The present invention relates to a method for manufacturing mixed fiber yarn. More specifically, the present invention relates to a method for producing a mixed fiber yarn that can evenly mix crimped yarn and substantially non-crimped yarn. Conventionally, methods have been proposed in which crimped yarns and non-crimped yarns such as high-shrinkage yarns are blended using fluid or static electricity. A method for properly dispersing and mixing each filament group has not yet been found. especially,
Blending technology using fluids has the advantage of being able to process at high speed with an extremely simple process, but all of the yarns proposed so far are composite yarns with a core-sheath structure, with loops and snarls on the yarn surface. Many have. Therefore, these composite yarns may have poor unraveling properties, or may develop nap-like defects due to straining during the weaving process, for example, when passing through various yarn guides or reeds during weaving. There is a problem that productivity and quality are significantly reduced due to thread breakage and thread breakage. In view of the above-mentioned conventional drawbacks, the present invention provides a method for producing a blended yarn that can be processed with extremely high efficiency and high quality during the weaving and weaving process, and that exhibits a soft, spun yarn-like feel. . The present invention has been achieved as a result of various studies aimed at achieving the above object by appropriately designing the crimp characteristics of crimped yarn and using an appropriate fiber blending method, and has the following configuration. That is, the structure of the present invention is that a multi-filament temporary twist yarn that has been temporarily twisted with a heating-heat-setting-untwisting temporary twist element is then stretched under overfeed conditions. The reheat-set provisional twist yarn obtained by heat treatment is merged with the multifilament yarn that is substantially free of crimps, and a high-speed fluid stream is jetted from a direction substantially perpendicular to the merged yarn. let me,
This method of manufacturing a mixed fiber yarn is characterized in that vibration is excited in the yarn so that the yarn crosses the high-speed fluid flow intermittently to impart entanglement and blend processing. The present invention will be explained in detail below. In the blending process of the present invention as described above, in particular, reheat-set temporary twist yarn and substantially non-crimped multifilament yarn (hereinafter, this yarn is simply referred to as non-crimped yarn or non-crimped yarn) A high-speed fluid stream is injected from a substantially perpendicular direction to the yarn that has merged the yarns (hereinafter referred to as yarns of This provides intertwining, and this will be explained below based on the drawings. FIG. 1 shows one implementation step of the method for producing a mixed fiber yarn of the present invention. In FIG. 1, a yarn 1 is temporarily twisted by a series of temporary twisting elements consisting of a first roller 2, a first heater 3, a spindle 4, and a second roller 5.
The crimps of the multifilament tentative yarn are stretched between rollers 7 under overfeed conditions, and the second
By passing through the heater 6, the thread is reheated and becomes a reheated set provisional twist thread. It should be noted that the temperature of the second heater 6 is 160 to 230°C, which is sufficient to reheat and set the tentative twist yarn, so-called woolly yarn, supplied from the second roller 5, and that the temperature between the second roller 5 and the third roller 7 is 160 to 230°C. Now, the second roller 5
The circumferential speed of the third roller 7 is 10 to 20
(%) It is preferable to perform reheat setting under conditions of a large overfeed rate (here, the woolly yarn fed by the second roller 5 is a high stretch yarn with extremely large crimp elongation, and In this case, the crimp is stretched due to the unraveling tension of the temporary twist.Therefore, by setting the feed rate between the second roller 5 and the third roller 7 to the above-mentioned overfeed, the crimp is expanded. (can be made into a semi-stretched state). On the other hand, non-crimpable multifilament yarn is
The yarn is fed from the fourth roller 8 and is merged with the reheated set tentative yarn fed from the third roller 7 by the merging guide 9, guided to the high-speed fluid jetting device 10, and subjected to a mixed fiber treatment. Winding device 1 via roller 11
It will be picked up at 2. Note that the manufacturing process of the present invention is not limited to the method of processing the reheat-set temporary twist yarn as described above and then continuously mixing it with a non-crimpable multifilament yarn. It is also possible to make a tentative twist yarn once reheated and then intermittent it to mix it with a non-crimped yarn. However, the method shown in Fig. 1, in which reheated set tentative twisted yarn is made in one process and is combined with non-crimped yarn for mixed fiber treatment, is advantageous in terms of quality and cost, and is suitable for production. Most preferred. Further, it is also possible to use a highly oriented undrawn yarn or an undrawn yarn as the yarn 1 which becomes the reheat-set tentative twist yarn, and temporarily twist it at the same time as drawing with the above-mentioned temporary twist element. Particularly in this case, since the highly oriented undrawn yarn or undrawn yarn is essentially a non-twisted yarn, it is easy to open the yarn when it becomes a reheat-set temporary twisted yarn.
