The fiber used in a carpet will determine its wearability. The more you know about fiber, the easier it will be to choose the right carpet for your home.
Nylon: Nylon particularly type 6 is the strongest, most durable and most widely used fiber. The soft texture holds its color well, resists most food and beverage stains and many oil-based stains, and is easy to clean.
Wool: Wool carpets are warm and durable, but can be damaged by alkaline cleaning detergents. They're also available in fewer shades because they don't take bright color dyes well.
Polyester: These carpets are reasonably durable, but some are more susceptible to oil-based stains.
Polypropylene: Polypropylene carpets are moisture resistant and are available in a limited selection of colors. They also lack bounce and resiliency in all but the most dense constructions.
