The fibers we choose have a big job to do—work hard, lower our environmental impact and look beautiful for a very long time. So we purchase from leading manufacturers who provide premium, solution dyed fibers with a low modification ratio.
More Than Skin Deep
Solution dying injects fiber with color throughout, not just on the surface. Color lasts longer, resisting most bleaches and other harmful liquids as well as sun exposure. And with the stain resist technology that’s built into the fibers, you’ve got added protection against staining with no need for an additional topical treatment.
Modification ratio estimates a fiber’s performance by how “round” it is. The rounder the fiber, the lower the modification ratio, the better it performs. The fibers we use have a modification ratio of 1.5 - 2.1, whereas mill extruded Type 6 Nylon has a ratio of as much as 4.7.
Passing the Test
We go beyond standard wear testing with our proprietary ART – Appearance Retention Test. ART is the only test of its kind to simulate real world usage for 1 year, 5 years, 10 years or more. We simply won’t release a product that doesn’t pass our rigid ART standards.
Doing More With Less
We get superior performance with the highest available post-consumer and post-industrial recycled content. We’ve partnered with our fiber suppliers to continually reduce the virgin content in the fibers we use. Content for these fibers includes everything from the post-consumer Type 6 and 6,6 Nylon fibers we provide through our ReEntry partners to salvaged commercial fishing nets that Aquafil incorporates into the 100% recycled content Type 6 Nylon we use.
Why use premium fibers?
Interface's premium branded, solution dyed nylons are key to our products' durability and long lasting beauty.
Low vs. Higher Modification Ratio Fiber
To illustrate the superior performance of the fibers we use, we ran a 10 year wet and dry ART test on an Interface product made with fiber that had a modification ratio of less than 2.0, along with a competitive product made with fiber that had a modification ratio of greater than 2.5. See the cross section of each fiber and the before and after images of the length of the fibers. Notice the abrasion and breakdown of the fiber in the competitive product.
