What is the Difference Between Dacron and Polyester?

Dacron and polyester are related but not the same. The key difference between dacron and polyester is that Dacron is a form of polyester, whereas polyester is a polymer material composed of ester groups attached to the main chain.

• Dacron: Dacron is a specific brand name for a type of polyester, also known as polyethylene terephthalate (PET). It is a polymer material found in the polyester family and is known for its strength, durability, and resistance to abrasion. Dacron is a thermoplastic polymer material and is used in various applications, such as fibers for clothing, storage containers for food and beverage, and thermoplastic resins. It was first introduced by DuPont, an American fiber manufacturer, in 1950.
• Polyester: Polyester is a group of materials composed of at least 85% by weight of an ester and a dihydric alcohol. It is formed through the reaction between carboxylic acids and alcohols, which forms esters. Polyester is widely used in the textile and apparel industry to make clothing, footwear, and accessories, as well as in domestic products like mattresses, pillows, cushions, and upholstery.

In summary, Dacron is a brand name of polyethylene terephthalate (PET) and is a member of the polyester family, while polyester is a broader category of materials composed of ester groups attached to the main chain.
