Nylon, Polyester, & Polypropylene Rugs: Everything You Need To Know

Published May 2024 | Updated August 2025

Commercial and household project managers know that with any remodel or design project, specifying with the right material in the beginning saves time and headaches down the road. In this post, you will learn about the pros and cons of synthetic carpet materials like nylon, polyester and polypropylene so you can make the best choice for your application.

Common Materials for Synthetic Rugs

The majority of synthetic rugs and carpet are made from nylon, polyester, or polypropylene: three materials known for their durability, cleanability, and versatility. These same materials comprise the majority of commercially rated carpet in the market today. 

Nylon

What is it?

Nylon is a synthetic fiber or yarn used in both residential and commercial carpets. It is strong, abrasion resistant, and resilient, and therefore most commercial carpet face fibers (the top pile) are nylon.

Also Known As

Polyamide, PA6 (polyamide 6), Nylon 6, Nylon 6,6 and ECONYL®. 

• Nylon is a synthetic thermoplastic comprised of a polymer chain with recurring amide groups, hence “polyamide.”
• The numbers refer to the different carbon structures—nylon 6’s molecular structure has one monomer and 6,6 has two monomers. Although it is debated, there is little difference in performance between them.
• ECONYL® is a regenerated virgin-quality nylon product made from recovered and repurposed materials. The SynSisal® collection is crafted from ECONYL® yarns, which can be recycled and regenerated into nylon fiber for reuse. A cradle-to-cradle cycle with positive environmental impacts.

Pros

• Contract Grade: Nylon carpet is widely available with contract ratings for commercial settings.
• Cleanable: Unlike natural fibers, a nylon carpet is cleanable and resists stains.
• Durable & Resilient: Tough nylon fibers bounce back after compression.
• Abrasion Resistant: High quality nylon is tough and handles heavy foot traffic and regular cleaning.
• Colorfastness: Thanks to solution-dyed yarns, colors stay true.
• Hypoallergenic: Nylon is moisture and mildew resistant.
• Wide range of styles and qualities available.

Cons

• Cost, more expensive than a polyester and polypropylene carpet of comparable quality.
• Static electricity can build up unless treated with anti-static material.
• Not as soft as polyester, although technological advances are improving the feel of all synthetic carpet fibers.
• Not inherently stain-resistant unless treated; nylon is very absorbent but can be manufactured with a stain-resistant treatment.

Polyester

What is it?

A synthetic fiber family used in the manufacture of both residential and commercial carpets. Sometimes made from recycled materials, polyester fibers are soft and hold vibrant color well.

Also Known As

PET, rPET, poly silk

• PET, or polyethylene terephthalate, is a polyester fiber made from recycled plastics (e.g., water bottles).
• rPET is specifically designated when the PET fibers are 100% made from recycled plastics.
• Poly silk is a manmade polyester fiber with a soft texture and a silk-like sheen. It does not absorb moisture and is mold and mildew-resistant.

Pros

• Contract Grade: Polyester carpets are becoming increasingly more durable and appropriate for busy commercial settings.
• Colorfastness: Excellent color clarity and retention.
• Stain-resistance: Resists water soluble stains.
• Outdoor friendly: Some recycled PET polyesters are approved for outdoor use. Check specifications to be sure that the backing and/or the border (on a rug) is appropriate for outdoor-use.
• Feel: Softer touch than nylon and polypropylene, although technological advances are improving the feel of all synthetic carpet fibers.
• Affordable
• Wide range of styles and qualities available.

Cons

• Not all polyester carpets are rated for heavy commercial use.
• Less resilient and fibers will compress over time.
• Not as durable as nylon and may have to be replaced more frequently in busy areas.

Polypropylene

What is it?

A synthetic fiber used in the manufacture of both residential and commercial carpets. It is a long chain polymer composed of ethylene, propylene or other olefin units, and accounts for about a third of carpet face fibers in commercial carpeting

Also Known As

PP, Olefin

• PP is shorthand for polypropylene 
• Olefin is the generic name for polypropylene

Pros

• Contract Grade: Not all polypropylene carpets are contract grade—it depends on the backing and the quality of the fibers. If the polypropylene carpet does not have a backing, then it is not contract grade. Unbacked polypropylene carpets are particularly great for outdoor residential settings. A backed polypropylene from the Terasa collection is commercially rated as well as outdoor friendly.
• UV-resistance: Yarns are colorfast and resist fading, even in sunlight.
• Outdoor friendly: Polypropylenes are great for outdoor use. Check specifications to be sure that the backing and/or the border (on a rug) is appropriate for outdoor-use.
• Anti-static: Generates low levels of static electricity.
• Favorably priced
• Hydrophobic: Polypropylene is impervious to moisture, making it mold, mildew, moisture and stain resistant.
• Solution-dyed yarns mean polypropylene is very stain-resistant and fade-resistant.
• Affordable
• Wide range of styles and qualities available.

