The first weft yarn y1 is a decorative yarn, the warp yarn x and the third weft yarn y3 are strong yarns, and the second weft yarn y2 and the binding warp yarn z are magnetic yarns. The three-dimensional woven fabric is used in conjunction with the attached fabric, and the attached fabric is provided with paramagnetic metal yarns.

[0045] In the prior art, the winding method of the warp yarn on the weft yarn in the three-dimensional structure is half-circle winding, and the overall structure has poor reliability and poor mechanical properties. In order to achieve full-circle winding of the weft yarn, the present application provides an additional weft passing component 2, such as Figure 3 As shown, the housing includes a left housing 21 and a right housing 22, a winding shaft 23 is formed between the left housing 21 and the right housing 22, and the left housing 21 and the right housing 22 can be opened and closed to allow the yarn on the winding shaft 23 to be separated from the housing, a hollow inner cavity 24 is provided on the housing, and the hollow inner cavity 24 is arranged in the winding shaft 23, and a notch 25 is provided on the housing, and the notch 25 connects the outer surface of the housing with the hollow inner cavity 24. The opening and closing method of the left housing 21 and the right housing 22 is a prior art and will not be described in detail here.

[0046] A method for preparing a single-sided magnetic three-dimensional woven fabric based on the above-mentioned additional weft-passing component 2, such as Figure 2 As shown, the following steps are included:

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

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

[0049] S3: The hook on the external weft passing component 2 is moved to drive the tying warp yarn z to wind around the outer circumference of the winding shaft 23 of the external weft passing component 2 below for one circle, and then the second weft yarn y2 is guided to pass through the hollow inner cavity 24 on the external weft passing component 2, and then the left shell 21 and the right shell 22 of the external weft passing component 2 are opened, and the shells are away from the tying warp yarn z, so that the tying warp yarn z escapes from the external weft passing component 2, and at the same time, the second weft yarn y2 escapes from the notch 25 on the external weft passing component 2 and is away from the external weft passing component 2, so that the tying warp yarn z is wrapped around the second weft yarn y2 for one circle, completing the winding on the second weft yarn y2;

[0050] In order to enhance the adhesion of the binding warp yarn z on the winding shaft 23, a conductive block (not shown in the figure) is arranged in the shell of the weft passing component 2. Since the binding warp yarn adopts magnetic yarn, the conductive block can enhance the adhesion of the binding warp yarn on the winding shaft 23. The conductive block is in a circular shape, and its notch 25 corresponds to the notch 25 on the shell. When the binding warp yarn z is wound on the weft passing component 2, the conductive block can be energized to enhance the clamping force on the binding warp yarn z; when the left shell 21 and the right shell 22 of the additional weft passing component 2 are opened and the shell is away from the binding warp yarn z, the conductive block is de-energized, and the binding warp yarn z is wound around the second weft yarn y2.

[0051] In order to further avoid damage to the yarn, a protective sleeve (not shown in the figure) is arranged on the outer periphery of the shell, and a chamber for accommodating the yarn is formed between the protective sleeve, the shell and the winding shaft 23.

[0052] S4: Then the binding warp yarn z moves upward under the drive of the reed teeth, passes around the third weft yarn y3 in turn and reaches the upper external weft passing component 2, the binding warp yarn z is wound around the outer circumference of the upper external weft passing component 2 for one circle, and then the first weft yarn y1 is guided to pass through the hollow inner cavity 24 on the external weft passing component 2, and then the external weft passing component 2 is opened and separated from the binding warp yarn z, the binding warp yarn z escapes from the external weft passing component 2, and at the same time, the first weft yarn y1 escapes from the notch 25 on the external weft passing component 2, so that the binding warp yarn z is wrapped around the first weft yarn y1 for one circle, completing the winding on the first weft yarn y1;

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

[0054] Example 2

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

[0056] The preparation method is as follows:

[0057] The preparation method in this embodiment is different from that in the embodiment in that: S4: the warp yarn z is then tied to the upper additional weft passing component 2, the tying warp yarn z is wound around the outer circumference of the upper additional weft passing component 2 for one circle, and then the first weft yarn y1 is guided to pass through the hollow inner cavity 24 on the additional weft passing component 2, and then the additional weft passing component 2 is opened and separated from the tying warp yarn z, the tying warp yarn z escapes from the additional weft passing component 2, and at the same time, the first weft yarn y1 escapes from the notch 25 on the additional weft passing component 2, so that the tying warp yarn z is wound around the first weft yarn y1 for one circle, and the winding on the first weft yarn y1 is completed;

[0058] S5: Then the binding warp yarn z enters the next longitudinal unit under the drive of the reed 3, and the above operation is repeated until the weaving is as follows: 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 supporting layers and an attachment layer, and the winding method of the binding warp yarn is as follows: Figure 5 As shown, the warp yarn between the decorative layer and the supporting layer is marked as x1; the warp yarn between the supporting layer and the attachment layer is marked as x3; the warp yarn between the supporting layer y3 and the supporting layer y4 is marked as x2. Among them, the warp yarn x2 and the third weft yarns y3 and y4 are made of strong yarns, the warp yarns x1, x3 and the first weft yarn y1 are made of decorative yarns, and the second weft yarn y2 and the binding warp yarn z are made of magnetic yarns.

[0061] The preparation method in this embodiment is different from that in the embodiment in that: S5: Then the binding warp yarn z enters the next longitudinal unit under the drive of the reed 3, and then is wound from top to bottom until the winding of the longitudinal unit is completed, that is, a complete unit cycle is completed, and the above operation is repeated until the weaving is as follows: Figure 5 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] The single-layer fabric is woven by conventional plain weave technology, wherein the warp yarn x is a strong 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 consistent. The fabric width is 20 cm. In the 10*10 cm fabric, the density of the single-layer warp yarn, weft yarn and binding warp yarn is 5, 3 and 6 yarns / cm.

[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 surface of the decorative yarn used for the first weft yarn y1 in the above-mentioned embodiments 1 and 4 can be decoratively modified by digital printing and embroidery, which has a certain aesthetic effect, but due to the use of the rubber magnetic plate in embodiment 4, its gram weight and wearability are worse than those in embodiment 1. Embodiment 5 uses traditional two-dimensional fabrics with a single structure, which cannot have a good decorative effect on the basis of taking into account functionality, and the outer surface feels rough.

[0071] In the present application, the skin-fitting property is achieved by using magnetic yarns inserted therein, so that the three-dimensional fabric has a more comfortable wearing performance; when the three-dimensional fabric of the present invention is used for partial decoration on the fabric, the thickness of the three-dimensional fabric itself can achieve a certain three-dimensional effect. It can be observed in Examples 1, 2, and 3 that the additional weft-passing component used in the present invention can wind the weft yarns of two to four layers of three-dimensional fabrics, but because the number of structural layers of Example 2 is relatively small, although it meets the functions of decoration and attachment, its strength is relatively weak, and the four-layer structure of Example 3 is compact, although it has higher strength and magnetism, but the air permeability and gram weight are not as good as the three-layer structure of Example 1; considering the decorative effect of the fabric of the present invention, Example 1 with a three-layer structure is the best, and the fabric of the present invention can have more layers, and in other cases, the method of the present invention can be expanded and applied according to specific circumstances.
