Soy cloth uses the byproducts of soybean oil, tofu and soy milk for production.  Manufacturing is done through a process called wet-spinning. In wet-spinning the protein liquids are forced through a device resembling a showerhead, called a spinneret, to make liquid soy.   Next, the liquid soy is solidified to make soybean fiber.   The final product,  the fiber is then used to create sustainable clothing.  The remaining raw material, bean dregs, after having their protein extracted, can be used as fodder or fertilizer.

All auxiliaries used in production of soybean fiber are of a harmless nature, and they are recyclable making the production process a closed end process.

Soy is durable and strong - soy fiber's breaking strength is about 3 times that of wool's and rivals wool for its warmth retention. 

Best of all unlike Wool, Soy is buttery soft to the touch and (Soybean fiber is being touted as "vegetable cashmere"!) easy to care for (no dry cleaning necessary).
