09/03/1996 · The practical and economic potential of generating artificial spider silk sings a siren's song to biotechnologists. Globally, as much as 60 percent of the threads used to weave clothing come from natural fibers, including cotton, wool, and silk. "We're talking about billions of dollars," says Elion. "This is a major market."
