Description

Technical Field

[0001] This application relates to a processing method for a multi-color weft jacquard bag fabric, belonging to the technical field of textured woven fabrics with special purposes. Background Technology

[0002] In bag fabric processing, due to established practices, two- or four-color fabrics are commonly used, with fewer than four colors. While this doesn't affect the daily use of bags, it's clearly detrimental to product diversity and personalization. In today's market, besides storage, bags are increasingly being used for decoration and furnishing in home goods. However, current bag processing primarily focuses on two-color (two-pack) and four-color (four-pack) products, with few bags featuring more than four colors. Furthermore, the weft insertion points in weaving are generally of a standard design, requiring high specifications when inputting weft yarns. Conventional weft insertion methods cannot meet the demands of processing multiple colors.

[0003] How to better adapt to this development trend and realize the processing of multi-color bag fabrics in weaving is an urgent problem to be solved in this field. Summary of the Invention

[0004] In view of this, this application provides a processing method for multi-color weft jacquard bag fabric. By setting the weaving structure and weaving method, not only can the finished jacquard fabric be given the wear resistance of bags, but also the product can be given a multi-color (four or more colors) jacquard effect.

[0005] Specifically, this application is implemented through the following scheme:

[0006] A processing method for a multi-color weft jacquard bag fabric involves four main components: reed, weft insertion device, arrow box, and hook.

[0007] The weft insertion device includes, in sequence, a weft feeder, an electronic weft detector, a stranding device, a weft selector, and a cutting mechanism. There are twelve sets of weft feeders. The electronic weft detector, stranding device, and weft selector are all equipped with thread-passing holes, the number of which corresponds to the number of weft feeders. The cutting mechanism includes upper and lower shear blades, which are connected to a motor via a transmission arm. The motor controls their lifting and oscillation.

[0008] The arrow box is correspondingly arranged with the shearing mechanism. An arrowhead is installed in the arrow box. An arc-shaped pressure plate is provided on the side of the arrowhead near the shearing mechanism. The pressure plate and the bottom plate of the arrow box form a groove with decreasing spacing.

[0009] The weft yarn, fed into the weft selector, is fed to the lower shear blade. Driven by a motor and a transmission arm, the lower shear blade moves downward and presses the yarn together. The remaining portion of the weft yarn is then pulled along by the arrow box for a set time. Driven by a motor and a transmission arm, the upper shear blade cuts the yarn, completing the convergent weft selection. The set time is determined by the time it takes for the yarn to reach the center length of the weft weft at the point where it meets the slot.

[0010] The weft yarn at the arrow box is connected to the other end by a hook corresponding to the arrow box, while the warp yarn on the warp beam is pulled to the weft end by the reed. The warp and weft yarns interweave to form the fabric, and the take-up mechanism moves the fabric away from the weft end.

[0011] In the minimum cycle of the fabric structure:

[0012] There are a total of 12 weft yarns, divided into four groups: the first weft, the second weft, the third weft, and the fourth weft.

[0013] The starting warp is formed by using 32 bundles of warp yarns as the starting warp yarns, and four sets of weft yarns interweave with the starting warp yarns to form the starting warp structure;

[0014] Using 40 bundles of warp yarns as the starting warp yarns, four sets of weft yarns are interwoven with the starting warp yarns to form a starting weft structure;

[0015] The warp and weft threads have twelve colors.

[0016] The bag fabric produced by the above process, through the convergent weft selection of the weft insertion device, allows for different cutting times for yarns of different thicknesses. Without changing the existing weft feed distance (to the center of the weft weft), the arc-shaped pressure plate and the bottom plate form progressively narrowing slots. Yarns of different specifications are secured at different positions in these slots, thereby controlling the cutting time of the upper scissor blade. This solves the problem of the universal weft insertion arrow box and arrowheads only allowing for a single weft yarn specification, making it possible to introduce weft yarns of different colors. The resulting fabric's minimum repeat structure includes a 32×12 warp-starting structure and a 40×12 weft-starting structure. Through the combination of weft and warp materials, not only is a jacquard structure formed, but the interweaving of the weft yarn with the weft-starting warp and warp-starting weft yarns enables the weaving of a super-multi-color bag fabric with twelve colors, effectively broadening the application range of bag fabrics.

[0017] Furthermore, as a preferred option:

[0018] In the weft yarns that make up the warp, twelve bundles of weft yarns are arranged in sequence. The first bundle is the first weft, the second bundle is the second weft, the third, fourth, fifth, and sixth bundles are the third weft, and the seventh, eighth, ninth, tenth, eleventh, and twelfth bundles are the fourth weft.

