[0002] In recent years, textile structures made of a weave (fabric) in which a plurality of fibers are woven together have become known, such as work belts, camping hanging chains, clothing fabrics, etc. Such textile structures have a configuration in which a plurality of weaves, each made of a plurality of warp threads and a plurality of weft threads entangled with each of the plurality of warp threads, are laminated together.

[0003] For example, Patent Document 1 discloses a woven fabric structure in which at least two or more woven fabrics are laminated, each woven with a first fiber containing a metal as a warp thread and a second fiber having greater flexibility than the first fiber as a weft thread, and the warp or weft threads of each woven fabric are oriented in different directions when the laminated woven fabrics are viewed in the lamination direction. In this woven fabric structure, the woven fabrics are connected to each other by being fixed to each other. [Prior art documents] [Patent documents]

[0015] 1. Embodiment <<First embodiment>> <Manufacturing system configuration> 1 is a block diagram showing an example of the configuration of a manufacturing system 100 for a woven fabric structure according to this embodiment. The manufacturing system 100 includes an information processing device 10 and a weaving machine 20.

[0016] [Information processing device] The information processing device 10 has a CPU (Central Processing Unit) 101, a ROM (Read Only Memory) 102, and a RAM (Random Access Memory) 103. The information processing device 10 may also have a host bus 104, a bridge 105, an external bus 106, an interface 107, an input device 108, an output device 109, a storage device 110, a drive 111, a connection port 112, and a communication device 113. Instead of or in addition to the CPU 101, the information processing device 10 may have a processing circuit such as a DSP (Digital Signal Processor), an ASIC (Application Specific Integrated Circuit), or an FPGA (Field-Programmable Gate Array).

[0017] The CPU 101 functions as an arithmetic processing device and / or a control device, and controls the overall operation or a part of the operation of the information processing device 10 and the weaving device 20 in accordance with various programs recorded in the ROM 102, the RAM 103, the storage device 110, or the removable recording medium 114. The CPU 101 executes a program P1 based on a pick diagram (see FIG. 5) described later, which is stored in the ROM 102, the RAM 103, the storage device 110, or the removable recording medium 114, to thereby control a manufacturing method for a woven structure (steps S a 1 to 3) are executed by the weaving device 20. The program P1 may be a program pre-recorded in the ROM 102, the RAM 103, the storage device 110, or the removable recording medium 114, or may be a program downloaded from a server device such as an external server or a cloud server via the network NW.

[0018] ROM 102 stores programs and computation parameters used by CPU 101. RAM 103 temporarily stores programs used by CPU 101 during execution and parameters that change as appropriate during execution. CPU 101, ROM 102, and RAM 103 are interconnected by host bus 104, which is an internal bus such as a CPU bus. Furthermore, host bus 104 is connected to external bus 106, such as a PCI (Peripheral Component Interconnect / Interface) bus, via bridge 105.

[0019] The input device 108 is a device operated by an operator, such as a mouse, a keyboard, a touch panel, a button, and a switch. The input device 108 may be, for example, a remote control device that uses infrared rays or other radio waves. The input device 108 includes an input control circuit that generates an input signal based on information input by the operator and outputs the signal to the CPU 101. By operating the input device 108, the operator inputs various data to the information processing device 10 and instructs the loom device 20 to perform processing operations via the information processing device 10.

[0020] The output device 109 is configured with a device capable of notifying the operator of acquired information using senses such as vision, hearing, or touch. The output device 109 may be, for example, a display device such as an LCD (Liquid Crystal Display) or an organic EL (Electro-Luminescence) display, or an audio output device such as a speaker. The output device 109 may output the result obtained by the processing of the information processing device 10 as a video such as text or an image, or as a sound such as voice or audio.

[0021] The storage device 110 is a data storage device configured as an example of a storage unit of the information processing device 10. The storage device 110 is configured, for example, with a magnetic storage device such as a hard disk drive (HDD), a semiconductor storage device, an optical storage device, or a magneto-optical storage device. The storage device 110 stores, for example, programs and various data executed by the CPU 101, and various data acquired from the outside.

[0022] The drive 111 is a reader / writer for a removable recording medium 114 such as a magnetic disk, an optical disk, a magneto-optical disk, or a semiconductor memory, and is built into or externally attached to the information processing device 10. The drive 111 reads out information recorded on the attached removable recording medium 114 and outputs the information to the RAM 103. The drive 111 also writes information onto the attached removable recording medium 114.

[0023] The connection port 112 is a port for connecting a device to the information processing device 10. The connection port 112 is not particularly limited, and may be, for example, a Universal Serial Bus (USB) port, an IEEE1394 port, a Small Computer System Interface (SCSI) port, an RS-232C port, etc. By electrically connecting the weaving device 20 to the connection port 112, various types of data are exchanged between the information processing device 10 and the weaving device 20.

[0024] The communication device 113 is, for example, a communication interface configured with a communication device for connecting to a network NW. The communication device 113 may be, for example, a communication card for a LAN (Local Area Network), Bluetooth (registered trademark), Wi-Fi, or WUSB (Wireless USB). The communication device 113 may also be a router for optical communication, a router for an ADSL (Asymmetric Digital Subscriber Line), or a modem for various communications. The communication device 113 transmits and receives signals, for example, between the Internet and other communication devices using a predetermined protocol such as TCP / IP. The network NW connected to the communication device 113 is a network connected by wire or wirelessly, for example, the Internet, a home LAN, infrared communication, radio wave communication, or satellite communication.

[0025] The information processing device 10 is not particularly limited, and may be, for example, a personal computer, a server device, a laptop computer, a smartphone, or a tablet terminal.

