Description

Technical Field

[0001] The present application relates to the field of knitting technology, and more specifically, to a three-dimensional knitted fabric and a knitting method of the three-dimensional knitted fabric. Background Art

[0002] Knitted fabrics are composed of loops, which give them a certain degree of ductility and elasticity. Knitted fabrics can be made into soft and easy-to-bend fabrics while having a certain connection strength. Knitted fabrics can also use the arrangement of loops to form pores to meet special functional and appearance requirements.

[0003] Traditional knitted fabrics are two-dimensional, that is, they are extended in width and length on one plane. With the development of technology, knitted fabrics are gradually applied to more fields, leading to the demand for three-dimensional knitted fabrics.

[0004] At present, there are mainly two types of three-dimensional knitted fabrics and their weaving methods:

[0005] The first one is to combine two or more layers of flat fabrics together to form a three-dimensional knitted fabric with a certain thickness. The thickness of the three-dimensional knitted fabric is limited by the structure and process of the knitting machine, and it is impossible to increase the number of layers (thickness) of the three-dimensional knitted fabric indefinitely; in addition, the more layers there are, the more complex the structure and knitting method of the three-dimensional knitted fabric will be, and the more product defects will increase.

[0006] The second type is to form a hollow outer layer with a three-dimensional shape through a knitting machine or hand-crocheting technique, that is, a hollow three-dimensional knitted fabric. This hollow three-dimensional knitted fabric cannot be used in scenes that require a solid structure.

[0007] In summary, how to design a three-dimensional knitted fabric so as to realize that the three-dimensional knitted fabric has a solid structure and can be infinitely extended in the thickness direction is a problem that needs to be solved urgently by those skilled in the art.

[0079] For ease of understanding, the technical terms involved in this application are explained and described below.

[0080] Knitted fabrics are a collection of spun yarns that are bent into loops, strung together longitudinally and connected transversely. The basic unit of knitted fabrics is the loop. Knitted fabrics mainly include weft knitted fabrics and warp knitted fabrics.

[0081] A row of stitches is a row of stitches in a pointer fabric arranged in the transverse direction of the knitted fabric.

[0082] A wale is a row of loops in a pointer fabric that is arranged in the longitudinal direction of the knitted fabric.

[0083] A series connection (or series connection) means that one of two adjacent coils is sleeved on the other, that is, one of the two adjacent coils passes through the other.

[0084] Weft knitted fabrics are knitted fabrics made by forming coils in the horizontal direction on a weft knitting machine with one or more yarns, and then interlacing the coils. The basic structures of weft knitted fabrics include: plain weft structure, rib structure, double reverse structure and double rib structure.

[0085] like Figure 1 As shown, the coil of the weft knitted fabric includes a coil stem (①-②-③-④-⑤) and an extension line (⑤-⑥-⑦), wherein the straight section (①-②) and the straight section (④-⑤) of the coil stem are called coil columns, the arc section (②-③-④) is called a needle knitting arc, and the extension line (⑤-⑥-⑦) is also called a sinking arc. The extension line (⑤-⑥-⑦) is used to connect two coils adjacent in the horizontal direction. The two adjacent coils are connected in series, which means that the coil stem of one coil passes through the coil stem of another coil, that is, the coil stem of one coil passes through the space enclosed by the coil stem of another coil.

[0086] Weft plain stitch, also known as plain stitch, is one of the basic structures of weft knitted fabrics. It is made of continuous unit coils that are interlaced in one direction. The coils in the weft plain stitch are connected horizontally and interlaced vertically. The size / properties / structure of each coil in the weft plain stitch is exactly the same. It is a two-dimensional (single-layer) structure.

[0087] The tuck structure is one of the basic coil structures of the weft plain needle weave. In addition to the closed hanging arc on some coils, there is one or more unclosed hanging arcs. The old coil with closed hanging arcs forms an elongated coil. It can be understood as changing the structural size of a coil to make two coils that should have been set in two positions form a loop together at the same position.

[0088] Rib structure is the basic structure of double-sided weft knitted fabrics. Rib structure is formed by the arrangement of the front coil wale and the back coil wale in a certain structure. Each horizontal row of rib structure is woven by a spun yarn, weaving both the front coil and the back coil. The front and back sides of the fabric are the same, both showing the appearance of the front coil.

