Is 100% (Sunbrella®, Outdura®, CUSA Standards) acrylic waterproof?
100% acrylic brands like Sunbrella®, Outdura®, CUSA Standards is not waterproof, but it is water-repellent. Over time, normal wear, usage and cleaning will reduce the effectiveness of the water-repellent finish that we apply during manufacture. So, if water-repellency becomes an issue after repeated normal use and cleaning, a specialty product may be used to retreat your fabric. Water-repellency treatments are available for purchase
Will 100% Acrylic fabrics mildew? If kept clean, fabrics will not mildew. Unlike natural fibers, the characteristics of acrylic fibers will not support the growth of mildew. However, mildew can and will grow on any surface that is dirty, so we recommend keeping your fabric clean.
How often should 100% Acrylic fabric be cleaned? 100% Acrylic fabric should be cleaned regularly to prevent excessive dirt from accumulating. Simply brush off any loose dirt and rinse with lukewarm water. To clean, use a solution of lukewarm water (not exceeding 100°F) and a mild natural soap such as Lux™ or Ivory™. Rinse thoroughly to remove excess soap.
Don't all solution-dyed fabrics do what 100% Acrylic does?
Absolutely not, so make sure you purchase 100% solution-dyed acrylic fabrics. There are other fabrics on the market today that are made from synthetic, solution-dyed fibers that have different names and make similar claims. If they are not solution-dyed acrylic, they will not perform, last or retain color as well as a solution-dyed acrylic.
Special yarns made from solution-dyed acrylic in which the pigment is added while the fiber still is in solution. With this method, the color permeates the fiber so it can't rub off or wash away. Stabilizers are also added in the same way to minimize the effects of the sun, to help the fabric maintain strength over time, and to inhibit rot.
