The latest research on silkworms is wonderful news on the fashion front, opening up the possibility for new textiles and more efficient manufacturing methods. But for the silkworms, it also sounds kind of creepy in a science fiction nightmare way.
First, a little background. Humans have had a long and rewarding relationship with the Chinese mulberry silkworm Bombyx mori, ever since someone figured out 6,000 years ago how to unravel the threads from the caterpillars’ cocoons and weave them into gorgeous textiles for China’s emperors. The Chinese managed to keep the process secret for centuries, until it became the object of history’s first known instance of commercial espionage. In the sixth century A.D., according to legend, the European emperor Justinian dispatched two monks to China. They returned with both the silkworm eggs and seeds for the mulberry trees on which they feed, smuggled home inside bamboo walking sticks.
The result today is a global industry. China is once again leading the world, producing 58,000 tons of silk annually. (And that is a lot of caterpillars.) The United States also had a thriving silk industry, until the introduction of nylon in World War II. My family was among the many that benefited from it: My grandfather was a warper at silk mills in Manchester, Connecticut, and Paterson, New Jersey. So without silkworm wages—not to put too fine a point on it—there would be no me.
Now back to the new research, just out in the journal Biomacromolecules. British researchers have devised a means to continuously milk silk from living silkworms. This is a big deal because of an unfortunate fact behind the loveliness of silk: Up to now, the only way to unravel silk was to Read the rest of this entry »
