本発明は口金装置内におけるポリマの異常滞留を防止し
た溶融紡糸用口金装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a melt-spinning die device that prevents abnormal retention of polymer within the die device.
従来の溶融紡糸用口金装置においては、ポリマ，が口金
装置内を通過して紡糸孔に至るまでの間に流動斑、温度
斑等の影響を受けて諸性質の変化をきたし、各紡糸孔に
おけるポリマの性質は相当に不均一であった。In conventional melt-spinning spinneret devices, various properties of the polymer change due to flow unevenness, temperature unevenness, etc. while passing through the spinneret device and reaching the spinning holes. The properties of the polymer were quite heterogeneous.
このような不均一のポリマをそのまま紡糸孔から吐出す
ると、繊度斑、糸曲がり、ドリップ等のトラブルを発生
するため、紡糸孔の直前においてポリマを混ぜ合わせる
特公昭４４−２２５２４に示されるような装置が提案さ
れた。If such non-uniform polymer is discharged as it is from the spinning hole, problems such as uneven fineness, yarn bending, and dripping will occur, so a device such as that shown in Japanese Patent Publication No. 44-22524 is used to mix the polymers just before the spinning hole. was proposed.
この装置は、第１図に示すように耐圧板１と口金板２と
の間に中心に絞り孔３を有する絞り板４を設けたもので
あり、ポリマは濾材５、濾材支持金網６、耐圧板１の細
孔７を経て、絞り板４の上面凹部８に送られ、絞り孔３
に集められた後絞り板４下面の凹部９によって導入孔１
０に供給され、紡糸孔１１から吐出されるのである。As shown in FIG. 1, this device is provided with a diaphragm plate 4 having a diaphragm hole 3 in the center between a pressure plate 1 and a cap plate 2. It passes through the fine hole 7 of the plate 1, is sent to the upper surface recess 8 of the aperture plate 4, and is sent to the aperture hole 3.
The concave portion 9 on the lower surface of the aperture plate 4 allows the introduction hole 1 to be
0 and is discharged from the spinning hole 11.
このような装置によれば、絞り孔３によってポリマを均
一に混ぜ合わせることができるが、口金板２の中央部は
口金装置の組立、分解の作業性を考慮して一般に紡糸孔
１１が穿設されていないため、異状滞留部１２が生じる
という欠点があり、この欠点は特に第２図に示すような
装置の場合著しい。According to such a device, the polymer can be mixed uniformly through the aperture hole 3, but a spinning hole 11 is generally drilled in the center of the spinneret plate 2 in consideration of ease of assembly and disassembly of the spinneret device. As a result, there is a disadvantage in that an abnormal stagnation portion 12 is formed, and this disadvantage is particularly noticeable in the case of the apparatus shown in FIG.
すなわち、第２図に示す装置は口金装置を多孔化する際
に生じる紡出糸条の冷却の不均一化を解消するため、冷
却風吹出装置１３を紡出糸条の中央部に設けたもので、
そのためには紡糸孔１１を円環状帯に分布して穿設した
口金板２を用いる必要がある。That is, the device shown in FIG. 2 is one in which a cooling air blowing device 13 is provided in the center of the spun yarn in order to eliminate uneven cooling of the spun yarn that occurs when the spinneret device is made porous. in,
For this purpose, it is necessary to use a spinneret plate 2 in which spinning holes 11 are distributed and drilled in an annular band.
しかるに、かかる口金板２を用いると、絞り孔３を流下
したポリマが凹部９内に広がる際に、紡糸孔１１までの
距離が長くなるため、絞り孔３の直下における異常滞留
１２が増大すると共に凹部９の外周部における異常滞留
１２′も増大するという欠点があった。However, when such a spinneret plate 2 is used, when the polymer flowing down the aperture hole 3 spreads into the recess 9, the distance to the spinning hole 11 becomes longer, which increases the abnormal retention 12 directly under the aperture hole 3. There is a drawback that the abnormal retention 12' at the outer periphery of the recess 9 also increases.
本発明の目的は上記従来装置の欠点である異常滞留を防
止し、糸曲がり、ドリップ等の少ない安定した紡糸状態
と繊度斑、品質斑の少ない均一な糸条とを得ることので
きる溶融紡糸用口金装置を提供することにある。The purpose of the present invention is to prevent abnormal retention, which is a drawback of the above-mentioned conventional apparatus, and to obtain a stable spinning state with less yarn bending, dripping, etc., and a uniform yarn with less fineness unevenness and quality unevenness. The purpose is to provide a cap device.

A plate is provided to form an annular slit between the two, and the upper end of the annular slit is enlarged to form a polymer collection section, and the inner and outer sweeps are carried out so that the polymer collection section is swept away by the flowing polymer. The surface forming the polymer collection section of the plate is inclined, and the lower end of the annular slit is enlarged to form a polymer distribution section, and the inner and outer sweeps are made such that the polymer distribution section is swept away by the flowing polymer. The present invention relates to a melt-spinning die device characterized in that a surface of a plate forming a polymer distribution section is inclined.

異状滞留を防止することができるのである。According to the device of the present invention, the annular slit allows polymers to be mixed uniformly and prevents abnormal accumulation at the center of the mouth plate.Moreover, the upper and lower ends of the annular slit are enlarged and tilted to sweep the polymer itself. The flow effect can prevent abnormal accumulation at the outer periphery of the polymer collecting section and the bollmer distributing section.

Abnormal accumulation at the outer periphery of the section 21 is prevented, and the lower end of the annular slit 20 is expanded to form a polymer distribution section 24, as well as the polymer distribution section 24 of the inner sweep plate 18 and the outer sweep plate 19. By slanting the surfaces 25 and 26, the polymer flowing down from the annular slit 20 can be distributed to the spinning hole 11 without causing abnormal retention.
