In this guide, you’ll learn what spandex fabric is, how it’s used in real products, and how to choose the right spandex blend for your needs.
What Is Spandex Fabric?
Spandex is a synthetic fiber known for its ability to stretch significantly and return to its original shape.
👉 It is the American term for elastane, which is the international name for the same material.