[0089] Double-purl weave is composed of alternating rows of front and back coils. Both sides of the fabric present the appearance of the back of the weft plain weave. Due to the inclination of the coil cylinder surface, the double-purl weave shortens the fabric longitudinally, increasing the longitudinal density and thickness of the fabric. The fabric has greater longitudinal extensibility and elasticity, but it is easy to fall apart along the forward (or reverse) knitting direction. Double-purl weave fabrics feel thick and have good warmth retention.

[0090] Double rib weave, also known as cotton wool weave, is made of two rib weaves interlaced and laminated. The wale of coils of one rib weave is arranged between the wale of coils of another rib weave, and the reverse sides of the coils are covered with each other. Therefore, the front and reverse sides of the double rib weave fabric have the form of the front coils of weft knitted plain knitted fabric, showing longitudinal stripes and good integrity. The ductility and elasticity of double rib weave are smaller than those of rib weave, and the coils are less likely to fall apart.

[0091] In order to realize that a three-dimensional knitted fabric has a solid structure and that the three-dimensional knitted fabric can extend infinitely in the thickness direction, an embodiment of the present application provides a three-dimensional knitted fabric and a knitting method for the three-dimensional knitted fabric.

[0092] Combine the following Figure 1-Figure 12 , first introduce the three-dimensional knitted fabric provided in the embodiment of the present application.

[0093] like Figure 7-Figure 10 As shown, the three-dimensional knitted fabric provided in the embodiment of the present application includes: a first layer of coils 100 and a second layer of coils 200, the first layer of coils 100 and the second layer of coils 200 are distributed sequentially along the thickness direction of the three-dimensional knitted fabric, and at least one coil 1 in the first layer of coils 100 and at least one coil 1 in the second layer of coils 200 are connected in series.

[0094] It can be understood that at least one coil 1 in the first layer of coils 100 and at least one coil 1 in the second layer of coils 200 are connected in series, that is, at least one coil 1 in the first layer of coils 100 passes through at least one coil 1 in the second layer of coils 200. For the specific structure of the series connection, please refer to the above text, which will not be repeated here.

[0095] It should be noted that the first layer coil 100 can be called a lower layer coil, and the second layer coil 200 can be called an upper layer coil. The lower layer coil and the upper layer coil are two adjacent layers of coils.

[0096] The thickness direction of the three-dimensional knitted fabric is the thickness direction of the first layer coil 100 and also the thickness direction of the second layer coil 200. For ease of description, the thickness direction may be referred to as the Z direction. The second layer coil 200 and the first layer coil 200 are connected in series in the Z direction.

[0097] In the three-dimensional knitted fabric provided in the embodiment of the present application, a three-dimensional knitted fabric with a solid structure can be obtained by sequentially distributing the first layer coils 100 and the second layer coils 200 in the thickness direction, and the three-dimensional knitted fabric is extended in the thickness direction.

[0098] In the three-dimensional knitted fabric provided in the embodiment of the present application, by adjusting the position and number of the coil 1 string, the connection strength of different parts inside the three-dimensional knitted fabric can be adjusted to obtain a three-dimensional knitted fabric with different physical (mechanical) properties, which can meet the needs of different industries and scenarios.

[0099] In the three-dimensional knitted fabric provided in the embodiment of the present application, the first layer of coils 100 and the second layer of coils 200 can both be weft knitting structures, for example, weft plain stitch, rib stitch, double reverse stitch, or double rib stitch. For the convenience of knitting, the first layer of coils 100 and the second layer of coils 200 can both be weft plain stitch.

[0100] In the case where both the first layer coil 100 and the second layer coil 200 are weft knitted structures, as shown in FIG. Figure 7-Figure 10 As shown, the first layer of coils 100 and the second layer of coils 200 each include six coil rows, which are: a first coil row 01, a second coil row 02, a third coil row 03, a fourth coil row 04, a fifth coil row 05, and a sixth coil row 06.

[0101] The first layer coil 100 will be described below.

[0102] like Figure 2 As shown, there are six coils 1 in the first coil row 01. The six coils 1 are connected in sequence along the transverse direction. For ease of description, the transverse direction can be recorded as the X direction, and the Z direction is perpendicular to the X direction. The transverse direction can be called the width direction of the three-dimensional knitted fabric.

[0103] Correspondingly, the number of stitches 1 in the second stitch row 02, the third stitch row 03, the fourth stitch row 04, the fifth stitch row 05 and the sixth stitch row 06 are all six.

