David, not sure about today, but as of 5 years ago there were only 5 manufacturing facilities in the world producing the "micro-fiber" cloth.
2 in Korea and 3 in China.
Ever read the little tag on a cloth?
They produce what the "customer" wishes to "re-market", under what ever brand name the customer wishes.
Back in the late 70's and early 80's a wonderful fabric was presented for shirts, etc, it was called "Ultra-Suede" and was a micro fiber cloth.
One may go to Wal-Mart, AutoZone, etc, or on-line and find many micro fiber offerings.
Ever notice that there are only two blends, 80/20 or 70/30 and then perhaps a "waffle weave" offering?
Like anything, these mills will produce whatever "quality" of a product their buyer wishes to purchase,and sew the tag of their brand on them.
However, have you ever seen one that said other than "made in Korea" or "China"?
I know that some sort of cheat on this and I realize that I am a bit out of the loop on these sort of things.
Rob out of Santa Barbara, Ca has a great selection of quality towels, which he has been dedicated for years to insuring that they are real quality.
When I want the best I go to him, when I want a plain old micro-fiber, "who's cheap".
Just a bit of input.
