What is elastic made of?

Elastic is a stretchable material that is typically used in clothing and other textile applications to provide flexibility and form-fitting properties. It is made from a variety of materials, including rubber, spandex, and polyester. Rubber is a natural material that is derived from the latex sap of rubber trees, while spandex is a synthetic fiber that is highly elastic and resistant to wear and tear. Polyester is a man-made material that is often blended with other fibers to create elastic fabrics with different characteristics. Elastic is commonly used in waistbands, cuffs, and other areas of clothing where stretch and recovery are important.
