A feature from American Fabrics no. 44 (Fall 1958) telling the story of Zefran, a new acrylic alloy fiber introduced by Dow Chemical Co. It covers Dow's history and research philosophy, the nine-year development of the fiber, its production at the Williamsburg, Virginia plant, pilot-plant testing at Pittsburg, California, and its claimed advantages in dyeability, pilling resistance and hand. Photographs show laboratory work, fiber processing, and fabrics blending Zefran with wool and cotton from several mills.
