Description

Manufacturing method of fake fuck processing thread The present invention relates to a method of manufacturing threads for dummy machining threads. The manufacturing method of prosthetic machining yarns obtained by machining the yarns (raw strands) composed of filaments of synthetic fibers is revealed in patent literature 1 More specifically, by heating and stretching the incoming raw strands while adding stitches to the raw strands, formed after the retraction Residually turned pseudonyms processing threads as protofilaments are usually produced using partially oriented threads (i.e., the polymers are partially oriented) with the orientation of the polymers constituting the filaments. Patent Literature 1: Japan Special Bulletin No. 2016-141912 Patent Literature 2: Japan Special Opening No. 2008-138301 [Problem to be solved by the invention] When the raw threads composed of POY are processed, usually if the travel speed of the thread (processing speed) is higher than a certain limit speed, it will produce vibration (oscillation) of the thread and become unable to perform normal false processing is well known. The object of the present invention lies in the ability to improve the limit speed of processing threads for the production of dummies [as a means of solving the problem]. A method of manufacturing a dummy machining yarn of the first invention is made using a dummy processing machine configured to be able to perform dummy processing of the preceding raw strands by heating and stretching the traveling raw yarn while performing a dummy on it , the fabrication method of the aforementioned dummy jib processing yarn is characterized as follows: the preceding dummy pinch processing machine has: a heating apparatus which heats the preceding raw strand; Configured on the downstream side of the aforementioned heating device, the aforementioned raw thread is dummy, the residual elongation before machining is less than 100%, the boiling water shrinkage before machining is less than 3.7% or less than 25%, and the strength before dummy processing For partially oriented yarns composed of synthetic fibers made of PET above 2.9cN / dtex were used as the aforementioned raw strands, while heating and stretching the aforementioned raw strands, they were processed at a processing speed above 1100m / min. In the dummy machine, the raw threads are cranked by the dummy device. Oscillations are mainly produced by repeated relaxation or tightening of the threads from slipping in the dummy device. In general, the higher the travel speed (machining speed) of the yarn in the dummy jib device, the easier it is for the yarn to slip in the dummy jib device, and if the machining speed exceeds the limit speed, oscillation is produced. In this case, the inventors found that the limit speed is increased when the residual elongation before processing (hereafter, referred to as pre-processing elongation) is less than 100% and the boiling water shrinkage before processing of the dummy is as low as 3.7% or less than 25%, the limit speed is increased. Namely, it was found that the generation of oscillations could be suppressed even if the machining speed of pseudonym processing of such raw threads was increased above 1100m / min. With respect to that ground, the inventors herein examine as follows. The low elongation and boiling water shrinkage before processing generally means that the orientation of the polymers constituting the protofilament progresses and the crystallization of the protofilament also progresses. When sham machining is performed on such a strand, the tension applied to the strand (hereinafter, referred to as the machining tension) on the immediately upstream side of the yarn travel direction of the strand device becomes higher. More specifically, the machining tension is determined mainly by the relaxation of orientation of the protofilament resulting from heating by the heating device and the resistance of the protofilament against stretching. That is, if the orientation of the protofilament eases, the protofilament traveling generally on the upstream side of the thread travel direction of the pseudo-pin device heat shrinks. If the thermal contraction force is large, the machining tension also becomes large. Furthermore, the portion of the crystallization progression in the protofilament did not produce an orientational relaxation, but the aforementioned resistance became larger because of the higher stiffness of that portion. If that resistance is large, the machining tension also becomes larger. This is so, mainly for two reasons, when the elongation before machining of the raw yarn is less than 100% and the boiling water shrinkage is less than 25%, the machining tension becomes larger. Therefore, it is able to inhibit the relaxation of the thread when the thread is dummed. Therefore, it is able to suppress the generation of oscillations. On the other hand, if the boiling water shrinkage rate is too low (i.e., if the crystallization of the protofilament progresses excessively), the torsional stress generated when the protofilament is sham is enlarged. If the torsional stress is too large, the elastic restoring force for the twisted thread becomes excessive, so the thread is prone to slipping in the torsional direction in the dummy cock device. In this case, the inventors examined that in order to suppress the slipping of such threads, the boiling water shrinkage rate needs to be greater to some extent (specifically, more than 3.7%). Furthermore, since the strength of the protofilaments is high above 2.9cN / dtex, even large tension applied to the protofilaments can inhibit the protofilament breaking. that is, able to inhibit the production of fluffing and / or thread breakage during dummy processing. According to the above, it is able to improve the limit speed that can produce dummy pinch processing threads. The method of manufacturing the dummy-handled processed thread of the second invention is as in the first invention, wherein, the preceding elongation of the preceding raw thread is 80% or more. The excessively low elongation of the protofilament before processing generally means that the aforementioned torsional stress is easily increased if the crystallization is excessive. The method of manufacturing the dummy-processed yarn of the third invention is as in the first or second invention, wherein the boiling water shrinkage of the preceding dummy strand before processing is 3.7% or more or less than 10%. In the present invention, it is possible to increase the aforementioned resistance. The method of manufacturing the machining thread of the 4th invention