摘要:
Method and apparatus for the production of fibrous materials from attenuable substances, particularly molten glass, are disclosed, along with the fiber products which result. In the disclosed system the material to be fiberized flows into a region established as a result of the interaction of a jet transversely oriented with respect to a larger blast, the material being acted upon in the interaction zone to produce a highly attenuated fiber.

METHOD AND APPARATUS FOR PRODUCING MATS OF GLASS FIBERS THAT ARE ATTENUATED BY HIGH VELOCITY GASES AND WHEREIN A MIST OF A WATER SOLUTION OF WATER SOLUBLE GLASS LUBRICANT SUCH AS ETHYLENE GLYCOL, IS APPLIED TO THE FIBERS, EITHER DURING THEIR ATTENUATION BY THE HIGH VELOCITY GASES, OR PRIOR THERETO.
摘要:
FOAMALBLE FIBERS OF ALKALI METAL SILICATE GLASS ARE PREPARED BY DISPERSING FLOWING FINE STREAMS OF MOLTEN GLASS TO CENTRIFUGATION OR TO A HIGH VELOCITY BLAST OF GAS THEREBY FORMING FIBERS OF RANDOM LENGTH AND AVERAGE DIAMETERS IN THE RANGE 0.1 TO 1.0 MIL, AND HYDRATING THE RESULTING STAPLE FIBERS TO A MOISTURE CONTENT OF 5 TO 40% BY TREATMENT WITH STEAM OF A WATER SPRAY. IF DESIRED, FIBERIZING MAY BE EFFECTED BY CENTRIFUGALLY DISPERSING THE MOLTEN STREAMS IN A FIRST STEP AND THEN SUBJECTING THE DISPERSED STREAMS TO THE HIGH VELOCITY GAS BLAST. THE GAS IS PREFERABLY SUPERHEATED STEAM, HOT COMPRESSED AIR OR A FUEL GAS FLAME. THE THUS-HYDRATED PRODUCT MAY BE FOAMED BY CONVENTIONAL FOAMING TECHNIQUES.
