Characteristics and Saran Fiber Uses — Saran fibers wear well and resist common chemicals, sunlight, staining, fading, mildew and the weather. Fabrics made from Saran fibers can be easily washed with soap and water. They are non-flammable. Saran monofilaments are comparatively stiff and they soften at low temperatures. The fiber is heavy compared with most apparel fibers. Saran fibers are used for upholstery in public conveyances, deck chairs, garden furniture, etc. The weight of Saran fibers is too great for wide use as a general textile material.
