A Description of Common Carpet Fibers
Nylon
Nylon is the most common of all carpet fibers, and its high durability makes it a popular choice for areas of the home that receive high foot traffic. Resistant to most dirt, mildew and moisture, this fiber is also known for its ease of maintenance and non-allergenic properties.
PET Polyester
This is an excellent fiber choice for the budget conscious. Polyester shares many of nylon’s nonallergenic, moisture and wear resistant properties but lacks the same degree of durability.
Polypropylene
This fiber was first used in carpets designed for use outdoors and in spaces with high levels of moisture and humidity. Color-fastness, resilience, and resistance to water damage, mildew and piling are important benefits of this fiber. Polypropylene fiber is also recognized for a luxurious appearance and outstanding softness.

Made from terephthalic acid and ethylene glycol. Offered primarily as a staple product, although some BCF in being produced. Used in residential and commercial applications. 100% of Mohawk's Staple Polyester is PET Polyester, manufactured from recycled plastic bottles. |
Color clarity Colorfastness Resistant to water-soluble stains. Noted for luxurious "hand". |
Polypropylene (Olefin) |
Fiber-forming substance of any long-chain synthetic polymer composed of at least 85%, by weight, of ethylene, propylene, or other olefin units. Offered primarily as BCF with some staple product available. Primarily sold as solution-dyed or pre-dyed fiber. Can be engineered for outdoor applications. |
Resists fading. Inherently stain resistant. Limited color selection. Generates low levels of static electricity. Chemical, moisture, and stain resistant. Favorably priced. |
