Polyester material is a synthetic fiber, also known as polyester or polyester fiber. Due to the presence of terephthalic acid and ethylene glycol in its raw materials, it is also known as polyester fiber. The initial polyester material was commercially produced from PET (polyethylene terephthalate) in the 1940s.

1. Strong wear resistance: Polyester fabric has high wear resistance and is not easily worn or torn.
2. Easy to dry and not easily deformed: Polyester fabric has poor moisture absorption, so it is not easy to absorb moisture. This characteristic makes polyester products easy to dry after washing and less prone to deformation due to moisture absorption and release.
3. Good dimensional stability: Polyester fabric can maintain good dimensional stability during processing and is not easily deformed due to changes in the external environment. This allows polyester products to maintain a good appearance and comfort during wear or use.
4. Easy to clean and maintain: Polyester fabric has strong resistance to stains and grease, making it easy to clean and maintain.
5. Rich color and pattern selection: Polyester fabric has high adaptability in dyeing and printing, and can achieve a variety of color and pattern designs.
