PET polyerster VS. Nylon, and the winner is?

 The Big question from consumers is the proformance between Polyester carpeting fiber and a nylon carpeting fiber. In one of my earlier posts I gave a few questions that should be answerd prior to making the decision between the two.
 Basicaly the question becomes stains versus wear.
Nylons is a man made fibor, it has the ability to hold up to heavier traffic more so than polyester. The reason being is the Twist of each strand can be heatset at a higher temperature. Meaning it will keep it's twist and appearance longer. So if heavy traffic is your concern, than a nylon is suggested. Now a "branded" fiber like "Stainmaster" Or "Weardated" uses an advanced technology for both stains and durability.
 I am what you call "old school" and trust a branded nylon over PET polyester.
I you are into the "Green" products than, PET poyester is for you, it is recycled plastic 2 liter bottles and ketchup botttles. Now you know how difficult it is to stain a empty bottle of soda so you can understand why your new PET carpet will be hard to stain.
 A few side notes; BCF stands for bulk continuous filiment. This, in simple terms, stands for less fuzzing and more durability ,even if it is polyester.
 Solution dyed; this means the fibor was made the color it is. Most nylon is made white and has, what the the industry calls "dye sites". The dye sites are filled with dye so the carpet can hold its color, but after it is dyed, the nylon needs a stain resistant coating, like Scothguard, Dupont's Stainmaster. Or Solutia's Wear Dated . Most polyester carpets are solution deyed. Solution dyed products are naturaly more stain resistant.
 Quick over view.
1) Polyester is very stain resistant.
2) Nylon is  the most durable fibor. Besides of course wool and Sisal. that will be for another day.
3) A branded nylon gives you the best of both worlds, durability and stain resistant.
4) BCF. An added feature, less fuzzing and adds durability. Two types BCF and Staple( Short pieces of fiber hight air pressure twisted together)which has the tendency to loose fiber and cause fuzzing.
5) Solution dyed, The best for stain resistance.