is characterized by that in any of the inventions of the 1st to 3rd invention, wherein the orientation of the preceding raw yarn before the machining of the dummy is 1.23 or above and below 1.38. In general, there is a tendency for crystallization to also overprogress if the orientation of the protofilament is overprogressed According to the present invention, the orientation is not too high or too low, thus enabling the machining tension to be increased and the torsional stresses of the foregoing to become excessive. The method of manufacturing the yarn for processing yarns of the 5th invention is as in any of the preceding inventions 1~4, wherein the crystallinity of the preceding raw yarn before the machining of the nymphomaniac is 26% or more or less than 38%. In the present invention, the crystallinity is not too high or too low, thus enabling an increase in the machining tension and able to suppress the aforementioned torsional stresses from becoming excessive. The method of manufacturing the dummy machining yarn of the 6th invention is as in any of the foregoing 1~5 inventions, wherein the target value of the residual elongation of the formed preceding dummy machining yarn is set to be 18% or more or less than 26%. In the present invention, it is possible to manufacture dummy machining threads with general residual elongation. Then, the embodiment form of the present invention is illustrated for ease of exposition, the vertical direction of the paper surface of FIG The direction of the two sides orthogonal to the direction of the stage width is set as the up and down direction of the action of gravity (the direction of the stage width). (Overall structure of the dummy machining machine) First, the overall structure of the dummy machining machine 1 used to implement the fabrication method of the dummy machining thread Yf of this embodiment is illustrated with reference to FIG. The dummy clamp processing machine 1 is configured to produce dummy clamp processing yarn Yf by performing pseudo-pin processing on the yarn Y (raw yarn Yr). The raw yarn Yr is, for example, a yarn composed of polyester-based synthetic fibers. The original thread Yr is, for example, a complex thread composed of multiple filaments. Alternatively, the raw thread Yr may also be composed of 1 filament. The protofilament Yr is the general partially oriented thread (POY) constituting the polymeric partial orientation of each filament. The raw yarn Yr is formed by the aforementioned spinning and winding equipment 100 (referring to FIG. 3 ). The dummy machining machine 1 is equipped with thread supply 2, machining 3 and winding 4. The thread supply portion 2 is configured to be capable of supplying thread Y . The machining section 3 is configured to pull out the thread Y from the thread supply section 2 and perform dummy pinch machining. The winding portion 4 is configured to wind the thread Y processed by the machining portion 3 in the winding cylinder tube Bw. The various constituent elements possessed by the thread supply portion 2, the processing portion 3 and the winding portion 4 are arranged in a plurality in the direction of the length of the machine (refer to Figure 2). The direction of the machine length is the direction orthogonal to the travel surface of the thread Y (the paper surface of FIG. The thread supply section 2 has a cylinder frame 7 that holds a plurality of thread feeder curling Ps, and supplies a complex number of threads Y (original thread Yr) to the processing section 3 . The machining portion 3 is configured for machining by pulling a plurality of strands Y from the thread supply portion 2 . The machining section 3 is configured to be configured sequentially from the upstream side of the thread travel direction, for example, a first feed roller 11, a stopper thread guide 12, a first heating device 13, a cooling device 14, a dummy device 15, a second feeder roller 16, an interweaving device 17, a third feeder roller 18, a second heating device 19 and a 20th feeder roller. The winding portion 4 has a plurality of winding devices 21 . Each winding device 21 winds the thread Y processed by the machining section 3 on the winding barrel tube Bw to form a winding winding Pw. Hereafter, the yarn Y processed by the processing department 3 dummy is also referred to as the dummy machining yarn Yf. The dummy machine 1 has a host stage 8 and a winding stage 9 configured at intervals in the direction of the stage width. The main stage 8 and the winding stage 9 are provided to extend at approximately the same length in the direction of the stage length. The host stage 8 and the winding stage 9 are configured to oppose each other in the direction of the stage width. The dummy machine 1 has a unit unit known as a span. A span contains a set of host stations 8 and winding stations 9 . In a span, the devices are configured to perform simultaneous sham machining on a plurality of strands Y traveling in a state arranged in the direction of the length of the machine. In the dummy machine 1, the span is configured symmetrically left and right on the paper with the center line C in the direction of the machine width direction of the main stage 8 as the axis of symmetry (the main stage 8 is shared in the left and right spans). In addition, the plural spans are arranged along the length of the machine stage. (Structure of the machining department) The structure of the machining section 3 is illustrated with reference to Figs The thermal apparatus 13 transports 1 thread Y. Alternatively, the first feeder roller 11 may also be configured to transport adjacent plurality of threads Y to the downstream side of the thread travel direction respectively, the transport speed of the first feeder roller 11 to the thread Y is referred to as the first feeder velocity. The stopper thread guide 12 is configured so that the jig applied to the thread Y by the dummy jig device 15 does not propagate to the upstream side of the thread travel direction than the stopper thread guide 12 , the first heating device 13 is used to heat the thread Y transported from the first feed roller 11 to a prescribed processing temperature (e.g., the heating device 13 of the present invention). Configured to be capable of heating two threads Y. The number of threads Y capable of heating of the 1st heating device 14 is not limited to this. The dummy device 15 is configured on the downstream side of the thread travel direction of the 1st heating device 13 and the cooling device 14. The dummy device 15 is configured to add a cock to the wire Y for example Apparatus.Pseudo-pin device 15 has a plural of disks configured in a spiral