生産性が低い欠点がある。 Conventionally, methods for producing knotted yarn by melt-spinning a thermoplastic synthetic polymer include a method in which the amount of molten polymer discharged from a spinneret is periodically varied, or a method in which the amount of molten polymer discharged from a spinneret is varied periodically, or a method in which the discharge amount is kept constant and the take-up speed is periodically adjusted. There are known ways to vary it. However, all of these methods have the drawbacks of complicated equipment, slow spinning speeds, and low productivity.

ある。 FIG. 4 is a model diagram showing an example of another apparatus suitable for carrying out the method of the present invention, and FIG. 5 is a perspective view of the cooling body of FIG. 4.

In FIG. 4 and FIG. 5, the ring-shaped supply pipe 1 is supplied from the pipe 13.
The cooling liquid flowing down from the outflow hole provided in the cooling body 10 forms a continuous layer of cooling liquid on the inner surface of the cooling body 10 through which the spun yarn passes, flows down to the ring-shaped tray 12, and is discharged through the pipe 14. It is becoming more and more common. FIG. 6 is also a model diagram showing another example of an apparatus suitable for carrying out the method of the present invention, in which a cooling device as shown in FIG.

本発明の方法によつて紡出糸条に節が形成され

略々規則的な多数の節が形成されるものと考えら
れる。 The reason why knots are formed in the spun yarn by the method of the present invention is not clear, but when the spun yarn is passed through a cooling liquid layer, the cooling liquid accompanying the yarn is It is thought that the coolant adheres to the thread surface intermittently in a substantially regular manner, probably due to surface tension, and that the adhered cooling liquid forms a large number of substantially regular knots.
従つて、紡出糸条が、冷却液層を通過する前に
固化していたり、冷却液層中で固化したのでは節
は形成されず、未だ固化する以前に冷却液層を通
過させ、通過した後固化させる必要がある。また
冷却液層は、紡出糸条が液層中を通過するに充分
な厚さ、即ち紡出糸条全体が浸漬されるに充分な
厚さを有する必要がある。冷却液層の厚さが充分
でなく、紡出糸条の一部が冷却液層から露出する
ときは、得られる糸条は潜在捲縮性を有するが、
節糸にならず本発明の目的を達成し得ない。ここ
で使用する冷却液としては紡出糸条に悪影響を与
えない液体であれば任意に使用できるが、工業的
には水を使用するのが好ましい。また冷却液には
界面活性剤その他の油剤を配合してもよい。 Therefore, if the spun yarn is solidified before passing through the cooling liquid layer or is solidified in the cooling liquid layer, knots will not be formed. After that, it needs to be solidified. Further, the cooling liquid layer needs to have a thickness sufficient for the spun yarn to pass through the liquid layer, that is, a thickness sufficient for the entire spun yarn to be immersed. When the thickness of the cooling liquid layer is not sufficient and a part of the spun yarn is exposed from the cooling liquid layer, the resulting yarn has latent crimpability, but
The purpose of the present invention cannot be achieved because it does not become knotted. As the cooling liquid used here, any liquid can be used as long as it does not adversely affect the spun yarn, but from an industrial perspective, it is preferable to use water. Further, a surfactant or other oil agent may be added to the cooling liquid.

糸調子が悪化する傾向があるので、30〜150mmの
範囲で適当に選択するのが望ましい。 The shape of the knotted yarn obtained by the method of the present invention, that is, the knot size, knot spacing, etc., can be adjusted by controlling the spinning conditions, cooling conditions, etc. For example, if the discharge amount is increased, the nodes will be larger and the internodes will be longer, and if the take-up speed or the temperature of the coolant is lowered, the nodes will be larger and the internodes will be shorter. Furthermore, if the distance h in FIG. 1 is made smaller, the nodes will become larger and the inter-node intervals will become shorter. If the value of h is too small, the spinning condition tends to deteriorate, so it is desirable to select an appropriate value within the range of 30 to 150 mm.

てもよい。 By stretching the knotted yarn obtained by the method of the present invention, the interval between nodes can be lengthened and the difference in diameter between the knotted part and the internodal part (necked part) can be increased. The method and conditions for drawing the yarn are arbitrarily adopted. Further, if necessary, crimps may be applied by, for example, a push-crimping device, heat treatment may be performed, and the fiber may be cut into a staple fiber, or the filament may be used as it is. .
