- the accompanying flow will flow out. Since the accompanying flow is guided between the nozzle holes through the accompanying flow introduction passage, the combined molten glass can be easily separated. Furthermore, the molten glass drawn from each nozzle hole is cooled by the accompanying flow.
- the molten glass increases in viscosity and solidifies before the flatness decreases due to surface tension, so that glass fibers having a high flattening rate can be obtained.
- the plurality of glass outflow portions are arranged in a direction orthogonal to the parallel direction of the two nozzle holes, and the associated flow introduction passage extends in the arrangement direction of the glass outflow portions, It is preferable to have a discharge section for discharging the accompanying flow between the nozzle holes.
- the accompanying flow can be discharged from the discharge portion of the accompanying flow introduction passage, and can be efficiently sprayed on the molten glass drawn out from each nozzle hole.
- the method for producing glass fiber according to the present invention is directed to a glass fiber which uses a pushing having a glass outflow portion in which two substantially flat nozzle holes are juxtaposed, draws molten glass from each nozzle hole and spins the glass fiber. The method according to the above, wherein when the molten glass is drawn out from each nozzle hole, an accompanying flow that flows along with the drawing of the molten glass is introduced between the nozzle holes.
- the accompanying flow is introduced between the nozzle holes, so that the accompanying glass is drawn out of each nozzle hole by the accompanying wind force.
- the molten glass is prevented from approaching, and the molten glasses are less likely to merge.
- the associated flow starts flowing out when the spinning operation is restarted and the molten glass is pulled out from each nozzle hole. Since the flow is guided between the nozzle holes through the associated flow introduction path, the molten glass can be easily separated.
- the molten glass drawn from each nozzle hole is cooled by the accompanying flow. For this reason, the molten glass increases in viscosity and solidifies before the flatness decreases due to surface tension, so that glass fibers having a high flattening rate can be obtained.

- FIG. 1 is a bottom view showing the pushing 10 of the present embodiment
- FIG. 2 is a schematic configuration diagram showing a glass fiber production system 1 for producing glass fibers using the pushing 10 shown in FIG. It is.
- the glass fiber manufacturing system 1 includes a melting furnace 2 in which a bushing 10 is mounted on the bottom surface and a molten glass stays, and the molten glass spun from a nozzle hole of the pushing 10 is cooled. This turns into a filament.
- the filament spun from the pushing 10 of the present embodiment has a flat cross section.
- a sizing agent application roller 4 is provided below the pushing 10, and the sizing agent is applied to the filament by the sizing agent application roller 4. Further, the filaments coated with the sizing agent are bunched by the bunching roller 6 to form strands, and glass filaments can be obtained. After that, the strand is turned on the rotating drum 8 It is wound up into a so-called cake.
- the above is the glass fiber production system
- the pushing 10 is provided with a glass outflow portion 18 in which nozzle holes 12 having a flat cross section are arranged in parallel with the longitudinal direction thereof being parallel.
- a plurality of the glass outflow portions 18 are arranged in a direction (Y direction) orthogonal to the direction in which the nozzle holes 12 are arranged in parallel (X direction in FIG. 1) to form a row of nozzle blocks 30.
- a plurality of the nozzle blocks 30 are arranged in the X direction.
- FIG. 3 is an enlarged view of a region surrounded by a two-dot chain line A of the pushing 10 shown in FIG.
- FIG. 4 is a cross-sectional view taken along the line IV-IV of FIG. 3, and FIG. 5 is an enlarged perspective view of the glass outflow portion 18 shown in FIG.
- a cutout portion 14 cut into a rectangular parallelepiped shape is formed between the nozzle holes 12, and further, in the longitudinal direction of the nozzle holes 12.
- a groove-like associated flow introduction path 20 extending along is formed.
- the wake flow introduction channel 20 extends in the S row direction of the glass outflow portion 18 (see FIG. 3).
- the accompanying flow means a wind that flows as the molten glass is drawn from the nozzle hole 12.
- the associated flow introduction passage 20 extends to the end of the nozzle block 30, and its cross-sectional shape is a concave shape having a corner.
- the molten glass drawn out from each nozzle hole 12 has a flat shape immediately after drawing since the nozzle hole 12 has a flat shape following the shape of the nozzle hole 12.
- the drawn glass has a reduced flattening due to surface tension, and the cross section of the glass fiber tends to approach a circular shape.
- the molten glass drawn out of the nozzle holes is cooled by the accompanying flow introduced into each nozzle hole 12, so that the flatness of the molten glass is reduced by the surface tension. Before the viscosity increases and solidifies. As a result, glass fibers having a high oblateness can be obtained.

- the nozzle hole 12 of the modified example shown in FIG. 9A has a rectangular shape
- the nozzle hole 12 of the modified example shown in FIG. 9B has a dumbbell shape obtained by combining circles at both ends of the rectangle. Even when the nozzle hole 12 has such a flat shape, a glass fiber having a flat cross section can be obtained.
- the cross-sectional shape of the trailing flow introduction path does not necessarily have to have two corners, and can be variously changed to a semicircle, a triangle, or the like.
- the accompanying flow that flows as the molten glass is drawn out of the nozzle hole passes through the accompanying flow introduction passage, and flows into each nozzle hole. Guided between. Therefore, the molten glass drawn out from each nozzle hole is prevented from approaching due to the accompanying wind force, and the molten glasses are less likely to merge during spinning.
- the accompanying flow starts flowing out, and the accompanying flow Is adjoining flow Since the molten glass is guided between the nozzle holes through the entrance path, the joined molten glass can be easily separated. Furthermore, the molten glass drawn from each nozzle hole is cooled by the accompanying flow. For this reason, the viscosity of the molten glass increases before the flatness decreases due to the surface tension, and the molten glass solidifies, so that glass fibers having a high flattening rate can be obtained.
