【発明の詳細な説明】
本発明は、合成繊維を製造する為の紡糸口金の
改良に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in spinnerets for producing synthetic fibers.
従来、溶融紡糸用の紡糸口金を作るには、第１

孔２の底に仝図ｃに示す如くポリマー吐出孔３を
貫通穿設して紡糸孔４を形成していた。 Conventionally, to make a spinneret for melt spinning, the first
A large number of polymer introduction holes 2 are formed in the spinneret plate 1 shown in FIG. 1 as shown in FIG. A spinning hole 4 was formed.

なる。 By the way, the polymer introduction hole 2 has a diameter of 2 to 4
mm and depth of 10 to 30 mm, the polymer introduction hole 2 is drilled by drilling, but the wall surface of this polymer introduction hole 2 is extremely rough as shown in Fig. 2a, so the molten polymer 5 is formed during spinning. As the spinning operation progresses, the molten polymer 5 adheres and grows and solidifies as shown in Figure b, making it impossible for the molten polymer 5 to flow out smoothly. The wall surface of such a polymer introduction hole 2 can be mirror-finished by polishing, etc.
As the number of polymer introduction holes 2 increases, the number of processing steps increases, resulting in an extremely expensive spinneret.
また、ポリマー導入孔２の壁面が鏡面であるガ
ラスのみで作られた紡糸口金があるが、取扱上割
れ易く、厚みを厚くすると背圧が上昇するなどの
欠点がある。 Further, there is a spinneret made only of glass in which the wall surface of the polymer introduction hole 2 has a mirror surface, but this has drawbacks such as being easily broken when handled and increasing the back pressure when the thickness is increased.
本発明は上記諸事情に鑑みなされたものであ
り、ポリマー導入孔の壁面が鏡面で溶融ポリマー
が円滑に流出し、安定して紡糸できる紡糸口金を
提供せんとするものである。 The present invention has been made in view of the above-mentioned circumstances, and it is an object of the present invention to provide a spinneret in which the wall surface of the polymer introduction hole is mirror-finished, allowing the molten polymer to flow out smoothly and capable of stable spinning.
本発明による紡糸口金は、予め穿設した貫通孔
を有する紡糸口金板の前記貫通孔に、別途製作し
た紡糸用ガラス細管が装着されて成るものであ
る。 The spinneret according to the present invention has a spinneret plate having a pre-drilled through hole, and a glass thin tube for spinning, which is separately produced, is attached to the through hole of the spinneret plate.
以下その詳細を第３図ａ〜ｄの製作工程に基い

である。 The details will be explained below based on the manufacturing process shown in FIGS. 3a to 3d. The third spinneret plate 1 shown in FIG.
As shown in Figure 3b, a large number of through-holes 6 with tapered tips are bored, and each through-hole 6 has a separately manufactured polymer introduction hole 2' followed by a polymer discharge hole 3' as shown in Figure 3c. Attach the glass thin tube 7 for spinning,
After that, the upper and lower ends of the spinning glass capillary tube 7 protruding from the upper and lower surfaces of the spinneret plate 1 were cut and removed as shown in FIG.

ることもない等の効果がある。 In the spinneret 8 of the present invention having such a structure, since the spinning hole consisting of the polymer introduction hole 2' and the polymer discharge hole 3' following it is constituted by the glass spinning tube 7, its wall surface is mirror-finished and The hole shape has a series of gently curved surfaces from the tip of the polymer introduction hole 2' to the polymer discharge hole 3'. Therefore, the molten polymer flows out smoothly without being subjected to resistance or stagnation, and can be stably spun. In addition, since the tip of the polymer discharge hole 3' is made of glass, it has poor wettability with the molten polymer, and therefore, the threads tend to come apart very easily. Furthermore, the spinneret 8 of the present invention does not have to worry about breaking during handling, unlike conventional spinnerets made only of glass, and there is no need to increase the thickness, so back pressure does not increase. .
