I had the same question and concern when I watch it. We are on the same boat. Lol!Call me old-fashioned, but watching this video makes me feel uncomfortable. I see mass production, not what I have in mind when I hunt for a certain design.
Second, and more important: in my eyes this is not the way H silk should be treated, messing around between machines (oil!). Seeing this I wonder if the silk seen in the video ended up in retail?
To me this video does not showcase silk manufacturing but a woman messing around with delicate scarves.
I am amused, how conservative I am.
