A plurality of melt spinning nozzles having pores are extruded through dies arranged linearly in the width direction, and at the same time, a gas such as air at a linear velocity of 10 to 1000 m/sec and a temperature of 25 to 60° C. is blown around the nozzles. forms a fiber stream consisting of drawn ultrafine fibers. The blowing of the fibers at this time can be adjusted by the gas pressure.

が発生するために好ましくない。In the present invention, this rolled silk fiber stream is heated by a heating device, such as an infrared heater or a microwave heater, installed at a space below the die to evaporate and remove water in the fibers. The residual moisture content in the fibers heated in this manner is preferably 10% by weight or less, particularly 8% by weight or less. If water is insufficiently removed, a nonwoven fabric will not be formed, but will become a highly viscous liquid, making it impossible to obtain a nonwoven fabric with ultrafine fibers. The heating temperature for the fiber stream is selected depending on the balance between the extrusion amount of the PVP raw material liquid, the temperature of the blown gas, and the wind speed, but it is usually preferably in the range of 80 to 120°C. If the heating temperature is made higher than necessary, it is not preferable because PVP decomposition occurs along with removal of moisture.

ことにより関節することができる。The dehydrated and stretched polar flII Elk fibers fall entangled onto a collection device, such as a net or porous rotating drum, moving belt, etc., to form a nonwoven fabric. In addition, when collecting the fiber stream, if the fiber stream is sprayed onto the contact point of two rotating net-type collection drums,
The intertwined fibers are distributed in the thickness direction of the nonwoven fabric (i.e. three-dimensionally).
An arrayed, bulky nonwoven fabric is obtained. In addition, if the fiber stream is sprayed onto a point other than the contact point of the collection drum or onto a flat collection belt, a nonwoven fabric in which the fibers are arranged parallel to the plane (i.e., two-dimensionally) can be obtained. It will be done. Further, the basis weight of the nonwoven fabric can be adjusted by changing the moving speed of the fiber flow collecting device.

る。As described above, the PVP nonwoven fabric of the present invention is made of extruded PVP.
The stretching ratio of the fibers is increased from 10 to 3000 times, preferably from 20 to 1000 times, by blowing a high-speed air stream onto the VP fibers.
A nonwoven fabric made of ultrafine fibers is made by doubling the size and heating the fibers to rapidly evaporate the moisture in the fibers.

た後、巻取装置３４に巻取られる。Next, an example of manufacturing the PVP nonwoven fabric of the present invention will be explained using the attached drawings. FIG. 1 is a schematic side view showing one example of an apparatus for manufacturing a nonwoven fabric of the present invention. An aqueous solution of PVP or a molten liquid plasticized with water is supplied from a raw material supply pipe 1 to a raw material tank 2 . This raw material liquid is pushed out from the spinning nozzle 5 by a gear pump 4 driven by a motor 3, and at the same time, high-pressure air supplied by a blower 6 provided around the spinning nozzle is blown downward from an air nozzle 7 to form water-containing pvpuIi fibers. Next, the water-containing PVPIJIi fiber stream 8 is heated by a far-infrared heater 9 installed below the die in parallel with the fiber stream 8 while being collected by a net-type collection drum 11 to form a fiber stream 8. The moisture inside is removed by evaporation. Stretched and dehydrated p
The vp fiber stream falls intertwined with the contact points of two rotating net-type collection drums, is compressed to form the nonwoven fabric 12, and is then wound up on a winding device 34.