shape (not illustrated) The plural of disks are driven by rotation in the same direction Thus, by action to thread Y and the surface of each disk, the thread Y is added. The second feeder roller 16 is configured to transport the thread Y treated by the dummy jig apparatus 15 to the interweaving device 17. The transport speed of the second feeder roller 16 to the thread Y is referred to as the second feeder thread speed The speed of machining (hereafter, referred to as the machining speed) is prescribed for example by the 2nd feed yarn speed than the 1st feed yarn speed Therefore, the thread Y is stretched between the 1st feeder roller 11 and the 2nd feeder roller 16 . The ability to combine the first feeder roller 11 and the second feeder roller 16 is referred to as a stretching device Tension is applied to the thread Y traveling between the feed rollers 16 In the following, for ease of exposition, the tension applied to the thread Y traveling on the immediately upstream side of the thread travel direction of the dummy cock device 15 is also referred to as the machining tension. The interweaving device 17 is configured to apply interleaving to the thread Y . The interlacing device 17 is, for example, a staggered nozzle that applies intertwined habits to the thread Y by means of an airflow. The 3rd feeder roller 18 is configured to transport yarn Y traveling on a downstream side than the interwoven device 17 in the direction of yarn travel to the 2nd heating apparatus 19 . As shown in FIG. Alternatively, the third feeder roller 18 may also be configured to transport adjacent plural strands Y to the downstream side in the direction of the strand travel, respectively. In addition, the transport speed of the 3rd feed roller 18 to yarn Y is slower than that of the 2nd feeder roller 16 to the yarn Y. Thus, thread Y relaxes between the second feeder roller 16 and the third feeder roller 18 . The second heating device 19 is configured to heat the thread Y transported from the third feeder roller 18 . The 2nd heating device 19 extends in the direction of the lead pendant and is provided one each in a span. The fourth feeder roller 20 is configured to transport the heated thread Y from the second heating device 19 to the winding device 21 . For example, as shown in FIG. Alternatively, the fourth feeder roller 20 may also be configured to transport adjacent plural strands Y to the downstream side in the direction of the yarn travel, respectively. The transport speed of 20 pairs of yarn Y in the 4th feed roller is slower than that of 18 pairs of yarn Y in the 3rd feeder roller. Thus, thread Y relaxes between the third feeder roller 18 and the fourth feeder roller 20 . In the machining section 3 as constituted above, the thread Y being stretched between the first feeder roller 11 and the second feeder roller 16 is added by the dummy device 15 . The jig turn formed by the dummy device 15 propagates to the stopper thread guide 12 , but does not propagate upstream than the stopper thread guide 12 in the direction that the thread travels. The thread Y that is stretched while being pinned is cooled by the cooling device 14 after being heated and thermally set by the 1st heating device 13 . On the side downstream than the direction of thread travel of the dummy device 15, the thread Y is receded, but by resorting to the aforementioned thermal shaping to maintain the state of the thread Y being dummy as wave-like (i.e., maintaining the curl of the thread Y). The thread Y where the dummy is implemented is interlaced by the interweaving device 17 while being relaxed between the second feeder roller 16 and the third feeder roller 18, after which it is guided downstream in the direction of the thread travel direction. Further, the side of the thread Y is heat treated by the second heating device 19 while relaxing between the third feeder roller 18 and the fourth feeder roller 20 . Finally, the yarn Y transported from the 4th feeder roller 20 is wound by means of the winding device 21 (false-handed machining yarn Yf). (Structure of the winding section) The structure of the winding section 4 will be described with reference to Fig. 2. The winding section 4 has a plurality of winding devices 21. Each winding device 21 is configured, for example, to wind the thread Y around a single winding bobbin Bw. The winding device 21 has a fulcrum thread guide 31, a traversing device 32, and a cradle 33. The fulcrum thread guide 31 is a thread guide that serves as a fulcrum when the thread Y traverses. The traversing device 32 is configured to traverse the thread Y by means of a traversing thread guide 34. The cradle 33 is configured to support the winding bobbin Bw so as to be rotatable. A contact roller 35 is disposed near the cradle 33. The contact roller 35 contacts the surface of the winding package Pw and applies a contact pressure. In the winding section 4 configured as described above, the thread Y conveyed from the fourth thread feed roller 20 is wound around the winding bobbin Bw by each winding device 21 to form a winding package Pw. (Spinning and winding equipment) The spinning and winding equipment 100, which is an example of the equipment for manufacturing the raw yarn Yr, will be described with reference to Fig. 3. Fig. 3 is a schematic side view of the spinning and winding equipment 100. For ease of explanation, a specified direction orthogonal to the vertical direction is referred to as the front-back direction. The front-back direction is a direction parallel to the left-right direction of the paper surface of Fig. 3. A direction orthogonal to both the vertical direction and the front-back direction is referred to as the left-right direction. The left-right direction is a direction parallel to the direction perpendicular to the paper surface of Fig. 3. The spinning and winding equipment 100 is configured to wind the spun thread Y around a bobbin B to form a package P (the aforementioned supply package Ps). The spinning and winding equipment 100 includes a spinning device 101, a cooling device 102, a drawing section 103, and a winding section 104. The spinning device 101 is configured to eject (spin) a molten polymer that is the material for a plurality of threads Y (raw yarn Yr). The cooling device 102 is configured to cool the molten polymer and solidify it. Since the molten polymer is solidified, a plurality of threads Y each having one or more filaments are formed. An oil application device (not shown) for applying an oil agent to each thread Y is provided below the cooling device 102. The drawing section 103 is configured to draw down a plurality of threads Y. The drawing section 