Corn Yarn Carpet has stain resistant properties built into the fiber. The durability is also superior to most carpets available today. When comparing different carpet fibers we have found that Purlon (TM) Corn Polymers allow for wear resistance that is superior to a similarly constructed nylon. We have found that it has a performance level of a wool fiber without the problems associated with wool. CornCarpet has many different styles and qualities and so does many other bio-based carpets. We are careful to create only mid to high-quality carpets. So we do not make apartment/ base grade carpets.
