る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electrospinning apparatus. The purpose is to provide a spinning device for obtaining fibers with controlled orientation by influencing the molecular orientation of the spun yarn using an electric field.

の乱れは、従来の未延伸糸を延伸して得られた繊維より
も大きくなることがわかってきた。Conventionally, in order to produce man-made fibers, a method has generally been adopted in which first, an undrawn yarn in which the molecular orientation has not progressed very much is drawn using a single spinning material, and then subjected to heat treatment for orientation and crystallization. In recent years, a method has been developed in which a partially oriented yarn (poy) in which one molecule is oriented to some degree is obtained by spinning at a relatively high spinning speed of 3000 to 4000 m/min, and then a slight stretching and false twisting are performed at the same time. (POY-DTY processing method) is beginning to be implemented. In order to reach even higher Kl, ultrahigh-speed spinning is being studied to obtain highly oriented yarns in one step without drawing. However, in this method, although the overall orientation of the molecules reaches a considerable level, the disorder of the molecules in the amorphous region is greater than in the fiber obtained by drawing conventional undrawn yarn. I've come to understand that.

７頁（１９８２））。On the other hand, the so-called zone drawing method, in which fibers obtained by conventional spinning methods are rapidly heated and cooled while applying high tension, and zone heat treatment, in which the fibers are subsequently heat-treated while applying high tension, are used to stretch the polymer. There is a way of thinking to obtain high elastic modulus and high strength fibers consisting of button crystal structure (for example, Pa, Journal of Japanese Society, Vol. 38, No. 6, No. 25).

極めて重要な技術となつ【きている。However, in this method, the molten polymer stream is cooled and converted into fibers 16I, and not only is it not an energy-saving method in that it is heated and cooled again, but also the fibers obtained by such zone drawing and zone heat treatment methods are One limitation is that the physical properties of spun fibers depend on the orientation of the raw fibers at the initial spinning stage.5 Therefore, controlling the molecular orientation of spun yarns has become an extremely important technology. ing.

困難である。On the other hand, research has also been conducted in which the spinneret is used as one electrode, a counter electrode is provided below the spinneret, and a high voltage is applied between them for spinning (for example, Journal of Polymer Science, Polymer Physics Edition (J, Polym. S
et, I'olym, Phys, Ed, + vol. 19, p. 909 (1981)). This method applies an electric field to the yarn being spun during spinning, but since a voltage is applied between the spinneret and its opposite electrode, a complicated structure is required to insulate it from the spinning puncture body. Not only is this method unsuitable for industrial implementation, but it also causes a large amount of molecular transport immediately after spinning, making it difficult to control the molecular orientation of the spun yarn.

出し、本発明に到達した。The present inventors tried to be frugal with regard to the device that controls molecular orientation by applying an electric field to the spun yarn, and as a result, the device was simplified by providing the electric field generating device separately from the spinneret. Furthermore, the present invention was achieved by discovering that the molecular orientation can be easily controlled.

以下、本発明を図面により説明する。Hereinafter, the present invention will be explained with reference to the drawings.

ましい。FIG. 1 shows an example of the apparatus of the present invention used for melt spinning, in which 1 is a spinneret or an electric field generating device, 3.
3' is a take-up godet roller, and 4 is a draining device. The yarn Y melted and discharged from the spinneret is taken off at a constant spinning speed by a take-up godet roller 3.3' and wound onto a winding device 4. The spun yarn YK is made almost parallel by an electric field generating device 2 installed directly under the spinneret l.
The chamber 7 formed by the electrode 5.5' and the insulator 6 contains:
It is filled with gas to prevent corona discharge. As the gas for preventing corona discharge, sulfur hexafluoride, nitrogen, etc. are used, but in the case of low voltage, air may also be used. 8 is an inlet for a gas for preventing corona discharge, and 9 is a DC power source. The electrode 5.5' typically has a thread passageway 10.1 in its center.
A disk-shaped piece with 0′ crossed is used, and its material is copper,
Aluminum, aluminum, stainless steel, etc. are preferable, especially those containing impurities! The one with the least 11° angle is better. Electrode 5.5'
It is preferable that the shape is as flat as possible so as not to cause local electric game concentration since pressure is applied to the height 7, but it may be donut-shaped, hollow cylindrical shape, or hollow cone-like shape depending on the case. In order to make the strength of the electric field applied to the spun yarn YK as thick as possible, the yarn Φ path l0110' is desirably made as small as possible within a range where the spun yarn Y does not come into contact with it.

置に設けることができる。It is necessary to provide it separately from the electric field generator or the spinneret 1. If the spinneret is used as one electrode and a voltage is applied between it and the opposite electrode, an extremely complicated structure will be required to insulate the spinneret, which is not suitable for industrial implementation. In addition, in such devices, the electric field is applied immediately after spinning when the molecules are in a state of extremely strong motion, so even if the molecules are once oriented, they return to the disordered state, making it difficult to control the orientation of the spun yarn. It becomes difficult to do so. Until the solidification of the spun yarn lead Y is completed, that is, the crystallization speed of the spun yarn is sufficiently slow and the fiber is thinned at high temperature. The region where the phenomenon is progressing is most preferable, but it is not particularly necessary to place it in a stiff position, and it can be provided at any position between the spinneret 1 and the winding device 40.

It is important to apply the electric field while the temperature of Y is high and the molecules are easily mobile. In the case of melt spinning, it is preferable to provide 11 field generators at a distance of 60 to 150 tM from the spinneret 1. Note that the winding device in the present invention is not limited to a winder, but also includes bucket devices such as cans and nets.

同様である。The apparatus of the present invention can be applied not only to melt spinning but also to dry spinning. In both dry spinning and wet spinning, the electric field generating device should be installed at a point where the solidification of the spun yarn is completed, that is, when the number of residual solvents coexisting with the spun yarn is 5 or more, The region where the thinning phenomenon is progressing (at a distance of 1 to 2 m from the spinneret) is most preferable, but it is not particularly limited to this location, as in the case of melt spinning.

意に選択使用することができる。The electric field generating device is straddled so that the direction of the lines of electric force generated is substantially parallel to the spun yarn. Here, "substantially parallel" means that the angle formed between the direction of the electric lines of force (vector of the electric field) and the spun yarn is less than 45 degrees, and preferably 30 degrees or less. Further, the direction in which the fit field is applied may be the same direction as the running direction of the spun yarn, or may be the opposite direction. Further, the electric field may be a direct current 17° field or an alternating electric field in which the vector direction of the electric field changes over time. These can be arbitrarily selected and used depending on the purpose.

In some cases, the DC power source 9 generates electric lines of force in the same direction as the running direction of the spun yarn Y, and as shown in (b), the DC power source 9' generates electric lines of force in the opposite direction to the running direction of the spun yarn Y. As shown in (c), the direction of the electric lines of force may be changed over time by the AC power source 9', and as shown in (d), the spun yarn Y In some cases, the traveling direction of the vehicle and the direction of the electric lines of force are inclined so that they form an arbitrary angle θ of less than 45 degrees. All of these are included in the category of ``generating lines of electric force in a direction substantially parallel to the spun yarn.''
