A concern for some of our customers is whether the DWR (Durable Water Repellent) treatment on our quilt fabric is PFC free. Traditional DWR treatments used C8 fluorocarbons, which have been found to be toxic to both the environment and humans, and take a very long time to break down. The DWR on our fabrics does not use C8 fluorocarbons. The Pertex fabrics we use feature a DWR treatment which uses a shorter chain C6 fluorocarbon, which breaks down more quickly than C8, and has not been shown to have negative health effects.
