本発明は、極細の糸を紡糸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 an improvement in a spinneret for spinning ultrafine yarn.
従来、極細の糸を紡糸するには、極細の紡糸液
吐出孔を有する紡糸口金を用いて紡糸するか、又
は外周を他の成分で被い紡糸延伸後その糸の外周
の成分を溶している。 Conventionally, in order to spin ultra-fine yarn, the yarn is spun using a spinneret with an ultra-fine spinning solution discharge hole, or the outer periphery of the yarn is covered with other components, and after spinning and drawing, the components on the outer periphery of the yarn are dissolved. There is.
ところで、極細の紡糸液吐出孔を有する紡糸口
金は、0.01mm以下のパンチ工具を作れないこと
から0.01mm以下の紡糸液吐出孔を有する紡糸口
金を作ることができないし、また極細のパンチ工
具は折損、屈曲、摩耗等が生じる為、紡糸液吐出
孔の精度が悪いものであり、さらに紡糸液吐出孔
の長さが長くとることができず、例えば紡糸液吐
出孔が孔径が0.01の場合、長さは0.01mm前後し
かとることができず、甚だ短いので、紡糸時紡糸
液を十分拘束できない為、紡出糸にデニールむら
が生じるものである。 By the way, it is not possible to make a spinneret with a spinning solution discharge hole of 0.01 mm or less because a spinneret with an ultra-fine spinning solution discharge hole cannot make a punch tool of 0.01 mm or less, The precision of the spinning solution discharge hole is poor because breakage, bending, abrasion, etc. occur, and the length of the spinning solution discharge hole cannot be made long. For example, if the spinning solution discharge hole has a hole diameter of 0.01, The length can only be around 0.01 mm, which is extremely short, and the spinning solution cannot be sufficiently restrained during spinning, resulting in uneven denier in the spun yarn.
また加工上の問題点以外に直径0.03mm以下の孔
径を有する紡糸口金の場合は、原液中の不純物、
異物などで孔づまりが発生することが多くなる。 In addition to processing problems, when using a spinneret with a hole diameter of 0.03 mm or less, impurities in the stock solution,
Hole clogging often occurs due to foreign objects.
本発明はかかる問題点を解消すべくなされたも
のであり、極細の糸を簡単に紡糸することができ
且つ所要の極細度合の糸を紡糸することができ、
しかも構造簡単で製作容易な紡糸口金を提供せん
とするものである。 The present invention was made to solve these problems, and it is possible to easily spin an ultra-fine yarn, and to spin a yarn with a required degree of ultra-fineness.
Moreover, it is an object of the present invention to provide a spinneret that has a simple structure and is easy to manufacture.

In the spinneret plate 4 having a large number of spinning holes 3, as shown in FIG. Spinning liquid guide rods 9, which are provided at intervals and have a small diameter middle part 7 shaped like a column and a lower part 8 shaped like a cone with a sharp tip, are fitted into each spinning hole 3 as shown in FIG. The upper part 5 is fixed to the large diameter upper part of the spinning solution introduction hole 1, and the middle high part 7 is arranged concentrically to form an annular passage 10 at the small diameter lower part of the spinning solution introduction hole 1 and the upper part of the spinning solution discharge hole 2. , the lower part 8 projects downward from the discharge surface 11 through the spinning solution discharge hole 2.

極細糸が紡糸される。 According to the spinneret 12 of the present invention having such a structure,
The spinning solution enters the annular passage 10 through each spinning solution inlet hole 6 provided in the circumferential direction of the large-diameter upper part 5 of the spinning solution guide rod 9 that is fitted and fixed in each spinning hole 3 . The spinning solution flows from the tip along the outer periphery of the conical lower part of the spinning solution guide rod 9, and is pulled out from the sharp tip to spin an ultrafine yarn.

By adjusting the area of the sharp tip of, for example, as shown in FIGS. 4a to 4c, or by adjusting the taper angle of the spinning solution guide rod 9, the degree of fineness of the ultrafine yarn to be spun can be adjusted. By using a spinneret 12 in which a spinning solution guide rod 9 with a required tip area and taper angle is set in advance, an ultra-fine yarn with a required degree of ultra-fineness can be obtained.
