We wore white nylon gloves a lot more than we wanted
to back when I was
a COM operator producing Microfiche in the 80's. I suspect they're
still readily available. Probably anybody who handles a lot of film
would use them, i.e. the photograpy market.
You cna get white film-handling gloves (which I thought were cotton) from
Jessops in the UK (that's a common high-street photographic shop). Any
halfway-decent photographic shop, the sort of place that sells chemcials
and paper for home processing, etc, would have them, I think.
