Types of fiber..


Nylon
This is the most commonly used fiber in carpet today because it is strong, easy to dye, and readily available. There is still no stronger carpet fiber on the market today. If you have any traffic paths at all, I strongly recommend you buy a nylon carpet and forget about those other fibers. There are many makers of fiber, but the leaders are Invista (formerly DuPont), Solutia, BASF, and Honeywell (formerly Allied Chemical). They all profess their nylon to be best. Invista and Solutia(formerly Monsanto) have the most well known brands of nylon with the Stainmaster and Wear Dated types respectively.
Stainmaster nylon and Wear Dated nylon are simply triloble (cross grain magnified picture looks like a clover leaf) fibers with a fluorocarbon added to resist staining.Invista and Solutia have done a super job of marketing to convince you that theirs' is best. Also, their yarn is a type 6.6 nylon and is marketed as being "better" than type 6 nylon. However, recent studies by leading chemical engineers suggest that the differences between the two types have little to do with a carpet's overall performance, and further suggest that carpet construction is more important than fiber. The reason the consumer has to pay about $1.00/sq.yd. more for Stainmaster or Wear Dated than unbranded nylon fiber is that Invista and Solutia spend millions of advertising dollars to convince you their fiber is better. This cost is passed on to the mill, and then to the dealer, and then to you. Invista did help the consumer by breaking their fiber quality into groups. The lowest quality Stainmaster is now StainmasterPlus; then Xtra-Life Stainmaster , with Grand Luxuria Stainmaster as their top of the line. If you really want the ultimate in SOIL hiding from a nylon look for Invista's Antron nylon. This fiber is only available in some residential styles. Your light-weight sparse carpet will not carry the Grand Luxuria label, heck it may not even carry the Stainmaster Label at all. Don't be confused. You can purchase a super tightly twisted, medium dense carpet that is multicolored to help hide traffic and soil, and you will love the way it looks new for years; it just will last even longer if the fiber is nylon.



Olefin or Polypropylene
This is one of the most color fast fibers on the market. It also is one of the most naturally stain resistant. Thus, this fiber is best suited for indoor-outdoor carpet in both loop and grass styles. Olefin is a cheap fiber. It performs well in wear tests if the profile of the pile height is super low. If one adds air to the fiber to give it some bulk (so it feels good), it will not produce a carpet that looks good for longer than six months. This puffed up Olefin will crush! I guarantee it. Also, Olefin has such a low melting point it must have oil added to the fiber in order to survive the tufting process. When the carpet is finished, most American manufacturers do not spend the money to rid the fiber of all the oil. As a result the carpet crushes even quicker.The one exception to this process is a new type of olefin fiber called "Comfortouch" by Shaw Industries. This new fiber is softer to the feel because this olefin fiber is scoured three times during the making. Then the fiber is treated with R2X. The result is a fiber that feels like cotton, resists soil and stains better than any other carpet, and wears extremely well. My advice is to leave olefin to the outdoor market or light traffic indoors unless you are able to find a dealer who carries olefin carpets from Europe, or the new Comfortouch from Shaw. Those of you who have fallen in love with the Berber style of carpet make sure it is not made of polypropylene or olefin with the larger loops.



Wool
If you are looking for your basic commodity carpet, do not expect to find it in wool. Wool makes excellent berber carpet, plush carpet, and frieze carpet. The best quality wool is from New Zealand. Wool naturally resists general soiling, crushing, and most stains. Wool is also naturally resistant to fire. Look for wool carpets made with jute backing (yes like the good old days) as it has a superior tuft bind. The soft look and the rich feel of wool is still unmatched by any man made fiber, and can be more affordable than you think. Wool carpet is indeed a long lasting luxury carpet.
