Nærø textile felt is produced from worn-out workwear, which can no longer be used for clothing or other secondary clothing production. We have developed a method for sorting, where we get clean and pure fractions of textiles, which ensures high quality for the end product. After sorting the fabric is ground and this process transforms the material from woven form to short, manageable fibers. The short fibers are mixed with binders and, if need be, a cradle-to-cradle certified fire retardant. The final part of the production process is felting, which binds the material together into nonwoven acoustic batts.
