The four basic carpet fibers are Nylon, PTT, Polyester and Polypropylene used to manufacture today’s carpets.
Nylon is the most widely used carpet fiber and is available in both loop pile as well as cut pile styles.
Polyester or PET fibers are not as versatile as nylon fiber but perform very well. It is a natural stain and fade resistant, and provide luxurious color clarity as well as softness to the carpet.
PTT fibers boast good resilience and excellent stain resistance, but they are not preferred in high-traffic areas.
Polypropylene or olefin fibers do not absorb water quickly, so the color is actually built into its fiber when it’s made; thus, its color will not fade with time.
