い。 In FIG. 8, the thermoplastic material is supplied to the hopper 11 of the extruder, heated and melted by the extruder 5, supplied to the die 6 installed in the extruder 5, and continuously spun from the spinning hole 61 of the die 6. Ru. The die 6 has a gas discharge hole 62 adjacent to both sides of the spinning hole 61 and a gas supply pipe 6 that supplies gas to the gas discharge hole 62.
3 is installed. The high pressure gas supplied to the gas supply pipe 63 of the die 6 is discharged from the gas discharge hole 62 at a speed close to the speed of sound. The thermoplastic material spun from the spinning hole 61 is turned into fine fibers by the high-speed airflow discharged from the gas discharge hole 62, and forms the fiber stream 7 together with the gas. After the fiber stream 7 comes into contact with droplets 101 supplied from a droplet supply device 10 provided as necessary (contact with the droplets is not essential), the fiber stream 7 is sprayed onto the fiber spraying portion P of the collecting plate 8. The collection plate 8 is a mesh or perforated plate made of metal or synthetic resin, and the size of the mesh is 5 to 200 meshes, preferably 5 to 100 meshes, more preferably 10 to 40 meshes, and has a hollow cylindrical shape. It is installed on the surface of the drum 81. The drum 81 has a hollow cylindrical shape, and a large number of through holes are installed on its side. The shape of the through hole 83 installed on the side surface is circular as shown in FIGS. 9 and 10, and the diameter of the outer opening 85 is larger than the diameter of the inner opening 84, which is a so-called tapered hole. A desirable example is the case where . The fibers sprayed onto the surface of the collecting plate 8 as the fiber stream 7 are separated from the fiber stream 7 to form the nonwoven fabric 1, which is pressurized to a predetermined thickness by the presser plate 9 and then rolled into rolls 71, 71'. Winder 13
It is wound up. The holding plate 9 is a net or perforated plate similar to the collecting plate 8, and a drum 9 similar to the drum 81.
1 and is wound around the drum 91'. Reference numeral 12 is a fiber collecting section, and 14 is a cooling spray for the collecting plate 8, which may be installed as necessary.

繊維は交絡し積層して不織布１となる。 The nonwoven fabric of the present invention can be efficiently produced by the method described above, and the process of producing the nonwoven fabric will be schematically explained with reference to FIG. 11. A fiber flow 7 formed from a plurality of long fibers is blown onto a fiber collection section 12 surrounded by a collection plate 8 and a presser plate 9, and each fiber is entangled and laminated to form the nonwoven fabric 1.

It depends on the relative positional relationship between 8 and presser plate 9. That is, if the blowing angle of the fiber stream 7 is small or the positional relationship between the collecting plate 8 and the holding plate 9 is different, the shape of the thin layers 4, 4',
