[Detailed Description of the Invention] [Technical Field] The present invention relates to an apparatus for producing differentially shrinkable composite yarns, and more specifically to an apparatus capable of obtaining an arbitrary shrinkage difference used in producing synthetic fiber differentially contractible composite yarns. . [Prior art] Different shrinkage composite yarns, which are made by combining two or more types of synthetic fiber yarns with different shrinkage rates, have features such as appearance, texture, and bulkiness, and have received a lot of attention in recent years as high value-added yarns. are collecting. The method for manufacturing such differentially shrinkable composite yarns is to simultaneously draw and heat-treat multiple undrawn synthetic fiber yarns, heat-treating only some of the yarns, and not heat-treating the remaining yarns. A method has been adopted in which the two threads are combined without being applied, and then the threads are wound up. In such methods, heaters are generally used to heat-treat the yarn, and contact plate heaters are often used in particular. In such a contact plate heater, if the yarn to be heat-treated is fixed, local friction and local scum adhesion at the yarn contact area on the surface of the contact plate heater can lead to fuzzing of the yarn. However, it was necessary to traverse the yarn on a contact plate heater, which was extremely inconvenient. Even if such a yarn traverse method is performed on a contact plate heater, it is necessary to periodically remove friction and scum adhesion from the surface of the contact plate heater, which requires a great deal of labor and time. Furthermore, if a method is adopted in which the yarn is traversed on a contact plate heater, when the fluid jet nozzle is used to impart single yarn entanglement to the composite yarn, the yarn position of the unit that imparts single yarn entanglement will also be Since it moves according to the traverse, it has the disadvantage that it is difficult to obtain a stable single yarn intersection. Furthermore, with a contact plate heater, it is possible to obtain an arbitrary shrinkage rate for heat-treated yarn, but the shrinkage rate of yarn that is not heat-treated remains at a fixed value if it is not in contact with the plate heater. There was a limit to the control of the difference in shrinkage of fixed, differentially shrinkable composite yarns. [Purpose and structure of the present invention] The present invention was made against the background of the above-mentioned circumstances, and its purpose is to provide a manufacturing device for differentially shrinkable composite yarn that can obtain arbitrary shrinkage differences and stable single yarn entanglement. This is what we provide. The present invention has the following configuration to achieve the above object. That is, a supply roller that supplies a plurality of undrawn synthetic fiber yarns, a stretching roller that stretches to a predetermined ratio, a heat treatment heater that heat-treats some of the yarns between both rollers, and a composite yarn that is formed by doubling after stretching. In an apparatus for manufacturing a differentially shrinkable composite yarn having a winding device for winding, a slit heater is used as a heat treatment heater, and a yarn regulating guide that can move forward and backward in the slit direction is provided at a position in front of the slit opening surface of the slit heater. It is characterized by having been established. Embodiments Hereinafter, the present invention will be explained based on the drawings. FIG. 1 is a schematic side view showing an embodiment of the present invention, and FIGS. 2 and 3 are a front view and a plan view of the guide portion of FIG. 1. In the figure, reference numerals 1 and 1' denote unstretched packages held by pegs (not shown), and guides 2 and 2' for taking out the yarn are respectively disposed at intermediate positions between these packages. Reference numerals 3 and 3' designate a pair of pretension rollers arranged below the guides 2 and 2', and a heating supply roller 5 having a yarn separation guide 4 and a separation roller 6 is provided in this order immediately below them. Furthermore, a stretching roller 7 having a separate roller 8 on the downstream side, a lappet guide 9,
The winding devices 10 are arranged in this order. Reference numeral 11 denotes a slit heater disposed between the supply roller and the stretching roller 7, and a slit 12 with a rectangular cross section extending vertically is cut in the center of the front surface. A support rod 13 is provided along the side of the slit heater 11 so as to protrude forward from the heater 11, and a guide 15 for regulating the yarn is held on the rod 13 so as to be slidable in the horizontal direction. and is fixed in a predetermined position via a bolt 14. The thread regulating guide 15 has a thread guiding groove 16 formed at its tip, and this groove 16 (not necessarily required) is located in front of the slit 12 of the heater 11 and at a position facing the slit 12. It is fixed to be. The support rod of the guide 15 has a rectangular (or polygonal) shape in addition to the circular cross section.
