What is Lycra? Lycra yarn and its properties.
lycra is a man-made elastic fibre invented which is also known as estomer or spandex.It’s remarkable properties of stretch and recovery enhance all fabrics and garments in which it is used, adding easy comfort and freedom of movement and improving fit and shape retention. Swimwear and lingerie owe their figure-flattering fit to lycra. All types of hosiery are softer, smoother-fitting and more durable thanks to lycra. In short, a little bit of lycra makes all types of apparel fit better, feel better and look better.
lycra belongs to the generic elastane classification of man-made fibres(known as spandex in the US and Canada) and is described in technical terms as a segmented polyurethane it is composed of “soft”, or flexible, segments bonded together with “hard”, or rigid, segments. This gives the fibre it’s built-in, lasting elasticity.lycra can be stretched four to seven times its initial length, yet springs back to it’s original length once tension is released.While lycra appears to be a single continuous thread, it is in reality a bundle of tiny filaments.