[0104] Of course, the number of the stitches 1 in the above-mentioned coil row (the first coil row 01, the second coil row 02, the third coil row 03, the fourth coil row 04, the fifth coil row 05, or the sixth coil row 06) may be one, two, three, four, five or more than seven, which is selected according to actual conditions, and is not limited in this embodiment of the present application.

[0105] like Figure 3 and Figure 4As shown, the first coil row 01 and the second coil row 02 are sequentially distributed along the longitudinal direction. Correspondingly, the third coil row 03, the fourth coil row 04, the fifth coil row 05 and the sixth coil row 06 are also sequentially distributed along the longitudinal direction.

[0106] For ease of description, the longitudinal direction may be recorded as the Y direction. The Y direction and the X direction are perpendicular to each other, and the Z direction is perpendicular to the plane formed by the X direction and the Y direction.

[0107] like Figure 5 and Figure 6 As shown, each coil 1 in the second coil row 02 is connected in series with each coil 1 in the first coil row 01, each coil 1 in the third coil row 03 is connected in series with each coil 1 in the second coil row 02, each coil 1 in the fourth coil row 04 is connected in series with each coil 1 in the third coil row 03, each coil 1 in the fifth coil row 05 is connected in series with each coil 1 in the fourth coil row 04, and each coil 1 in the sixth coil row 06 is connected in series with each coil 1 in the fifth coil row 05.

[0108] In other embodiments, in the first layer of coils 100, it is also possible to select that in two adjacent horizontal rows of coils, a partial coil 1 of one is connected in series with a partial coil 1 of the other, and another partial coil 1 of one is not connected in series with another partial coil 1 of the other.

[0109] In other embodiments, in the first layer of coils 100, at least one coil 1 of one of two adjacent coil rows may be connected in series with at least one coil 1 of the other, and at least one coil 1 of one of the two adjacent coil rows may be connected in series with a coil 1 of the other coil row. In this way, a tuck structure may be formed in the first layer of coils 100.

[0110] The second layer coil 200 is described below. Figure 7-Figure 10 As shown, the first coil row 01 of the second layer coil 200 is set at a position directly above the first coil row 01 of the first layer coil 100. It can be understood that the coil 1 of the first coil row 01 of the first layer coil 100 and the coil 1 of the first coil row 01 of the second layer coil 200 are not connected in series.

[0111] It should be noted that, in the Z direction, the distance between the set position and the first coil row 01 of the first layer of coils 100 depends on the thickness of the wire and the size of the coils.

[0112] The second coil row 02 of the second layer coil 200 is set at a position directly above the second coil row 02 of the first layer coil 100. The second coil row 02 of the second layer coil 200 is connected in series with the first coil row 01 of the second layer coil 200, and is connected in series with the first coil row 01 of the first layer coil 100, that is, the coil 1 of the second coil row 02 of the second layer coil 200 passes through the coil 1 of the first coil row 01 of the second layer coil 200, and the coil 1 of the second coil row 02 of the second layer coil 200 passes through the coil 1 of the first coil row 01 of the first layer coil 100. It can be understood that the coil 1 of the second coil row 02 of the second layer coil 200 first passes through the coil of the first coil row 01 of the second layer coil 200, and then passes through the coil of the first coil row 01 of the first layer coil 100.

[0113] Each coil 1 of the second coil row 02 of the second layer coil 200 is connected in series with each coil 1 of the first coil row 01 of the second layer coil 200, and each coil 1 of the second coil row 02 of the second layer coil 200 is connected in series with each coil 1 of the first coil row 01 of the first layer coil 100.

[0114] The third coil row 03 of the second layer coil 200 is set at a position just above the third coil row 03 of the first layer coil 100. The third coil row 03 of the second layer coil 200 is connected in series with the second coil row 02 of the second layer coil 200 and is connected in series with the second coil row 02 of the first layer coil 100, that is, the coil 1 of the third coil row 03 of the second layer coil 200 passes through the coil 1 of the second coil row 02 of the second layer coil 200, and the coil 1 of the third coil row 03 of the second layer coil 200 passes through the coil 1 of the second coil row 02 of the first layer coil 100. It can be understood that the coil 1 of the third coil row 03 of the second layer coil 200 first passes through the coil 1 of the second coil row 02 of the second layer coil 200, and then passes through the coil 1 of the second coil row 02 of the first layer coil 100.