[0026] [Loom equipment] The weaving apparatus 20 is a needle loom that manufactures a woven fabric structure by vertically moving each of a plurality of heald frames (not shown) corresponding to each of a plurality of warp threads (a to e) and repeating the operation of passing weft threads (weft threads A and B) between the warp threads via needles (cross needles) at high speed in accordance with program control of the information processing apparatus 10 based on the program P1. Specifically, the weaving apparatus 20 is, for example, a two-strand electronic dobby high-speed needle loom (model number: NFRE-42·2 / 84EDZ10S3, manufactured by Jakob Muller AG).

[0027] <Textile structure> Next, a description will be given of the woven fabric structure 1 manufactured by the manufacturing method for a woven fabric structure according to the present embodiment.

The woven structure 1 has an upper layer 11 (first layer), a lower layer 12 (second layer), and a plurality of warp threads e (third warp threads). As shown in Fig. 2, the woven structure 1 is provided with a plurality of openings 13. The openings 13 are portions of the woven structure 1 where the upper layer 11 and the lower layer 12 are not bound by the warp threads e and can be separated from each other. As shown in the figure, the plurality of openings 13 are provided intermittently in the X-axis direction.

[0029] The dimension (width) of the woven structure 1 in the Y-axis direction is not particularly limited, but is preferably, for example, 10 mm or more and 80 mm or less. The thickness of the woven structure 1 is also not particularly limited, but is preferably, for example, 1 mm or more and 7 mm or less. The woven structure 1 is used, for example, as a hanging chain or a work belt, but the uses of the woven structure 1 are not limited thereto.

[0030] [Upper layer] Fig. 3 is a perspective view showing the structure of the upper layer 11. As shown in Fig. 3, the upper layer 11 has a plain weave structure of a portion A1 of the weft thread A (first weft thread) that extends in the Y-axis direction and is spaced apart in the X-axis direction, and a plurality of warp threads a, b (first warp threads) that extend in the X-axis direction. Note that, although each of the plurality of portions A1 is shown separately in Fig. 3, the weft thread A is a thread in which the plurality of portions A1 are connected in a continuous manner.

[0031] [Lower layer] Fig. 4 is a perspective view showing the structure of the lower layer 12. As shown in Fig. 4, the lower layer 12 has a plain weave structure of a portion B1 of the weft yarn B (second weft yarn) that extends in the Y-axis direction and is spaced apart in the X-axis direction, and a plurality of warp yarns c, d (second warp yarns) that extend in the X-axis direction. Note that, although each of the plurality of portions B1 is shown separately in Fig. 4, the weft yarn B is a yarn in which the plurality of portions B1 are connected in a continuous manner.

[0032] [Warp thread e] The multiple warp threads e extend in the X-axis direction and are spaced apart in the Y-axis direction. The multiple warp threads e are binding threads that intermittently bind the upper layer 11 and the lower layer 12 by being entangled with the portion A1 of the weft thread A and the portion B1 of the weft thread B (see FIG. 6).

[0049] (Operation M a~e 4,8,10,14,16,18) The loom device 20 operates M a~e In 4, the above operation m a,b 4,m c,d 4 and m e 6, the needles of the loom apparatus 20 carry out the wefts A and B in the Y1 direction, pass the weft A under each of the warp threads b and over each of the warp threads a, c, d, and e, and pass the weft B under each of the warp threads a, b, d, and e and over each of the warp threads c. The loom apparatus 20 performs this operation as operation M. a~e The same is true for steps 8, 10, 14, 16, and 18. a~e 8. M a~e 10. M a~e 14.

[0050] In this embodiment, the number of warp threads c and d corresponding to the lower layer 12 may be greater than the number of warp threads a, b, and warp thread e corresponding to the upper layer 11. In this case, the weaving machine 20 performs the above step S a2, for example, the operator of the manufacturing system 100 may set the conveyance amount (e.g., conveyance speed) per unit time of the weft yarn B in the Y-axis direction to be greater than the conveyance amount (e.g., conveyance speed) per unit time of the weft yarn A in the Y-axis direction, thereby manufacturing a woven structure 1 in which the dimension (width) of the lower layer 12 in the Y-axis direction is greater than the dimension (width) of the upper layer 11 in the Y-axis direction, as shown in FIG. 7. In the woven structure 1, as shown in the figure, the width of the upper layer 11 at the opening 13 of the woven structure 1 is smaller than the width of the lower layer 12. As a result, when the woven structure 1 is used as, for example, a hanging chain or a work belt, it becomes easier to hang an object on the opening 13 compared to when the width of the upper layer 11 is equal to the width of the lower layer 12, and the convenience of the woven structure 1 is improved. Note that, in the woven structure 1, the side surface of the upper layer 11 located in the Y2 direction and the side surface of the lower layer 12 located in the Y2 direction are flush with each other due to the specifications of the weaving machine 20.

[0051] As described above, the method for manufacturing the woven fabric structure 1 according to the present embodiment includes an upper layer 11 having a weave structure of a weft yarn A extending in the Y-axis direction and having a portion A1 spaced apart in the X-axis direction, and a plurality of warp yarns a and b extending in the X-axis direction, a lower layer 12 having a weave structure of a weft yarn B extending in the Y-axis direction and having a portion B1 spaced apart in the X-axis direction, and a plurality of warp yarns c and d extending in the X-axis direction, and a plurality of warp yarns e extending in the X-axis direction and spaced apart in the Y-axis direction, the plurality of warp yarns e binding the upper layer 11 and the lower layer 12, and the openings 13 separating the upper layer 11 and the lower layer 12 are intermittently provided in the X-axis direction, and includes a step S of entangling the weft yarn A with the plurality of warp yarns a and b. a 1, and step S in which the weft thread B is entangled with multiple warp threads c and d. a 2, and step S in which weft threads A and B are entangled with multiple warp threads e. a 3 and 4 are executed in parallel by the weaving device 20.

