There are many different contents for indoor outdoor upholstery fabrics. Acrylic fabric and Olefin fabric are the most common. Dralon fabric is new and coated with Teflon, for added water, U.V. and stain resistance. Fabrics dry within minutes. Dralon outdoor upholstery fabric is more suitable for application that might be exposed to rain.
For outdoor furniture cushions, you can hose down with a suitable fabric cleaner spray product.
This fabric is rated to the highest water resistance. We tested it to see how it performs by making a little pouch and pouring water in to the pouch. We tried to make the water pass through the fabric by rubbing it between our fingers and it stayed dry. Then we poured the water out. The remaining small amount water pooled on the outside of the fabric.
If you want good waterproofing you also need to make sure to seal the seams. There are various products available for this, iron on, or in a tube. You could probably also use fabric glue.
Do keep in mind that you should avoid getting foam filled cushions wet. If you do use foam, there are thin plastic films available which you can cover the foam with. Some outdoor cushions are filled with spun materials which dry very fast after rain.
