WeatherShield HP is manufactured with solution-dye fibers which makes the fabric more fade resistant. Solution-dye isn't really a dye process, the color pigments are mixed into the compound that is extruded as thread. This puts the color all the way through each fiber making it more fade resistant and saves 1,000 gallons of water for every 1,000 yards of fabric produced since they don't surface-dye the fabric. To construct this fabric, pre-finishing chemistries are applied to the solution-dye polyester fabric to prep it for the encapsulation process. Nextec proprietary equipment then applies a viscous patented mixture of silicon-based polymers onto the fabric. Heat and pressure is applied to the polymers, working them inside the fabric and wrapping the individual fade resistant fibers. All but the smallest spaces are filled and the micro holes that remain allow the fabric to breathe so any moisture or heat under the cover can easily escape. Specially designed ovens cure the polymers to a solid state and the fabric is ready to make into covers. No microfibers, no laminates, and no surface coating. "EPIC" by Nextec's encapsulation process delivers all-weather protection, compact packability, easy care, and a soft-to-paint touch without sacrificing breathability. WeatherShield is not waterproof, but if kept clean it will shed most water and helps prevent dust, dirt, bird droppings and tree sap from reaching the vehicle surface. The breathable properties of the fabric assure that any heat, moisture or condensation under the cover can easily escape. This cover is backed by a four-year warranty against fabric flaws and workmanship.
