  • High quality soybean fibre is now made commercially from "okara" (soy pulp), a by-product of tofu production. Soy pulp is the insoluble part of soybean that remains when pureed soybeans are filtered in the production of soy milk. It is high in fibre and contains protein.
  • Companies that make soy yarn usually use byproducts of food manufacturing that would normally be discarded, putting the waste through an extrusion and wet spinning process to create fibers that can be spun into yarn
  • soybean fiber is manufactured using new, cutting edge bioengineering technologies. It is produced by extracting proteins from the residual oils of soybean cake - a liquid "batter" is created and cooked, then the fiber is produced by wet-spinning and stabilized by acetylating, and is then cut into short staples after curling and thermoforming.
  • Wet-spun soy fibers were successfully produced in 4% HCl baths containing various inorganic salts.
  • For extrusion, the soy protein was equilibrated with 40% of water and 15% of glycerol for 24 hours at room temperature before extrusion at 96°C at 20 rpm