Cons

• Not all polypropylene carpets are rated for commercial use.
• Not as durable as nylon and polyester. However, construction plays a major role in longevity—a tightly woven, flat weave polypropylene carpet like Brisbane is very durable compared to a loose textured polypropylene carpet. 
• Oleophilic: not soil resistant and attracts oil-based dirt.
• Not as abrasion resistant as nylon.

Sustainable Synthetic Fibers: ECONYL® & rPET

The desire for cradle-to-cradle opportunities in the carpet industry is leading to exciting innovations and developments in the manufacture, production, and life cycle of flooring materials. Many manufacturers today regenerate recycled plastic bottles, fishing nets, and other post consumer waste (including nylon from carpets!) into cutting edge fibers like ECONYL® or recycled PET yarns. Instead of virgin synthetic fibers made from petroleum, today’s innovative synthetic fibers mean a smaller carbon footprint.

As with all new and emerging technologies, the product cost can be a barrier. But as the industry moves toward greener carpet production, costs will decrease while the benefits for all increase.

If a natural material is still your preference, there are some contract-grade options. Our All Natural Commercial page highlights wools from the Pure Wool and Jacaranda collections as well as stain-resistant sisal rugs and Sisal Tiles.

Nylon vs. Polyester vs. Polypropylene Comparison Chart

Always check the specifications for the carpet or rug you are considering. Synthetic fibers are manufactured to meet different needs and end use applications—one nylon carpet might have UV-resistant yarns but only a residential use rating, while another may have both UV-resistant yarns and a contract grade rating.

The comparison table below primarily references high quality, contract grade versions of these fiber types and assumes the yarns are solution-dyed, UV-resistant, and have some level of stain-resistant treatment.

Common Characteristics For Synthetic Rugs

Tufted or woven, low pile or high pile—these are just a few examples of common rug or carpet attributes. The construction or final pile height of a carpet often dictates its use—a hand-loomed carpet will not hold up well in a busy, commercial space and a carpet with a plush, high pile is best for residential settings. Let’s go over a few carpet basics:

Construction & Pile

Tufted

Tufting is the fastest method of carpet production and the most common. A tufting machine is like a giant sewing machine, with hundreds of needles stitching or punching the pile yarn (or face yarn) through a primary backing. A tufted carpet can have a variety of finished pile styles, like loop, cut and loop, multilevel loop, or plush. 

Woven

A woven carpet is made on a loom, either machine or manually operated, and does not have knots. Instead, the stability of the weave depends on the interlacing warp and weft yarns. The pile yarns or face yarns and backing yarns are woven simultaneously. A woven carpet can have loops, cut piles, or a flat weave.

Pile Height

Pile height refers to how tall the carpet fiber or face yarns are and is an important consideration in commercial settings or residential settings. For example, a higher or more plush pile is great for a luxurious vibe, but may not comply with ADA regulations or may block clearance in a doorway. In general, contract environments require low-pile carpets that are easy to navigate over and keep clean.

High Pile vs. Low Pile

No matter the construction, all carpets have a pile height. A low or short pile carpet has very short fibers or tufted low level loops. High pile carpets have larger loops, multi-level loops, or cut fibers that are long for a dense cushion. Since pile or face yarns represent the majority of the material cost of carpet, be sure you are specifying the right height for your project. The higher the pile, the more difficult it can be to clean.

What is a flat weave rug or carpet?

A flat weave rug is a woven rug with the interlacing warp and weft yarns forming the dimensionality of the weave. The yarns are pulled tight and low, creating a flat surface. Flat weaves have a low pile height and do not have loops.

Some flat weave rugs do not have a backing. For example, many flat woven polypropylene rugs are not backed and are ideal for residential outdoor use. Natural flatweave rugs like sisal or seagrass have a latex or jute backing. Lastly, many synthetic flat weave rugs have a durable backing and a tight, flat surface, making them a great choice for busy households or commercial settings with heavy traffic.

A Word About Carpet Padding

The under pad or underlayment for any wall-to-wall carpet installation or area rug makes a positive impact on comfort level, sound absorption, and the overall lifespan of your floor covering. 

• For area rugs, a carpet pad stabilizes the rug in place while adding a cushioned layer. Keep in mind the thickness of the pad—the thicker it is, the more likely it creates a tripping hazard.
• For wall-to-wall installations, rely on the expertise of your professional carpet installer.
• When installing flat weave carpeting, the underlayment or carpet padding should be dense and not too cushy or thick which can compromise seams.

Final Words

In conclusion, synthetic fibers like nylon, polyester, and polypropylene are great options for contract settings or if you are looking for a cleanable, durable floor covering. Nylon reigns supreme in regards to overall performance: heavy contract ratings, high resiliency, cleanability, and longevity. But a polyester or polypropylene carpet carries many of the same credentials, like contract ratings, durability, and cleanability, potentially at a lower price point. And with the advent of regenerated yarns, a greener story is possible for all synthetic rugs.
