【発明の詳細な説明】
本発明は、紡糸口金に係り、特に数万乃至数10
万という多数の紡糸孔を有するレーヨン、アクリ
ル等のステーブルフアイバー用の紡糸口金に関す
る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a spinneret, and particularly relates to a spinneret.
This invention relates to a spinneret for stable fibers of rayon, acrylic, etc., which has a large number of spinning holes of 1,000,000.
一般にレーヨン、アクリル等のステーブルフア
イバー用の第１図に示す如き皿形の紡糸口金１は
１万乃至30万個の多数の紡糸孔２が必要で、この
為紡糸口金１の直径300〜400mm程度の大きさとな
つている。 Generally, a dish-shaped spinneret 1 as shown in FIG. 1 for producing stable fibers such as rayon and acrylic requires a large number of spinning holes 2, from 10,000 to 300,000, and for this reason, the diameter of the spinneret 1 is 300 to 400 mm. It is about the same size.
ところで、斯かる紡糸口金１は、直限に比し厚
さが薄いので、耐圧性に劣り、通常の紡糸圧力
（５〜30Kg／cm2）の下では鎖線に示す如く紡糸口
金１の紡糸面が膨らむと共に胴部が下方に引き伸
ばされて径が縮小し、紡糸中切れが生じたり、糸
同志がくつついたりして、糸の品質が悪化すると
共に安定した紡糸作業ができなくなるものであ
る。 By the way, such a spinneret 1 has a thinner thickness than a straight spinneret, so it has poor pressure resistance, and under normal spinning pressure (5 to 30 kg/cm 2 ), the spinning surface of the spinneret 1 as shown by the chain line As the yarn swells, the body is stretched downward and the diameter is reduced, causing breakage during spinning or the yarns sticking together, which deteriorates the quality of the yarn and makes it impossible to perform stable spinning operations.
この為、紡糸口金１の厚みを厚くして耐圧性を
備える試みがなされている。 For this reason, attempts have been made to increase the thickness of the spinneret 1 to provide pressure resistance.
然し乍ら、紡糸口金１の厚みを厚くすること
は、パンチ加工による穿孔の場合、数回に分けて
穿孔しなければ、パンチ工具に折損が生じる。ま
た数回に分けて穿孔しても、パンチ加工時歪が発
生し、紡糸口金１の紡糸面は凹凸或いは凹形に変
形し、紡糸時の糸切れは同様に起る。 However, increasing the thickness of the spinneret 1 means that if the holes are punched, the punch tool will break if the holes are not punched several times. Furthermore, even if the holes are punched several times, distortion occurs during the punching process, the spinning surface of the spinneret 1 is deformed into an uneven or concave shape, and yarn breakage also occurs during spinning.
一方、切削加工による穿孔も考えられるが、こ
の場合、紡糸孔の壁面が粗くなり、ポリマーの流
れが不安定になる。 On the other hand, drilling may be performed by cutting, but in this case, the wall surface of the spinning hole becomes rough and the flow of the polymer becomes unstable.
以上いずれの場合に於いても穿孔工程は非常に
長くなり、コストの高い紡糸口金となつている。 In any of the above cases, the perforation process becomes very long, resulting in an expensive spinneret.
本発明は、斯かる諸事情に鑑みなされたもので
あり、耐圧性に優れて良好な糸を安定して紡糸で
き、また加工工数が少くて精度良く安価にしかも
能率良く製作できるレーヨン、アクリル等のステ
ーブルフアイバーの紡糸口金を提供せんとするも
のである。 The present invention has been made in view of the above circumstances, and has been developed to produce rayon, acrylic, etc., which have excellent pressure resistance, can stably spin good quality yarns, and can be produced efficiently, accurately, inexpensively, and with fewer processing steps. The present invention aims to provide a stable fiber spinneret.
以下本発明による紡糸口金の実施例を図によつ
て説明すると、第２図に示す如く紡糸面に多数の
微細な紡糸孔２を有する皿形の紡糸口金１に於い
て、その胴部３の内周面に補強リング４を嵌合固
定して成るものである。 Hereinafter, an embodiment of the spinneret according to the present invention will be explained with reference to the drawings. As shown in FIG. A reinforcing ring 4 is fitted and fixed to the inner peripheral surface.
補強リング４は上下方向の厚みが等しいもので
も良いが、図示の如く該リング４の内周面にテー
パ４ａを付して下側より上側に向つて次第に厚さ
を厚くしたものの方が、紡糸面の紡糸孔２を塞ぐ