[0019] In the interlacing structure of the starting warp, the position of the first weft relative to the starting warp yarn is: 1 up 1 down 15 up 1 down 14 down; the position of the second weft relative to the starting warp yarn is: 6 down 1 up 5 down 1 up 1 down 1 up 7 down 1 up 5 down 1 up 1 down 1 up 1 up 1 down; the position of the third weft relative to the starting warp yarn is: 14 down 1 up 15 down 1 up 1 down; and the position of the fourth weft relative to the starting warp yarn is: 14 down 1 up 17 down.

[0020] In the weft yarns that make up the weft structure, twelve weft yarns are arranged in sequence. The third yarn is the first weft, the first and second yarns are the second weft, the fourth and fifth yarns are the third weft, and the sixth, seventh, eighth, ninth, tenth, eleventh and twelfth yarns are the fourth weft.

[0021] In the interlacing structure of the weft-starting weft weave, the first weft is above the forty bundles of weft-starting warp yarns. The position of the second weft relative to the weft-starting warp yarns is: 19-1 ...

[0022] The aforementioned weft yarn and the starting warp yarn form a single-structure starting weft weft weft structure.

[0023] In the weft yarns that make up the weft structure, twelve weft yarns are arranged in sequence. The first and third bundles are the first weft, the second bundle is the second weft, the fourth and fifth bundles are the third weft, and the sixth, seventh, eighth, ninth, tenth, eleventh and twelfth bundles are the fourth weft.

[0024] In the interlacing structure of the weft-starting weft weave, the position of the first weft relative to the starting weft warp is: 2 up 1 down 9 up 1 down 9 up 1 down 9 up 1 down 7 up; the position of the second weft relative to the starting weft warp is: 19 down 1 up 19 down 1 up; the position of the third weft relative to the starting weft warp is: 39 down 1 up; the position of the fourth weft relative to the starting weft warp is: 9 down 1 up 30 down.

[0025] The aforementioned weft yarn and the starting warp yarn form a double-structure starting weft weft weft structure.

[0026] In the above scheme, a ball is provided at the top of the pressure plate to prevent the high-speed running yarn from jumping off.

[0027] The lower end of the pressure plate, the arrowhead, and the arrow box are fixed by bolts. When the specifications exceed the suitable range of the slot, the pressure plate can be replaced.

[0028] The jacquard bag fabric formed by the above scheme, through the formation of the weaving structure, gives the jacquard fabric a super multi-color structure of twelve colors, which not only improves the practical value of the fabric, but also allows the fabric to be used directly as a finished product after weaving, without the need for post-processing such as dyeing, printing, and inlaying to meet its diverse decorative needs.

[0038] This embodiment describes a processing method for multi-color weft jacquard bag fabric, which involves four main components: reed, weft insertion device 8, arrow box, and hook.

[0039] Combination Figure 4The weft insertion device 8 includes a weft feeder 81, an electronic weft detector 82, a splitter 83, a weft selector 84, and a cutting mechanism 85 arranged sequentially. There are twelve sets of weft feeders 81. The electronic weft detector 82, the splitter 83, and the weft selector 84 are all provided with thread guide holes (not shown in the figure, conventional round holes). The number of thread guide holes on each component corresponds to the number of weft feeders 81. The cutting mechanism 85 includes an upper shear blade 851 and a lower shear blade 852. The upper shear blade 851 and the lower shear blade 852 are respectively connected to a motor 853 through a transmission arm (not shown in the figure). The motor 853 controls their vertical lifting and horizontal swinging, respectively. For example, the motor 853 drives both blades to swing to a suitable position according to the received signal. Then, the lower shear blade 852 remains stationary and presses down the live end of the weft yarn, while the upper shear blade 851 is driven by the motor 853 to move relative to the lower shear blade 852 to complete the cutting action.

[0040] Arrow box 9 is correspondingly set with shearing mechanism 85, and arrowhead 91 is installed in arrow box 9. Figure 5 An arc-shaped pressure plate 911 is provided on the side of arrow 91 near the shearing mechanism 85. The pressure plate 911 and the bottom plate 92 of arrow box 9 form a slot with decreasing spacing.

[0041] Weft yarns of different diameters (e.g.) Figure 6 The clamping positions of yarns A, B, C, etc., in the weft slots differ, therefore, the actual feed time required for different specifications of weft yarns varies. The set feed time is determined by pre-experimentation to determine the time it takes for the yarn to reach the center of the weft in the slot. Before starting the equipment, parameters such as the diameter of each weft yarn required for weaving are input into the control system. The control system outputs the set feed time based on these parameters, determining the start-up time of the upper and lower blades in the cutting mechanism 85. In this way, even when using a mixture of ultra-fine and extra-coarse weft yarns, optimal weft yarn resolution can be ensured.

