Nylon Carpet Fiber
Nylon is the strongest fiber of all the carpets. It has excellent resistance to abrasion, insects, molding, mildew, rot, and many chemicals. It is also easy to maintain, and dye, while upholding its color admirably.
With all of these advantages, nylon makes quite a formidable carpet. Thus, it is the main choice for residential use, accounting for 9 of 10 homes. With such a large hand in the residential carpet business, it would be expected that nylon carpet holds up well in traffic, hides soil, and is available in brilliant colors. Which indeed it does all very well. Nylon carpet is priced averagely, not quite as expensive as wool, but more expensive than polypropylene, and polyester.
Nylon does have its disadvantages. For example, nylon carpet is quite susceptible to stains. Nevertheless, manufacturers have developed methods for increasing stain resistance. One method, adding acid dye stain blocker to the carpet, greatly increases its stain resistance. The longevity of nylon carpet depends on the quality you buy.
Midlevel and high-end carpet can last up to 12 to 15 years. However, it does come at a cost. Prices range anywhere from 25 to 50 dollars per square yard. On the other hand, you can buy it quite cheap if your willing to have a lower grade of quality. At 8 dollars per square yard, you will get you basic nylon carpet. Then again, it will lose its color brightness and fade at a much quicker pace. It will also tend to lose its bounce, and relax. However, this is the case with any low-end carpet.