[0052] According to the above embodiment, the weaving apparatus 20 executes in parallel the process of creating the upper layer 11 and the lower layer 12 and the process of binding the upper layer 11 and the lower layer 12 in the middle of being created. That is, the weaving apparatus 20 binds the upper layer 11 and the lower layer 12 in the middle of being created while creating the upper layer 11 and the lower layer 12. In this way, the woven fabric structure 1 performs the above step S a 1~S a At the stage where the weaving machine 20 is completed through step 3, the upper layer 11 and the lower layer 12 are already bound together. Therefore, a separate step of binding the upper layer 11 and the lower layer 12 together is not required to obtain the woven fabric structure 1, and the loom apparatus 20 can manufacture the woven fabric structure 1 at lower cost and in a shorter time than in the past.

[0053] <<Second embodiment>> Next, a second embodiment of the present invention will be described. In the following description of the second embodiment, the same configurations, steps, functions, etc. as those of the first embodiment are denoted by the same reference numerals, and the description thereof may be omitted or simplified.

[0054] <Information processing device> The CPU 101 according to the second embodiment executes a program P2 based on a pick diagram (see FIG. 9) described later, which is stored in the ROM 102, the RAM 103, the storage device 110, or the removable recording medium 114, to perform a method for manufacturing a woven structure (step S a 1,S a 2,S b 3) is executed by the weaving device 30 of the second embodiment. The program P2 may be a program pre-recorded in the ROM 102, the RAM 103, the storage device 110, or the removable recording medium 114, or may be a program downloaded from a server device such as an external server or a cloud server via the network NW.

[0055] <Loom equipment> The weaving apparatus 30 according to the second embodiment is a needle loom that manufactures a woven fabric structure by vertically moving each of a plurality of heald frames (not shown) corresponding to each of a plurality of warp threads (a plurality of warp threads a to f) and repeating the operation of passing weft threads (weft threads A and B) between the warp threads via needles (cross needles) at high speed in accordance with program control of the information processing device 10 based on the program P2. Specifically, the weaving apparatus 30 is, for example, a two-strand electronic dobby high-speed needle loom (model number: NFRE-42·2 / 84EDZ10S3, manufactured by Jakob Muller AG).

[0056] <Configuration of woven structure> Next, the configuration of a woven fabric structure 2 manufactured by the manufacturing method for a woven fabric structure according to the second embodiment will be described.

[0057] Fig. 7 is a perspective view showing a configuration example of the woven structure 2. The woven structure 2 has an upper layer 11 (first layer), a lower layer 12 (second layer), and a plurality of warp threads e, f (third warp threads). As shown in Fig. 8, the woven structure 2 is provided with a plurality of openings 23. The openings 23 are portions of the woven structure 2 where the upper layer 11 and the lower layer 12 are separated from each other because they are not bound by the warp threads e, f. As shown in the same figure, the plurality of openings 23 are provided intermittently in the X-axis direction.

[0058] The dimension (width) of the woven structure 2 in the Y-axis direction is not particularly limited, but is preferably, for example, 10 mm or more and 80 mm or less. The thickness of the woven structure 2 is also not particularly limited, but is preferably, for example, 1 mm or more and 7 mm or less. The woven structure 2 is used, for example, as a hanging chain or a work belt, but the uses of the woven structure 2 are not limited thereto.

[0059] [Warp threads e, f] The multiple warp threads e and f extend in the X-axis direction and are spaced apart in the Y-axis direction. The warp threads e and f are entangled with the portions A1 and B1 of the weft threads A and B in different ways (see FIG. 10). The warp threads e and f are binding threads that intermittently bind the upper layer 11 and the lower layer 12 by being entangled with the portion A1 of the weft thread A and the portion B1 of the weft thread B.

[0060] <Method of manufacturing woven fabric structure> Next, a method for manufacturing a woven fabric structure according to the second embodiment will be described. The manufacturing method is a method for manufacturing a woven fabric structure 2 including an upper layer 11 having a weave structure of a weft thread A extending in the Y-axis direction and having a portion A1 spaced apart in the X-axis direction, and a plurality of warp threads a and b extending in the X-axis direction, a lower layer 12 having a weave structure of a weft thread B extending in the Y-axis direction and having a portion B1 spaced apart in the X-axis direction, and a plurality of warp threads c and d extending in the X-axis direction, and a plurality of warp threads e and f extending in the X-axis direction and spaced apart in the Y-axis direction, which bind the upper layer 11 and the lower layer 12, and in which openings 23 separating the upper layer 11 and the lower layer 12 are intermittently provided in the X-axis direction, and includes a step S of entangling the weft thread A with the plurality of warp threads a and b. a 1 (first step), and step S in which weft thread B is entangled with multiple warp threads c and d. a 2 (the second step), and step S in which weft threads A and B are entangled with multiple warp threads e and f. b 3 (third step) are executed in parallel by the weaving machine 30. b Let me explain 3.

[0061] [Step S b 3] The weaving machine 30 of the second embodiment is a step S b In step 3, a predetermined pattern (third pattern) is repeatedly executed, which is a rule for how the wefts A and B are entangled with the multiple warp threads e and f. The pattern is composed of 22 operations for entangling the wefts A and B with the multiple warp threads e and f. The loom device 30 executes the operations m e,f 1~m e,f 22 are executed in order. e,f 1~m e,f I will explain about 22.

[0062] (m e,f 1,3,5,7,9,11,13,15,17,19,21) The needles of the loom device 30 are moved e,fIn the weaving machine 1, wefts A and B are passed under each of a plurality of warp threads e along the Y-axis direction, and wefts A and B are passed over each of a plurality of warp threads f. The weaving machine 30 performs this operation as an operation m e,f Do the same for 3, 5, 7, 9, 11, 13, 15, 17, 19, and 21.

