Cotton Alternatives Soy for shirts

Soy -   Made from byproducts of soybean crops, soy fibers can be spun into yarn to make everything from T-shirts to socks to poloshirts and even ladies shirts. In addition to having a soft, smooth hand, soy-fiber products contain natural anti-bacterial agents and the same moisture-absorption properties as cotton, but with better moisture transmission for drier, more comfortable shirts, poloshirts and ladies shirts.  In addition, unlike cotton, it won't shrink under normal washing conditions.
