Textile shower curtains are water repellent rather than waterproof. The 100% polyester fabric is made water repellent by the addition of an acrylic coating called Proseal. The sides, top and bottom of the curtains are neatly hemmed and the bottom hem includes a weight to ensure that the curtain hangs straight and does not cling to the user when wet. The eyelets are reinforced with white painted rust-resistant metal to give a smart finish. All textile curtains can be machine washed at 40 degrees celsius and pressed with a cool iron. However, they still must not be dry cleaned or tumble dried. Textile curtains are also available with Hygiene 'N' Clean anti-microbial treatment. They can be broadly divided into the following headings: Plain and Printed fabric textiles, Waffle curtains and Voile curtains.
