摘要: A HIGHLY TEAR RESISTANT NONWOVEN MAT OF THERMOPLASTIC POLYMER FIBERS IS MADE IN MELT-BLOWING PROCESS WHICH MOLTEN POLYMERIC RESIN EXTRUDED THROUGH ROW DIE OPENINGS INTO STREAM HOT GAS ATTENUATES THE HAVING DIAMETERS BETWEEN ABOUT 10-40 MICRONS. ARE COLLECTED ON CONTINUOUSLY MOVING SURFACE POSITIONED FROM 10 TO 30 INCHES OPENINGS.
