Nylon is the most frequently used fiber in carpeting today because it is strong, easy to dye, and readily available. There is still no stronger carpet fiber on the market today. Nylon was introduced in 1938 by Dupont and started our modern era of synthetic fibers. As a carpeting material, Nylon has undergone several modifications though the years to reach the quality we have today. There are many makers of fiber, but the leaders are DuPont, Solutia, BASF, and Honeywell. DuPont and Solutia have the most well known brands of Nylon with the Stainmaster and Wear Dated types, respectively. If you have any traffic paths at all, we strongly recommend you buy a Nylon carpet and forget about those other fibers.
