[0008] Warp yarns are disposed between the attachment layer and the decorative layer, with several warp yarns arranged in parallel between the layers, and the direction of the warp yarns is perpendicular to the first weft yarn;

[0009] The warp yarns are joined and alternately wound around the first and second weft yarns, with the joining warp yarns wrapping around the first and second weft yarns at an angle of 360°.

[0010] The first weft yarn is a decorative yarn with decorative patterns; the second weft yarn is a magnetic yarn; the three-dimensional woven fabric is used in conjunction with the attached fabric, and the attached fabric is provided with paramagnetic metal yarn.

[0011] Optionally, a plurality of support layers are arranged between the attachment layer and the decorative layer. The support layer includes a plurality of third weft yarns arranged side by side, with each third weft yarn corresponding to a first weft yarn. Warp yarns are arranged between adjacent decorative layers and support layers, between adjacent support layers, and between adjacent support layers and attachment layers. The connecting warp yarns are wound on the third weft yarns.

[0012] Optionally, the angle of the knotted warp yarn around the third weft yarn is ≥180°.

[0013] Optionally, the splicing warp yarns are arranged correspondingly to the warp yarns, and adjacent splicing warp yarns along the warp direction are located on both sides of the same warp.

[0015] Optionally, the third weft yarn is a high-strength yarn.

[0016] Optionally, the support layer between the attachment layer and the decorative layer is a single layer, and the wrapping angle of the connecting warp yarn around the third weft yarn is 270°.

[0017] Optionally, the density of the first weft yarn in a single layer is 2-4 yarns / cm, and the density of the warp yarn is 4-6 yarns / cm.

[0018] Secondly, this application also provides an external weft insertion component, including a housing, the housing including a left housing and a right housing, a winding shaft formed between the left housing and the right housing, the left housing and the right housing being openable and closable to allow the yarn on the winding shaft to be released from the housing, a hollow inner cavity is provided on the housing, the hollow inner cavity is disposed inside the winding shaft, and a notch is provided on the housing, the notch connecting the outer surface of the housing and the hollow inner cavity.

[0019] Thirdly, the present invention also provides a method for preparing the single-sided magnetic three-dimensional woven fabric described in the first aspect based on the external weft insertion component described in the second aspect, comprising the following steps:

[0020] S1: The warp yarns travel in the weaving direction through the gaps between the reeds;

[0021] S2: The warp yarn is inserted into the reed teeth in the steel reed and moves up and down under the action of the reed teeth. In one longitudinal unit movement, the warp yarn moves to below the warp yarn under the action of the reed teeth, and the third weft yarn enters between the two adjacent warp yarns above the warp yarn under the guidance of the shuttle.

[0022] S3: The hook needle on the external weft guide component moves to drive the connecting warp yarn to wrap around the outer circumference of the winding shaft of the external weft guide component once. Then, the second weft yarn is guided to pass through the hollow inner cavity of the external weft guide component. Subsequently, the left and right shells of the external weft guide component open and move away from the connecting warp yarn, causing the connecting warp yarn to come out of the external weft guide component. At the same time, the second weft yarn comes out from the notch on the external weft guide component and moves away from the external weft guide component, thus the connecting warp yarn wraps around the second weft yarn once, completing the wrapping on the second weft yarn.

[0023] S4: Then, the connecting warp yarn moves upward under the action of the reed teeth, passing around the third weft yarn in sequence to the upper external weft guide component. The connecting warp yarn wraps around the outer periphery of the upper external weft guide component once, and then guides the first weft yarn through the hollow inner cavity of the external weft guide component. Subsequently, the external weft guide component opens and separates from the connecting warp yarn. The connecting warp yarn comes out of the external weft guide component, and at the same time, the first weft yarn comes out from the notch on the external weft guide component. Thus, the connecting warp yarn wraps around the first weft yarn once, completing the wrapping on the first weft yarn.

[0024] S5: Then the warp yarns are driven by the reed to enter the next longitudinal unit, and the above operation is repeated until a single-sided magnetic three-dimensional fabric is woven.

[0028] The fabric of this invention is woven from specific yarns. Utilizing the electromagnetic effect of external weft insertion components, the magnetic warp yarns can be repeatedly wound around the weft yarns, tightly and firmly bonding the three-layer structure together. This not only enhances the fabric's structural stability but also effectively maintains its three-dimensionality and shape. The fabric can be freely attached and moved onto special fabric surfaces without additional adhesives or parts, making installation and disassembly convenient. It is suitable for various fields such as tourism and cultural creative products, fashion accessories, and home decoration, offering both flexibility and functionality. Attached Figure Description

