【発明の詳細な説明】 本発明は合成樹脂繊維の製造方法に関するものであ

の形状を有する。Due to their great strength and rigidity, synthetic resin fibers, especially fibers formed from oriented polymers, are often used, for example, as textile fiber reinforcing means for optical telecommunications cables and as fillers for synthetic resin composites. Has been done. The term "molecularly oriented" as used herein shall mean that the substance concerned includes anisotropic molecules having a preferred orientation. In molecularly oriented synthetic resin fibers, the polymer molecules are stretched, but the preferred orientation is in the longitudinal direction of the fiber. Generally, in unoriented synthetic resins, the polymer molecules have the shape of isotropic clusters or coils.

い。According to a known method for producing synthetic resin fibers, for example, as described in European Patent Application Publication No. 145745,
The molten polymer is extruded through a small opening and then the liquid filaments are guided through cooling means, where the polymer solidifies to form solid filaments. Due to the high temperature of the melt in the melting and extrusion processes, chemical decomposition is unavoidable.
しかし、他の合成樹脂繊維の製造方法が知られてお

程に要するエネルギーの観点から、溶剤の使用はしばし
ば望ましくない。However, other methods of making synthetic resin fibers are known, in which the fibers are spun from a polymer solution at relatively low temperatures. In the above process, the solvent is evaporated or otherwise the solution is introduced into the medium and the polymer solidifies in the medium. If the polymer has a high molecular weight, then only a limited number of suitable solvents are available. For example, the use of solvents is often undesirable in terms of environmental pollution, safety during use and energy required for the evaporation process.
本発明の目的は、重合体分子の化学分解がいかなる悪
影響をも有さないような低い温度で使用することができ
る合成樹脂繊維の製造方法を提供することにある。It is an object of the present invention to provide a method for producing synthetic resin fibers which can be used at low temperatures such that the chemical degradation of polymer molecules does not have any adverse effect.
本発明の他の目的は溶剤を使用する必要がない方法を

合物が、所望の繊維形状を出発物質に付与するまでは重
合しないことに注目すべきである。This object is achieved according to the invention by a process in which a starting material consisting of at least one oligomeric compound is extruded from a melt to form a liquid thread and then the starting material is polymerized by treatment with actinic radiation. Oligomer compounds have low melting points, i.e. low processing temperatures,
It also has a lower viscosity than the corresponding polymeric compounds. This is another advantage that oligomeric compounds can be extruded at lower pressure than the corresponding polymeric compounds. The oligomeric compound can be a monomeric compound or a compound consisting of some number of monomeric units. However, it should be noted that the compound does not polymerize until it imparts the desired fiber shape to the starting material.
出発物質の迅速な凝固が望まれるので、重合は熱処理

「化学線の照射」とは、光、特に、紫外線、X線、γ線

たはイオンを用いる照射を意味するものとする。Since rapid solidification of the starting material is desired, the polymerization is carried out by actinic radiation rather than heat treatment. Here, "irradiation with actinic radiation" means irradiation with light, in particular, ultraviolet rays, X-rays, γ-rays or irradiation with high-energy particles such as electrons or ions.

Stabilizers, co-reacting monomers and surface-active ingredients can be included.

The fibers are produced in the usual way, for example spun from a melt. In this way, the creep and relaxation of the stretched polymer molecules is hindered by the known method of fixing stretched conformations by cross-linking between polymer molecules. Such a crosslinking reaction is
It can be caused by irradiation with high-energy particles such as electrons.
本発明の目的は、著しく高い分子配向度を生ずる事実

繊維の製造方法を提供することにある。It is an object of the present invention to provide a process for the production of molecularly oriented synthetic resin fibers which makes it possible to obtain a product with a remarkably regular molecular structure and great strength due to the fact that it produces a remarkably high degree of molecular orientation.

る。The purpose is to extrude a starting material containing at least one oligomeric compound from a melt to form a liquid thread,
Then, when the starting material is treated with actinic rays to polymerize, the oligomer compound is oriented immediately after the extrusion step by causing the liquid thread to flow longitudinally, and then the starting material is oriented to form an oriented oligomer compound. Is achieved by a method of the invention characterized by polymerizing prior to the relaxation of

囲でのみ可能である。The present invention is based on the phenomenon established experimentally that in liquids having a relatively low viscosity, orientation can be carried out very effectively by means of longitudinal flow. Unpolymerized molecules are small enough to form ordered, almost crystalline structures, but in the case of polymers, especially where there are crosslinks between the molecules of the polymer, the structure is limited to a limited extent. Only possible.

操作において、繊維が強化され、架橋結合が形成され
る。In order to maintain the molecular orientation, the polymerization process needs to be carried out rapidly and at a sufficiently high rate, and for this reason actinic radiation is used to initiate the polymerization process. In this case, the actinic radiation is
It is not used to form crosslinks in the existing polymeric material, but to form a polymer. Another advantage of the method of the present invention is the effective use of actinic radiation when it is used simultaneously for polymer formation and for the formation of crosslinks between polymer molecules. In this case, it is not necessary to carry out another operation after the fibers have been formed, in which the fibers are reinforced and crosslinks are formed.
本発明の方法の他の利点は、規則正しい分子構造の結
果として、高分子物質中に著しく多くの架橋結合の形成
が可能であり、この結果として、ほとんどクリープを被
らない著しく強い繊維が得られることである。Another advantage of the method of the present invention is that, as a result of the ordered molecular structure, it is possible to form significantly more crosslinks in the polymeric material, which results in significantly stronger fibers that undergo almost no creep. That is.
多くの普通の単量体化合物は、本発明の方法の出発物

子が異方性である場合でさえ、配向させるのが困難であ
るためおよび小さい分子は著しく高い弛緩速度を有する
ため、即ち配向力が存在しなくなる場合未配向部分が迅
速に現われるためである。Many common monomeric compounds cannot be used as starting materials in the process of the present invention. The reason for this is, for example, that even if the small molecules are anisotropic, they are difficult to orient and because the small molecules have a significantly higher relaxation rate, i.e. when the orientation force is absent the unoriented parts are This is because it appears quickly.
本発明の方法の極めて有効な例において、使用するオ
リゴマー化合物と処理温度を、オリゴマー化合物がその
処理温度で液晶特性を示すように選定する。In a highly effective example of the method of the present invention, the oligomeric compound used and the treatment temperature are chosen such that the oligomeric compound exhibits liquid crystal properties at the treatment temperature.

る。この処置により、分子の弛緩時間が増し、硬化時間
はそれ程重大でない。In one example of the method of the invention using the dielectric anisotropy of a molecule, the orientation is increased by applying an electric or magnetic field. Depending on the orientation of the dipole moment, that is, whether the field is applied longitudinally or perpendicularly to the molecule, it is applied longitudinally or vertically to the fiber producing the field. This treatment increases the relaxation time of the molecule and the cure time is less critical.

Alternatively, it is a liquid crystal having a smectic group. Furthermore, it is possible to select fast-curing starting materials which consist of a mixture of oligomers, for example a mixture in which the polymerization reaction is the reaction of vinyl groups and thiol groups.

It is possible to use oligomeric compounds which consist of chains and whose acrylate-ester groups are attached to the chains via such flexible groups. A high degree of molecular orientation is possible because of unbranched chains and the presence of flexible, rigid chemical groups in the backbone of polymer molecules. Acrylate-
Ester groups allow high rates of polymerization and therefore these groups must have some degree of mobility. Polymer networks can be formed because there are at least two polymerized acrylate-ester groups in each molecule.
