Comprising a first fabric body and a second fabric body, the first fabric body and the second fabric body are in a mutually sewn state, the first fabric body and the second fabric body are each of a double-face different-pattern structure, namely, a printing A and a printing B, the first fabric body and the second fabric body are each of a multi-layer structure, and traction structures used for tensioning the double-face different-pattern structures are arranged in the first fabric body and the second fabric body. Due to the fact that the first thread guiding needle is alternately knitted with the second thread guiding needle and the third thread guiding needle in the circulation process, the knitting effect of double-face different patterns can be achieved by controlling color distribution of the second batch of warps and the third batch of warps penetrating through the second thread guiding needle and the third thread guiding needle, and the double-face patterns are synchronously knitted; the knitting efficiency is high, and the first thread guide needle, the second thread guide needle and the third thread guide needle alternately knit, so that the overall structural strength of a knitted finished product is greatly improved.

Description

Technical Field

[0001] The invention relates to the technical field of fabric textiles, in particular to a double-sided wide-width jacquard fabric with different patterns and a weaving method thereof. Background Art

[0002] Fabric weaving is the process of converting fibers into fabrics, and jacquard fabric is a fabric with complex patterns and designs. Its characteristic is that the pattern is formed by changing the arrangement of the warp and weft threads in the fabric. This weaving method can create a three-dimensional effect and rich texture effects. Jacquard fabric is often used in clothing, home textiles such as curtains, sofas, bedding, and decorative materials. Double-sided jacquard fabric is a fabric with different patterns or colors, and different patterns or designs are usually visible on both sides of the fabric. Compared with traditional single-sided jacquard fabric, double-sided jacquard fabric has a more complex weaving process and can show unique visual effects and touch on both sides at the same time.

[0003] Patent publication number CN117758418A discloses a double-sided, wide-width jacquard fabric and its weaving method, which elevates the fabric's appearance and quality. This represents a significant breakthrough in new product development, offering new insights into the development of silk double-layer jacquard fabrics. The fabric utilizes the common pattern on both sides A and B as the optimal joining point, connecting the two layers. This improves the fabric's integrity, prevents product slippage, maintains the silk's soft hand, and enhances weaving quality. This innovation also brings individuality and fashion to silk products.

[0004] When the above-mentioned and similar technical solutions are used to weave double-sided heterogeneous jacquard fabrics, since the pattern on one side will have thread end nodes on the other side, the weaving effect of the pattern will be affected when the pattern on the other side is weaved, and the pattern on one side will appear on the other side, affecting the overall appearance. When double-sided heterogeneous weaving is performed, since the warp threads need to be layered and the heterogeneous patterns need to be woven during the weaving process, the structural strength of the woven finished product will be poor and it will be easily damaged. Summary of the Invention

[0005] The object of the present invention is to provide a double-sided wide jacquard fabric with different patterns and a weaving method thereof, so as to solve the problems raised in the above background technology.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] In the first aspect, a double-sided heterogeneous wide-width jacquard fabric and a weaving method thereof are designed, comprising a first fabric and a second fabric, wherein the first fabric and the second fabric are sewn together, and both the first fabric and the second fabric have double-sided heterogeneous structures, namely A print and B print respectively, and both the first fabric and the second fabric have multi-layer structures, and a traction structure for tightening the double-sided heterogeneous structure is provided in the first fabric and the second fabric.

[0008] Furthermore, the first fabric and the second fabric are both double-layer structures, with the A print being in the first layer structure and the B print being in the second layer structure.

[0009] Furthermore, the traction structure is a central traction line, and the central traction line is alternately woven with the first layer structure and the second layer structure.

[0010] A method for weaving a double-sided wide jacquard fabric with different patterns is provided, using the double-sided wide jacquard fabric with different patterns described above. The process comprises:

[0011] S1: Separate preparation, preparing a first fabric and a second fabric respectively by a first preparation method;

[0012] S2: Split splicing: splicing the first fabric and the second fabric based on the splicing method to obtain a finished fabric.