103 has, for example, a first thread guide roller 111 and a second thread guide roller 112. The first thread guide roller 111 is disposed below the spinning device 101, the cooling device 102, and the oil application device. The first thread guide roller 111 is configured to draw a plurality of threads Y and convey them to the second thread guide roller 112. The second thread guide roller 112 is disposed, for example, above and to the rear of the first thread guide roller 111. The second thread guide roller 112 is configured to convey a plurality of threads Y toward the winding section 104. The winding section 104 is configured to wind a plurality of threads Y around a bobbin B to form a package P. The winding section 104 is disposed below the second thread guide roller 112. The winding section 104 includes a plurality of fulcrum thread guides 121, a plurality of traversing thread guides 122, a turntable 123, two bobbin holders 124, and a contact roller 125. A plurality of fulcrum thread guides 121 is a thread guide that becomes a fulcrum when thread Y is moved horizontally by each transverse thread guide 122 . A plurality of fulcrum thread guides 121 are arranged in an anteroposterior direction. A plurality of fulcrum thread guides 121 is set separately with a plurality of strands Y correspondingly. A plurality of horizontally moving thread guides 122 is a thread guide used to cause the complex number of strands Y to move separately laterally. A plurality of transverse thread guides 122 are arranged in an anteroposterior direction. A plurality of lateral-moving thread guides 122 and a plurality of fulcrum thread guides 121 are correspondingly provided separately. Turntable 123 is a roughly round plate-shaped component. The axial direction of turntable 123 is roughly parallel to the anterior and posterior direction. The turntable 123 is driven by rotation of the turntable motor not illustrated. The two cylinder brackets 124 are configured to support a plurality of cylinder tubes B arranged in an anteroposterior direction. The axial direction of each cylinder tube bracket 124 is substantially parallel to the anterior-posterior direction. The two cylinder tube brackets 124 are capable of rotatingly supported on the turntable 123 . When viewed from an anterior and posterior direction, the two cylinder brackets 124 are configured on opposite sides of each other separated by a central point of the turntable 123 . More specifically, for example, when the cylinder bracket 124 of one party is located on the uppermost side, the cylinder bracket 124 of the other party is located on the lowermost side. Each cylinder bracket 124 supports a plurality of cylinder B separately disposed relative to the plurality of thread Y to be capable of rotation. At each cylinder bracket 124 , a plurality of cylinder tubing B disposed correspondingly to the plurality of strands Y, respectively, is arranged in an anterior and posterior direction. The two cylinder tube brackets 124 are respectively driven by a separate winding motor (not illustrated) by rotation. The contact roller 125 is a roller that is roughly parallel in the axial and anteroposterior directions. The contact roller 125 is configured immediately above the barrel bracket 124 on the upper side. The contact roller 125 adjusts the shape of the roller P by applying contact pressure to the surface of the roller P in the winding by making contact with the surface of a plurality of coiled Ps supported on the upper side of the cylinder tube bracket 124 . When the cylinder bracket 124 on the upper side is driven by rotation, a winding P is formed by the traverse Y from the transverse thread guide 122 being wound around the cylinder tube B. Furthermore, in the case where the roll P becomes a full roll, the upper and lower positions of the two barrel brackets 124 are adjusted by rotating the turntable 123 . Thus, the cylinder bracket 124 located on the lower side moves to the upper side, capable of forming a coiled P at the cylinder B mounted on the cylinder bracket 124 by winding the wire Y. In addition, the barrel bracket 124 mounted with becoming a full roll of reel P is moved from the turntable 123 to the lower side. Full rolls of roll P are recycled by means of an uncharted roll recovery device, for example. The recovered curling P is installed as the aforementioned feed curling Ps in the wire feed section 2 of the dummy jig processing machine 1 . Here, in general, it is known that if the travel speed (machining speed) of yarn Y in the dummy pin processing machine 1 is higher than a certain limit speed (also called the oscillation speed), the vibration (oscillation) of the yarn Y is generated, and the pseudo-pin processing yarn Yf cannot be produced normally. On the other hand, in recent years, it has been required to further improve the production efficiency of the fake cock processing thread Yf. The inventors of this case conducted an in-depth study, and as a result, they discovered the method used to improve the limit speed of dummy machining (capable of producing the limit speed of the dummy pin processing yarn Yf). In the following, the limit speed of dummy machining is also referred to as the limit speed. (Machining conditions required for dummy machining) Before describing the manufacturing method of dummy machining thread Yf of this embodiment, the following, briefly describe the processing conditions required when dummy machining of the raw thread Yr (more strictly for tensile dummy machining) to manufacture the dummy machining thread Yf. The raw strand Yr before machining by the dummy pin processing machine 1 The raw strand Yr before the dummy pin has a prescribed residual elongation (elongation before machining) as a characteristic inherent in that raw strand Yr. The residual elongation of thread Y refers to the elongation of thread Y after stretching thread Y and causing it to break under specified conditions. That is, the residual elongation is the elongation of the thread Y after breaking relative to the thread Y before stretching. The residual elongation of raw yarn Yr can be varied according to the manufacturing conditions of raw yarn Yr in the spinning winding equipment 100 . Furthermore, the strength of raw yarn Yr (tensile force at breakage of raw yarn Yr) can also vary according to the manufacturing conditions of raw yarn Yr in the spinning winding equipment 100 . It is generally required to perform dummy machining of the raw yarn Yr so that the residual elongation of the dummy jig machining yarn Yf becomes the specified target value (hereafter, referred to as the target elongation). That is, in general, the raw