Kay Lanchaster just - correctly - sent me the following information: my
wording "polyester fleece" was an incorrect attempt to translate the
german wording into english. Indeed, reemay is:

> What I know as Reemay is a thin, non-fleece spun-bonded polyester

> interfacing; light penetrates it readily.

I have been researching a bit about reemay some years ago. It seems that
for some applications, there will be additives to the "original"
material (like UV-blockers etc.). For conservation purposes it seems to
be important to get the basic material. So - a bit like for tyvek - the
cheapest sources for broad application might not always be the most
useful ones. General uses for Reemay are: filtration (accepted for use
with food), Textiles, Agriculture, laundry (support for softeners) etc,
etc. See: http://www.reemay.com/
A similiarly interesting product is: Typar (R) and Tecton(R), non-fleece
spun-bonded polypropylene.

The penetrability by light does not seem to be a limiting factor for
interlinig textiles, it will, however, as an outer layer. Therefore my
suggestions in my last posting (densely woven cotton fabric or tyvek)

Reemay comes in a very broad variety of structures, from lightweight and
smooth surface to very stiff and "scratchy" surface. For interlinig
Textiles  e.g. Reemay 2250 (17g/m2) to me seems very useful. For making
support forms (forming with temperatures of 93-107°C (= 200-225 °F)),
more heavy weight reemay  or Typar / Tecton would have to be chosen.

Please keep in mind the risk factor of melting at elevated temperatures
similar to ethafoam etc.
