Acrylic fabric is a strong, durable material woven from synthetic acrylic fiber. The fiber is made by creating a synthetic polymer called polyacrylonitrile, which is then spun into a long, solid acrylic fiber.
Solution dyeing is a specialized method of dyeing synthetic fabrics that adds the color at the beginning of the manufacturing process. Instead of making a colorless material and soaking it in the dye, color pigments are added to the liquid acrylic material before it is spun into a richly colored fiber. This means the color is a built-in part of solution-dyed fabrics.
