Nylon is the most common and widely used fiber for rugs because of its extreme durability and resistance to wear and abrasions. It's a synthetic fiber that produces little shedding and provides a less expensive option than all-wool rugs.
Less expensive than nylon, polypropylene is a man-made fiber popular for its resistance to stains. Strong and colorfast, it is best used for areas where children and pets play. With a wool-like feel, rugs made with polypropylene offer tremendous value.
Natural fibers, like soft wool, add an element of beauty and luxury to any room. It is a very popular material for higher-end rugs due to its natural ability to repel water and resist crushing. Wool is not only hypoallergenic and ideal for absorbing sound, but it also feels great under your feet.