[0042] Each weft yarn is fed in by a different weft feeder 81, and then passes through the thread pass holes of the stop bar 821, the electronic weft detector 82, and the splitter 83 to the thread pass hole of the weft selector 84. The live end of the weft yarn fed into the weft selector 84 is sent to the lower shear blade 852. The lower shear blade 852 moves down and presses down under the drive of the motor 853 and the transmission arm. The arrow box 9 passes between the pressed weft yarn and the thread pass hole of the weft selector 84. The weft yarn on the weft feeder 81 is kept output under the traction of the arrow box 9 until the arrow box 9 runs for a set time. The upper shear blade 851 is displaced relative to the lower shear blade 852 under the drive of the motor 853 and the transmission arm to cut the yarn, completing the convergent weft selection. The weft yarn at the arrow box 9 is connected to the other end by the hook corresponding to the arrow box 9, and interweaves with the warp yarn extracted by the reed to the weft opening to form the fabric. Then the take-up mechanism moves the fabric away from the weft opening.

[0043] In the above scheme, components such as the reed, arrow box, weft feeder, electronic weft detector (which detects whether there is any danger passing by and transmits the detected danger signal to the overall system for display; if there is none, it will automatically stop), splitter (to prevent the yarn from getting tangled together), and weft selector are all conventional structures and will not be described in detail.

[0044] The fabric weave formed by the above processing method includes twelve weft yarns, thirty-two warp yarns, and forty weft yarns:

[0045] The twelve weft yarns are divided into four groups: weft 1, weft 2, weft 3, and weft 4.

[0046] During the formation of the warp structure, twelve weft yarns are arranged sequentially. The first yarn is the first weft 1, the second yarn is the second weft 2, the third, fourth, fifth, and sixth yarns are the third weft 3, and the seventh, eighth, ninth, tenth, eleventh, and twelfth yarns are the fourth weft 4.

[0047] Combination Figure 1 During the interlacing process of the first weft 1, the second weft 2, the third weft 3, the fourth weft 4 and the starting warp 5:

[0048] The first weft 1 interweaves with the starting warp yarn 5 in a 1-up-1-down, 15-up-1-down, 14-down pattern. That is, after the first weft yarn enters above the first starting warp yarn, it first passes below the second starting warp yarn, i.e., starting warp yarn 1 51, then goes up to above the third starting warp yarn, up to above the seventeenth starting warp yarn, then goes down to below the eighteenth starting warp yarn, i.e., starting warp yarn 5 55, and then goes up to above the nineteenth starting warp yarn, up to above the thirty-second starting warp yarn, thus completing the interweaving of the first weft 1 and the starting warp yarn 5 in the minimum cycle.

[0049] The second weft 2 interweaves with the starting warp yarn 5 in a pattern of six-down-up-five-down-up-down-one-up-seven-down-up-five-down-up-down-one-up-down. Specifically, one bundle of yarn from the second weft 2 enters above the first starting warp yarn, continues below the sixth starting warp yarn, then ascends to the seventh starting warp yarn (starting warp yarn 2, 52), descends below the eighth starting warp yarn, continues to the twelfth starting warp yarn, ascends above the thirteenth starting warp yarn (starting warp yarn 3, 53), descends below the fourteenth starting warp yarn, and ascends to the fifteenth starting warp yarn (starting warp yarn 4, 5). Above 4, then descend to the sixteenth starting warp yarn, until below the twenty-second starting warp yarn, then ascend to the twenty-third starting warp yarn (starting warp yarn 6, 55), then descend to the twenty-fourth starting warp yarn, until below the twenty-eighth starting warp yarn, then ascend to the twenty-ninth starting warp yarn (starting warp yarn 7, 57), then descend to the thirtieth starting warp yarn, then ascend to the thirty-first starting warp yarn (starting warp yarn 8, 58), then descend to the thirty-second starting warp yarn, completing the interlacing of the second weft 2 and the starting warp yarn 5 in the smallest cycle.

