Haa. Ask the conservators at Borås museum about clothes made from
synthetic materials. They end up having to throw away designer clothes
from 60's and 70's due to the fact that the materials disintegrates !
And nothing can really be done - no pesticides which can prevent
plastics from disintegrating.
Borås museum due to the town's history as a clothing industry cluster
(think New York's cloth industry but of course smaller) has a large
collection of clothing.