yarn Yr is sham-stitched taking into account the elongation before machining and the target elongation. The target elongation can be slightly different depending on the purpose of machining the thread Yf of the dummy. Typical target elongation converges in the range of 18~26%. The action conditions of the 1st feeder roller 11, the 1st heating device 13, the cooling device 14, the dummy device 15 and the 2nd feeder roller 16 are set as machining conditions in the dummy jig processing machine 1 to make the residual elongation of the dummy pinch processing yarn Yf the target elongation. For example, the aforementioned tensile ratio is determined (calculated) by the relationship between the elongation before machining and the target elongation. (Causes of Oscillations) Next, a brief explanation of the causes of oscillations is given. Oscillations are produced by accidental relaxation or tightening of the traveling thread Y repeatedly. The devices that become the direct cause of the oscillations are mainly dummy devices15. That is, oscillations may be generated between the first feeder roller 11 and the second feeder roller 16 in the direction of thread travel. For example, in a friction mode of dummy cock apparatus 15 , the traveling thread Y may slip with respect to the surface of the disk. The thread Y is able to travel normally even if it is slipping in the dummy cock apparatus 15 as long as it does not relax (i.e., continuous tension is applied to the thread Y). However, if the travel speed of the thread Y in the dummy device 15 (roughly equal to the speed of the second feed thread) becomes faster, the thread Y is prone to slipping. The higher the frequency of thread Y slipping, the higher the likelihood that thread Y will relax. Furthermore, if thread Y is accidentally relaxed or tightened between the first feeder roller 11 and the second feeder roller 16, the thread Y vibrates and cannot travel normally. that is, producing oscillations. The speed of the 2nd feed thread at the beginning of the generation of oscillations is the aforementioned limit speed. An effective method used to suppress oscillations is to increase the tension of the thread Y traveling on the immediately upstream side of the thread travel direction of the dummy cock device 15 (i.e., the machining tension). However, as mentioned above, the tensile magnification was predetermined based on the elongation before machining and the target elongation. In general, the larger the tensile magnification the machining tension may become larger, but if the tensile magnification is increased, the residual elongation of the dummy-hand machined yarn Yf is significantly different from the target elongation. Such fake fucker processing thread Yf as a product is substandard. (Method of manufacturing of dummy machining yarn) In the foregoing situation, the inventors in the present case studied methods for making dummy machining yarn Yf suitable as a product and increasing the limit speed. In this case, while changing the manufacturing conditions of raw yarn Yr in the spinning and winding equipment 100 , the inventor performs dummy processing using the raw yarn Yr manufactured under the respective manufacturing conditions. More specifically, the inventors of the present case prepared raw thread Yr of Examples 1~16 and Comparative Examples 1~13 as shown in the table of Figures 4(a) ~ 6(b) . The segmentation benchmark with respect to embodiments and comparative examples will be described later. The raw thread Yr of each embodiment and each comparative example is fabricated with a general thickness (83dtex) as the target thickness. The raw filament Yr of Examples 1~4 and Comparative Examples 1~2 (referring to FIG. 4(a) and FIG. 4(b)) is a raw filament Yr with a filament number of 48 strands. The raw filament Yr of Examples 5~12 and Comparative Examples 3~5 (referring to Figs. 5(a) and 5(b)) is a protofilament Yr with a filament number of 72 strands. The protofilament Yr of Examples 13~16 and Comparative Examples 6~13 (referring to FIG. 6(a) and FIG. 6(b)) is a protofilament Yr with a filament number of 144 strands. Figs. 4(a), 5(a) and 6(a) are tables showing the manufacturing conditions of the raw yarn Yr and the physical properties of the raw yarn Yr. As the manufacturing conditions of the raw yarn Yr, the spinning speed is shown. As the physical properties of the raw yarn Yr, the residual elongation (elongation before processing), strength, fineness, boiling water shrinkage rate, orientation degree and crystallinity are shown. The spinning speed (unit: m / min) is the winding speed of winding the yarn Y on the bobbin B. The residual elongation (unit: %) is measured using a tensile strength meter TENSORAPID (trademark) manufactured by USTER. The strength (unit: cN / dtex) is also measured using a tensile strength meter TENSORAPID manufactured by USTER. After obtaining a yarn sample of a specified length using an electric length measuring machine (equipment for reeling the yarn) manufactured by INTEC, the weight of the yarn sample is measured using a general weighing scale. Therefore, the ratio of the weight and length of the yarn sample is calculated as the fineness. The unit of fineness is dtex. A yarn sample of a specified length is heated by a constant temperature bath (model T-22H) manufactured by Thomas Scientific Instruments Co., Ltd., and the length of the yarn after heating is measured using a general ruler, and thus the boiling water shrinkage rate (unit: %) is calculated. The orientation degree (dimensionless quantity) is measured using a Raman spectroscopic device RAMAN touch (registered trademark) manufactured by Nanophoton. The crystallinity (unit: %) is measured using a differential scanning calorimeter DSC25 (model) manufactured by TA Instruments. In addition, as an index of the orientation degree of the material constituting the yarn Y, the birefringence is generally measured. Instead of measuring the birefringence, the inventor of the present case measured the orientation degree using Raman spectroscopy. In addition, the orientation degree and crystallinity were only measured in Examples 1 to 4 and Comparative Examples 1 to 2 for reference. In this case, the inventors perform a conditional assignment of the residual elongation of raw yarn Yr obtained from the spinning and winding equipment 100. The PET-made (i.e., polyester-made) yarn Y manufactured under each condition is used as the raw yarn Yr. It is possible to change the residual elongation of the raw yarn Yr by changing the spinning speed of the spinning winding equipment 100 . In general, the faster the winding speed, the easier it is for the