I'm nearly certain I already know the answer to this question, but the reason I am asking is because I was told some rather curious information by a man who claims to have been in the cloth and garment business for 10 years. Anyway, I walked into a tailors shop here in the Middle East that was run by a Turkish man. He has various bolts of cloth on display that he uses to make MTM and bespoke suits. Some bolts were a very fine material and others were a more rough wool like tweed. Anyway, I was looking at some of the cloths and asked the owner if his materials were 100% wool. He told me no, that you cannot find 100% wool that is soft and smooth. If it is pure wool it will always be rough like a tweed. I looked at him a bit cock eyed for a moment and asked what his fabrics were made of if not 100% wool. He said that all his fabrics were either a blend of wool and silk or wool and polyester, or some other material.
Ok, so help me out here. Is there some little known esoteric thing about wool material that I am unaware of? Is it true that fine soft material for suits will never be 100% wool? I feel like a fool for asking because I have been a suit wearer for years and I'm almost certain this guy didn't know what he was talking about. But he did say he was in the garment business for 10 years so I had to stop and wonder for a moment. The answer to this question will affect whether I go back to get a suit made by him.
