（産業上の利用分野）
本発明は、主として湿式紡糸法に於いて用いる紡糸口金
の改良に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates primarily to improvements in spinnerets used in wet spinning methods.
（従来の技術）
従来より湿式紡糸法に用いられている一般的な紡糸口金

チで約３万個穿設されている。(Prior Art) As shown in FIG. 3, a general spinneret conventionally used in a wet spinning method has a dish-shaped longitudinal section with a flange 1 on the outer periphery. is external size 12
Approximately 30,000 discharge holes 3 with a diameter of 0.06 mm are drilled at a pitch of 0.5 μl per 0 m.

ところで、湿式紡糸法の場合、紡糸圧力は通常１０ｋｇ
／ｃｊ前後であるが、高い時には１００〜２００ ｋｇ
／ｄにも達し、前記紡糸口金２、は第４図に示す如く、
吐出面４が球面状に下方に膨出するので、紡糸口金２の
中央部と外周部での凝固条件が異なったり、又特に外周
部付近では糸同士のくっつきが生じるなどの欠点がある
。この為、紡糸口金２の板厚を厚くすることが考えられ

定すると、紡糸口金２の直径が１２０ｆｌの場合には前
記の如く吐出面４を湾曲させない為に、板厚は少なくと
も２０ｍｍ程度必要とする。(Problem to be solved by the invention) By the way, in the case of wet spinning method, the spinning pressure is usually 10 kg.
/cj, but at high times it weighs 100-200 kg
/d, and the spinneret 2, as shown in FIG.
Since the discharge surface 4 bulges downward in a spherical shape, there are disadvantages such as different coagulation conditions between the center and the outer periphery of the spinneret 2, and yarns sticking together especially near the outer periphery. For this reason, it is possible to increase the thickness of the spinneret 2, but assuming that the spinning pressure reaches 200 kg/-, if the diameter of the spinneret 2 is 120 fl, the discharge surface 4 should be increased as described above. To prevent bending, the plate thickness must be at least 20 mm.
然し乍ら、板厚２０龍程度の紡糸口金に数万個の吐出孔

費が高く、紡糸孔以外の部分に高価な材料が使用されて
、無駄が多い。However, it is technically very difficult to drill tens of thousands of discharge holes in a spinneret with a plate thickness of about 20 mm. This is because, for example, assuming that 20,000 spinning holes are drilled in a spinneret with an outer diameter of 120 m, the hole diameter is approximately 0.5 mm and the depth is 1 mm.
9. A blind raw solution introduction hole with a spinning hole spacing of 0.71m is drilled, and then a discharge hole is drilled through the tip of the hole, making it difficult to achieve dimensional accuracy and making it very difficult in terms of processing technology. It's a conflict =. In addition, the spinneret is generally made of Au-Pt alloy,
Since the Au-Pt-Rh alloy or Ta is used, the material cost is high, and expensive materials are used for parts other than the spinning holes, resulting in a lot of waste.
