「産業上の利用分野」
本発明は、押出し成型機による細糸の製造方法及び該成
型機におけるダイス又はＴダイス金型装置に関し、殊に
細糸（モノフィラメント）を延伸等の二次処理を必要と
することなく、成型により直接得ることのできる手段に
関するものである。Detailed Description of the Invention "Industrial Application Field" The present invention relates to a method for producing fine yarn using an extrusion molding machine and a die or T-die mold device in the molding machine, and particularly relates to a method for producing fine yarn using an extrusion molding machine, and a die or T-die mold device for the molding machine, and particularly relates to a method for producing fine yarn using an extrusion molding machine. The present invention relates to a means that can be obtained directly by molding without the need for secondary processing such as.
「従来の技術」
この種モノフィラメントの細糸の用途は、初期において
、釣糸、網、ブラシ用剛毛などに限られていたが、現在
ではロープ、漁網、工業用織物、家具用織物、などの産
業用資材として、多用途に亘り、使用されている。``Prior art'' In the early days, the use of this type of monofilament thin thread was limited to fishing lines, nets, bristles for brushes, etc., but now it is used in industrial applications such as ropes, fishing nets, industrial textiles, furniture textiles, etc. It is used for a variety of purposes as a material.
そして、この種細糸は押出し成型機の先端に２０個乃至

レートを取付け、そこから押出された糸を冷却し、延伸
工程によって、糸の太さを調整だ最終的な糸の太さに比
べて、押出し時の糸の太さは、５倍乃至４０倍程度太く
て良いことから、比較的容易に製造されていた。Then, this kind of fine yarn is produced by installing a die plate with an extrusion port consisting of 20 to 100 small holes at the tip of the extrusion molding machine, cooling the yarn extruded from there, and drawing it. Compared to the final thickness of the yarn, the thickness of the yarn at the time of extrusion can be about 5 to 40 times thicker, making it relatively easy to manufacture.
ところで、この種製品の用途によっては、押出しと同時

型法における制約はモノフィラメント製法の延伸工程を
用いないために、製品形状の糸の太さが細くなると前記
押出し口の金型を製作する上で、極めて困難なことであ
る。Incidentally, depending on the use of this type of product, it may be advantageous to perform molding at the same time as extrusion. However, a limitation of this simultaneous molding method is that it does not use the drawing step of the monofilament manufacturing method, and therefore, when the thickness of the thread in the product shape becomes thinner, it becomes extremely difficult to manufacture the mold for the extrusion port.

のことがら、従来装置では、前記プレートに大径の内側
穴もしくは漏斗状の内側穴を穿ち、その中心に細径の外
側孔を穿つ手段が採られていた。That is, the die or T-die mold used in an extrusion molding machine usually requires drilling a large number of extrusion holes in a plate made of iron, stainless steel, or special steel with a wall thickness of 201% to 3011%. Therefore, it is extremely difficult to form a small diameter straight hole through the wall thickness. For this reason, in conventional devices, a method has been adopted in which a large-diameter inner hole or a funnel-shaped inner hole is bored in the plate, and a small-diameter outer hole is bored in the center of the inner hole.

