Difference Between Polyester and Polyester
Polyester Both polyester and polyester are synthetic fibers, and while they have similar chemical structures, there are significant differences in many ways. This article will detail the differences between these two types of fibers. 
1. Raw materials and production process.
Polyester, also known as polyester, is a polymer synthesized from terephthalic acid and ethylene glycol through esterification and polycondensation reactions. However, the production process for polyester fibers is slightly different. It is a long-chain macromolecule made of polyester repeat units that are made into fibers through a specific spinning process.
Second, performance characteristics.
Strength and abrasion resistance: Polyester has high strength and good wear resistance, so it is often used to make products that need to withstand large external forces, such as ropes, fishing nets, etc. Although the strength of polyester fiber is not as strong as polyester, it can meet the demand in many textiles.
Wrinkle resistance: Polyester has good wrinkle resistance and is not easy to wrinkle. In contrast, polyester fibers are less wrinkle resistant and prone to creases.
Elasticity: The elasticity of polyester is better than that of polyester fibers, so polyester products can still maintain a good shape after many uses. Polyester fiber products are easy to deform after repeated use.
Heat resistance: Polyester has better heat resistance and can withstand higher temperatures, while polyester fiber has relatively poor heat resistance.
Moisture absorption: Polyester fiber has good moisture absorption, is comfortable to wear, and is suitable for wearing in a variety of climatic conditions. Polyester is less hygroscopic, but quick-drying is better than polyester.
3. Use. Since polyester and polyester fibers differ in performance, their uses are also different. Polyester is widely used in outdoor products, sportswear, bedding and other fields due to its excellent abrasion resistance and quick-drying properties. Polyester fibers are often used to make textiles such as intimate clothing, bed sheets, curtains, etc., because of their good moisture absorption and soft hand feel.
Fourth, summary. Although polyester and polyester fibers are both synthetic fibers, there are significant differences in raw material production, performance characteristics and uses. Polyester has high strength, abrasion resistance, and wrinkle resistance, while polyester fiber has good moisture absorption and elasticity. Knowing the difference between the two fibers can help you better choose the right textiles and materials for your needs.
