Synthetic, or human-made carpet fibers have gradually overtaken natural fibers (e.g., wool) to become the leading fabric choices for wall-to-wall carpeting. This didn’t happen by accident; both manufacturers and homeowners prefer synthetic fibers over natural ones in large number because they cost less, they’re stronger and more durable (which allows for longer warranties), and they’re more resistant to stains. Today we’re going to take a look at the four primary types of synthetic carpet fibers found n the residential market today: nylon, polyester, triexta, and olefin. Each has its pros and cons; despite what you might have heard from coworkers, family, friends, or carpet manufacturers, there is no perfect fiber. That said, there’s never been a better time in history to buy a carpet. Let’s dive into which synthetic fibers you’re going to come across if you’re in the market for a synthetic carpet as well as which carpet cleaners and vacuum cleaners we recommend for caring for them.

What are the pros and cons of nylon carpets?

If you've ever admired a synthetic rug (like this one), chances are it was made from nylon.

Nylon is probably the most popular synthetic fiber of all time; it was considered the best carpet fiber for years, and it still is by many. Overall, nylon is very resilient. Nylon-based rugs and carpets regain their “spring” after flattening or compacting, and are typically very durable as a result. The main disadvantage of nylon compared to other synthetic fibers is the fact that you’ll pay more for it per square foot. It’s also less resistant to stains, although nylon carpets will typically always come with stain resistant treatments.

Why choose (or avoid) polyester carpets?

Polyester, which is short for polyethylene terepthalate (PET), is a fiber with a long history in carpeting. In the past it was seen as a lower-quality fiber compared to nylon, simply because polyester isn’t as resilient or strong. However, polyester production has come a long way in the last few decades, and its durability has increased as a result. The primary advantage of polyester over nylon is stain resistance, which is built into the fiber. Polyester carpets and rugs are also more environmentally friendly than nylon because they tend to be made from recycled materials.

What are the advantages and disadvantages of triexta carpets?

If you want environmentally-friendly superstrong carpeting, you want triexta.
If you want environmentally-friendly superstrong carpeting, you want triexta.

Triexta is the new kid on the block in terms of carpet fibers, and it’s making waves in the industry. The US Federal Trade Commission (the FTC) approved triexta as a more human-sounding name referring to polytrimethylene terephthalate, or PTT. In other words, they classified it as a new fiber offshoot of polyester.

Although triexta is a close relative of polyester, it behaves rather differently in a number of ways. The most significant change is that it’s a lot tougher than polyester. Howevet, it’s also a lot softer too, even though the carpet industry has also managed to come out with softer polyester carpets. Triexta carpets are also considered more eco- and allergy-friendly due to their manufacturing processes, which typically involve things like corn glucose instead of petroleum from dead dinosaurs. As a result, there’s a lot less off-gassing and a lot less destruction of the environment with triexta than with pretty much any other kind of synthetic carpet. One of the leading lines of triextra is the SmartStrand from Mohawk.

What do you need to know about olefin carpets?

Broadloom can be beautiful.
Broadloom can be beautiful, whether in wool or olefin.

Olefin is a brand name for polypropylene, and you’ll find it frequently in broadloom styles of carpet (berber, for example), as well as in area rugs, as it looks a lot like wool. Its durability is often less than the other main synthetic fibers. As a result, you’ll mainly see it in looped carpeting styles where there isn’t as much of a need for resiliency as with cut-pile carpets, which are inherently weaker than still-looped carpets. However, because olefin is highly stain resistant as well as fade resistant, you’ll see it frequently used in areas with children, pets, and heavy traffic.