従って、斯かる加熱分解が生じたダイスは一旦稼動中止
した上で、分解清掃を行わなければならず、そのだめの
作業及び時間に非常に手間がかかる。即ち、先の熱分解
は塩化ビニール樹脂を用いえると熱分解が顕著になる。``Problems to be Solved by the Invention'' However, according to the above-mentioned mold processing means, the volume of the large-diameter inner hole that maintains the resin extrusion temperature at a high temperature during the molding operation is large, so that the core part The resin may not be extruded uniformly and some internal convection may occur, resulting in some resin remaining in the part for a long time and continuing to be heated. Then, thermal decomposition occurs in this retained resin, resulting in a molded product having properties different from the resin's original properties. or,
Once the decomposition begins at the relevant part, a chain reaction occurs,
All molded products that come out of the extrusion port in that part are of a decomposed nature. Moreover, this decomposition reaction cannot be stopped even if the resin molding temperature is lowered to the low limit temperature that allows molding. Therefore, the die in which such thermal decomposition has occurred must be disassembled and cleaned once the die has undergone such thermal decomposition. This requires a lot of effort and time. That is, the thermal decomposition described above becomes more pronounced when vinyl chloride resin can be used.
同様に塩化ビニリデン樹脂の場合は、１８０℃で熱分解
が始まシ、１９０℃域で熱分解が顕著となる。Similarly, in the case of vinylidene chloride resin, thermal decomposition begins at 180°C and becomes noticeable in the 190°C range.
同じく塩化ポリプロピレン樹脂を使用した場合では１８
０℃乃至１９０℃で熱分解を起こしてしまう。Similarly, when using chlorinated polypropylene resin, it is 18
Thermal decomposition occurs at temperatures between 0°C and 190°C.
そして、酢酸ビニール樹脂を用いた場合には２００℃で
熱分解を起こす。When vinyl acetate resin is used, thermal decomposition occurs at 200°C.
このように、加工成型温度と熱分解温度とが近似してい
るために、成型温度制御及びその管理が極めて難かしく
、在住にして前記分解反応が発生する慣れがある。As described above, since the processing and molding temperature and the thermal decomposition temperature are close to each other, it is extremely difficult to control and manage the molding temperature, and people who live here are accustomed to the occurrence of the decomposition reaction.
そのだめの解決手段としては、ダイス内での樹脂の流れ
を良くしてやることが必須条件であり、ダイス内での樹
脂滞留を極力防止する必要がある。As a solution to this problem, it is essential to improve the flow of the resin within the die, and it is necessary to prevent the resin from stagnation within the die as much as possible.

樹脂質りができない。"Function" By the pressurizing operation of the molding machine, the resin that reaches the die plate is extruded from the extrusion holes in the die and is molded into a monofilament. At this time, since the extrusion hole is composed of a straight hole of approximately the same diameter that passes through the die plate, the inner opening (resin injection side) and the outer opening (
Since the resin pressure between the resin extrusion side (resin extrusion side) acts evenly and uniformly extrudes the resin that has reached the core, there is no resin buildup in the core.

It is sent out towards the head part 3, guided to the die 4 attached to the head part 3, and is guided through a large number of extrusion holes 5 installed in the die 4.
The molded threads 6, 6, and so on are extruded from the threads 6 and 5, and these threads are passed through the entire cooling water tank 7 and wound up. In addition, 8 is a die heater, and each part of the processing process, for example,

Due to the pressurizing force at this time, the extrusion hole 5 is formed in a shape that is thicker than the diameter of the extrusion hole 5. For example, a monofilament yarn extruded from an extrusion hole 5 having a diameter of 1 diameter is formed to have an outer diameter of 1.1 to 1.2 diameters. Therefore, when it is desired to mold a thin thread having an outer diameter of 0.5 mm, the extrusion hole 5 is configured to have an inner diameter of at least 0.4 mm to 0.35 mm.

如く、その外形を円錐台形状に構成しても良い。The cartridge body 9 is formed with a center hole at the time of its formation, and is configured so that the center hole becomes the intended small diameter extruded hole 5 due to the shrinkage effect of the ceramic during sintering. The center hole can be formed by passing a thread made of a flexible material such as a cotton thread of a predetermined thickness during molding and burning it out during sintering, or by performing a primary sintering treatment at a low temperature after molding. In this case, the central hole is formed using a drill or the like in a state where the material is stable in shape but still has low hardness, and then complete sintering is performed at high temperature. The cartridge body 10 may have a truncated conical outer shape as shown in the third figure.

罹めて実用的なるものである。"Effects of the Invention" As described above, according to the method of the present invention, the extrusion holes arranged in the die or T-die are formed through straight holes of approximately the same shape across the inner and outer surfaces of the die plate, so that the molded resin in the extrusion holes is formed. This makes it possible to stably mold a small diameter monofilament thread by preventing the accumulation of resin in the armpit and by visiting the thermal decomposition reaction of the resin in the armpit. By using a cylindrical cartridge body made of a sintered body, it is possible to form small diameter extrusion holes by taking advantage of the shrinkage of the material during sintering. It is easy and can be replaced later. Furthermore, the extrusion hole may be formed by using a small-diameter metal tube processed by drawing treatment, or the metal diameter tube may be formed integrally with the ceramic sintered body. The apparatus of the present invention is very practical, as it can homogeneously mass-produce the intended narrow-diameter straight structures.
