Avra™’s ultra-thin polyester fibers are extruded and held together by a proprietary removable polymer. These bicomponent fibers can be knit or woven into fabrics on conventional equipment. Once the fabric is made, our removable polymer washes away in hot water, resulting in ribbon-like fibers that are smaller than traditional polyester fibers. The result is a distinctly silky fabric that keeps you drier and more comfortable than ever before.
