PharmacokineticsIn all studied species (horse, dog, cattle and sheep) the pharmacokinetics of xylazine is best described by a 2-compartment model with a rapid distribution phase. The half-life of distribution is Â½-6 minutes and the half-life of elimination is 23-50 minutes, depending on species.
Polyester is a synthetic fiber derived from coal, air, water, and petroleum. Developed in a 20th-century laboratory, polyester fibers are formed from a chemical reaction between an acid and alcohol. In this reaction, two or more molecules combine to make a large molecule whose structure repeats throughout its length.
The most widely used polyester fiber is made from the linear polymer poly (ethylene terephtalate), and this polyester class is generally referred to simply as PET. High strength, high modulus, low _shrinkage, heat set stability, light fastness and chemical resistance account for the great versatility of PET.dditional current U.S. Polyester Fiber Producers are: Acordis Industrial Fibers, Inc.; AlliedSignal Inc; Cookson Fibers, Inc.; KoSa; Intercontinental Polymers, Inc., Martin Color-Fi. Nan Ya Plastics Corp., Wellman, Inc. [24] Dramatic growth in PET fiber production is foreseen in Asia in the near future [22].
