This is a new type of polyester fiber that has this long chemical name: Polyethylene Terephthalate, but still falls in the class of fibers known commonly as polyesters. This PET fiber, however, is “not your daddy’s polyester”. This fiber has natural and permanent stain resistance. PET fiber is stronger than the old polyester and has better abrasion resistance. Unlike the old polyester, the PET product has a higher melting point and is more resistant to abrasion.
The fiber is made from PET chips, some of which come from recycled plastic containers, hence the name “pop bottle carpet”. Recycling does not affect the quality if the fiber, thus this product could be a future fiber that could be recycled over and over.
On a personal note, I had a customer spill hair dye on her 6 month old PET Polyester carpet. Hair dye is on the list of not warranted stains, but this lady got the stain out with a laundry detergent and water. I was impressed.
Many PET carpets are now produced in solution dyed form, and in continuous filament form. This has resulted in a carpet that is even stronger than the old staple versions of the fiber, and in a fiber that holds its twist even better. As a result, PET now accounts for over 50% of the residential carpet market. So if you find a newer PET carpet that has a great twist to the fiber, a face weight of at lease 40 ounces, and continuos filament, then go for it, as you will like the end result. Just keep this and all carpets clean.
