Silk is a protein fiber spun by silkworms and is a renewable resource. Silk is also biodegradable. For these reasons, we consider silk a sustainable fiber. However, chemicals are used to produce conventional silk, so we will always consider organic silk to be a better option.
Because conventional silk production kills the silkworm, animal rights advocates prefer “Peace Silk”, Tussah, Ahimsa silks which allow the moth to evacuate the cocoon before it is boiled to produce silk.
