Abstract
Herein is described a process for drying wet glass fibre forming packages, the process comprising: providing a wet glass fibre forming package comprising a strand of glass fibres with an aqueous sizing applied to the glass fibres; and subjecting the wet glass fibre forming package to microwave radiation having a frequency in the range of about 750 to about 1050 MHz.
Claims12
A wet glass fiber forming package processing system, the system comprising:
- a glass fiber producing apparatus comprising a bushing for extruding glass fibers;
- an aqueous sizing applicator for applying an aqueous sizing to the glass fibers extruded from the bushing to form sized glass fibers;
- a strand forming device for forming a glass fiber strand from the sized glass fibers;
- a winding device for forming a wet glass fiber forming package from the glass fiber strand;
- a magnetic metal support for supporting the wet glass fiber forming package;
- and
- a microwave drier configured to dry the wet glass fiber forming package on the support to form a dried glass fiber forming package by subjecting the wet glass fiber forming package to microwave radiation having a frequency in the range of about 750 MHz to about 1,050 MHz.
