A hot-air supply device 4 to be introduced is provided.
The fourth nozzle units 6a to 6d can be divided.
[0036]
The split nozzle unit 6 is more specifically a molten I dissolved resin flow path. It divides | segments so that 10 and the hot air flow path 12 may each be divided into plurality. This
As a result, several different nozzle units can be pre-applied for various fiber specifications.
It is easy to replace a part of the nozzle unit according to the fiber specifications.
. For example, when changing the specification of the fiber to be manufactured, the molten I dissolved resin discharge port 9
And the fourth nozzle unit 6d formed with the hot air discharge port 11 is taken out and changed.
A molten I dissolved resin discharge port 9 and a hot air discharge port 11 corresponding to the specifications of the subsequent fiber are provided.
It can be easily replaced with the formed fourth nozzle unit 6d. Yo
Therefore, it is excellent in workability when manufacturing the desired nanofiber, and shortens the work time.
From the fine fibers that have been reduced in cost and the fibers.
It becomes possible to provide the nonwoven fabric etc. which become efficiently.
12045653_1 (GHMatters) P112919.AU [0037]
Furthermore, the discharge nozzle 2 of the present embodiment has a melting I dissolving structure consisting of a plurality of discharge ports.
Resin outlet groups 9-1 to 9-12 are formed, and resin is discharged from a plurality of outlets.
The hot air discharge port 11 formed as a single slit arranged in a horizontal direction
Hot air is blown out. Because of this, each molten I dissolved resin discharge port
Hot air blown out to molten I dissolved resin discharged from groups 9-1 to 912
The amount can be made uniform. This suppresses unevenness in the quality of the molded fiber.
And high quality fibers can be obtained.
[0038]
Further, the divided first to fourth nozzle units 6a to 6d are bolts or the like.
Since it can be easily and integrally assembled by the fixing means 8 comprising
It is possible to shorten the time of complicated assembly and disassembly work, and in turn is manufactured.
The cost of the fiber can be kept low.
[0039]
As mentioned above, although the present Example was described, this invention is limited to the said Example.
However, various modifications are possible within the scope of the present invention. Real
In the embodiment, each of the first to fourth nozzle units 6a to 6d that can be divided into four parts is provided.
A molten I dissolved resin flow path 10 and a hot air flow path 12 are formed. -The part where the melted resin flow path 10 and the hot air flow path 12 are formed can be further divided.
May be configured. Of course, the number of divided units may be reduced. Explanation of symbols
