I could be wrong, but hollow fibers are trivially simple to make... they can be pulled out of a beaker. I believe solid fibers have to be extruded.
Nothing is inexpensive these days.

you might be right, i know nothing of the process, it just seems like synthetic insulation has gotten more expensive as things shifted to hollow fibers and such, and the cheap stuff from WM that doesn't compress has gotta be solid fiber otherwise it would be more compressible (that's my reasoning anyway)
On second thought, solid fiber would not be extruded, but more probably spun the way they make synthetic thread. It's also pulled out of a beaker.
Kinda fun to watch. I have a friend who used to work for a textile mill. He bought a couple of huge machines real cheap, and for years made net bags for hams. Recently, he sold the business lock, stock and barrel to another fellow. Anyway, to keep those huge machines going, he had a little reciprocating rig on a bench, that pulled thread out of a beaker all day long, completely unattended.

that would be interesting to watch
I have been on a field trip (10 years ago?) to the local Monsanto Plant (now Solutia, I think), and watched them making nylon thread, mainly used in the carpet industry. Very intersting. I have several friends who are retired from there and others work there still.

I'm definately curious to see the Wiggy's bottom insulation. Make sure you post pics.
My blanket from Wiggys shipped today. Will measure and take pics when it arrives.