The loom apparatus 20 of the second embodiment performs this operation as an operation m e,f Do the same for 8, 10, 14, 16, and 18. In the second embodiment, the operator of the manufacturing system 100 may change the program P2 to change the way in which the wefts A and B are entangled with the warps e and f, thereby changing the size of the opening 23 of the woven fabric structure 2. Specifically, for example, the above operation m may be changed in accordance with the operator's change of the program P2. e The size of the opening 23 may be changed by increasing or decreasing the number of times the operation of passing the weft A above and the weft B below each of the multiple warp threads e and f corresponding to 4, 8, 10, 14, 16, and 18 is performed. This allows the operator to set the size of the opening 23 in the X-axis direction to a desired size, and enables the manufacture of various woven structures 2 each having a different size.

[0065] [Loom device operation] FIG. 9 is a pick diagram showing the vertical positional relationship of warp threads a, b, e, and f relative to weft thread A, and the vertical positional relationship of warp threads c, d, e, and f relative to weft thread B.

[0069] (Operation M a~f 2,6,12,20,22) The loom device 30 operates M a~f In 2, the above operation m a,b 2, m c,d 2 and m e,f 10, the needles of the loom apparatus 30 transport the wefts A and B in the Y1 direction, pass the weft A below each of the warp threads b and f and vertically above each of the warp threads a, c, d, and e, and pass the weft B below each of the warp threads a, b, d, and f and above each of the warp threads c and e. The loom apparatus 30 performs this operation as operation M. a~f The same is true for 6, 12, 20, and 22. a~f 6. M a~f 12. M a~f 20, M a~f 22, respectively, a,b 6,m c,d 6 and m e,f 6, m a,b 12,m c,d 12 and m e,f 12, m a,b 20,m c,d 20 and m e,f 20, m a,b 22,m c,d 22 and m e,f 22 are carried out in parallel by the weaving machine 30.

[0070] (Operation M a~f 4,8,10,14,16,18) The loom device 30 operates M a~f In 4, the above operation m a,b 4, m c,d 4 and m e,f 10, the needles of the loom device 30 carry out the wefts A and B in the Y1 direction, pass the weft A under each of the warp threads b and over each of the warp threads a, c to f, and pass the weft B under each of the warp threads a, b, d to f and over each of the warp threads c. The loom device 30 performs this operation as operation M. a~f The same is true for steps 8, 10, 14, 16, and 18. a~f 8. M a~f 10. M a~f14.

[0071] In the second embodiment, the number of warp threads c and d corresponding to the lower layer 12 may be greater than the number of warp threads a and b and warp threads e and f corresponding to the upper layer 11. In this case, the loom apparatus 30 performs the above step S a 2, for example, the operator of the manufacturing system 100 may set the conveyance amount (e.g., conveyance speed) of the weft yarn B per unit time in the Y-axis direction to be greater than the conveyance amount (e.g., conveyance speed) of the weft yarn A per unit time in the Y-axis direction, thereby manufacturing a woven structure 2 in which the dimension (width) of the lower layer 12 in the Y-axis direction is greater than the dimension (width) of the upper layer 11 in the Y-axis direction, as shown in FIG. 11. In the woven structure 2, as shown in the figure, the width of the upper layer 11 at the opening 23 of the woven structure 2 is smaller than the width of the lower layer 12. As a result, when the woven structure 2 is used as, for example, a hanging chain or a work belt, it becomes easier to hang an object on the opening 23 compared to when the width of the upper layer 11 is equal to the width of the lower layer 12, and the convenience of the woven structure 2 is improved. In addition, in the woven structure 2, the side surface of the upper layer 11 located in the Y2 direction and the side surface of the lower layer 12 located in the Y2 direction are flush with each other due to the specifications of the weaving machine device 30.

[0072] As described above, the method for manufacturing the woven fabric structure 2 according to the second embodiment is a method for manufacturing a woven fabric structure including an upper layer 11 having a weave structure of a weft yarn A extending in the Y-axis direction and having a portion A1 spaced apart in the X-axis direction, and a plurality of warp yarns a and b extending in the X-axis direction, a lower layer 12 having a weave structure of a weft yarn B extending in the Y-axis direction and having a portion B1 spaced apart in the X-axis direction, and a plurality of warp yarns c and d extending in the X-axis direction, and a plurality of warp yarns e and f extending in the X-axis direction and spaced apart in the Y-axis direction, the plurality of warp yarns e and f binding the upper layer 11 and the lower layer 12, and in which openings 23 separating the upper layer 11 and the lower layer 12 are intermittently provided in the X-axis direction, and a step S of entangling the weft yarn A with the plurality of warp yarns a and b a 1, and step S in which the weft thread B is entangled with multiple warp threads c and d. a 2, and step S in which weft threads A and B are entangled with multiple warp threads e and f. b 3 and 4 are executed in parallel by the weaving device 30.

[0073] According to the above embodiment, the weaving apparatus 30 executes, in parallel, the step of producing the upper layer 11 and the lower layer 12 and the step of binding the upper layer 11 and the lower layer 12 in the middle of being produced. That is, the weaving apparatus 30 binds the upper layer 11 and the lower layer 12 in the middle of being produced while producing the upper layer 11 and the lower layer 12. As a result, the woven fabric structure 2 performs the above step S a 1. S a 2 and S b At the stage where the weaving machine 3 is completed, the upper layer 11 and the lower layer 12 are already bound together. Therefore, a separate step of binding the upper layer 11 and the lower layer 12 is not required to obtain the woven fabric structure 2, and the loom apparatus 30 can manufacture the woven fabric structure 2 at lower cost and in a shorter time than in the past.

[0074] <<Third embodiment>> Next, a third embodiment of the present invention will be described. In the following description of the third embodiment, the same reference numerals are used for configurations, steps, functions, etc. similar to those of the first embodiment, and the description thereof may be omitted or simplified.