[0043] Example 1

[0044] A single-sided magnetic three-dimensional woven fabric includes three layers: a decorative layer, a support layer, and an attachment layer. The decorative layer consists of several parallel first weft yarns y1, the support layer consists of several parallel third weft yarns y3, and the attachment layer consists of several parallel second weft yarns y2. The first weft yarns y1, second weft yarns y2, and third weft yarns y3 are arranged in the same direction and correspond one-to-one. Between adjacent layers (between the decorative layer and the support layer; between the support layer and the attachment layer), several parallel warp yarns x are arranged, with the direction of the warp yarns x perpendicular to the first weft yarns y1. A connecting warp yarn z is wound around the first weft yarns y1, third weft yarns y3, and second weft yarns y2. The connecting warp yarn z does not pass through the upper weft guide component 2 during the winding process. The winding method of the connecting warp yarn z is as follows: Figure 1As shown, the densities of the single-layer warp yarn x, the first weft yarn y1, and the bonding warp yarn z are 5, 3, and 6 yarns / cm, respectively. The first weft yarn y1 is a decorative yarn, the warp yarn x and the third weft yarn y3 are high-strength yarns, and the second weft yarn y2 and the bonding warp yarn z are magnetic yarns. The three-dimensional woven fabric is used in conjunction with an attached fabric, which has paramagnetic metal yarns on it.

[0045] In existing technologies, the winding method of warp yarns onto weft yarns in three-dimensional structures is always half-turn winding, resulting in poor overall structural reliability and mechanical properties. To achieve full-circle winding of the weft yarns, this application provides an additional weft guide component 2, such as... Figure 3 As shown, the device includes a housing, comprising a left housing 21 and a right housing 22, with a winding shaft 23 formed between the left housing 21 and the right housing 22. The left housing 21 and the right housing 22 are openable and closable to allow the yarn on the winding shaft 23 to detach from the housing. A hollow inner cavity 24 is provided on the housing and disposed inside the winding shaft 23. A notch 25 is provided on the housing, connecting the outer surface of the housing to the hollow inner cavity 24. The method of opening and closing the left housing 21 and the right housing 22 is prior art and will not be described in detail here.

[0046] The method for preparing single-sided magnetic three-dimensional woven fabric based on the above-mentioned external weft insertion component 2 is as follows: Figure 2 As shown, it includes the following steps:

[0047] S1: The warp yarn x on the warp tube 5 travels in the weaving direction through the gap between the reeds 3;

[0048] S2: The connecting warp yarn z on the connecting warp yarn tube 4 passes through the reed teeth in the steel reed 3 and moves up and down under the drive of the reed teeth. In one longitudinal unit movement, the connecting warp yarn z moves to below the warp yarn x under the drive of the reed teeth of the steel reed 3, and the third weft yarn y3 enters between the two adjacent warp yarns x above the connecting warp yarn z under the guidance of the shuttle.

[0049] S3: The hook needle on the external weft guide component 2 moves the connecting warp yarn z around the outer circumference of the winding shaft 23 of the external weft guide component 2 below, and then guides the second weft yarn y2 through the hollow inner cavity 24 of the external weft guide component 2. Subsequently, the left shell 21 and right shell 22 of the external weft guide component 2 open and move away from the connecting warp yarn z, so that the connecting warp yarn z comes out from the external weft guide component 2. At the same time, the second weft yarn y2 comes out from the notch 25 on the external weft guide component 2 and moves away from the external weft guide component 2, so that the connecting warp yarn z wraps around the second weft yarn y2 once, completing the wrapping on the second weft yarn y2.

[0050] To enhance the adhesion of the warp yarn z to the winding shaft 23, a conductive block (not shown in the figure) is provided inside the housing of the weft guide component 2. Since the warp yarn z is made of magnetic yarn, the conductive block can improve the adhesion of the warp yarn z to the winding shaft 23. The conductive block is a circular notch, and its notch 25 corresponds to the notch 25 on the housing. When the warp yarn z is wound on the weft guide component 2, energizing the conductive block can increase the clamping force on the warp yarn z. When the left housing 21 and right housing 22 of the external weft guide component 2 open and the housing moves away from the warp yarn z, the conductive block is de-energized, completing one round of winding of the warp yarn z on the second weft yarn y2.

[0051] To further avoid damage to the yarn, a protective sleeve (not shown in the figure) is provided on the outer periphery of the housing. The protective sleeve, the housing, and the winding shaft 23 form a cavity for accommodating the yarn.

[0052] S4: Then, the connecting warp yarn z moves upward under the action of the reed teeth, passing around the third weft yarn y3 in sequence to the upper external weft guide component 2. The connecting warp yarn z wraps around the outer periphery of the upper external weft guide component 2 once, and then guides the first weft yarn y1 through the hollow inner cavity 24 on the external weft guide component 2. Subsequently, the external weft guide component 2 opens and separates from the connecting warp yarn z. The connecting warp yarn z comes out of the external weft guide component 2, and at the same time, the first weft yarn y1 comes out from the notch 25 on the external weft guide component 2. Thus, the connecting warp yarn z wraps around the first weft yarn y1 once, completing the wrapping on the first weft yarn y1.

