The Story of silk (Cont’d1)

Over the years, the Chinese were able to breed a species of silk moth that is blind and unable to fly. Each lays 500 or more eggs in a few days and then dies. After hatching, the baby worms are fed on freshly chopped mulberry leaves day and night for about a month until they become fat. Each then spins a cocoon around itself, and this is where the silk comes from. Every cocoon is made of a filament about 800 meters (875 yards) long.