[0075] <Information processing device> The CPU 101 according to the third embodiment executes a program P3 based on a pick diagram (see FIG. 13) described later, which is stored in the ROM 102, the RAM 103, the storage device 110, or the removable recording medium 114, to thereby execute a method for manufacturing a woven structure (step S c 1 to 3) are executed by the weaving device 40 of the third embodiment. The program P3 may be a program pre-recorded in the ROM 102, the RAM 103, the storage device 110, or the removable recording medium 114, or may be a program downloaded from a server device such as an external server or a cloud server via the network NW.

[0076] <Loom equipment> The weaving apparatus 40 is a needle loom that manufactures a woven fabric structure by vertically moving each of a plurality of heald frames (not shown) corresponding to each of a plurality of warp threads (a plurality of warp threads a to m) and repeating the operation of passing weft threads (weft threads A and B) between the warp threads via needles (cross needles) at high speed in accordance with program control of the information processing apparatus 10 based on the program P3. Specifically, the weaving apparatus 40 is, for example, a two-strand electronic dobby high-speed needle loom (model number: NFRE-42·2 / 84EDZ10S3, manufactured by Jakob Muller AG).

[0077] <Configuration of woven structure> Next, the configuration of a woven fabric structure 3 manufactured by the manufacturing method for a woven fabric structure according to the third embodiment will be described.

[0078] Fig. 12 is a perspective view showing a configuration example of the woven structure 3. The woven structure 3 has an upper layer 31 (first layer), a lower layer 32 (second layer), and a plurality of warp threads h (third warp threads). As shown in Fig. 12, the woven structure 3 is provided with a plurality of openings 33. The openings 33 are portions of the woven structure 3 where the upper layer 31 and the lower layer 32 are not bound by the warp threads h and can be separated from each other. As shown in the same figure, the plurality of openings 33 are provided intermittently in the X-axis direction.

[0079] The dimension (width) in the Y-axis direction of the woven fabric structure 3 is not particularly limited, but is preferably, for example, 10 mm or more and 80 mm or less. The thickness of the woven fabric structure 3 is also not particularly limited, but is preferably, for example, 1 mm or more and 7 mm or less. The woven fabric structure 3 is used, for example, as a hanging chain or a work belt, but the uses of the woven fabric structure 3 are not limited thereto.

[0080] [Upper layer] The upper layer 31 has a two-layer structure, and these layers are bound together by multiple warp threads g. The upper layer of the two layers is a weave structure of multiple parts of the weft thread A (first weft thread) that extend in the Y-axis direction and are spaced apart in the X-axis direction, and multiple warp threads a, b, e, and f that extend in the X-axis direction. The lower layer is a plain weave structure of other multiple parts of the weft thread A that extend in the Y-axis direction, are spaced apart in the X-axis direction, and are continuous with the multiple parts mentioned above, and multiple warp threads c and d that extend in the X-axis direction (see FIG. 14).

[0081] The multiple warp threads g extend in the X-axis direction and are arranged at intervals in the Y-axis direction. The multiple warp threads g are binding threads that bind the upper layer and the lower layer of the upper layer 31 by being entangled with multiple portions of the weft thread A that extend in the Y-axis direction and are arranged at intervals in the X-axis direction and multiple other portions that are arranged below the multiple portions, extend in the Y-axis direction, and are arranged at intervals in the X-axis direction.

[0082] Here, in the third embodiment, colored yarns are used for the multiple warp yarns e and f. As a result, in a woven structure 3 manufactured according to a pick diagram (see FIG. 13) described later, as shown in FIG. 12, the multiple warp yarns e and f, which are colored yarns, are exposed at the opening 33, improving the visibility of the opening 33. If the visibility of the opening 33 is improved, when the woven structure 3 is used as, for example, a hanging chain or a work belt, the user of the woven structure 3 can easily recognize where the opening 33 is located, improving the convenience of hanging an object on the opening 33. This effect is more noticeable when the warp yarns e and f are colored yarns dyed with, for example, fluorescent dyes, and the woven structure 3 is used at night.

[0083] [Lower layer] The upper layer 32 has a two-layer structure, and these layers are bound together by multiple warp threads m. The upper layer of the two layers is a plain weave structure of multiple parts of the weft thread B (second weft thread) that extend in the Y-axis direction and are spaced apart in the X-axis direction, and multiple warp threads i and j that extend in the X-axis direction. The lower layer is a plain weave structure of multiple parts of the weft thread B that extend in the Y-axis direction and are spaced apart in the X-axis direction and are continuous with the multiple parts, and multiple warp threads k and l that extend in the X-axis direction (see FIG. 14).

[0084] The multiple warp threads m extend in the X-axis direction and are spaced apart in the Y-axis direction. The multiple warp threads m are binding threads that bind the upper layer and the lower layer of the lower layer 32 by being entangled with multiple portions of the weft thread B that extend in the Y-axis direction and are spaced apart in the X-axis direction, and multiple other portions that are arranged below the multiple portions, extend in the Y-axis direction, and are spaced apart in the X-axis direction.

[0112] (Operation M a~m 9,25,29,33) The loom device 40 operates a~m In 9, the above operation m a~g 9,m i~m 9 and m h 14, the needles of the loom device 40 carry out the wefts A and B in the Y2 direction, passing the weft A below each of the warp threads f and g and above each of the warp threads a to e, h to m, and passing the weft B below each of the warp threads a to i, m and above each of the warp threads j to l. The loom device 40 performs these operations as operation M. a~m The same is true for 25, 29, and 33. a~m 25, M a~m 29, M a~m 33, respectively, a~g 25,m i~m 25 and m h 25, m a~g 29,mi~m 29 and m h 29, m a~g 33,m i~m 33 and m h 33 are carried out in parallel by the weaving device 40.

