Early in its development, Orlon was a problematic fiber to spin or dye. However, the ongoing work of DuPont eventually resulted in a material that was a tremendous commercial success, though it has been replaced in recent years by newer synthetic fibers in many applications. Warm and soft, Orlon was a longtime favorite in clothing and its resistance to degradation from sunlight and atmospheric gases also made it well-suited for outdoor items, such as beach umbrellas and awnings. Moreover, many items comprised of Orlon could be machine washed and dried, a distinct advantage over wool, a material that DuPont hoped the fiber would eventually supplant in the world market.