が無いので都合が良い。また補強リング４の材料
としては機械的な剛性に優れ、硬度が高く、耐食
性、耐摩耗性に優れた材料、例えばステンレス
鋼、超硬材セラミツクス、高張力鋼等が好まし
い。 The reinforcing ring 4 may have the same thickness in the vertical direction, but it is better to have a taper 4a on the inner peripheral surface of the ring 4 so that the thickness gradually increases from the bottom to the top as shown in the figure. This is convenient because the spinning holes 2 on the surface are not blocked and therefore the number of spinning holes 2 is not reduced. The reinforcing ring 4 is preferably made of a material that has excellent mechanical rigidity, high hardness, corrosion resistance, and wear resistance, such as stainless steel, cemented carbide ceramics, and high-strength steel.
第３図に示す実施例は、紡糸面に多数の微細な
紡糸孔２を有するドーナツ形の紡糸口金５に於い
て、その胴部６の外側内周面と内側内周面に夫々
大小の補強リング７，８を嵌合固定して成るもの
である。 In the embodiment shown in FIG. 3, in a donut-shaped spinneret 5 having a large number of fine spinning holes 2 on the spinning surface, reinforcements of different sizes are applied to the outer and inner circumferential surfaces of the body 6. It is made by fitting and fixing rings 7 and 8.
この場合の補強リング７，８も上下方向の厚み
が等しくとも良いが、図示の如くリング７の内周
面とリング８の外周面に夫々テーパ７ａ，８ａを
付して下側より上側に向つて次第に厚さを厚くし
た方が紡糸孔２の数を減少することが無いので都
合が良い。 In this case, the reinforcing rings 7 and 8 may also have the same thickness in the vertical direction, but as shown in the figure, the inner peripheral surface of the ring 7 and the outer peripheral surface of the ring 8 are tapered 7a and 8a, respectively, so that the thickness increases from the lower side to the upper side. It is convenient to gradually increase the thickness since the number of spinning holes 2 does not decrease.
以上の如く本発明の紡糸口金は、胴部内周面に

紡糸面が緊張状態となるので、通常の紡糸圧力で
は紡糸面が膨らむことが無く、従つて胴部が下方
に引き伸ばされて径が縮小するようなことが無い
ものである。 As described above, the spinneret of the present invention has a reinforcing ring fitted and fixed to the inner peripheral surface of the body, so even if the thickness of the spinneret is thin, the normal spinning pressure (5 to 30 kg/cm 2 ) can be maintained.
Under these conditions, the spinning surface will not swell, and the body will not be stretched downward and the diameter will not be reduced. In other words, the periphery of the body and the spinning surface are held down by the reinforcing ring, and the spinning surface becomes under tension, similar to fitting a hoop into a tub, so the spinning surface does not swell under normal spinning pressure. Therefore, there is no possibility that the trunk portion will be stretched downward and the diameter will be reduced.
かくして紡糸中、糸切れが生じたり、糸同志が
くつついたりすることが無く、糸の品質を維持で
きると共に安定した紡糸作業ができる。 In this way, during spinning, yarn breakage does not occur and yarns do not stick together, and the quality of the yarn can be maintained and a stable spinning operation can be performed.
また本発明の紡糸口金は、厚みを厚くする必要

いは凹形に変形することが無く、糸切れすること
も無い。 In addition, since the spinneret of the present invention does not need to be thick, the number of man-hours required for forming the spinning hole is small, and the punch tool does not break, and there is almost no distortion during punching. The spinning surface does not become uneven or concave, and the yarn does not break.

る等の効果がある。 As detailed above, the spinneret of the present invention has excellent pressure resistance, and the spinning surface does not swell during spinning and the diameter does not decrease due to the body being stretched downward.
Able to stably spin good yarn. Further, since the spinneret of the present invention has a thin spinning surface, it has the advantage that the number of man-hours required for processing the spinning hole is small, and it can be manufactured accurately, inexpensively, and efficiently.