molten polymer spun from the spinning device 101 to be stretched during the period prior to curing. Therefore, there is a tendency that the faster the winding speed is the lower the residual elongation of the original filament Yr. In this case, the inventors prepared as a plurality of types of raw yarn Yr with a residual elongation of 100% or more and a raw yarn Yr with a residual elongation of less than 100%. Raw silk Yr with residual elongation of 100% or more was previously generally considered suitable for tensile dummy processing. On the other hand, raw thread Yr with residual elongation less than 100% was previously generally considered unsuitable for tensile dummy processing. In this case, the inventors set the manufacturing conditions other than the spinning speed at the time of manufacturing each raw yarn Yr as common and general manufacturing conditions. In other words, at least the general dummy machining can be implemented for previous raw thread Yr with a residual elongation of 100% or more. In addition, the strength of the ast yarn Yr with a residual elongation of less than 100% was higher than that of the ast yarn Yr with a residual elongation of more than 100%, above 2.9cN / dtex. In this case, the inventor set the manufacturing conditions for the machining yarn Yf (machining conditions), taking into account the residual elongation of the raw yarn Yr before machining (preceding elongation before machining) and the target elongation. The target elongation was 22% under all dummy machining conditions. Figure 4(b) , Figure 5(b) and Figure 6(b) are tables showing the machining conditions of the dummy during fabrication of each dummy machining thread Yf, the machinability during dummy machining and the physical properties of the dummy machining yarn Yf. As a dummy machining condition, the aforementioned tensile magnification is shown. As machinability, the limit speed (described later) and machining tension are shown. As the physical properties of the dummy machining yarn Yf, the residual elongation and strength of the dummy machining yarn Yf are shown. The machining tension (in cN) was determined using a general tensiometer. The residual elongation and strength of the dummy-handled processing yarn Yf were determined by resorting to the same apparatus as the apparatus for determining the residual elongation and strength of the original yarn Yr. In this case, the inventors set dummy machining conditions other than the tensile magnification as common and general dummy machining conditions. It follows that at least during dummy processing of raw yarn Yr with residual elongation of more than 100%, previous good quality dummy machining yarn Yf can be obtained. In the present case, the inventor produced the dummy machining yarn Yf under the processing conditions corresponding to the respective raw yarn Yr. Further, the inventor in the present case confirms the limit speed by gradually increasing the machining speed while maintaining the condition of the aforementioned tensile magnification while manufacturing the various dummy pinch machining yarn Yf. The highest machining speed among the machining speeds that did not produce oscillations was the limiting speed under the respective dummy-pin machining condition (hereafter, referred to as the condition). The previous limit speed during dummy machining of the usual raw thread Yr was up to approximately 1000m / min. Under certain conditions, the results of machining speeds far exceeding previous limit speeds were obtained. In this case, the inventors classify the examples of each condition into embodiments and comparative examples. More specifically, in this case the inventors classify as embodiments examples of conditions where the limit speed is above 1100m / min under conditions unrelated to the number of filaments of raw thread Yr, residual elongation of raw thread Yr less than 100%, normal processing of thread Yf, and normal thread quality of thread Yf. Furthermore, the inventors herein classify conditions other than those as comparative examples. That is, the inventors of the present case set as embodiments an example of a condition that purely raises the limit speed compared to the previous ones. This is a segmentation benchmark for embodiments and comparative examples of the present embodiment. Normally carried out dummy crotch processing more specifically means that problems such as fluffing or thread breakage have not been produced in dummy crotch processing. Hairiness is poor thread quality resulting from the breakage of only a portion of the plurality of filaments that make up thread Y . Broken thread is an undesirable condition in which thread Y is completely disconnected and the manufacturing of fake fucker processing thread Yf is stopped. In this embodiment, no linting or broken threads in dummy processing are produced in either embodiment and comparative embodiments, and dummy processing is normally performed. The normal strand quality of the dummy-handled processed yarn Yf More specifically means that the residual elongation and strength of the dummy-handled-processed yarn Yf are approximately the same degree as before. In the present case, the inventors judged the dummy machining yarn Yf with a residual elongation of 18~26% and a strength of 3.7 or more as a dummy machined yarn Yf of normal yarn quality. As shown in Fig. 4(a) ~ Fig. 6(b) , the result of a dramatic increase in the limit speed of the sham machining was found when the raw thread Yr with elongation less than 100% before machining (i.e., previously considered unsuitable for tensile dummy machining) was performed. Regarding the reasons for obtaining such a result, the inventors of the present case examine as follows. First, as mentioned above, the faster the winding speed of the spinning winding equipment 100 , the lower the residual elongation of the raw yarn Yr. The lower residual elongation means that the raw yarn Yr fabricated from the spinning winding equipment 100 is stretched more. If the protofilament Yr is stretched, the orientation of the polymers contained in the protofilament Yr is consistent (polymer orientation). In addition, with the orientation of the polymer, the crystallization of the polymer progresses. The inventors in this case believe that there is some causal relationship between these phenomena and the increase in the limit speed of dummy machining. Further, the inventors consider the situation where as the molecular configuration of the protofilament Yr has the following three configurations, the mixing ratio of these three configurations in the protofilament Yr (hereafter, referred to as the composition ratio) differs depending on the spinning speed. Refer to Figure 7 for a more specific explanation. 