Because it made the paper. This paper was an order of magnitude more expensive than bamboo, but kept much longer. Silkworms eat only mulberry leaves white.

Each butterfly lives only a few days, so it is very important to quickly find a partner . for fertilization silkworm cocoons come in different colors: green, orange, purple – but for the production of silk needed only white. Selected cocoons are immersed in boiling water. This is done to kill the caterpillar inside without damaging the silk thread. The silk thread is thinner than a human hair eight times. At the same time it is very strong and durable. To make one silk dress, needed 2,000 such cocoons, and this – about 70 . kg of leaves or two mulberry silk cocoons come in different shapes: oblong, oval, with jumpers.