It has the advantage of being able to be mixed well with non-crimped yarn and being able to be processed at high speed. The reheat-set provisional twist yarn is obtained by reheat setting the woolly yarn, which has been temporarily twisted using a normal temporary twisting element as described above, in a semi-stretched state by heat treatment. Therefore, while ordinary woolly yarn is a high stretch yarn with a large torque and a high crimp elongation rate (at least 40%) consisting of a three-dimensional crimp with complicated snarls and intersecting loops, the yarn of the present invention Heat set temporary twist thread
(a) Torque is small. (b) The crimp form is a nearly two-dimensional wave shape, and the crimp elongation is low. (c) It has properties suitable for the present invention, such as a low shrinkage rate in boiling water, as described below. As a comparative example, when a woolly yarn and a non-crimped yarn, which are not reheated and set as described above, are mixed using a high-speed fluid jetting device, it is difficult to open the woolly yarn, and the torque is large, so a single yarn of the woolly yarn is mixed. The result is that they do not properly intermingle with the non-crimped threads, but either become entwined around the non-crimped threads in a sheath-like manner, or become entangled with the non-crimped threads separated. Therefore, the yarn shape of the yarn obtained by this method is easily changed by external forces during the weaving and weaving process, causing various troubles, and when the yarn is heat-treated, it becomes increasingly woolly due to residual torque and shrinkage. The intertwining of single threads becomes stronger, making it impossible to obtain a soft feel. As mentioned above, the crimped yarn to be mixed with the non-crimped yarn must have appropriate crimp characteristics, and reheat-set temporary twisted yarn as in the production method of the present invention is most preferred. In other words, since the reheat-set temporary twist yarn has the above-mentioned characteristics (a), (b), and (c), it is possible to mix the two filament groups with the non-crimped yarn in a moderately dispersed manner. It is. Therefore, the mixed fiber yarn obtained by the present invention exhibits extremely good passability during the weaving and knitting process, and knitted fabrics using such a mixed fiber yarn exhibit a soft touch similar to that of spun yarn. In the method for producing a blended yarn of the present invention, the fiber to be processed as the reheat-set temporary twist yarn is a multifilament of thermoplastic synthetic fiber such as polyester, polyamide, polyacrylonitrile, etc.
Any type of fiber can be used, but polyester fibers are particularly preferred since they can be easily reheated. When using polyester fiber,
The reheat-set temporary twist yarn obtained by the method described above generally has low elongation with a crimp elongation rate of 25% or less,
It has a low torque with a torque twist count of 40 times/50 cm or less, and has low shrinkage characteristics with a boiling water shrinkage rate of 3% or less. On the other hand, the non-crimped yarn can be any type of fiber, such as thermoplastic synthetic fibers or cellulose acetate fibers, as long as it is a non-crimped multifilament yarn, and can be selected and used depending on the purpose and use. be. For example, when using fibers with high shrinkage properties, extremely high bulk properties can be obtained. In addition, the range of applications is wide-ranging, such as when using reheat-set temporary twist yarn and fibers of different colors or different dyeing properties, a heathered and marbling color effect with good convergence can be obtained. Next, the fiber mixing treatment method will be explained. The reheat-set provisionally twisted yarn and the non-crimped yarn are fed by separately equipped third rollers 7 and fourth rollers 8, merged by a merging guide 9, and mixed in a high-speed fluid jetting device 10. However, at this time, if a high-speed fluid stream is injected from a direction close to parallel to the merged yarns, loops and sagging are likely to occur, and the resulting mixed yarn will cause various troubles during the weaving and weaving process, making it undesirable. do not have.
Therefore, in the present invention, for the merged yarns,
In the most preferred embodiment, a high-speed fluid flow is injected from a substantially perpendicular direction to excite vibrations in the threads so that the threads intermittent cross the high-speed fluid to impart entanglement. be. When supplying the reheat-set tentative twisted yarn and non-crimped yarn to the high-speed fluid jetting device 10, the third roller 7 and the fourth roller 8 are connected to the fifth roller 11.
