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.
Industrial polyester fibers, yarns and ropes are used in tyre reinforcements, fabrics for conveyor belts, safety belts, coated fabrics and plastic reinforcements with high-energy absorption. Polyester fiber is used as cushioning and insulating material in pillows, comforters and upholstery padding.Polyester fabrics are highly stain-resistantâ in fact, the only class of dyes which can be used to alter the color of polyester fabric are what are known is disperse dyes.Polyester fibers are sometimes spun together with natural fibers to produce a cloth with blended properties.olyester fabrics are highly stain-resistantâ in fact, the only class of dyes which can be used to alter the color of polyester fabric are what are known is disperse dyes.
