I'm aware of two articles that might help you get started in your
"Cotton is Period? Really?" <http://des.kyhm.com/cotton
> addresses the
early history of the fiber modernly called "cotton", including its
introduction to Europe and its usage at various times, primarily in
Italy. A bibliography is given.
"Cotton in the Middle Ages"

meaning of the term "cotton" in early sources, but includes some
comments on the history of the availability and uses of the fiber we
now call by that name. Most of its information comes from a single
book, cited in the text.
