Commercial silk kills the silkworm. Conventional silk is made by boiling the intact cocoons and unwinding the single silk strand onto reels. Only a few moths are allowed to emerge to continue the population of silkworms. The rest are killed by being boiled in their cocoons. This is done so the silk fibers are not broken and can be reeled off in a continuous strand. However, the silk can still be spun like other fibers if the moths are allowed to emerge.
Peace Silk or Organic Silk lets the silkworm live out its full life cycle. "Peace silk" is raised and processed differently. The moths are allowed to emerge from their cocoons to live out their full life cycle. The silk is degummed and spun like other fiber, instead of being reeled. The resulting yarn is soft, fluffy, and light like a cloud. This is the best silk for warmth and therapeutic use.
