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).

Depending on the chemical structure, polyester can be a thermoplastic or thermosets. However, the most common polyesters are thermoplastics.

Types:According to procedure of polyester, there are two types.

Natural PolyesterSynthetic Polyester

Natural polyesters and a few synthetic ones are biodegradable, but most synthetic polyesters are not.

Preparation of Polyesters:

POLYESTER RESINPolyester resins are used in sheet moulding compound, bulk moulding compound and the toner of laser printers. Wall panels fabricated from polyester resins reinforced with fiberglass — so-called fiberglass reinforced plastic (FRP) — are typically used in restaurants, kitchens, restrooms and other areas that require washable low-maintenance walls.

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.

Use of polyester in garments

Wrinkle resistant:using the nature of wrinkle resistant, it is used very often in everyday clothing like pants, shirts, tops, skirts and suits. Used either by itself or as a blend, it is also stain resistant and hence very popular.
