One of the common threads (pun intended) in both my mystery series is the importance of weaving. It is not hyperbole to say that without the weavers – most of them women – there would be no cloth and no clothes. Until the Industrial Revolution, when weaving was mechanized, all of the cloth was woven by hand weavers on looms.
Wool is a forgiving thread to weave. It has a little stretch. Linen is harder since the threads have no stretch at all. Silk, with his hair fine threads, is truly difficult.
The myth around the invention of silk goes like this. In about 2700 B. C. E., an emperor’s wife was sipping hot tea when the cocoon of a silkworm fell into her cup. The hot liquid dissolved the sticky coating and the threads unwound. Genetic traces and archaeological finds put the domestication of the silkworm to between 4000 and 5000 years ago, though wild silk may have been woven by then. Chinese archaeologists say they found traces of silk in the soil in a tomb from around 8500 years ago. Wow!
Millennia of selective breeding created the B. Mori moths that are blind and white. They lay eggs on mulberry leaves. The larvae feed on the leaves and then spin the cocoons. The silk is made up of two proteins – fibroin and sericin. The process of stretching and spinning these proteins through an opening near the worm’s jaw creates the solid fiber. Although finer than a human hair, silk has tremendous tensile strength.
One thing I didn’t know: silk is used in medicine. Because it decays slowly in the human body, leaving nothing behind, and is strong, silk is used for surgical sutures. It has been used for centuries as bandages. And the Chinese used it in armor. Silk help shield any wounds.