[0115] Each coil 1 of the third coil row 03 of the second layer coil 200 is connected in series with each coil 1 of the second coil row 02 of the second layer coil 200, and each coil 1 of the third coil row 03 of the second layer coil 200 is connected in series with each coil 1 of the second coil row 02 of the first layer coil 100.

[0116] The fourth coil row 04 of the second layer coil 200 is set at a position just above the fourth coil row 04 of the first layer coil 100. The fourth coil row 04 of the second layer coil 200 is connected in series with the third coil row 03 of the second layer coil 200 and is connected in series with the third coil row 03 of the first layer coil 100, that is, the coil 1 of the fourth coil row 04 of the second layer coil 200 passes through the coil 1 of the third coil row 03 of the second layer coil 200, and the coil 1 of the fourth coil row 04 of the second layer coil 200 passes through the coil 1 of the third coil row 03 of the first layer coil 100. It can be understood that the coil 1 of the fourth coil row 04 of the second layer coil 200 first passes through the coil 1 of the third coil row 03 of the second layer coil 200, and then passes through the coil 1 of the third coil row 03 of the first layer coil 100.

[0117] Each coil 1 of the fourth coil row 04 of the second layer coil 200 is connected in series with each coil 1 of the third coil row 03 of the second layer coil 200, and each coil 1 of the fourth coil row 04 of the second layer coil 200 is connected in series with each coil 1 of the third coil row 03 of the first layer coil 100.

[0118] The fifth coil row 05 of the second layer coil 200 is set at a position just above the fifth coil row 05 of the first layer coil 100. The fifth coil row 05 of the second layer coil 200 is connected in series with the fourth coil row 04 of the second layer coil 200 and is connected in series with the fourth coil row 04 of the first layer coil 100, that is, the coil 1 of the fifth coil row 05 of the second layer coil 200 passes through the coil 1 of the fourth coil row 04 of the second layer coil 200, and the coil 1 of the fifth coil row 05 of the second layer coil 200 passes through the coil 1 of the fourth coil row 04 of the first layer coil 100. It can be understood that the coil 1 of the fifth coil row 05 of the second layer coil 200 first passes through the coil 1 of the fourth coil row 04 of the second layer coil 200, and then passes through the coil 1 of the fourth coil row 04 of the first layer coil 100.

[0119] Each coil 1 of the fifth coil row 05 of the second layer coil 200 is connected in series with each coil 1 of the fourth coil row 04 of the second layer coil 200, and each coil 1 of the fifth coil row 05 of the second layer coil 200 is connected in series with each coil 1 of the fourth coil row 04 of the first layer coil 100.

[0120] The sixth coil row 06 of the second layer coil 200 is set at a position just above the sixth coil row 06 of the first layer coil 100. The sixth coil row 06 of the second layer coil 200 is connected in series with the fifth coil row 05 of the second layer coil 200 and is connected in series with the fifth coil row 05 of the first layer coil 100, that is, the coil 1 of the sixth coil row 06 of the second layer coil 200 passes through the coil 1 of the fifth coil row 05 of the second layer coil 200, and the coil 1 of the sixth coil row 06 of the second layer coil 200 passes through the coil 1 of the fifth coil row 05 of the first layer coil 100. It can be understood that the coil 1 of the sixth coil row 06 of the second layer coil 200 first passes through the coil 1 of the fifth coil row 05 of the second layer coil 200, and then passes through the coil 1 of the fifth coil row 05 of the first layer coil 100.

[0121] Each coil 1 of the sixth coil row 06 of the second layer coil 200 is connected in series with each coil 1 of the fifth coil row 05 of the second layer coil 200 , and each coil 1 of the sixth coil row 06 of the second layer coil 200 is connected in series with each coil 1 of the fifth coil row 05 of the first layer coil 100 .

[0122] In the above embodiment, the nth coil row of the first layer coil 100 and the nth coil row of the second layer coil 200 are arranged opposite to each other; wherein n is a positive integer, which is not greater than the number of coil rows of the second layer coil 200 and not greater than the number of coil rows of the first layer coil 100. Further, the n'+1th coil row of the second layer coil 200 is connected in series with the n'th coil row of the first layer coil 100; wherein n' is a positive integer, which is not greater than the number of coil rows of the second layer coil 200 and not greater than the number of coil rows of the first layer coil 100.

