Dear Technetters:

 Have you ever experienced or heard of hollow fiber ?
  Is this in the state of hollowing between fibers or fiber itself?
  For the former, I think poor soaking of resin is the cause and the latter
is intentionally developed
  fiber to reduce Dk.
  Do you have any idea to improve soaking tight bundle of fiber?
  Any comment to this is appreciated.
