Abstract

PURPOSE:To provide a spinning pack improved in mixing or filtration efficiency of a molten polymer by arranging a packed bed prepared by compression forming a metallic staple fiber group through a filtering filter on a breaker plate on a spinning nozzle. CONSTITUTION:This spinning pack for melt spinning of synthetic fibers is obtained by arranging a breaker plate 3 having many bored holes on a spinning nozzle 1 installed at the lower opened end of a casing 5 and further arranging a packed bed 6 prepared by compression forming a metallic staple fiber group having nearly a polygonal cross section at 10-100 aspect ratio such as stainless steel and many unevennesses formed on the surface into a blocklike shape through a filtering filter 2 thereon. Even when a molten polymer is pressed from a pressing inlet 8 under an unequal pressure, the packed bed 6 has the rigidity and is three-dimensionally supported in the form of a bridge. Thereby, a uniform bed thickness can always be kept to apply a uniform pressure for passing the molten polymer therethrough. As a result, the uniform filtration can be carried out to feed a uniform throughput to the spinning nozzle 1.

SUMMARY OF THE INVENTION In the prior art,
The sand 100 is a powdery or granular material having high dispersibility or fluidity. Therefore, the molten polymer A
If the powder flows into the surface of the sand 100 in a non-uniform state such as a teardrop at the start of press-fitting, the local pressing force causes the highly dispersible powder particles to roll and form a concave portion in the layer of the sand 100. , A thick part and a thin part occur. As a result, the molten polymer A is continuously pressed into the spinning pack in a state where the layer of the sand 100 has a concave portion and the layer thickness is not uniform. Therefore, the pressure applied to the molten polymer A is not uniform. However, there is a problem in that mixing and filtration are insufficient and spinning breakage occurs.

In the present invention, the filler layer having the aggregate structure of short metal fibers is provided in the region where the molten polymer is press-fitted. Since the short metal fibers have an aspect ratio of 10 to 100, they are entangled with each other. Therefore, dispersion or movement is restricted. Therefore, even if the molten polymer is non-uniformly press-fitted, the local inflow pressure can be received in a substantially large area, so that the recessed portion is not formed in the layer and the layer thickness is kept uniform. The molten polymer flows down through the voids of uniform layer thickness. Therefore, the preload is made uniform and
Mixing and filtration are sufficient, and in this state, the filter is pushed out through the breaker plate and the nozzle hole.
When a metal short fiber having a substantially polygonal cross section and a large number of irregularities on the surface is used, the entanglement is enhanced, and the molten polymer is sheared at the edge of the polygon, so that the filterability is improved. And the mixing property is further improved.

The short metal fibers 7 are made of a material such as stainless steel that does not have a chemical adverse effect on the polymer to be spun and have an aspect ratio (length L / diameter D) of 1.
It is 0 or more. When the aspect ratio is 10 or more, the entanglement property becomes insufficient at a value less than this, the dispersion resistance is weakened, and when the molten polymer is pressed into a droplet, it loses its flow pressure and moves. This is because the recessed portion is easily formed. The upper limit of the aspect ratio is about 100, and if it exceeds this value, the entanglement property is good, but since it becomes a lump and the density becomes non-uniform, or the rigidity becomes poor and the concave portion is easily formed by the fluid pressure, Not very suitable. Therefore, the aspect ratio is usually 10-100,
It is more preferably 15 to 70. As a specific example, the length is 1.0 to 3.0 mm with stainless fiber, and the converted diameter is 30.

The metal short fibers 7 may be obtained by cutting long fibers produced by, for example, a focused wire drawing method. However, this method is expensive because it is made by many steps, and the fiber shape is circular in cross section and the surface area is small, and the surface is smooth, so the entanglement tends to be insufficient. The porosity of is likely to be low. The most preferable metal short fibers 7 in the present invention have a large number of irregularities 70 on the surface as illustrated in FIG. 4, and have a polygonal cross section such as an equilateral triangle, an isosceles triangle, or a trapezoid. Is close to. The metal short fibers 7 are not limited to those having a straight fiber axis direction, but also those having a curvature or a twist.

