Interface’s proprietary stain resist technology - Protekt2™ - is built into our carpet fiber, so a topical stain resist treatment is not necessary. Instead of coating the surface of the yarn, we changed the formulation of the nylon we use to permanently increase its stain resistance properties.
We conducted stain tests on our products and compared them to products with a topical treatment. The results?
Our uncoated fibers performed just as well as the treated ones, allowing us to completely remove PFCs and PFASs from our products. By doing this, we have also eliminated any risk of fluorinated chemicals wearing off our carpet yarn, getting into dust in buildings and then persisting in the environment for hundreds of thousands of years. With Protekt2, you get permanent stain resistance, not permanent pollution.
