Pop Bottle Carpet
We went to a Parade of Homes in our area and two of the homes had "pop bottle carpet" in them. It was very attractive and we were told that it is extremely durable. Here is a description I found online:
PET POLYESTER:
This is a new type of 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. I will keep adding to this fiber page as more info about PET products reach my attention.
Also, in the Polyester family is its superior cousin PTT. This fiber is known as SMARTSTRAND (trademark) when marketed by Mohawk, but other mills just call it PTT. This fiber is even stronger than PET polyester, and has better colorfastness and cleanability features than PET. PTT is as colorfast as solution dyed nylon. This fiber is extremely soft, and yet behaves better than staple nylon, especially in a shag construction. If you have kids and pets, and are going to be in the home more than 10 years, PTT is a good choice; especially the 3GT Sorona Dupont Polymer offered in some Mohawk carpets. I have not had a comsumer complaint on this fiber in the four years I have been selling it. By the way, PTT is just one step away chemically from 4GT polyester that is used to make tough auto parts.
