What is Elastane (10%)?

Elastane, also known as spandex or lycra, is a synthetic fiber known for its exceptional elasticity. It is produced through the reaction of a polyether with a diisocyanate, which creates a long-chain polymer that is able to stretch extensively.

Elastane is used in clothing, especially activewear like leggings, to provide a comfortable stretch that allows for enhanced movement and fit. There is no significant health evidence regarding elastane as it is not consumed; it mainly comes in contact with the skin.

When you see elastane on a clothing label, it indicates that the fabric will have elastic properties, contributing to durability and ease of movement.
