Lake Constance by Stanton is made with Solution Dyed Royaltron Polypropylene. Solution dying is a process where the yarn is infused with color pigment during the manufacturing process. This creates superior colorfastness characteristics and color retention. Royaltron is resistant to signs of wear due to the long lasting fibers. Inherently hydrophobic fibers do not absorb moisture making spills and stains easy to remove. Additional properties include anti-microbial and anti-static features.