[0050] The third weft 3 interweaves with the starting warp yarn 5 in a pattern of 14-1-15-1-15-15-15-15-15-15. That is, after the four bundles of yarns of the third weft 3 enter below the first starting warp yarn, they go up to the 14th starting warp yarn, then go down to the 15th starting warp yarn (starting warp yarn 4, 54), then go down to the 16th starting warp yarn, then go up to the 30th starting warp yarn, then go up to the 31st starting warp yarn (starting warp yarn 8, 58), then go down to the 32nd starting warp yarn, thus completing the interweaving of the third weft 3 and the starting warp yarn 5 in the smallest cycle.

[0051] The fourth weft 4 interweaves with the starting warp yarn 5 in a 14-down-17-down pattern. That is, after the six bundles of yarns of the fourth weft 4 enter below the first starting warp yarn, they go up to the 14th starting warp yarn, then go down to the 15th starting warp yarn (starting warp yarn 454), and then go down to the 16th starting warp yarn, until the 32nd starting warp yarn, thus completing the interweaving of the fourth weft 4 and the starting warp yarn 5 in the smallest cycle.

[0052] During the formation of the weft structure, twelve weft yarns are arranged sequentially. The third yarn is the first weft 1, the first and second yarns are the second weft 2, the fourth and fifth yarns are the third weft 3, and the sixth, seventh, eighth, ninth, tenth, eleventh and twelfth yarns are the fourth weft 4.

[0053] Combination Figure 2 During the interlacing process of the first weft 1, the second weft 2, the third weft 3, the fourth weft 4 and the first warp 6:

[0054] The first weft 1 interweaves with the first warp 6 in such a way that the third weft yarn, as the first weft 1, skips the first and second weft yarns and goes directly up to the top of the first warp 6, completing the interweaving of the first weft 1 and the first warp 6 in the minimum cycle.

[0055] The second weft 2 interweaves with the first warp 6 in a nineteen-down-nineteen-down-nineteen-down-nineteen pattern. That is, the first and second weft yarns, as the second weft 2, pass under the first warp yarn until the nineteenth warp yarn, then go up to the twentieth warp yarn, which is above the first warp yarn 2 62, then go down to the underside of the twenty-first warp yarn, until the underside of the thirty-ninth warp yarn, then go up to the fortieth warp yarn, which is above the first warp yarn 3 63, thus completing the interweaving of the second weft 2 and the first warp 6 in the smallest cycle.

[0056] The third weft 3 interweaves with the first warp 6 in a 39-down-up manner. That is, the fourth and fifth weft yarns, as the third weft 3, pass under the first warp yarn until the 39th warp yarn, and then go up to the 40th warp yarn, which is above the first warp yarn 63, to complete the interweaving of the third weft 3 and the first warp yarn 6 in the minimum cycle.

[0057] The fourth weft 4 interweaves with the first warp 6 in a nine-up-thirty-down pattern. That is, the remaining weft yarns, as the fourth weft 4, pass under the first warp yarn until they reach the ninth warp yarn, then go up to the tenth warp yarn, which is above the first warp yarn 61, and then go down to the eleventh warp yarn until the fortieth warp yarn, thus completing the interweaving of the fourth weft 4 and the first warp yarn 6 in the minimum cycle.

[0058] The aforementioned thirty-two warp yarns are the starting warp yarns, the forty warp yarns are the starting weft yarns, and the twelve weft yarns are grouped together and interwoven with the starting warp and starting weft yarns to form a single structure in the bag fabric of this case (see Figure 7 Its minimum cycle structure includes a 32×12 warp-starting structure and a 40×12 weft-starting structure. With the help of the combination of weft yarn and warp yarn, not only is the jacquard structure formed, but also the weaving of multi-color bag fabrics with four or more colors is achieved through the interlacing of weft yarn with weft-starting warp yarn and weft-starting warp yarn, effectively expanding the application range of bag fabrics. Example 2

[0059] This embodiment has the same setup as Embodiment 1, except that: during the forming process of the weft-starting structure, the twelve weft yarns are arranged in sequence, the first and third yarns are the first weft 1, the second yarn is the second weft 2, the fourth and fifth yarns are the third weft 3, and the sixth, seventh, eighth, ninth, tenth, eleventh and twelfth yarns are the fourth weft 4.

[0060] Combination Figure 3 During the interlacing process of the first weft 1, the second weft 2, the third weft 3, the fourth weft 4, and the second warp 7:

[0061] The first weft 1 interweaves with the second warp 7 in a pattern of 2 up 1 down 9 up 1 down 9 up 1 down 9 up 1 down 7 up. That is, the first weft yarn and the third weft yarn, which skips the second weft yarn, move as the first weft 1 above the first and second warp yarns, then down to the third warp yarn, i.e., below the second warp yarn 1 71, then up to the fourth to twelfth warp yarns, then down to the thirteenth warp yarn, i.e. below the second warp yarn 3 73, then up to the fourteenth to twenty-second warp yarns, then down to the twenty-third warp yarn, i.e. below the second warp yarn 5 75, then up to the twenty-fourth to thirty-second warp yarns, then down to the thirty-third warp yarn, i.e. below the second warp yarn 6 76, then up to the thirty-fourth to fortieth warp yarns, completing the interweaving of the first weft 1 and the second warp 7 in the smallest cycle.

