    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.

    Abstract: A woven security label is woven from threads of synthetic fiber, which interweaves a piece of check warp or weft yarn. The check warp or weft yarn comprises one or more pieces of detectable filament containing a small amount of inorganic fluorescent substance. The check warp or weft yarn is substantially colorless in ordinary sunlight, electric light or the like but reversibly changes color under influence of specific UV light.
