Compare a polyester carpet with a nylon carpet of the same color, and you will notice the difference: the polyester appears much more vibrant, while the nylon has a more dull or matte finish. Stain Resistance. Perhaps one of the biggest draws of polyester is its inherent stain resistance. Polyester is referred to as a closed-cell fiber, which means that it does not have any open dye sites for stains to adhere to. That is not to say that it is completely stain-proof, of course. However, most of the spots on a polyester carpet that people attribute to staining are more likely due to soiling. Soiling is different from staining. In the case of a stain, a substance has come into contact with the fiber and has embedded itself into the fiber, by attaching to open dye sites within the fiber.