It is preferable that the feed rate is a low overfeed rate of 0 to 5%, and the feed is performed under the condition that the circumferential speed of the third roller 7≧the circumferential speed of the fourth roller 8. The mixed fiber yarn obtained by the above method does not have loops or snarls and has intermittent entanglement in the longitudinal direction of the yarn, so it has excellent unraveling properties and ability to pass through various yarn guides. It becomes possible to weave and weave with high efficiency and high quality. In addition, in the above description, the crimp elongation rate and the torque twist number are values obtained by the following measurement methods. (Crimp elongation rate) Make a small skein sample from the sample package under a tension of 0.1 g/d or less, immerse it in hot water for 20 minutes with a load of 2 mg/d, then remove the load and drain the water. ,
Leave for 12 hours or more to achieve moisture equilibrium. Next, hang one end of the skein on a hook, and apply the processing load (2
mg/d) and read the length (l 1 ) after 30 seconds. Next, a load of 100 mg/d was applied, the length (l) was read 30 seconds later, and was determined from the following formula. Crimp elongation rate (%) = l - l 1 / l 1 × 100 (number of torque twists) Approximately 1.5 m of yarn was taken out from the product form (corn or cheese) in the vertical direction to avoid twists due to torque. Apply a load of 50 mg/d to the center of the thread, and fold the thread in half to prevent it from twisting due to torque. Next, hold the folded thread so that it does not rotate, and add the specified length (50 cm) to the above-mentioned combined thread.
mark. After that, the lower part of the combined yarn is left free, a twist is applied by torque, and the twist is left until the twist becomes stable. After that, the number of twists of the combined yarn is measured using a detector. Therefore, the torque twist number is expressed in units of times/50cm, and the lower the number, the lower the torque. Examples will be described in detail below. Example 1 In the process shown in Figure 1, thread 1 was made of 75D-36F.
Using a polyester multifilament yarn, while processing the reheat set tentative twist yarn A that will become the yarn, using a non-crimped yarn B of 40D-10F polyamide multifilament as the yarn, the former yarn A and the latter yarn B are merged into the guide 9. After merging with
A high-speed air flow with an air pressure of 2.7 Kg/cm 2 (gauge pressure) was injected from the vertical direction to the combined yarns to perform a fiber mixing treatment.

In addition, as a result of knitting a tricot knitted fabric with the following contents using the above-mentioned mixed fiber yarn, it showed extremely excellent workability in the warping and knitting steps. a Warping speed: 300m/min Number of warping threads: 196 pieces/beam (7″ width) Warping length: 7500m (500m x 15 beams) b Knitting machine: 28G single tricot knitting machine rotation speed: 700c.pm Knitting structure: Half Front yarn: The above blended yarn Back yarn: 20D-1F polyester yarn In addition, the resulting tricot fabric was dyed in the usual way, resulting in a soft spun yarn-like surface feel. Example 2 In the process shown in FIG. 1, the merging guide 9, high-speed fluid jetting device 10, fourth roller 8, and fifth roller 11 were substantially used First, use 75D-72F polyester multifilament yarn as the yarn, reheat the yarn in advance, and temporarily twist yarn C.
was processed and rolled into cheese form. The physical properties of the obtained reheated set temporary twist yarn C were as follows. Crimp elongation rate 18% Number of torque twists 32 pieces/50cm Boiling water shrinkage rate 1.1% The main processing conditions for reheat set provisional twist yarn C are processing conditions (1), (2), and (3) shown in Example 1. ), (4), (5)
It was conducted under the same conditions as. Next, in the process shown in FIG. Using only the fiber processing process, 50D-24F polyester multifilament non-crimped yarn D is merged with the above-mentioned reheat-set temporary twist yarn C, and the merged yarn is subjected to an air pressure of 2.5 perpendicularly. A high-speed air flow of Kg/cm 2 (gauge pressure) was injected to perform fiber mixing treatment. At this time, the fifth
By keeping the circumferential speed of the roller 11 constant (100 m/min) and changing the circumferential speeds of the third roller 7 and the fourth roller 8, the mixed fiber processing feed rate of the reheat-set temporary twisted yarn C and the non-crimped yarn D can be obtained. The mixed fiber treatment was carried out with various changes, and the results are shown in Table 1.