[0123] In the above embodiment, the number of coil rows of the first coil layer 100 is the same as the number of coil rows of the second coil layer 200, the number of coils in any two coil rows in the first coil layer 100 is the same, the number of coils in any two coil rows in the second coil layer 200 is the same, and the number of coils in the coil rows in the first coil layer 100 is the same as the number of coils in the coil rows in the second coil layer 200.

[0124] In the above embodiment, in the second layer coil 200, each coil 1 in the other coil rows except the first coil row 01 is connected in series with the corresponding coil in the first layer coil 100. Of course, it is also possible to select that in the second layer coil 200, some coils 1 in the other coil rows except the first coil row 01 are connected in series with the corresponding coil 1 in the first layer coil 100, and another part of the coils 1 in the other coil rows except the first coil row 01 are not connected in series with the coil 1 in the first layer coil 100.

[0125] In some other embodiments, the number of coil rows of the first layer coil 100 may be different from the number of coil rows of the second layer coil 200 , for example, the number of coil rows of the first layer coil 100 may be greater than or less than the number of coil rows of the second layer coil 200 .

[0126] In some other embodiments, the number of coils in the horizontal row of coils in the first layer of coils 100 is different from the number of coils in the horizontal row of coils in the second layer of coils 200. Exemplarily, the number of coils in the horizontal row of coils in the second layer of coils 200 and the number of coils in the horizontal row of coils in the first layer of coils 100, which are sequentially distributed along the Z direction, are different. In this case, it can be selected that some coils in the horizontal row of coils in the second layer of coils 200 are connected in series with the corresponding coils in the first layer of coils 100, and some coils in the second horizontal row of coils in the second layer of coils 200 are not connected in series with the coils in the first layer of coils 100.

[0127] In some other embodiments, at least two rows of coils in the first layer of coils 100 have different numbers of coils; and / or at least two rows of coils in the first layer of coils 100 have the same number of coils.

[0128] Correspondingly, the number of coils in at least two rows of coils in the second layer of coils 200 is different; and / or the number of coils in at least two rows of coils in the second layer of coils 200 is the same.

[0129] In the present application embodiment, Figure 7 and Figure 8 As shown, the forming direction of the second layer coil 200 (the distribution direction of the previous coil row and the next coil row) is the same as the forming direction of the first layer coil 100 (the distribution direction of the previous coil row and the next coil row). On this basis, in addition to the aforementioned stringing method (the n'+1th coil row of the second layer coil 200 is connected in series with the n'th coil row of the first layer coil 100), the nth coil row of the second layer coil 200 can also be connected in series with the nth coil row of the first layer coil 100, where n is a positive integer, which is not greater than the number of coil rows of the second layer coil 200 and not greater than the number of coil rows of the first layer coil 100.

[0130] Exemplarily, the first row of coils of the second layer of coils 200 is connected in series with the first row of coils of the first layer of coils 100, the second row of coils of the second layer of coils 200 is connected in series with the second row of coils of the first layer of coils 100, the third row of coils of the second layer of coils 200 is connected in series with the third row of coils of the first layer of coils 100, the fourth row of coils of the second layer of coils 200 is connected in series with the fourth row of coils of the first layer of coils 100, the fifth row of coils of the second layer of coils 200 is connected in series with the fifth row of coils of the first layer of coils 100, and the sixth row of coils of the second layer of coils 200 is connected in series with the sixth row of coils of the first layer of coils 100.

[0131] When the forming direction of the second layer coil 200 is the same as that of the first layer coil 100, in addition to the distribution method described above (the nth coil row of the first layer coil 100 and the nth coil row of the second layer coil 200 are arranged opposite to each other), the nth coil row of the second layer coil 200 and the nth coil row of the first layer coil 100 may also be arranged in a staggered manner, wherein n is a positive integer, which is not greater than the number of coil rows of the second layer coil 200 and not greater than the number of coil rows of the first layer coil 100.

[0132] Exemplarily, the first coil row 01 of the second layer of coils 200 is set at a position just above the second coil row 02 of the first layer of coils 100, that is, the first coil row 01 of the second layer of coils 200 and the first coil row 01 of the first layer of coils 100 are staggered. In this way, the first coil row 01 of the second layer of coils 200 corresponds to the second coil row 02 of the first layer of coils 100. In this case, it can be selected that at least one coil 1 of the first coil row 01 of the second layer of coils 200 and at least one coil 1 of the first coil row 01 of the first layer of coils 100 are connected in series, or the first coil row 01 of the second layer of coils 200 and the first coil row 01 of the first layer of coils 100 are not connected in series.

