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.
Polyester is a very important manmade fiber. Polyester is produced with a long chain synthetic polymer with ester. Polyester is produced by melt spinning process. Here, I have given physical and chemical properties of polyester fiber which is important to know. Physical Properties of Polyester: Like cotton or other fiber, polyester fiber consists of some important physical properties. Important physical properties of polyester are given below. Tenacity: 5 â 7 gm/den.