7 is a graph showing the relationship between the composition ratio and spinning speed of the molecular configuration of the protofilament Yr. The vertical axis indicates the composition ratio. The horizontal axis indicates the spinning speed. The protofilament Yr as the 1st configuration can comprise a configuration of unoriented and uncrystallized non-oriented amorphous matter of the polymer (hereafter, referred to as configuration S1). The protofilament Yr as a 2nd configuration can comprise a configuration of polymer-oriented but uncrystallized oriented amorphous (hereafter, referred to as configuration S2). The protofilament Yr as a 3rd configuration can comprise a configuration of polymer-oriented and crystallized oriented crystalline matter (hereafter, referred to as configuration S3). Constructs S1, S2, and S3 are delineated by solid lines within the graph of Fig. 7 . In addition, the likelihood that the configuration of the polymer unoriented but crystallized non-oriented crystalline material is included in the protofilament Yr is not zero. However, in the spinning and winding equipment 100 , the protofilament Yr travels while being stretched to some extent, and thus, the likelihood of a configuration of non-oriented crystalline matter being included in the protofilament Yr is substantially very low. Therefore, the explanation of the construct is omitted here. As shown in Fig. 7 , configuration S1 occupies the majority of the original yarn Yr under conditions of very low spinning speed (referring to the double dotted line L1). In the raw yarn Yr with a slightly higher spinning speed, the proportion of conformation S2 becomes more and the proportion of conformation S1 becomes less (referring to the double dotted line L2). In the raw yarn Yr, which has a higher spinning rate, the configuration S3 begins to appear (refer to the double dotted line L3). In the raw yarn Yr with higher spinning speed, the proportion of constructs S3 becomes more and the proportions of constructs S1 and S2 become less (refer to double dotted dash L4). In protofilament Yr with higher spinning speed, configuration S3 occupies the majority of protofilament Yr (refer to double dotted dash L5). The part of configuration S2 (orientated amorphous) of the protofilament Yr generally resorts to heating and readily returns to configuration S1 (non-oriented amorphous), which may generate greater heat contraction forces due to the relaxation of orientation upon heating. On the other hand, parts of the configuration S3 (orientated crystalline matter) of the protofilament Yr are generally difficult to cause a change in configuration due to heating and therefore to generate heat contraction forces. However, the part of the configuration S3 has higher stiffness and is prone to stress generation when external force is applied. In the present case, the inventors believe that these characteristics are intricately related to each other, the machining tension varies according to the pre-machining elongation of the raw thread Yr, and as a result, the limit speed of the dummy machining changes. In this embodiment, more raw silk Yr is fabricated at a higher spinning rate. Therefore, there are fewer parts of conformation S1 and conformation S2 and more parts of conformation S3 in the plural number of protofilaments Yr. Therefore, in addition to the pre-processing elongation of the protofilament Yr, the inventors in the present case focused on the ratio of the portion of amorphous material (part of configuration S1 or configuration S2) to the portion of crystalline matter (part of configuration S3) in the protofilament Yr. As one of the physical properties of raw silk Yr that significantly reflects this ratio, the boiling water shrinkage rate can be cited. The correlations between various items are illustrated with reference to the graphs in Figures 8(a)~11(b). Figure 8(a) is a graph showing the correlation between the limit velocity of the dummy pin machining and the residual elongation of the protofilament Yr. Figure 8(b) is a graph showing the correlation between the limit velocity and the machining tension for dummy-stitch machining. Figure 9(a) is a graph showing the correlation between the limit speed of the dummy clutch processing and the boiling water shrinkage rate of the raw yarn Yr. Figure 9(b) is a graph that enlarges part of Figure 9(a). Figure 10(a) is a graph showing the correlation between the boiling water shrinkage of the protofilament Yr and the residual elongation of the protofilament Yr. Figure 10(b) is a graph showing the correlation between the residual elongation of the raw yarn Yr and the spinning speed of the raw yarn Yr. Figure 11(a) is a reference graph showing the correlation between the limit velocity of dummy pin processing and the orientation of the protofilament Yr. In Fig. 11(a) , the correlation between the limit velocity of dummy-stitch processing and the orientation of the protofilament Yr is presumed by resorting to interpolation (referring to the dashed line). Fig. 11(b) is a reference graph showing the correlation between the limit velocity of the dummy pin processing and the crystallinity of the protofilament Yr. In Fig. 11(b) , the correlation between the limit velocity of the pseudo-pin processing and the crystallinity of the protofilament Yr is presumed by resorting to interpolation (referring to the dashed line). As shown in Figure 8(a) , the limit speed is highest when the elongation of the raw thread Yr before machining is about 90~100%. In the region where the elongation before machining is less than 90%, there is a tendency that the lower the elongation before machining, the lower the limit speed. Furthermore, if the elongation before machining is less than 80%, there is a tendency for the limit speed to be less than 1100m / min. However, the elongation before machining with the largest limit speed produces a deviation according to the number of filaments of the raw yarn Yr. Therefore, the inventors in the present case examined that an elongation of 80% or more before machining is not a necessary condition used to make the limit speed above 1100m / min. Furthermore, as shown in Fig. 8(b) , there is a tendency to roughly become higher in the limit speed at large machining tensions. The tendency and the foregoing investigations related to the limit velocity are broadly consistent. However, if the machining tension is too large, there is a tendency for the limit velocity to begin to decrease. Therefore, the inventors in the present case examined that the limit speed