It can have any shape such as. Guide 15
The shape of the thread contacting part is not limited to a rod shape, but may be arbitrarily selected such as a drum shape, a hook shape, etc., but it is preferable that the thread contacting part has a groove shape, a constriction shape, or a drum shape in order to fix the thread position. Reference numeral 17 denotes a thread alignment guide arranged below the slit 12 between the slit heater 11 and the stretching roller 7. Synthetic fibers in the present invention refer to thermoplastic synthetic fibers that can be drawn and heat treated, such as polyester fibers and polyamide fibers. In particular, the present invention is suitable for application to polyester fibers, in which at least one of the plurality of undrawn yarns is made of polyethylene terephthalate or a copolyester containing polyethylene terephthalate as a main component. It is preferable that Of course, there is no problem even if the plurality of undrawn yarns are a combination of fibers made of different types of polymers, such as polyester fibers and polyamide fibers. [Operations and effects of the present invention] In the device having such a structure, the undrawn yarns Y, Y' pulled out from the undrawn packages 1, 1' via the guides 2, 2' are connected to a pair of pretensioners. It is sent to a separation guide 4 via rollers 3 and 3', where it is completely separated and transferred to a heating supply roller 5.
After being wound several times around the separate roller 6, the yarn Y is wound through the slit 1 of the slit heater 11.
2 and undergoes heat treatment. On the other hand, yarn
Y' is connected to the slit heater 11 by the guide 15.
The yarn Y is passed through the front surface of the heater 11 without being heat-treated while being substantially separated from the slit heater 11, and is engraved on the yarn alignment guide 17 located directly below the slit heater 11 together with the yarn Y that has passed through the slit heater 11. Both yarns Y, Y' are brought together by running in contact with the grooves 18, then both yarns Y, Y' are wound several times between a drawing roller 7 and a separate roller 8, and after drawing and combining, the yarns are passed through a rappet guide 9. The yarn is twisted and wound on a winding device 10 of a ring twisting machine. Here, when controlling the shrinkage rate of yarn Y' without heat treatment, guide 1 along support rod 13
By moving 5, the desired shrinkage rate can be adjusted very easily. In other words, as a result of this movement, a part of the other yarn Y' approaches or moves away from the top or bottom of the slit 12 of the slit heater 11, so that the yarn Y'' can be increased or decreased as appropriate. In the above, an example has been described in which the yarn is directly twisted and wound after being drawn and combined, but the present invention is an apparatus that uses a fluid injection nozzle after drawing to impart single fiber entanglement to the composite yarn, or a device that provides single yarn entanglement without twisting after drawing. Needless to say, the present invention can also be applied to a winding device using a twist winder. Further, the thread regulating guide 15 may be automatically moved to an arbitrary position or a predetermined position in multiple stages using a mechanism such as a fluid cylinder or a motor. Further, the number of guides 15 is not limited to one, but two or more guides may be arbitrarily adjusted so as to reliably and accurately regulate the degree of heat influence. Next, to explain the effects of this invention in more detail,
A pair of polyethylene terephthalate undrawn filament (30 denier/12 filament) packages were taken up at a spinning speed of 1300 m/min using the apparatus shown in Fig. 1 at a stretching ratio of 2.83 and a circumferential speed of the drawing roller 7 of 800 m/min. The stretching heat treatment was carried out under the following conditions: the surface temperature of the heating supply roller 5 was 83°C, and the heater temperature of the slit heater 11 was 200°C. At this time, one of the two polyethylene terephthalate yarns Y and Y' is separated from the slit heater 11 by the guide 15 and is not heat-treated, while the other yarn Y passes through the slit 12. heat treated,
Next, these yarns Y and Y' were combined and wound using a ring twisting machine to obtain a differential shrinkage composite yarn. The distance a (Fig. 4) of the thread Y' from the front surface of the slit opening at the top of the slit heater 11 is 0.
By moving the guide 15 within the range of ~22 mm, the boiling water shrinkage percentage of the yarn Y' without heat treatment was obtained in the range of 17.8 to 11.0% as shown in Table 1. As can be seen from this table, the yarn Y' with the required boiling water shrinkage rate is determined by simply connecting the guide 15 to the slit heater 11.
It can be obtained very easily by simply moving the yarn back and forth, and it is possible to stably and reliably produce various types of differentially shrinkable composite yarns as required. 【table】
