What is the difference between polyester and spandex(2)?


2. Different uses

Because polyester is an artificial fiber, it can be blended with cotton, linen and wool to make various fabrics. Due to its strong pressure resistance and resistance to exposure to sunlight, it can be made into fishing nets, ropes, tire cords, etc. in industry, and can also be used as insulating materials.
Spandex is most famous for its elasticity. Using its elasticity, it is widely used in underwear, panties, tights, casual wear and sportswear. It also has applications in the medical field: bandages are also made of spandex.

3. Different strengths

The short fiber strength of polyester is 2.6-5.7cN/dtex, and the high-strength fiber is 5.6-8.0cN/dtex. Due to its high strength, it is widely used in ropes, fishing nets and other tools with high strength requirements.
Spandex has poor strength, so in terms of strength, polyester is the best.
