Types of carpet

Plush:  This is what most people think of first when they think of carpet. It’s composed of twisted fibers of various densities that stand straight up and are cut at the top at a uniform height. This type of carpet provides a very soft feel.
Berber:  This type of carpet is composed of fiber loops of either uniform height or various heights. The fibers can also be a uniform color, but more frequently consist of multiple colors. This type of carpet is excellent in high traffic areas and heavy use rooms.
Cut and Loop:  This type of carpet consists of both cut fibers as well as looped fibers to create a pattern in otherwise monochromatic fibers.
Frieze:  This type of carpet consists of twisted fibers like plush carpet, but the fibers are usually longer and less densely packed together which results in a more informal look.

Characteristics of Different Carpet Fibers

(from Mohawk.com)

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, this fiber is also known for its ease of maintenance.

  • Durable, resilient
  • Abrasion-resistant
  • Versatile in coloration possibilities
  • Favorably priced
  • Must be treated to be stain- and soil-resistant
  • First used in carpet in 1959
  • Commonly used in residential and commercial applications
  • Accounts for 65% of all face fibers in carpet

PET Polyester

This is an excellent fiber choice for the budget-conscious. Polyester shares many of nylon’s wear-resistant properties, but lacks the same degree of durability.

  • Color clarity
  • Colorfastness
  • Resistant to water-soluble stains
  • Noted for luxurious "hand"
  • Offered primarily as a staple product, although some BCF is being produced
  • 100% of Mohawk's Staple Polyester is manufactured from recycled plastic bottles

Triexta PTT

A completely new form of carpeting where fibers are extruded from a new generation of polymer, giving the carpet exceptional durability along with built-in stain-resistance, color clarity, colorfastness, a luxurious softness and ease of maintenance.

  • Permanent, built-in stain protection
  • Wear-resistant
  • Ease of maintenance
  • Luxurious softness
  • Quick-drying
  • Currently used in residential applications and as BCF

Olefin or Polypropylene

This fiber was first used in carpets designed for the outdoors and in spaces with high levels of moisture and humidity. Color-fastness, resilience and piling are important benefits of this fiber. Polypropylene fiber is also recognized for a luxurious appearance and outstanding softness.

  • Resists fading
  • Inherently stain-resistant
  • Limited color selection
  • Generates low levels of static electricity
  • Chemical-, moisture- and stain-resistant
  • Favorably priced