Typical of the above-mentioned short metal fibers 7 are:
It is manufactured by the chatter vibration cutting method. This chatter vibration cutting method is to rotate a metal block (including coil material) while applying a tool to the surface of the metal block with a predetermined cut, and at the same time give a minute feed to this tool while deliberately performing self-excited vibration (chatter vibration). ) Is caused and the metal block surface layer is forcibly sheared and broken by its self-excited vibration.Specifically, for example, an elastic tool with a high natural frequency such as an elastic tool is used and the cutting (cutting) Width): 0.5-5
mm, cutting speed: 20-300 m / min, tool feed: 0.0001-
The conditions may be appropriately selected from 0.02 mm / rev and self-excited frequency: 100 to 5000 Hz. This makes the converted diameter 10 to 100
It is possible to directly mass-produce short metal fibers of μm from raw materials. The short metal fibers 7 produced by this method have high strength due to work hardening, and since the fiber axis direction is perpendicular to the cutting direction, there are few surface defects due to notches as in the case of turning type long fibers. Moreover, the cross section has a substantially polygonal shape as illustrated in FIGS. 4 (a) to (c), and a wrinkle surface having a large number of ridges running in the fiber axis direction on the free cutting surface side, and the moment of becoming a fiber. Since it has a rough fractured surface caused by fracture separation, it has a high proportion of roughened surface as a whole and has a very large surface area.

The filling layer 6 may be constructed by directly inserting the metal short fibers 7 into the casing 5 and appropriately increasing the density. This is to put a required amount of the short metal fibers 7 directly into the casing 5 above the filter 2, and in this state, press the metal short fiber group from above with a plate-like or block-like pressing means to reduce the bulk. It is realized by repeating the operation of uniformizing the thickness an appropriate number of times. Entanglement of the short metal fibers 7 is strengthened by the above operation. Alternatively, a cartridge having a predetermined thickness and density may be already formed as shown in FIG. 4 before loading into the casing 5. For example, the metal short fibers 7 are loaded into a female die (die) having a recessed portion, a male die (punch) is pushed in to perform compression molding, and an adhesive having a melting point lower than that of a polymer to be spun is bonded to the molded body. Synthetic resin 8
(For example, when the polymer is polyester, nylon) may be applied, or the molded body may be dipped in the synthetic resin solution. According to this, the short metal fibers 7 are bound by the adhesive force of the synthetic resin 8 to form a block solidified to a predetermined thickness and density, so that the filling layer 6 can be easily formed in the casing without scattering around. Since the fluid (including the molten polymer for the dummy) having a temperature higher than that of the synthetic resin is injected into the casing 5 before the spinning operation is started, the synthetic resin 8 is melted and extracted. The filling layer 6 in which the short metal fibers 7 are assembled can be used.

In the present invention, the filling layer 6 is formed by assembling the short metal fibers 7 having an aspect ratio of 10 or more, and the short metal fibers are intertwined with each other firmly. For this reason, even if the molten polymer obtained by polymerization in a nitrogen atmosphere or the like is pressed into the inside from the pressure inlet 8 at an unequal pressure and flows in a teardrop shape as shown by an arrow, it is still metallic. In addition to being rigid, the movement is restrained by the entanglement with each other, and the press-fitting load is dispersed and received because it is supported in a three-dimensional bridge shape. Therefore, unlike the conventional sand, a concave portion is not generated by the fluid pressure, and the filling layer 6 always allows the molten polymer to pass while maintaining a uniform layer thickness. Therefore, the applied pressure becomes uniform, mixing and filtration are sufficient, and the amount of extrusion is controlled to the required amount through the filter 2 through the holes of the breaker plate 3 and extruded from the spinning nozzle 4 to the outside to cause spinning breakage. do not do. Therefore, post-processes such as cooling, winding, and stretching can be smoothly performed.

As the metal short fibers 7 produced by the chatter vibration cutting method as shown in FIG. 4, the surface roughness is relatively rough,
When the cross-sectional shape is substantially polygonal, the entanglement of the fibers becomes strong, and since the surface area is large, the contact area with the molten polymer is widened, and the polygonal edge or ridge line 71 causes the fusion weight to increase. Since the united body is sheared and divided, the filtering and mixing properties can be improved.
