1. Different characteristics
Polyester is an artificial fiber with the characteristics of artificial fiber, high strength, strong pressure resistance, heat resistance, and the strength can be maintained at 60% to 70% after a thousand hours of exposure to the sun. The resulting fabric has poor hygroscopicity.

Spandex, like polyester, is also an artificial fiber, but the biggest difference with polyester is that spandex is not pressure-resistant. What it has in common with polyester is that it has poor hygroscopicity. Spandex has its own unique characteristics, its elasticity is very good, professional tests show that spandex can be 5 to 7 times longer than its original length, and at the same time it is light-resistant and wear-resistant.
