Hi Kim!
The hollow fiber means the glass fiber which has a capillary in itself.
If the molten glass contains a sufficient level of impurities or gas bubbles,
air will become trappeed inside a fiber.
See the following material:
Anand A. Shukla,etal."Hollow Fibers in Woven Laminates" Printed Circuit Faburication,
Vol.20,No.1,p30-32(1997.1)
