Drew,

I heard both stories - silk replacement and hemp replacement - from the
History Channel and PBS. I can't remember exactly what year, but it was
during the early stages of WWII. I do recall it was by accident (?),
similar to what happened with Lexan.

I remember it was after plexiglass because plexiglass was used on the
canopies and gun turrets.

Lee,

What was the original engineering need?  Was it to replace silk for
stockings as 
has been indicated, or was it some other war time need that started the 
creation of nylon.  

My understanding is that fiberglass rope was to replace hemp rope
because 
the hemp supply was cut off as the war progressed.  They had farmers 
stateside growing hemp as one approach to the problem.  Fiberglass
turned 
out to be superior in some ways.
