Polyester Polyester is a category of polymers which contain the ester functional group in their main chain. Polyester fiber is an economical product with water absorbency, wind resistance, water repellence, and quick dry function. Relatively short fiber and nylon products are particularly good at eliminating sweat, making it an excellent choice for sports clothing

Although there are many polyesters, the term "polyester" as a specific material most commonly refers to polyethylene terephthalate (PET).

Use of polyester in garments

Creating insulation:By creating hollow fibers it is also possible to build insulation into the polyester fiber. Air is trapped inside the fiber, which is then warmed by the heat of the body. This keeps the body warm in cold weather. Another method to build insulation is to use crimped polyester in a fiberfill. The crimp helps keep the warm air in. Polyester is an ideal fabric for this kind of insulation because it retains its shape. Cotton and wool tend to flatten over a period of time and loose the warming effect.