[0113] In the third embodiment, the number of warp threads i to m corresponding to the lower layer 32 may be greater than the number of warp threads a to g and warp thread h corresponding to the upper layer 31. In this case, in the above step Sc2, the operator of the manufacturing system 100 may set the conveyance amount (e.g., conveyance speed) of the weft thread B per unit time in the Y-axis direction to be greater than the conveyance amount (e.g., conveyance speed) of the weft thread A per unit time in the Y-axis direction, so that the woven structure 3 in which the dimension (width) of the lower layer 32 in the Y-axis direction is greater than the dimension (width) of the upper layer 31 in the Y-axis direction may be manufactured as shown in FIG. 15. In the woven structure 3, as shown in the same figure, the width of the upper layer 31 at the opening 33 of the woven structure 3 is smaller than the width of the lower layer 32. As a result, when the woven structure 3 is used as, for example, a hanging chain or a work belt, it becomes easier to hang an object on the opening 33 compared to when the width of the upper layer 31 is equal to the width of the lower layer 32, and the convenience of the woven structure 3 is improved. In addition, in the woven fabric structure 3, due to the specifications of the weaving machine 40, the side surface of the upper layer 31 located in the Y2 direction and the side surface of the lower layer 32 located in the Y2 direction are flush with each other.

[0114] As described above, the manufacturing method of the woven fabric structure 3 according to the third embodiment includes an upper layer 31 having a weave structure of a weft yarn A extending in the Y-axis direction and having a portion spaced apart in the X-axis direction and a plurality of warp yarns a to g extending in the X-axis direction, a lower layer 32 having a weave structure of a weft yarn B extending in the Y-axis direction and having a portion spaced apart in the X-axis direction and a plurality of warp yarns i to m extending in the X-axis direction, and a lower layer 33 having a weave structure of a weft yarn B extending in the Y-axis direction and having a portion spaced apart in the X-axis direction and a plurality of warp yarns i to m extending in the X-axis direction. A method for manufacturing a woven fabric structure 3 comprising a plurality of warp threads h binding an upper layer 31 and a lower layer 32, and openings 33 separating the upper layer 31 and the lower layer 32 are intermittently provided in the X-axis direction, wherein a step Sc1 of entangling a weft thread A with the plurality of warp threads a-g, a step Sc2 of entangling a weft thread B with the plurality of warp threads i-m, and a step Sc3 of entangling the weft threads A and B with the plurality of warp threads h are executed in parallel by a weaving machine device 40.

[0115] According to the above embodiment, the weaving apparatus 40 executes in parallel the process of creating the upper layer 31 and the lower layer 32 and the process of binding the created upper layer 31 and the lower layer 32. That is, the weaving apparatus 40 binds the upper layer 31 and the lower layer 32 that are in the process of being created while creating the upper layer 31 and the lower layer 32. As a result, when the woven structure 3 is completed through the above steps Sc1 to Sc3, the upper layer 31 and the lower layer 32 are already bound together. Therefore, a separate process of binding the upper layer 31 and the lower layer 32 is not required to obtain the woven structure 3, and the weaving apparatus 40 can manufacture the woven structure 3 at a lower cost and in a shorter time than before.

[0116] <<Fourth embodiment>> Next, a fourth embodiment of the present invention will be described. In the following description of the fourth embodiment, the same reference numerals are used for configurations, steps, functions, etc. similar to those of the first embodiment, and the description thereof may be omitted or simplified.

[0117] <Information processing device> The CPU 101 according to the fourth embodiment executes a program P4 based on a pick diagram (see FIG. 17) described later, which is stored in the ROM 102, the RAM 103, the storage device 110, or the removable recording medium 114, to perform a method for manufacturing a woven structure (step S d 1 to 3) are executed by the weaving device 50 of the fourth embodiment. The program P4 may be a program pre-recorded in the ROM 102, the RAM 103, the storage device 110, or the removable recording medium 114, or may be a program downloaded from a server device such as an external server or a cloud server via the network NW.

[0118] <Loom equipment> The weaving apparatus 50 is a needle loom that manufactures a woven fabric structure by vertically moving each of a plurality of heald frames (not shown) corresponding to each of a plurality of warp threads (a plurality of warp threads a-d, g) and repeating the operation of passing weft threads (weft threads A, B) between the warp threads via needles (cross needles) at high speed in accordance with program control of the information processing apparatus 10 based on the program P4. Specifically, the weaving apparatus 50 is, for example, a two-strand electronic dobby high-speed needle loom (model number: NFRE-42·2 / 84EDZ10S3, manufactured by Jakob Muller AG).

[0119] <Configuration of woven structure> Next, the configuration of the woven fabric structure 4 manufactured by the manufacturing method for a woven fabric structure according to the fourth embodiment will be described.

[0120] Fig. 16 is a perspective view showing a configuration example of the woven structure 4. The woven structure 4 has an upper layer 41 (first layer), a lower layer 42 (second layer), and a plurality of warp threads h (third warp threads). As shown in Fig. 16, the woven structure 4 is provided with a plurality of openings 43. The openings 43 are portions of the woven structure 4 where the upper layer 41 and the lower layer 42 are not bound by the warp threads h and can be separated from each other. As shown in the same figure, the plurality of openings 43 are provided intermittently in the X-axis direction.

[0121] The dimension (width) of the woven fabric structure 4 in the Y-axis direction is not particularly limited, but is preferably, for example, 10 mm or more and 80 mm or less. The thickness of the woven fabric structure 4 is also not particularly limited, but is preferably, for example, 1 mm or more and 7 mm or less. The woven fabric structure 4 is used, for example, as a hanging chain or a work belt, but the uses of the woven fabric structure 4 are not limited thereto.

