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.
How LYCRA® is used
LYCRA® is never used alone; it is always combined with another fiber (or fibers), natural or man-made. Fabrics enhanced with LYCRA® retain the appearance of the majority fibre.
The type of fabric and it’s end use determine the amount and type of LYCRA® required to ensure optimum performance and aesthetics. As little as 2 percent LYCRA® is enough to improve a fabric’s movement, drape and shape retention, while fabrics for high-performance garments such as swimwear and active sportwear may contain as much as 20-30 percent LYCRA®. Weaving or knitting techniques, togheter with fabric type and end use, determine whether LYCRA® is used in a bare or covered yarn form.
