本発明は、紡糸口金の製造方法に関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a spinneret.
紡糸口金材料として使用されているタンタル材
は、ポリマー紡糸時の糸ばなれが極めて良好で、
デニールむらが生じにくいという良さがある。ま
た五酸化タンタル被膜というガラス質の材料面は
ポリマー紡糸時の抵抗が低くなることから紡糸圧
力が低い範囲で操業でき、従つて圧力による紡糸
口金の変形、歪量が少ないことから糸切れが生じ
にくいという良さがある。更に熱処理による材料
硬度の増加が可能なので、特にポリマー吐出孔の
部分の摩耗量が少ないという良さがある。 The tantalum material used as the spinneret material has extremely good yarn unraveling during polymer spinning.
It has the advantage that denier unevenness does not easily occur. In addition, the glassy material surface of the tantalum pentoxide coating has low resistance during polymer spinning, so it can be operated at a low spinning pressure.Therefore, the deformation and strain of the spinneret due to pressure is small, resulting in yarn breakage. It has the advantage of being difficult. Furthermore, since the hardness of the material can be increased by heat treatment, there is an advantage that the amount of wear, especially at the polymer discharge hole portion, is small.

めて高価な紡糸口金となる。 However, tantalum material is extremely expensive and requires extremely high purity as a spinneret material, so it is only used when the weight and thickness of the material is small, such as spinnerets for staple fibers such as acrylic and rayon produced by wet spinning. When using the melt spinning method where the spinning pressure is limited to 50Kg/cm 2 to 100Kg/cm 2 , the spinneret has a thickness of 10 to 20mm and a spinneret diameter of 100mm.
The spinneret is 200 mm, which is large in both weight and thickness, making it an extremely expensive spinneret.

The purpose is to provide a method.

５図に示す如く除去して紡糸口金１０を得る。 The method for manufacturing a spinneret according to the present invention will be explained below with reference to the drawings. As shown in FIG. 1, a spinneret material 1
A large number of polymer introduction holes 2 are drilled at regular intervals and polymer discharge holes 3 are preformed at the bottom of the holes. A trumpet-shaped opening 4 is provided at the bottom of the preformed polymer discharge hole 3. Next, as shown in FIG. 2, a disc-shaped tantalum chip 5 having approximately the same diameter as the polymer introduction hole 2 is inserted into the bottom of the polymer introduction hole 2. Next, this spinneret material 1 is inserted into a third hole corresponding to the polymer discharge hole 3 of the spinneret material 1.
As shown in the figure, the spinneret material 1 is placed on a base 7 having a concave portion on its upper surface, and the polymer discharge hole 3 and the concave portion 6 are aligned to fix the spinneret material 1 to the base 7. Thereafter, as shown in FIG. 4, the tantalum chip 5 is punched using a punch tool 8 to penetrate the polymer discharge hole 3, and the tantalum chip 5 is plastically deformed to form the bottom of the polymer introduction hole 2 and the polymer discharge hole. A tantalum material 5' is pressed against the inner wall surface of No. 3 for finishing shaping. At this time, a slight excess of the tantalum material 5' protrudes from the lower end opening of the polymer discharge hole 3, but this protrusion 9
escapes into the recess 6 of the base 7. Also punch tool 8
The tip also enters into the recess 6. Therefore, finishing shaping of the bottom of the polymer introduction hole 2 and the polymer discharge hole 3 by punching can be smoothly performed without any problem. Next, remove the spinneret material 1 from above the base 7,
At another location, the protrusion 9 of the tantalum material protruding from the lower end opening of the polymer discharge hole 3 is removed by grinding and polishing, as shown in FIG. 5, to obtain a spinneret 10.

行なうことができる。 The spinneret 10 made in this way has excellent characteristics as a spinneret material, namely, good yarn unraveling during polymer spinning, less denier unevenness, and less deformation and distortion of the spinneret due to spinning pressure. Tantalum material 5' has excellent properties such as being less prone to yarn breakage and reducing the amount of wear at the polymer discharge hole by increasing the hardness of the material through heat treatment. Since the spinneret 10 is pressed only at the necessary portions of the inner wall of the lower flap-shaped opening 4, the spinneret 10 can take full advantage of the above-mentioned characteristics even if the amount used is small. In addition, the tantalum material 5', which is pressure-welded only to the necessary parts of the inner walls of the bottom of the polymer introduction hole 2, the polymer discharge hole 3, and the tapered opening 4 below it, is connected to the tapered part of the bottom of the polymer introduction hole 2 and the polymer discharge hole. Since it is securely held with the flap-shaped opening 4 at the bottom of the hole 3 so as to prevent it from coming off vertically, it will not peel off and shift even if excessive spinning pressure is applied, so that the spinning operation can be carried out smoothly. can be done.
