It's a very well-known problem among the museum conservation crowd
--and
with no practical solution.
For a discussion, WikiPedia is pretty informative:
Textilmuseet (textiles and clothes museum in Bor?s, Sweden) have a
number of items which was haute couture in the 70s and 80s. Some of
them was done in a plastic which today is basically an awful mess...
And so they are basically forced to thwrow away items which cost them a
fair bit to buy.