[0013] Furthermore, the first preparation method includes:

[0014] M1: Lead arrangement, with multiple lead pins No. 1, No. 2, and No. 3, with the No. 2 lead pin located between the No. 1 and No. 3 lead pins;

[0015] M2: Warp arrangement, set up multiple batches of warp yarns, and pass through the No. 1 lead needle, No. 2 lead needle and No. 3 lead needle respectively;

[0016] M3: Weft yarn arrangement, with at least two weft yarn ejectors, located between the first and second thread guide needles and between the second and third thread guide needles respectively, and a weft yarn front presser for pressing the weft yarn ejected by the weft yarn ejectors;

[0017] M4: Alternating cycle, the No. 1 lead needle, the No. 2 lead needle and the No. 3 lead needle respectively drive the first batch of warp yarns, the second batch of warp yarns and the third batch of warp yarns to interact alternately with the weft yarn ejector, and the weft yarn front presser presses the weft yarn to obtain the first fabric and the second fabric.

[0018] Furthermore, the weft yarn pressing device is provided with at least two cutting knives for cutting the weft yarn.

[0019] Furthermore, the splicing method includes:

[0020] X1: Edge cutting: cutting the edges of the first fabric and the second fabric to obtain cut fabric A and cut fabric B;

[0021] X2: Fabric merging, based on cut fabric A and cut fabric B, side by side sewing by target machine.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] The double-sided wide-width jacquard fabric with different patterns and the weaving method thereof have the advantages that, since the No. 1 lead needle alternately weaves with the No. 2 lead needle and the No. 3 lead needle during a circulation process, a double-sided different-pattern weaving effect can be achieved by controlling the color distribution of the second batch of warp threads and the third batch of warp threads passing through the No. 2 lead needle and the No. 3 lead needle, and the double-sided patterns are woven synchronously, so the weaving efficiency is high. Moreover, the No. 1 lead needle alternately weaves with the No. 2 lead needle and the No. 3 lead needle, thereby greatly improving the overall structural strength of the finished product.

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] A double-sided, heterogeneous wide jacquard fabric includes a first fabric 101 and a second fabric 201. The first fabric 101 and the second fabric 201 are sewn together. The first fabric 101 and the second fabric 201 both have double-sided, heterogeneous structures, with A print and B print respectively. The first fabric 101 and the second fabric 201 both have multi-layer structures. A traction structure for tightening the double-sided, heterogeneous structures is provided in the first fabric 101 and the second fabric 201.

[0030] The first fabric 101 and the second fabric 201 are both double-layer structures, with the A print being in the first layer and the B print being in the second layer.

[0031] The traction structure is a central traction line, which is alternately woven with the first layer structure and the second layer structure.

[0032] A method for weaving a double-sided wide-width jacquard fabric with different patterns uses the above-mentioned double-sided wide-width jacquard fabric. The process includes: S1: separate preparation, in which a first fabric 101 and a second fabric 201 are prepared separately by a first preparation method; S2: separate splicing, in which the first fabric 101 and the second fabric 201 are spliced ​​based on the splicing method to obtain a finished fabric.

[0033] like Figure 2-3 As shown, the first preparation method includes: M1: thread arrangement, multiple thread guide needles No. 1, No. 2 and No. 3 are set, and the No. 2 thread guide needle is located between the No. 1 and No. 3 thread guide needles; M2: warp arrangement, multiple batches of warp yarns are set, which pass through the No. 1 thread guide needle, No. 2 and No. 3 thread guide needles respectively; M3: weft arrangement, at least two weft jets are set, which are respectively located between the No. 1 thread guide needle and the No. 2 thread guide needle and the No. 3 thread guide needle, and a weft presser is set to press the weft yarns ejected by the weft jet; M4: cyclic alternation, the No. 1 thread guide needle, the No. 2 thread guide needle and the No. 3 thread guide needle respectively drive the first batch of warp yarns, the second batch of warp yarns and the third batch of warp yarns to interact alternately with the weft jets, and the weft presser presses the weft yarns to obtain the first fabric 101 and the second fabric 201.

