Silk worms doing their thing

It was a visit to a silk factory (and adjoining shop, of course) this morning.  Actually I found it quite interesting to see the whole cycle, and how they make the finished product.
The first pic is a moth emerging from the cocoon (normally they are baked or boiled before this happens, as the moth bites and breaks the thread as it emerges.
Following images show the silk thread being teased from the cocoon and spun into thread reels.
Finally, workers are making a silk duvet filler by stretching out great wads of the stuff.