[0122] [Upper layer] The weft thread A (first weft thread) in the third embodiment has multiple parts a1, a2 extending in the Y-axis direction and spaced apart in the X-axis direction, and multiple parts a3, a4 arranged below the multiple parts a1, a2, extending in the Y-axis direction, and spaced apart in the X-axis direction, and these are connected into a continuous thread. The upper layer 41 has a two-layer structure, and these layers are bound together by a plurality of warp threads g. The upper layer of the two layers is made up of a plain weave structure of a plurality of portions a1 of the weft threads A and a plurality of warp threads a and b, and a plain weave structure of a plurality of portions a2 of the weft threads A and a plurality of warp threads c and d. The lower layer is made up of a plain weave structure of a third plurality of portions a3 of the weft threads A and a plurality of warp threads c and d, and a plain weave structure of a fourth plurality of portions a4 of the weft threads A and a plurality of warp threads a and b (see FIG. 18).

[0123] Here, in the fourth embodiment, colored yarns are used for the multiple warp yarns c and d. As a result, in a woven structure 4 manufactured according to a pick diagram (see FIG. 17) described later, as shown in FIG. 16, the multiple warp yarns c and d, which are colored yarns, are exposed at the opening 43, improving the visibility of the opening 43. If the woven structure 4 is used as, for example, a hanging chain or a work belt, the improved visibility of the opening 43 makes it easier for a user of the woven structure 4 to recognize where the opening 43 is located, improving the convenience of hanging an object on the opening 43. This effect is more noticeable when the warp yarns c and d are colored yarns dyed with, for example, fluorescent dyes, and the woven structure 4 is used at night.

[0124] The multiple warp threads g extend in the X-axis direction and are spaced apart in the Y-axis direction. The multiple warp threads g are binding threads that bind the upper layer and the lower layer of the upper layer 41 by being entangled with the multiple portions a1, a2 and the multiple portions a3, a4.

[0125] [Lower layer] The lower layer 42 has a two-layer structure, and these layers are bound together by multiple warp threads m. The upper layer of the two layers is a plain weave structure of multiple parts of the weft thread B (second weft thread) that extend in the Y-axis direction and are spaced apart in the X-axis direction, and multiple warp threads i and j that extend in the X-axis direction. The lower layer is a plain weave structure of other multiple parts of the weft thread B that extend in the Y-axis direction and are spaced apart in the X-axis direction and are continuous with the multiple parts, and multiple warp threads k and l that extend in the X-axis direction (see FIG. 18).

[0126] The multiple warp threads m extend in the X-axis direction and are arranged at intervals in the Y-axis direction.

That is, the loom apparatus 50 binds the upper layer 41 and the lower layer 42 in the middle of being created while creating the upper layer 41 and the lower layer 42. In this way, the woven fabric structure 4 can be produced in the above step S. d 1~S d At the stage where the weaving machine 50 is completed through step 3, the upper layer 41 and the lower layer 42 are already bound together. Therefore, a separate step of binding the upper layer 41 and the lower layer 42 is not required to obtain the woven fabric structure 4, and the loom apparatus 50 can manufacture the woven fabric structure 4 at lower cost and in a shorter time than in the past.

As shown in Fig. 20, a plurality of openings 53 are provided in the woven fabric structure 5. The openings 53 are portions of the woven fabric structure 5 where the upper layer 11 and the lower layer 12 are separated from each other by not being bound by the warp threads e to h. As shown in the same figure, the plurality of openings 53 are provided intermittently in the X-axis direction.

[0169] The dimension (width) of the woven fabric structure 5 in the Y-axis direction is not particularly limited, but is preferably, for example, 10 mm or more and 80 mm or less. The thickness of the woven fabric structure 5 is also not particularly limited, but is preferably, for example, 1 mm or more and 7 mm or less. The woven fabric structure 5 is used, for example, as a hanging chain or a work belt, but the uses of the woven fabric structure 5 are not limited thereto.

[0170] [Warp threads e~h] The multiple warp threads e-h extend in the X-axis direction and are spaced apart in the Y-axis direction. The warp threads e-h are entangled with the portions A1 and B1 of the weft threads A and B in different ways (see FIG. 22). The multiple warp threads e-h are entangled with the portion A1 of the weft thread A and the portion B1 of the weft thread B to form binding threads that intermittently bind the upper layer 11 and the lower layer 12 together.

[0195] In the fifth embodiment, the number of warp threads c and d corresponding to the lower layer 12 may be greater than the number of warp threads a, c and warp threads e to h corresponding to the upper layer 11. In this case, the loom apparatus 60 performs the above step S e2, for example, the operator of the manufacturing system 100 may set the conveyance amount (e.g., conveyance speed) per unit time of the weft yarn B in the Y-axis direction to be greater than the conveyance amount (e.g., conveyance speed) per unit time of the weft yarn A in the Y-axis direction, thereby manufacturing a woven structure 5 in which the dimension (width) of the lower layer 12 in the Y-axis direction is greater than the dimension (width) of the upper layer 11 in the Y-axis direction, as shown in FIG. 23. In the woven structure 5, as shown in the figure, the width of the upper layer 11 at the opening 53 of the woven structure 5 is smaller than the width of the lower layer 12. As a result, when the woven structure 5 is used as, for example, a hanging chain or a work belt, it becomes easier to hang an object on the opening 53 compared to when the width of the upper layer 11 is equal to the width of the lower layer 12, and the convenience of the woven structure 5 is improved. In addition, in the woven structure 5, the side surface of the upper layer 11 located in the Y2 direction and the side surface of the lower layer 12 located in the Y2 direction are flush with each other due to the specifications of the weaving machine device 60.

[0197] According to the above embodiment, the weaving apparatus 60 executes in parallel the process of creating the upper layer 11 and the lower layer 12, and the process of binding the created upper layer 11 and the lower layer 12. That is, the weaving apparatus 60 binds the upper layer 11 and the lower layer 12 in the middle of being created while creating the upper layer 11 and the lower layer 12. In this way, the woven fabric structure 5 can be produced in the above step S. e 1~S e At the stage where the weaving machine 60 is completed through step 3, the upper layer 11 and the lower layer 12 are already bound together. Therefore, a separate step of binding the upper layer 11 and the lower layer 12 together is not required to obtain the woven structure 5, and the woven structure 5 can be manufactured by the loom apparatus 60 at lower cost and in a shorter time than in the past.

