Nylon is the most popular fibre in all carpet. This fibre is in approximately ninety percent of residential carpet and sixty-five percent of other carpet. It is durable and static free and resists staining and mildew. The fibre is dyed after production, making it colourfast. Nylon fibres can be either spun or continuous and the fibre height is maintained through wear, making it a good choice for all traffic areas.
Polyester fibre is durable, luxurious, easy to clean, and resistant to water soluble stains. It does not hold the fibre height as well as other fibres. Polyester carpet is less expensive than nylon.
An average of ninety-seven percent of all carpet is made of synthetic fibres as they are more resistant to stains and much less expensive. However, natural fibres tend to resist crushing from traffic better than synthetic fibres.
Olefin is a colorfast fibre created by the mixing of the fibres with dyes during production. It is a strong fibre resisting moisture and mildew and is easy to clean. Olefin is a great fibre in loop carpets such as berber and indoor/outdoor carpet, however, it can crush depending on the pile. Olefin is the most inexpensive fibre.
Blends are made from nylon and olefin. The stains will often stand out as the different types of fibres resist stains differently.
Acrylic fibre is an artificial fibre providing the look and feel of wool. It resists moisture, mildew, fading, crushing, staining, sun damage, and static electricity, however, it is not durable enough for high traffic areas.
Wool is luxurious, strong, stain resistant and maintains its fibre height. Although it is expensive, wool fibre has its weaknesses as it can maintain static and moisture, and it tends to fray.
Some carpet is made from recycled plastics. This carpet is durable, water resistant, static resistant and eco-friendly.
