Question -
Hey Jim,
Do these new "Triexta" carpets clean better than the regular polyesters? The dealers seem to think it's the new miracle carpet fiber!

Answer -
Glad you asked about this new fiber.

Following my comments is a press release you should read & keep a copy.

But first, just why is this press release of importance to you, the carpet cleaner? Simply this: "Triexta", often marketed under the Mohawk brand name "Smartstrand ™", has and is promoted as a "new and better" carpet fiber. While this product is partly made from sustainable resources, and has been claimed to have superior resiliency than the original "PET" polyester fiber, it is important to note that no claims of superior oil resistance are being made for this product.

You should, of course, work as closely as possible with any manufacturer's directions if asked to clean a carpet while its under warranty, but do not be overly enthusiastic about stain resistance claims made about this product.

It is true that "Triexta" has superior WATER BASED stain resistance, and that even stains that contain dyes may be easier to remove, but there is no evidence that this product is any less oil loving than "PET" (polyester). For that reason, you may need to use preconditioning agents designed to break the oil bonding that occurs with such fibers before you can successfully clean this carpet, or any other oil loving carpet such as “PET” (polyester).

Feedback on your experience with this new fiber and how it has responded to professional cleaning is welcome.

A New Carpet Fiber!

The Federal Trade Commission (FTC) has issued a final rule, effective March 26, 2009, that establishes the subclass name triexta as an alternative to the generic name polyester for a subclass of polyester fibers made from poly(trimethylene terephthalate).

The petitioners who sought this designation stated that PTT fiber, while having the same general chemical composition of polyester, has distinctive features of durability, resilience, softness and ability to stretch with recovery that make it significantly more suitable than conventional polyester for carpet and apparel.

The FTC has concluded that each of the four criteria for creating a new generic fiber subclass have been met:


  1. PTT has the same general chemical composition as an established generic fiber category

  2. PTT has distinctive properties that make it suitable for uses for which other fibers under the established generic name would not be suited or would be significantly less well suited

  3. These properties are important to the general public

  4. These properties are the result of a new method of manufacture or PTT's substantially differentiated physical characteristics.
