Thanks for your reply Bill!

And thanks for mentioning the confusion with tex and thread count - a was also a bit confused myself (therefore i wrote the article).

How would you know wether 210T refers to thread count or Tex?

According to wikipedia (I know, not necessarily the best source, but the article seems "expert written"):

https://en.wikipedia.org/wiki/Units_of_textile_measurement

"Various units are used to refer to the measurement of a fiber, such as: the denier and tex (linear mass density of fibers)"

If you can give me a better source(?), I will go ahead and change it right away!

And you are right about the surface treatments as well, I will add a section on that (had it included in a newer article, but should probably add it here as well...)

Thanks,
Andy
