To make SUPPLEX® , the nylon is extruded through the smallest possible holes, creating a fiber that is ultra-fine, lightweight, and flexible. Thousands of these ultra-fine strands are then wrapped together to form the SUPPLEX® fabric. The tiny nano-fibrils enhance the softness of the fabric, giving it the benefit of being as comfortable as cotton, while out-performing cotton by not shrinking, wrinkling, or fading in color. Additionally, SUPPLEX® is still able to hold the durability and strength of nylon.
