ける方法などがある。 Conventionally, a method for producing bound spun yarn in which fibers are wound around a substantially untwisted fiber bundle is disclosed in Japanese Patent Publication No. 43-
A method in which an aspirator torque jet is subsequently applied to the fiber bundle supplied by the final draft roller as seen in Japanese Patent Application No. 28250, or a method around the fiber bundle in the core as seen in Japanese Patent Application Laid-open No. 123954/1983. There is a method of winding a small number of fibers supplied separately.

出速度を上げられないなどの欠点があつた。 According to this method, uniform bound spun yarn with improved binding tends to be obtained, but this method has the disadvantage that it is difficult to thread the yarn at the start of spinning due to the fiber feed device, and the wind generated by this method is difficult. There were drawbacks such as the fact that cotton easily clogged, and when the spinning speed was further increased, the control of the staple fibers by the fiber feed device became unstable, making it impossible to increase the spinning speed.

明は、次の構成を有する。 Therefore, as a result of extensive research in order to solve the drawbacks of such conventional methods, the present inventor has discovered that fluid false twisting is performed while controlling the outer peripheral end fibers of the drafted fiber bundle sent out from the final draft roller by suction force. By applying this treatment, they discovered a method for rationally producing bound spun yarn with excellent binding. In order to achieve this object, the present invention has the following configuration.

が好ましい。 When the drafted fiber bundle 2' sent out from the final draft roller 6 passes over the suction surface 7 according to the present invention, the outer peripheral end fibers of the drafted fiber bundle receive absorption force from an absorption source (not shown). It is supplied to the fluid false twisting device 8 while being in contact with the suction surface, and subjected to fluid false twisting processing. Through the fluid false twisting process, the outer peripheral end fibers are wound around the substantially untwisted main fiber bundle to form a bundled spun yarn 9 which is passed through a delivery roller 10 and wound into a package 12 by a take-up roller 11. Figure 2 shows the delivery roller 10 from the final draft roller 6 in Figure 1.
It is an enlarged view of the part in between. Drafted fiber bundle 2' sent out from final draft roller 6
is in the form of a spread fiber bundle whose width has been expanded to some extent by the draft, and passes over the suction surface 7 provided immediately after, receiving suction force and coming into contact with the suction surface. The structure of the suction surface 7 is not particularly limited as long as it has a structure that allows the peripheral end fibers of the drafted fiber bundle to come into contact with the suction surface using suction force and to be lightly controlled.
For example, the structure shown in the figure having a large number of suction holes on the surface is preferable.

に巻きつき、結束効果を高めるのである。 The fiber bundle 2' receives suction force through the suction surface 7 and is drafted while in contact with the suction surface.
is supplied to the fluid false-twisting device 8 and subjected to a false-twisting action, and the suction action on the suction surface 7 significantly improves the bundling effect for the following reasons. That is, the main fiber bundle is subjected to a twisting action by the fluid false twisting device 8, and the twisting start point of the main fiber bundle reaches near the nip point of the final draft roller 6, but the suction force on the suction surface 7 The outer peripheral end fibers that are in contact with the surface and are controlled are only partially subjected to the twisting action of the main fiber bundle, and after passing the twisting point of the fluid false twisting device 8, the main fiber bundle is When untwisted, the peripheral end fibers efficiently and tightly wrap around the main bundle fiber bundle, which becomes substantially untwisted, thereby enhancing the bundling effect.

い。 Therefore, it is necessary to provide the suction surface 7 as close as possible to the final draft roller 6 and in a portion where the twisting action of the fluid false twisting device does not completely reach the drafted fiber bundle. The length of the suction surface 7 differs slightly depending on the length of the drafted fibers, but if it is too short, the control effect of the peripheral end fibers will be reduced, and if it is too long, the number of fibers flying and thread breakage will increase, so it should be determined appropriately. It is necessary to set the length to about 3 to 15 mm, and it is usually preferable to set it to about 3 to 15 mm. The width of the suction surface 7 may be at least the maximum width of the drafted fiber bundle sent out from the final draft roller 6.
The fluid false twisting device 8 applies a fluid false twisting action by a swirling flow to the drafted fiber bundle 2' that has passed through the suction surface 7, and wraps the outer peripheral end fibers of the drafted fiber bundle 2' around it. A fluid nozzle having a suction ability as disclosed in Japanese Patent Application Laid-Open No. 53-90433 is suitable. The above has described the case where the suction surface 7 and the fluid false twisting device 8 are separated.
The suction surface 7 may be an integrated structure provided near the fiber bundle introduction hole of the fluid false twisting device 8.

イードに設定される。 The effect of binding the outer peripheral end fibers by the fluid false twisting action of the swirling flow by the fluid false twisting device 8 is greatly influenced by the tension of the drafted fiber bundle, so the final draft roller 6 determines the tension.
The ratio between the surface speed of the delivery roller 10 and the surface speed of the delivery roller 10 is appropriately set to an overfeed of preferably 3 to 8%.

巻き取られる。 Next, the operation of the present invention will be described. The fiber bundle 2 is pulled out from the package 1, is supplied to the first draft roller 4 via the guide 3, and is placed between the first draft roller 4 and the second draft roller 5 and the second A draft is received between the draft roller 5 and the final draft roller 6. When the fiber bundle 2 is made of long fibers, it is subjected to a tension-cutting action in the draft zone D and is also drafted. Next, the drafted fiber bundle 2' that has passed through the final draft roller 6 passes through the suction surface 7, and is subjected to a fluid false twisting action by swirling by the fluid false twisting device 8, so that the outer peripheral end fibers of the drafted fiber bundle 2' are The bundled spun yarn 9 is wound around and tied into a bundle, which passes through a delivery roller 10 and is wound up into a package 12 by a winding roller 11.

されるのである。 As described above, according to the method of the present invention, unlike the conventional method, the drafted fiber bundle that has passed through the final draft roller receives a suction force from the suction surface and comes into contact with the suction surface, so that the outer peripheral end fibers of the fiber bundle are Since the spun yarn is supplied to the fluid false twisting device in a controlled manner and subjected to the false twisting action, the binding effect is greatly improved, and a remarkable effect is obtained in that a spun yarn with excellent yarn strength and uniformity is obtained without any loose ends. It will be done. Further, by supplying filament yarn or processed yarn from behind the final draft roller, a remarkable effect is achieved in that a composite yarn consisting of staple fibers and filament can be easily manufactured.
