Which Silk Is Softest
Silk produced by “cultivated” silkworms grown in a controlled environment is the finest and softest silk. The worms are fed a diet of mulberry leaves until they begin spinning cocoons. Once they complete their cocoons, the cocoons are soaked in hot water then unraveled, producing filaments that can be up to a mile long in size. Process the raw silk to remove the sericin – the natural “gum” that protects the fibers.
