 　　Secrets Of Silk Production

 

　　Fifteen hundred years ago in China, silk production was a state secret.

 

　　The silk trade was so valuable that anyone who tried to take silkworm eggs or mulberry seeds out of China was put to death. Then in 552 AD, two monks¹ smuggledsilkworm eggs to Constantinople, and silk production spread worldwide. Now that the secret’s out, we can safely talk about how silkworms and humans make luxurious² silk cloth.

 

　　A silkworm actually isn’t a worm at all. It’s a type of caterpillar³ that once existed in the wild, but now only survives in domesticated⁴ form. Silkworms are fussy⁵ eaters, dining only on mulberry leaves. When a silkworm has had its fill, it spins a cocoon⁶ from a single strand⁷ of silk, two to three thousand feet long!

 

　　According to legend, a Chinese empress discovered how to harvest silk when a cocoon fell into her tea. She plucked it from the teacup by the loose end of the silk, then unraveled the whole cocoon. To harvest silk commercially, cocoons⁸ are first steamed to kill the pupae inside. This is because the silkworm would break the silk if it began to emerge as a moth⁹. Next the cocoon is dunked in hot water, rather than tea, to dissolve the sticky coating that binds¹⁰ the silk. Then a machine unwinds the single strand that makes up each cocoon. Twisted together, these strands¹¹ make the fine thread used to weave silk cloth.