[0053] S5: Then, the warp yarn z, driven by the reed 3, enters the next longitudinal unit, and the above operation is repeated until the yarn is woven as shown. Figure 1 The single-sided magnetic three-dimensional fabric 1 is shown.

[0054] Example 2

[0055] The difference between this embodiment and Embodiment 1 is that it includes two layers: a decorative layer and an attachment layer, but does not include a support layer. The winding method of the warp yarn z is as follows: Figure 4 As shown.

[0056] The preparation method is as follows:

[0057] The preparation method in this embodiment differs from that in the previous embodiment in that: S4: Then the warp yarn z is connected to the upper external weft guide component 2. The warp yarn z wraps around the outer periphery of the upper external weft guide component 2 once. Then the first weft yarn y1 is guided through the hollow inner cavity 24 on the external weft guide component 2. Subsequently, the external weft guide component 2 opens and separates from the warp yarn z. The warp yarn z comes out from the external weft guide component 2. At the same time, the first weft yarn y1 comes out from the notch 25 on the external weft guide component 2. Thus, the warp yarn z wraps around the first weft yarn y1 once, completing the wrapping on the first weft yarn y1.

[0058] S5: Then, the warp yarn z, driven by the reed 3, enters the next longitudinal unit, and the above operation is repeated until the yarn is woven as shown. Figure 4 The single-sided magnetic three-dimensional fabric 1 is shown.

[0059] Example 3

[0060] The difference between this embodiment and Embodiment 1 is that it includes a decorative layer, two support layers, and an attachment layer, and the winding method of the warp yarns is as follows: Figure 5 As shown, the warp yarns between the decorative layer and the support layer are denoted as x1; the warp yarns between the support layer and the attachment layer are denoted as x3; and the warp yarns between support layer y3 and support layer y4 are denoted as x2. Specifically, warp yarn x2 and the third weft yarns y3 and y4 are high-strength yarns, warp yarns x1 and x3 and the first weft yarn y1 are decorative yarns, and the second weft yarn y2 and the connecting warp yarn z are magnetic yarns.

[0061] The preparation method in this embodiment differs from that in the previous embodiment in that: S5: Then, the warp yarn z is driven by the reed 3 to enter the next longitudinal unit, and then it is wound from top to bottom until the winding of the longitudinal unit is completed, which completes one unit cycle. The above operation is repeated until it is woven into the shape shown. Figure 5 The single-sided magnetic three-dimensional fabric shown.

[0062] Example 4

[0063] The difference between this embodiment and embodiment 1 is that: the warp yarn x and the first weft yarn y1 are decorative yarns, the second weft yarn y2, the third weft yarn y3 and the connecting warp yarn z are strong yarns, and a rubber magnetic plate is bonded to the lower surface of the second weft yarn y2.

[0064] Example 5

[0065] A single-layer fabric is woven using a traditional plain weave process, wherein the warp yarn x is a high-strength yarn and the weft yarn is a magnetic yarn, and the rest is the same as in Example 1.

[0066] The properties of the strong yarn, magnetic yarn and decorative yarn involved in the above different embodiments are all the same. The fabric width is 20 cm. In a 10*10 cm fabric, the density of single layer warp yarn, weft yarn and spliced ​​warp yarn is 5, 3 and 6 yarns / cm, respectively.

[0067] The properties of the fabrics obtained in Examples 1-5 were tested, and the test results are shown in Table 1.

[0068] Table 1. Fabric performance test results

[0069]

[0070] The decorative yarns used in the first weft yarn y1 of Examples 1 and 4 above can be decorated with digital printing and embroidery, which has a certain aesthetic effect. However, due to the use of rubber magnetic plates in Example 4, its weight and wearability are worse than those in Example 1. Example 5 uses traditional two-dimensional fabrics with a simple structure, which cannot achieve a good decorative effect while taking into account functionality, and the outer surface feels rough.

[0071] In this application, the skin-fitting property is achieved by using magnetic yarns interwoven within the fabric, resulting in a more comfortable wearing experience for the three-dimensional fabric. When the three-dimensional fabric of this invention is used for partial decoration on the fabric, the thickness of the three-dimensional fabric itself can achieve a certain three-dimensional effect. In Examples 1, 2, and 3, it can be observed that the external weft winding component used in this invention can wind the weft yarns of two to four layers of three-dimensional fabric. However, due to the smaller number of layers in Example 2, although it satisfies the functions of decoration and attachment, its strength is relatively weak. The four-layer structure of Example 3 is compact, and although it has higher strength and magnetism, its breathability and weight are not as good as the three-layer structure of Example 1. Considering the decorative function of the fabric of this invention, Example 1 with a three-layer structure is the best. Furthermore, the fabric of this invention can have more layers, and in other cases, the method of this invention can be extended and applied according to specific circumstances.
