Carpet Fiber Facts

All carpet starts with a fiber. Five basic types of fiber are used in the manufacturing of carpet. Each of them has their own strengths and benefits. You must decide what’s important to you and your decision will be easy!

The five basic types of carpet fibers are: nylon, polypropylene, polyester, polymer and wool. There are also fibers known as Advanced Generation Nylon.

We offer all the latest carpet fibers, styles and colors from the leading carpet manufacturers.

Nylon has been around since the 1960’s and is the most popular carpet fiber.  Nylon is preferred because of its strength, exceptional resilience and texture retention.  Additionally, nylon carpet fiber is soft yet strong, shows color brilliantly, and cleans well. Advanced generation nylons offer the latest in fiber technology and a built-in ability to conceal and resist soil and stains.

Polypropylene (Olefin)

The use of polypropylene in carpet has grown dramatically over the past ten years due to the popularity of Berber style loop carpets. Polypropylene is extremely resistant to stains, fading, and moisture. Polypropylene, a value-oriented fiber, is also notably colorfast because it is solution dyed, which means the color is added during the fiber production and not dyed later. Because it’s so resistant to moisture and mildew, it’s generally a good choice for both outdoor and indoor areas including playrooms, kitchens and dens. However, since it is not as resilient as other fibers, polypropylene is normally used in loop pile applications, where there is less need for superior resiliency.

Polyester (PET)

Appreciated for its versatility, polyester's popularity continues to grow. Polyester offers exceptional softness, making it ideal for thick, cut pile styles. Polyester is also naturally and permanently stain and fade resistant. It has excellent color clarity, color retention, strength, and abrasion resistance. Carpets made from polyester are easily cleaned and they resist water soluble stains. Polyester is a good choice for low to medium traffic settings and typically represents a good value.


Wool was the original fiber for carpet. It’s the only natural fiber and is the most durable. Wool is a tough fiber that can take a beating without losing its strength. Dust, dirt, and oil-based stains come out easily because wool naturally releases the soil rather than absorbing it. In a high traffic room, it stays resilient and bounces back. It’s also environmentally friendly because it comes from a renewable resource. Because it is the most expensive carpet fiber, wool is generally used only in luxury carpets and area rugs.


Carpet can be manufactured with a renewably sourced polymer that is composed, in part, from actual corn--the same kind you grow in your garden.  Using less energy to produce, almost 37% of DuPont Sorona™ is made from renewable resources instead of more limited petroleum ingredients.

Production of seven square yards of 40-ounce SmartStrand™ with DuPont Sorona™ carpet saves enough energy to equal one gallon of gasoline. Production of SmartStrand™ with DuPont Sorona™ emits 63% less greenhouse gas.Sorona™ carpet is tough, resilient, and able to withstand the rigors of household action as well as being soft and plush underfoot and to the touch.
