting, wicking, drying, flame-retardancy, static-dissipation, and soft hand properties that are superior to those of fabrics formed from conventional polyethylene terephthalate fibers of the same yarn and fabric construction.
