To determine what type of carpet you have, look for the manufacturer's label or tag. This should be located on the back side of the carpet near one of its edges. The label will indicate whether your carpet is made from wool, nylon, polyester, olefin or a blend of these materials. Additionally, it may also provide information about any special treatments that were applied to your particular pile type such as stain-resistant finishes and flame retardants. If there is no label present then you can use a few simple tests to identify which material your carpet is made from: wool carpets tend to be more resilient and springy while synthetic carpets are usually softer and less durable; nylon carpets are often shinier than other types; polyester has a duller finish; and olefin fibers feel like cotton when touched.