is not determined by machining tension alone. As shown in Fig. 9(a) , the limit velocity reaches its maximum when the boiling water shrinkage of the original filament Yr is about 10%. In general, the more progressive the crystallization of the original silk Yr, the higher the boiling water shrinkage. The foregoing tendencies with respect to limit velocities do not depend substantially on the number of filaments of the original filament Yr. Therefore, the inventors of the present case examined that the boiling water shrinkage rate is a very large cause used to determine the limit velocity. According to Figs. As a reference, as shown in Fig. 10(a) , there is a tendency that the greater the boiling water shrinkage of the raw thread Yr the higher the residual elongation (elongation before processing). The tendency is a general tendency to mean that the more portions of configuration S3 in the protofilament Yr the more difficult it is for the protofilament Yr to stretch. Accordingly, at boiling water shrinkage of less than about 25%, the elongation before processing forms less than 100%. As a reference, as shown in Fig. 10(b) , there is a tendency that the higher the spinning speed of the raw yarn Yr then the lower the residual elongation of the raw yarn Yr (elongation before processing). However, the specific relationship between spinning speed and elongation before processing differs according to the number of filaments of the raw thread Yr. Therefore, based on that graph, it was speculated that the spinning speed and the elongation before processing were not determinants of the limit speed. As a reference, as shown in Fig. 11(a) , in order to make the limit speed above 1100m / min, the orientation of the original thread Yr is ideally above 1.23 and below 1.38. As a reference, as shown in Fig. 11(b) , in order to make the limit speed above 1100m / min, the crystallinity of the original filament Yr is ideally 26% or less than 38%. Based on the above, it is considered that the sum of the thermal contraction force due to the relaxation of the orientation of the crystals of the raw yarn Yr and the resistance of the raw yarn Yr to stretching is greater in the raw yarn Yr whose elongation is less than 100% before processing. Therefore, the machining tension applied to the raw strand Yr becomes larger when the pre-machining elongation of the raw yarn is less than 100% and the boiling water shrinkage is less than 25%. Therefore, even increasing the speed of the 2nd feed thread can suppress the relaxation of thread Y. Therefore, it is able to suppress the generation of oscillations. On the other hand, if the boiling water shrinkage is too low (i.e., if the crystallization of the original thread Yr progresses excessively), the torsional stress generated when the thread Y is sham-pinned becomes larger. If the torsional stress is too large, the elastic restoring force for the twisted thread Y becomes too large, and therefore, the thread Y in the dummy jig apparatus 15 is prone to slipping in the torsional direction. Therefore, in order to suppress the slippage of thread Y by suppressing torsional stress, the boiling water shrinkage rate to some extent (more than 3.7%, specifically) is required. According to the above, the limit speed is dramatically improved by using partially oriented threads composed of synthetic fibers made of PET with elongation less than 100% and boiling water shrinkage of 3.7% or less than 25% before processing as raw thread Yr. More specifically, the generation of oscillations can be suppressed even if the processing speed is set above 1100m / min. The boiling water shrinkage of raw silk Yr is ideally 3.7% or more or less than 10%. Therefore, it is able to increase the aforementioned resistance. In addition, partially oriented threads with elongation less than 100% before machining were previously considered to be prone to fluffing or breakage and were considered unsuitable for tensile dummy processing. Despite this, in embodiments, no fluffing and thread breakage was produced. One of the reasons is that the strength of the raw thread Yr before processing of the fake cock is as high as 2.9cN / dtex or more. Therefore, even if the tension applied to the raw thread Yr is greater, the strength of the raw thread Yr before dummy processing is required to be above 2.9cN / dtex in order to prevent the generation of puffing or breakage. In addition, the elongation before machining is ideally 80% or more. The target elongation is ideally 18% or more or less than 26%. In addition, the orientation of raw silk Yr before dummy processing was ideally determined using Raman spectroscopic apparatus. In addition, the crystallinity of raw silk Yr is ideally 26% or more or less than 38%. As mentioned above, the raw yarn Yr with elongation less than 100% before processing and boiling water shrinkage of 3.7% or less than 25% was processed for dummy pin processing. Therefore, the machining tension becomes larger. Therefore, it was able to inhibit silk Y relaxation. Therefore, it is able to suppress the generation of oscillations. Furthermore, because the strength of the protofilament Yr is as high as above 2.9cN / dtex, the disconnection of the protofilament Yr can be inhibited even if the tension applied to the protofilament Yr becomes larger. Therefore, it is able to inhibit the production of hair lifting and / or thread breakage. According to the above, the limit speed of the thread Yf that enables the production of fake cock processing threads can be improved. In addition, the limit velocity may be reduced if the elongation before machining is too low. Therefore, the elongation before machining is ideally 80% or more. In addition, the boiling water shrinkage of raw silk Yr is ideally 3.7% or less than 10%. Therefore, it is able to increase the aforementioned resistance. Therefore, it is able to increase the machining tension. In addition, the orientation of the protofilament Yr determined using Raman spectrophotometry was above 1.23 and below 1.38. In this way, since the degree of orientation is not too high or too low, it is able to increase the machining tension and suppress the aforementioned torsional stress from becoming excessive. In addition, the crystallinity of the raw silk Yr was more than 26% and less than 38%. In this way, since the crystallinity is not too high or too low, it is able to increase the machining tension and suppress the aforementioned torsional stress from becoming excessive. In addition, the target elongation is more than 18% and less than 26% Therefore, it is possible to fabricate dummy machining thread Yf with a general residual elongation.
