Spandex Testing

Spandex, also known as Lycra, or elastane, is a synthetic fiber known for its exceptional elasticity and high breathability. The composition of this fabric is polyether-polyurea copolymer. Spandex also has better resistance to acid and alkali, sweat, seawater, dry cleaning and abrasion. It is commonly used to make athletic wear, stretch pants, yoga pants, skinny jeans, underwear, bras, socks, motion capture suits.