[0034] It should be noted that since the No. 2 lead needle is located between the No. 1 lead needle and the No. 3 lead needle, and the three batches of warp yarns are passed through the No. 1 lead needle, the No. 2 lead needle and the No. 3 lead needle respectively, the No. 1 lead needle, the No. 2 lead needle and the No. 3 lead needle are staggered. When the No. 1 lead needle and the No. 2 lead needle alternate up and down, one of the weft yarn injectors sprays water, and uses the water flow to spray the weft yarn at the same time, and passes through the first batch of warp yarns and the second batch of warp yarns driven by the No. 1 lead needle and the No. 2 lead needle. At this time, the weft yarn presser presses the weft yarn, and the No. 1 lead needle and the No. 2 lead needle alternate again, and the weft yarn injector sprays water again, and uses the water flow to spray the weft yarn at the same time, and passes through the first batch of warp yarns and the second batch of warp yarns driven by the No. 1 lead needle and the No. 2 lead needle again. Yarn, at this point, lead needle No. 1 is reset, and lead needle No. 1 and lead needle No. 3 alternate up and down, another weft yarn ejector sprays the weft yarn, passes through the first batch of warp yarns and the third batch of warp yarns driven by lead needle No. 1 and lead needle No. 3, the weft yarn front presser presses the weft yarn again, repeats the steps, lead needle No. 1 is reset again, and a weaving cycle is completed. Since lead needle No. 1 weaves alternately with lead needle No. 2 and lead needle No. 3 during the cycle, the double-sided different flower weaving effect can be completed by controlling the color distribution of the second batch of warp yarns and the third batch of warp yarns passing through lead needle No. 2 and lead needle No. 3, and the structural strength of the overall woven product is greatly improved.

[0035] The weft yarn front presser is provided with at least two cutting knives for cutting the weft yarn.

[0036] The splicing method includes: X1: edge cutting, cutting the edges of the first fabric 101 and the second fabric 201 to obtain cut fabric A and cut fabric B; X2: fabric merging, based on the cut fabric A and the cut fabric B, side by side sewing through the target device.

[0037] It should be noted that the target device is a sewing machine. When wider fabric is needed, multiple cut fabrics A and B are sewn together to achieve the weaving effect of wide jacquard fabrics.

[0038] In order to verify the improvement of the structural strength of the fabric obtained in this application compared to conventional fabrics, the finished fabric obtained in the embodiment and the conventional fabric were tested for tensile strength. This test was carried out using a tensile testing machine. Three samples were taken from the cut fabric A and cut fabric B obtained in this application, respectively, and recorded as A1, A2, A3, B1, B2, B3. The side length of the sample was 150 mm and the thickness was 5 mm. Three samples were taken from conventional fabrics, respectively, and recorded as C1, C2, C3. The side length of the sample was 150 mm and the thickness was 5 mm. The sample was fixed on the tensile testing machine to ensure that the sample would not slide during the stretching process. The test was started and the maximum force required for uniform stretching to break was measured. The test results are shown in Table 1. Due to equipment and operating errors, there are slight differences in the impact resistance results of the same material. This is within the normal range. During the test, it is necessary to strictly abide by the use specifications of the equipment to reduce the error. The specific test steps will vary depending on the equipment, so they are not described in detail.

[0039] Table 1

[0040] Sample name A1 A2 A3 B1 B2 B3 C1 C2 C3 Breaking load / N 419 421 420 411 412 425 270 275 279 Tensile length / mm 5 3 4 4 5 4 11 12 12

[0041] It can be seen from Table 1 that after three samples of the cut fabric A and the cut fabric B obtained in the present application were tested on a tensile testing machine, the breaking load was maintained above 400N, and the tensile length was below 5mm. The breaking load of the three samples of conventional fabrics obtained was below 300N, and the tensile length was above 12mm. The experiment shows that the technical solution provided by the present application has a certain improvement in structural strength.

[0042] In the same way, three samples were taken from the cut fabric A and cut fabric B obtained in the present application, and they were recorded as A4, A5, A6, B4, B5, and B6 respectively. The side length of the samples was 150 mm and the thickness was 5 mm. Three samples were taken from conventional fabrics and they were recorded as C4, C5, and C6 respectively. The side length of the samples was 150 mm and the thickness was 5 mm. The samples were fixed on a wear-resistant testing machine and the wear test was started. The wear material selected was nylon abrasive, and the number of wears was set to 500 (± 5) times. The test results are shown in Table 2. Due to equipment and operation errors, there are slight differences in the impact resistance results of the same material, which is within the normal range. During the test, it is necessary to strictly abide by the equipment usage specifications to reduce the error. The specific test steps will vary depending on the equipment, so they are not described in detail.

[0046] It can be seen from Table 2 that after three samples of the cut fabric A and the cut fabric B obtained in this application were tested on a wear resistance testing machine, the wear area was basically maintained at 2-3 mm2, while the wear area of ​​the three samples of conventional fabrics obtained was basically maintained at 7-8 mm2. The experiment shows that the technical solution provided by this application has a certain improvement in structural strength.