[0062] The second weft 2 interweaves with the second warp 7 in a nineteen-down-up-nineteen-down-up pattern. That is, the second weft yarn, as the second weft 2, goes down below the first to nineteenth warp yarns, then goes up to the twentieth warp yarn, i.e., the fourth warp yarn 2 74, then goes down below the twenty-first to thirty-ninth warp yarns, then goes up to the fortieth warp yarn, i.e., the second warp yarn 7 77, and then goes down, completing the interweaving of the second weft 2 and the second warp 7 in the minimum cycle.

[0063] The third weft 3 interweaves with the second warp 7 in a 39-down-up manner. That is, the fourth and fifth weft yarns, as the third weft 3, go down below the first to thirty-ninth warp yarns, then go up to the fortieth warp yarn, which is above the second warp 77, and then go down to complete the interweaving of the third weft 3 and the second warp 7 in the minimum cycle.

[0064] The fourth weft 4 interweaves with the second warp 7 in a nine-down-thirty-down pattern. That is, the remaining weft yarns, as the fourth weft 4, go down below the first to ninth bundles of warp yarns, then go up to the tenth bundle of warp yarns, which is above the second warp yarn 72, and then go down below the eleventh to fortieth bundles of warp yarns, completing the interweaving of the fourth weft 4 and the second warp 7 in the smallest cycle.

[0065] The above process creates a double-layered weft structure, enabling bag fabrics with more complex patterns (see...). Figure 7 ). Example 3

[0066] This embodiment has the same setup as Embodiment 1, the difference being: [combination of...] Figure 5 and Figure 6 The bottom of the pressure plate 911 is fixed to the arrow 91 and the arrow box 9 by bolts 912. When the specifications exceed the appropriate range of the slot, the pressure plate can be replaced. The top of the pressure plate 911 is provided with a ball 913 to prevent the yarn from jumping off at high speed.

[0067] The jacquard bag fabric formed by the above scheme, through the formation of the weaving structure, gives the jacquard fabric a super multi-color structure of twelve colors, which not only improves the practical value of the fabric, but also allows the fabric to be used directly as a finished product after weaving, without the need for post-processing such as dyeing, printing, and inlaying to meet its diverse decorative needs.

Thirty-two bundles of warp yarns are used as the starting warp yarns, and four sets of weft yarns are interwoven with the starting warp yarns to form the starting warp structure; Forty bundles of warp yarns are used as the starting warp yarns, and four sets of weft yarns are interwoven with the starting warp yarns to form a starting weft structure; There are twelve colors in both warp and weft weaves. In the aforementioned warp-starting structure, among the twelve sequentially arranged weft yarns, the first yarn is the first weft, the second yarn is the second weft, the third, fourth, fifth, and sixth yarns are the third weft, and the seventh, eighth, ninth, tenth, eleventh, and twelfth yarns are the fourth weft. The position of the first weft relative to the warp-starting yarn is: 1 up 1 down 15 up 14 down. The position of the second weft relative to the warp-starting yarn is: 6 down 1 up 5 down 1 up 1 down 1 up 7 down 1 up 5 down 1 up 1 down 1 up 1 up 1 down 1 up 1 down. The position of the third weft relative to the warp-starting yarn is: 14 down 1 up 15 down 1 up 1 down. The position of the fourth weft relative to the warp-starting yarn is: 14 down 1 up 17 down. In the aforementioned weft-starting structure, among the twelve weft yarns arranged sequentially, the first and third bundles are the first weft, the second bundle is the second weft, the fourth and fifth bundles are the third weft, and the sixth, seventh, eighth, ninth, tenth, eleventh, and twelfth bundles are the fourth weft. The position of the first weft relative to the starting warp yarn is: 2 up 1 down 9 up 1 down 9 up 1 down 9 up 1 down 7 up. The position of the second weft relative to the starting warp yarn is: 19 down 1 up 19 down 1 up. The position of the third weft relative to the starting warp yarn is: 39 down 1 up. The position of the fourth weft relative to the starting warp yarn is: 9 down 1 up 30 down.
