アミド未延伸物及びその製造方法に関するものである。Detailed Description of the Invention (Industrial Field of Application) The present invention relates to an undrawn high-viscosity aliphatic polyamide and a method for producing the same, and particularly to an undrawn high-viscosity aliphatic polyamide with excellent undrawn properties and the production thereof. It is about the method.

いった問題を有している。たとえ相対粘度が４．０以上
の脂肪族ポリアミド未延伸物が得られても、延伸性に問
題があり、延伸が極めて困難であるのが実情である。(Conventional technology) High molecular weight polymers to obtain high strength, high modulus fibers,
That is, it is known that the use of polymers with high relative viscosity is effective, but aliphatic polyamides with relative viscosity of 4.0 or more are unstable when melt-spun due to a significant increase in the melt viscosity of the polymer. However, there is a problem in that spinning cannot be carried out automatically. Even if an unstretched aliphatic polyamide with a relative viscosity of 4.0 or higher is obtained, the actual situation is that there is a problem with stretchability and stretching is extremely difficult.
ましてや相対粘度が７．０程度以上のポリマーでは、溶
融紡出を行なうことすら困難である。Furthermore, it is difficult to even perform melt spinning on a polymer having a relative viscosity of about 7.0 or more.

おいては、ポリマーの溶解及び溶剤の回収などの設備が
必要となり溶融紡糸に比べてコスト的に不利となる。Regarding the method of spinning high viscosity aliphatic polyamide,
For example, solution spinning using a solvent such as formic acid (U.S. Pat. Nos. 4.263.187 and 4.379.773)
etc. are known. However, such @liquid spinning method requires equipment for dissolving the polymer and recovering the solvent, which is disadvantageous in terms of cost compared to melt spinning.

ど種々の問題を存していた。On the other hand, it is also possible to perform melt spinning by installing pressure-resistant equipment that can withstand increases in melt viscosity, but in this case,
The cost of pressure-resistant equipment is considerably higher than that of conventional equipment, and it is not possible to wind up the discharged yarn at a high speed. Furthermore, when drawing the spun yarn obtained after spinning using a high molecular weight polymer, for example, the stress during drawing increases significantly due to the increase in entanglement of molecular chains as the molecular weight increases. However, there were various problems such as the impossibility of high-magnification stretching.

くはε−カプロラクタムを用いるのがよい。The plasticizer used in the present invention may be any additive as long as it facilitates plastic deformation at the spinning temperature, but preferably it is a plasticizer for aliphatic polyamides such as sebacic acid, adipic acid, hexane, etc. It is preferable to use methylene diamine alone or a mixture thereof, more preferably a cyclic lactam such as α-pyrrolidone, α-piperidone, caprolactam, etc. alone or a mixture thereof, particularly preferably ε-caprolactam.

If it is less than 8 parts by weight, stretching becomes extremely difficult, while if it is more than 45 parts by weight, it will cause breakage during stretching, which is not preferable.

、固相重合を促進する方法などをあげることができる。Examples of methods for obtaining high-viscosity aliphatic polyamides include solid-phase polymerization of aliphatic polyamides having a relative viscosity of 2.0 to 3.0 in an inert gas at a temperature of 160°C or higher and lower than the melting point of the aliphatic polyamide; An example of this method is to add a phosphorus compound such as orthophosphoric acid as a catalyst during the solid phase polymerization to accelerate the solid phase polymerization.
次に製造方法について説明する。Next, the manufacturing method will be explained.

は７．０以上のポリアミドを用いて溶融押出しする。本
発明では溶融押出しに際し、溶融ポリマーが紡出口金に
到達する迄の間に、可塑剤を添加することが極めて重要
である。According to the present invention, the above polyamide having a relative viscosity of 4.0 or more, preferably 7.0 or more is used for melt extrusion. In the present invention, during melt extrusion, it is extremely important to add a plasticizer before the molten polymer reaches the spinneret.
本発明における高粘度脂肪族ポリアミドは、相対粘度が
４．０以上、好ましくは７．０以上がよい。The high viscosity aliphatic polyamide in the present invention has a relative viscosity of 4.0 or more, preferably 7.0 or more.
相対粘度が４．０よりも小さい脂肪族ポリアミドを用い
た場合には溶融粘度が低すぎて紡出状態が不安定になり
、且つ最終的に得られる延伸物の高強力高弾性率化が達
成されなくなるので好ましくない。If an aliphatic polyamide with a relative viscosity of less than 4.0 is used, the melt viscosity will be too low and the spinning state will become unstable, and the final drawn product will have high strength and high elastic modulus. This is not desirable because it will no longer be used.

るザイドフィード型の方法などを用いることができる。The amount of plasticizer added must be 8 parts by weight or more and 45 parts by weight or less. More preferably 20 parts by weight or more 40
It is desirable that the content be within the range of parts by weight or less. Here, if the amount of plasticizer is less than 8 parts by weight, the melt viscosity of the aliphatic polyamide will not be reduced sufficiently, and the melting pressure will increase significantly.
Problems arise in that stable spinning cannot be performed and high-speed winding is not possible, and furthermore, the drawability of the obtained undrawn product is significantly reduced, which is not preferable. In addition, if the amount added is 45 parts by weight or more, this method is undesirable because it causes disadvantages such as an extreme decrease in melt viscosity and frequent polymer breakage due to concentrated discharge of plasticizer. For example, when a polymer chip and a plasticizer are simply mixed and supplied, or when extruding molten aliphatic polyamide using a screw, a separate supply line is used from the flow channel wall of the molten polyamide. A so-called Zydefeed method can be used, in which a plasticizer is supplied and mixed with +8 melted polyamide.

延伸物が提供される。The conditions for melt spinning high viscosity aliphatic polyamide may be normal conditions, for example, the spinning temperature is about 240 to 300°C,
The spinning speed is 10 to 800 m/min, preferably 20 to 60 m/min.
Approximately 0 m/min is preferable. The unstretched product obtained in this way is an aliphatic polyamide with a relative viscosity of 4.0 or more, and is made with 8 parts by weight or more and 45 parts by weight or less of a plasticizer, and has extremely excellent stretchability, high strength, and high elastic modulus. An unstretched product suitable for obtaining a stretched product is provided.

向上に寄与していると推定しでいる。The unstretched product obtained by the present invention has extremely high stretchability due to the inclusion of a plasticizer, and it is clear that the plasticizer content plays a major role in making the aliphatic polyamide highly oriented and improving its physical properties. be. The dispersion state of the plasticizer, interaction with the aliphatic polyamide, etc. are not clear at present, but it is presumed that they contribute to improving the molecular mobility of the plasticizer and aliphatic polyamide molecular chains.
