Today's man-made fibers, or synthetic fibers, provide excellent resistance to abrasive wear, crushing and matting, while allowing innovative styling flexibility. Karastan uses premium Eversoft nylon to make many of its synthetic carpets. In addition, we partner with DuPont to create new generations of carpet fibers, like Karastan's SmartStrand<sup>TM</sup> with DuPont<sup>TM</sup> Sorona<img src="http://dev.mohawkind.com/karastan-com/jtip/images/regsymbol.jpg"> polymers.
