Dera, this is great information!
I am a bit knowledgeable regarding fabrics, but not for use as clothing. What is the reason why a bit of silk blend is not favorable? The reasons I've heard for it was that it helps prevent wrinkles. As for 100% wool fabrics, I would say the best fabrics come from the UK. I am thinking that Samsung just bought the wool from various places on the market and used that to make fabric.
