Nylon carpet has some great things going for it: it is strongly resistant to insects, mold, mildew, rot, stains, and abrasions. Nylon typically maintains its fiber height (i.e., it doesn’t flatten from traffic and weight), it’s easy to maintain and it holds its color very well. Due to these positives, nylon is suitable for high-traffic areas. Nylon is moderately priced, so it is within many people’s budgets. It isn’t quite as expensive as wool, but it’s more expensive than polyester and polypropylene.
Polyester is synthetic carpet fiber that is easy to clean and quite durable. Polyester carpet is often very luxurious and soft, but it may not be well suited to high traffic applications. Overall polyester is able to be crafted into carpets of vibrant colors with fibers that are quite resistant to water soluble stains. Polyester carpet is a soft, budget-friendly choice.
