Polyester Carpet Fibers June 17, 2010

There is great confusion these days about polyester fiber for carpets. When you talk about polyester carpet, do you mean just plain polyester, PET or PTT? Most of today’s polyester carpets are made from PET fibers, which are manufactured primarily from used plastic soda bottles. PET is an improved fiber over the older, original polyester, but it still comes with some of the performance baggage about which you may have heard stories.
The main positives about PET carpets are that when new, they have a great “hand,” which means a particularly soft and luxurious feel. Probably the greatest lure of PET carpets is the price, which is generally inexpensive. Another selling point is the colorfastness and resistance to water-based staining agents. The biggest complaints about this carpet are its propensity to crush and mat quickly – and that oil-based stains are at best difficult – and at worst, impossible to remove.
PTT polyester is a relatively new introduction into the fiber market (by DuPont in 2000) and sold under the trade name Sorona. It has some unique characteristics, like 37% renewable resource content (corn-based) and reports of advanced stain and wear capabilities over older generations of polyester. In fact, because of its unusual performance characteristics in carpet construction, the FTC granted in March, 2009, a new generic carpet fiber name and classification, Triexta. Smartstrand carpets from Mohawk are manufactured from this fiber.
Early reports from both DuPont and Mohawk indicate that carpets made from this fiber will perform to the expectations of nylon, and will also retain the soft feel and stain-resistance of polyester.