[0133] By analogy, the second coil row 02 of the second layer coil 200 corresponds to the third coil row 03 of the first layer coil 100 (the second coil row 02 of the second layer coil 200 and the second coil row 02 of the first layer coil 100 are staggered), the third coil row 03 of the second layer coil 200 corresponds to the fourth coil row 04 of the first layer coil 100 (the third coil row 03 of the second layer coil 200 and the third coil row 03 of the first layer coil 100 are staggered), the fourth coil row 04 of the second layer coil 200 corresponds to the fifth coil row 04 of the first layer coil 100. 05 of the second layer coil 200 (the fourth coil row 04 of the second layer coil 200 and the fourth coil row 04 of the first layer coil 100 are arranged offset), the fifth coil row 05 of the second layer coil 200 and the sixth coil row 06 of the first layer coil 100 correspond (the fifth coil row 05 of the second layer coil 200 and the fifth coil row 05 of the first layer coil 100 are arranged offset), and the sixth coil row 06 of the second layer coil 200 extends relative to the first layer coil 100 (the sixth coil row 06 of the second layer coil 200 and the sixth coil row 06 of the first layer coil 100 are arranged offset).

[0134] In some other embodiments, the first coil row 01 of the second layer of coils 200 may be set at a position directly above the third coil row 03, the fourth coil row 04, the fifth coil row 05 or the sixth coil row 06 of the first layer of coils 100. Accordingly, the second coil row 02, the third coil row 03, the fourth coil row 04, the fifth coil row 05 and the sixth coil row 06 of the second layer of coils 200 move in sequence with the first coil row 01 of the second layer of coils 200, which will not be described in detail herein.

[0135] like Fig. 9 and Fig.10 As shown, the molding direction of the second layer coil 200 may also be opposite to the molding direction of the first layer coil 100 .

[0136] The first coil row 01 of the second layer coil 200 and the sixth coil row 06 of the first layer coil 100 are connected in series.

[0137] The second coil row 02 of the second layer coil 200 is connected in series with the first coil row 01 of the second layer coil 200, and the second coil row 02 of the second layer coil 200 is connected in series with the fifth coil row 05 of the first layer coil 100, that is, the coil 1 of the second coil row 02 of the second layer coil 200 passes through the coil 1 of the first coil row 01 of the second layer coil 200, and the coil 1 of the second coil row 02 of the second layer coil 200 passes through the coil 1 of the fifth coil row 05 of the first layer coil 100. It can be understood that the coil 1 of the second coil row 02 of the second layer coil 200 first passes through the coil 1 of the first coil row 01 of the second layer coil 200, and then passes through the coil 1 of the fifth coil row 05 of the first layer coil 100.

[0138] The third coil row 03 of the second layer coil 200 is connected in series with the second coil row 02 of the second layer coil 200, and the third coil row 03 of the second layer coil 200 is connected in series with the fourth coil row 04 of the first layer coil 100. It can be understood that the coil 1 of the third coil row 03 of the second layer coil 200 first passes through the coil 1 of the second coil row 02 of the second layer coil 200, and then passes through the coil 1 of the fourth coil row 04 of the first layer coil 100.

[0139] The fourth coil row 04 of the second layer coil 200 is connected in series with the third coil row 03 of the second layer coil 200, and the fourth coil row 04 of the second layer coil 200 is connected in series with the third coil row 03 of the first layer coil 100. It can be understood that the coil 1 of the fourth coil row 04 of the second layer coil 200 first passes through the coil 1 of the third coil row 03 of the second layer coil 200, and then passes through the coil 1 of the third coil row 03 of the first layer coil 100.

[0140] The fifth coil row 05 of the second layer coil 200 is connected in series with the fourth coil row 04 of the second layer coil 200, and the fifth coil row 05 of the second layer coil 200 is connected in series with the second coil row 02 of the first layer coil 100. It can be understood that the coil 1 of the fifth coil row 05 of the second layer coil 200 first passes through the coil 1 of the fourth coil row 04 of the second layer coil 200, and then passes through the coil 1 of the second coil row 02 of the first layer coil 100.

