Polyester offers exceptional softness and color clarity, and is also naturally stain and fade resistant. Although polyester is not as versatile as nylon, our carpets made of polyester fiber perform very well.
Unlike other fiber types, polypropylene will not absorb water, so it is solution-dyed. Solution dyeing is a process in which color is actually built into the fiber when it is formed making the color an inherent part that cannot be removed from the fiber. This means the color will not fade, even when exposed to intense sunlight, bleaches, atmospheric contaminants, or other harsh chemicals or elements.
Polypropylene is normally used in loop pile construction in which there is less need for resiliency because it is not as strong as other fibers.
PTT (Polytrimethylene Terephthalate) features good resiliency and excellent inherent stain resistance. Recently, some manufacturers have begun applying a topical treatment to PTT carpets. While adequate for staining, PTT still attracts dry and oily soil substances, leading to premature wear in high traffic areas. For this reason, many oil-based stains are extremely difficult to remove.
