If you’re wondering where most of your silk comes from and the specialties of these countries, we’re going to go inside the silk industry itself in Thailand, Japan, and China to see just what it is that they’re making and how.
Silk production in Thailand is very specialized. The Thai silk moth is most suited to tropical conditions. This moth is what is called polyvoltine, meaning it can produce at least ten batches of eggs each year. They hand reel the silk from the Thai moth from green cocoons. These cocoons still contain the live pupae. The pupae from these cocoons are not killed before being reeled because that would make reeling very difficult. What they do is they place the green cocoons in hot, almost boiling water. This process loosens the end of the thread. They only have about 10 days to finish this process before the moths come out and ruins the cocoon. Many times, the workers run out of time. This limits the scale of the industry and partially explains why silk is so expensive. The most experience workers usually only produce about 300 kg per day.
Silk production in China and Japan is a little different. The moth that...
