Triexta is a third-generation synthetic carpet fibre with permanent stain and odour resistance built into the molecular structure of each strand. Unlike nylon carpets that rely on a topical stain treatment applied to the surface, Triexta’s resistance cannot be washed or worn away over time. It is also generally softer than nylon, which makes it a popular choice for family rooms and bedrooms. Triexta by Redbook is the main brand available through Floorworld stores and offers one of the strongest stain warranty packages in the residential carpet market.
