Silkworms make silk by spewing a substance called fibroin through small holes in their jaws called spinnerets. The spewed-out substance consists of digested leaves and protein produced by the worm. The silkworm produces up to 1200 silken threads within a 72 hour time period, creating a soft, silver cocoon.
How much silk can you get from a silkworm?
It is interesting to note that one ounce of silkworm eggs contains 40,000 eggs (1,500 eggs per gram). These worms will eat 3,500 pounds (1500 kilograms) of mulberry leaves, and will spin cocoons which will produce 18 pounds (8 kilograms) of silk thread. It takes 1700 to 2000 cocoons to make one silk dress!
