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.
