ABSTRACT:
The invention relates to a glass microfibre based paper, the said fibres being obtained by centrifugal processing of molten glass which is drawn by an annular gas flow at elevated temperature and velocity, which passes along the peripheral wall of the centrifuge. The centrifuge rotates at a peripheral velocity of between 50 and 20 m/sec. and the quantity of glass drawn is less than 6 tons per day and per meter of centrifuge periphery in the case of microfibres of 2 to 3 microns and less than 1 ton per day and per meter of centrifuge periphery in the case of microfibres of less than 1 micron.
