Well, they need a specific sort of tree so perhaps a positive aspect of the silk industry is that lots of those trees are planted and kept healthy and thriving to support the worms. And it's a natural fiber which is produced without tons of nasty chemicals because the beings making it are, well, bugs. Sensitive to all the things that get sprayed on cotton plants etc.
It's slippery? It sure doesn't have the same qualities as a sticky thing like wool! Interesting that they do unwind it. I can't even imagine the time involved in that. Makes you wonder how they can sell silk garments for as cheap as they do even taking near slave labour wages into consideration. It is such a precious thing, just unbelievable amounts of work. Wow.
So... this is how they spin fine silk thread? I ridiculously thought, I don't know why because this is crazy, that the cocoons were unwound then spun together into threads. I know silk has that lovely shiny sheen from being woven of very long fibers but I can't be right about how it's put together into thread for things like the vintage kimono my friend brought back from Japan for me... Amazing process. So many creatures died for that garment, it's nearly unthinkable when you stop to really consider it.
I'm pretty sure you can start another one! There was just an exhibit in Toronto so it seems to still be relevant. I'm going to see what I can find in my city, I so want to participate in making some of those incredible sea creatures.
