Squiggle Mini Sequins Spandex is generally mixed with cotton or polyester, and accounts for a small percentage of the final fabric, which therefore retains most of the look and feel of the other fibers. Because of its elasticity and strength (resistance to 600% elongation before rupture), spandex has been incorporated into a wide range of garments, especially in skin-tight garments. For example: activewear, costumes, and dresses. A benefit of spandex is its significant strength and elasticity and its ability to return to the original shape after stretching and faster drying than ordinary fabrics.