[0198] 2. Supplementary Information The woven structures exemplified in the above embodiments are hanging chains and work belts, but the manufacturing method for a woven structure of the present invention may be a method for manufacturing a woven structure other than a hanging chain or a work belt, and the use of the present invention is not particularly limited.

[0199] Furthermore, the effects described herein are merely descriptive or exemplary and are not limiting, that is, the present invention may have other effects in addition to or in place of the above effects that would be apparent to a person skilled in the art from the description of the present specification.

[0200] Although the preferred embodiment of the present invention has been described in detail above with reference to the accompanying drawings, the technology of the present invention is not limited to the above embodiment. It is clear that a person having ordinary knowledge in the technical field to which the present invention pertains can conceive of various modified or altered examples within the scope of the technical ideas described in the claims, and it is understood that these also naturally belong to the technical scope of the present invention.

[0201] 3. Notes From the above-mentioned exemplary embodiments, the following aspects can be understood, for example.

[0202] A manufacturing method for a woven structure according to one aspect (aspect 1) of the present invention includes a first layer having a weave structure of a first weft yarn extending in a first direction and having portions spaced apart in a second direction perpendicular to the first direction, and a plurality of first warp yarns extending in the second direction, a second layer having a weave structure of a second weft yarn extending in the first direction and having portions spaced apart in the second direction, and a plurality of second warp yarns extending in the second direction, and a plurality of third warp yarns extending in the second direction, the plurality of third warp yarns extending in the second direction and spaced apart in the first direction, binding the first layer and the second layer, and an opening separating the first layer and the second layer is intermittently provided in the second direction, wherein a first step of entangling the first weft yarn with the plurality of first warp yarns, a second step of entangling the second weft yarn with the plurality of second warp yarns, and a third step of entangling the first and second weft yarns with the plurality of third warp yarns are carried out in parallel.

[0203] According to the above aspect, the process of creating the upper layer and the lower layer and the process of binding the created upper layer and the lower layer are carried out in parallel. That is, while the upper layer and the lower layer are being created, the upper layer and the lower layer in the middle of being created are bound together. As a result, when the woven structure is completed through the above-mentioned first to third steps, the upper layer and the lower layer are already bound together. Therefore, a separate process of binding the upper layer and the lower layer is not required to obtain the woven structure, and the woven structure can be manufactured at a lower cost and in a shorter time than before.

[0204] According to a specific example (Aspect 2) of Aspect 1, in the first step, a predetermined first pattern which is the rule for how the first weft thread is entangled with the plurality of first warp threads is repeated, in the second step, a predetermined second pattern which is the rule for how the second weft thread is entangled with the plurality of second warp threads is repeated, and in the third step, a predetermined third pattern which is the rule for how the first and second weft threads are entangled with the plurality of third warp threads is repeated.

[0205] According to a specific example (Aspect 3) of Aspect 2, the first pattern consists of 22 operations of entangling the first weft thread with the multiple first warp threads, the second pattern consists of 22 operations of entangling the second weft thread with the multiple second warp threads, and the third pattern consists of 22 operations of entangling the first and second weft threads with the multiple third warp threads.

[0206] According to a specific example of aspect 2 (aspect 4), the first pattern consists of 40 operations of entangling the first weft thread with the multiple first warp threads, the second pattern consists of 40 operations of entangling the second weft thread with the multiple second warp threads, and the third pattern consists of 40 operations of entangling the first and second weft threads with the multiple third warp threads.

[0207] According to a specific example (Aspect 5) of Aspect 4, the plurality of first warp threads include colored threads exposed at the opening. According to Aspect 5, the plurality of warp threads that are colored threads are exposed at the opening, improving the visibility of the opening. With the improved visibility of the opening, when the textile structure is used, for example, as a hanging chain or a work belt, the user of the textile structure can easily recognize where the opening is located, improving the convenience of hanging items on the opening. This effect is more pronounced when the colored threads are threads dyed with, for example, fluorescent dyes, and the textile structure is used at night.

[0208] According to a specific example (aspect 6) of aspect 4, in the third pattern, the binding strength between the first layer and the second layer is increased stepwise in the second direction, whereby the woven fabric structure has a configuration in which the binding strength between the upper layer and the lower layer is increased stepwise in the second direction.

[0209] According to a specific example (Aspect 7) of any one of Aspects 1 to 5, the dimension of the opening in the second direction is changed by changing the way in which the first and second wefts are entangled with the third warps, whereby the dimension of the opening in the second direction can be set to a desired dimension, and various woven structures having different dimensions can be manufactured.

[0210] According to a specific example (Aspect 8) of any one of Aspects 1 to 6, in the second step, the transport amount per unit time of the second weft in the first direction is greater than the transport amount per unit time of the first weft in the first direction. According to Aspect 8, it is possible to manufacture a woven structure in which the dimension (width) of the lower layer in the first direction is greater than the dimension (width) of the upper layer in the first direction. As a result, in the woven structure, the width of the upper layer at the opening is smaller than the width of the lower layer. When the woven structure is used as, for example, a hanging chain or a work belt, it becomes easier to hang objects on the opening compared to when the width of the upper layer is equal to the width of the lower layer, improving the convenience of the woven structure.

That is, the weaving device binds the upper layer and lower layer in the middle of being created while creating the upper layer and the lower layer.

Therefore, a separate step of binding the upper layer and the lower layer is not required to obtain the woven structure, and the weaving device can manufacture the woven structure at lower cost and in a shorter time than before.
