Polyester is a category of polymers that contain the ester functional group in every repeat unit of their main chain. It is a synthetic fabric that is derived from petroleum, and it is one of the worlds most popular textiles, used in thousands of applications. Polyester fibers can form very long molecules that are very stable and strong, and they are used in a wide range of products, including clothing, home furnishings, and industrial fabrics. Some key properties and characteristics of polyester include:
-
Durability: Polyester is a very durable fabric, making it ideal for use in products that need to withstand wear and tear.
-
Stain resistance: Polyester is a hydrophobic material, meaning it is hard to absorb liquids. This makes it highly stain-resistant.
-
Affordability: Polyester is a relatively inexpensive fabric, making it a popular choice for many applications.
-
Thermoplasticity: Polyester is thermoplastic, meaning it can be melted and reformed. This property makes it easy to manufacture and process.
-
Hydrophobicity: Polyester is hydrophobic, meaning it does not absorb perspiration or other fluids, leaving the wearer with a moist, clammy feel.
Polyester is used in a wide range of products, including clothing, home furnishings, and industrial fabrics. While some forms of polyester are biodegradable, most of them are not, and polyester production and use contribute to pollution around the world.
