Outdoor Fabric Source primarily uses Sunbrella solution-dyed acrylic fabrics because they are designed for easy maintenance and many years of use. Solution-dying is the process of adding color to acrylic fibers during manufacturing while they are in a liquid state. This characteristic of acrylic fabrics is the key to locking in color, easy cleaning and long life. Acrylic fabric offers incredible resistance to stains, weather and wear in any application. Awning grade acrylic fabric carries a 10-year warranty against loss of color and strength. Furniture grade acrylic fabric carries a 5-year warranty against loss of color and strength. Our Throw Pillows made with Sunbrella fabric will resist water, staining and mildewing. Sunbrella offers a wide variety of colors from Sunbrella solids, Sunbrella stripes, Sunbrella jacquards and a full line of Sunbrella custom order fabrics. Let us make your throw pillows with Sunbrella solution-dyed acrylic and you will enjoy low-maintenance, fade-free pillows for many years in your favorite indoor or outdoor setting.