[0141] The sixth coil row 06 of the second layer coil 200 is connected in series with the fifth coil row 05 of the second layer coil 200, and the sixth coil row 06 of the second layer coil 200 is connected in series with the first coil row 01 of the first layer coil 100. It can be understood that the coil 1 of the sixth coil row 06 of the second layer coil 200 first passes through the coil 1 of the fifth coil row 05 of the second layer coil 200, and then passes through the coil 1 of the first coil row 01 of the first layer coil 100.

[0142] From the above, it can be seen that the nth 1 The coil is arranged horizontally in the nth row of the first layer coil 100. 2 The coil rows correspond to each other; among them, the nth 1 Coil row and nth 2 The coils are connected in series, i.e. 1 At least one stitch 1 and the nth stitch of a row 2 At least one coil of a coil row is connected in series; n 1 and n 2 are all positive integers, and n 1 +n 2 =a+1, where a is the larger one of the number of rows of the second layer coil 200 and the number of rows of the first layer coil 100.

[0143] The wire material of the three-dimensional knitted fabric provided in the above embodiments can be wool, cotton, or silk used in the traditional knitting industry, or it can be reinforcing fiber materials such as glass fiber, carbon fiber, and wood fiber, which is not limited in the embodiments of the present application.

[0144] Based on the three-dimensional knitted fabric provided in the above embodiment, a three-dimensional knitted fabric of any shape can be formed. Assuming that the size of each coil 1 in the three-dimensional knitted fabric is basically the same, the three-dimensional knitted fabric of any shape corresponds to the change in the number of coil layers, the change in the number of coil rows in each layer of coils, and the change in the number of coils in each coil row. It can be understood that as the number of coils increases in the three directions of X, Y and Z, the volume of the three-dimensional knitted fabric can be expanded according to demand. It is a true three-dimensional solid knitted structure and can generate three-dimensional knitted fabrics of any shape.

[0145] The case where the number of coil layers increases will be described in detail below.

[0146] In some embodiments, the three-dimensional knitted fabric can be selected to include: at least three layers of coils 1, and any two layers of coils 1 are distributed in sequence along the thickness direction of the three-dimensional knitted fabric; wherein, among two adjacent layers of coils 1, at least one coil 1 of one is connected in series with at least one coil 1 of the other.

[0147] For example, the three-dimensional knitted fabric may include a first layer of coils, a second layer of coils, and a third layer of coils sequentially distributed in the Z direction.

[0148] It should be noted that, among the second layer coil and the third layer coil, the second layer coil can be called the lower layer coil, and the third layer coil can be called the upper layer coil; among the second layer coil and the first layer coil, the second layer coil can be called the upper layer coil, and the first layer coil can be called the lower layer coil.

[0149] For the first layer coil and the second layer coil, please refer to the above description and will not be repeated here.

[0150] The series relationship between the second layer coil and the first layer coil may be the same as or different from the series relationship between the third layer coil and the second layer coil.

[0151] The above-mentioned series connection relationship may include: the series connection position, and the number of coils connected in series. The same series connection relationship means that the series connection position is the same and the number of coils connected in series is the same. The different series connection relationship means that the series connection position is different and / or the number of coils connected in series is different.

[0152] Exemplarily, in the XYZ coordinate system, the horizontal coordinate and the vertical coordinate of at least one stringing position of the second layer coil and the first layer coil are the same as the horizontal coordinate and the vertical coordinate of at least one stringing position of the third layer coil and the second layer coil, that is, at least one stringing connection position is the same. In the XYZ coordinate system, the horizontal coordinate and the vertical coordinate of at least one stringing position of the second layer coil and the first layer coil are different from the horizontal coordinate and the vertical coordinate of at least one stringing position of the third layer coil and the second layer coil, that is, at least one stringing connection position is different.

[0153] It should be noted that the horizontal axis refers to the X-up position, and the vertical axis refers to the Y-up position.

[0154] The forming direction of the third layer coil can be the same as or opposite to that of the first layer coil, depending on the actual situation. In order to facilitate weaving, the forming direction of the second layer coil can be opposite to that of the first layer coil, and the forming direction of the third layer coil can be the same as that of the first layer coil, that is, the forming direction of the third layer coil is opposite to that of the second layer coil.

[0155] The three-dimensional knitted fabric may further include other layers of coils (e.g., a fourth layer of coils, a fifth layer of coils, a sixth layer of coils, etc.). The number of coil rows of the third layer of coils, the number of coils in each coil row of the third layer of coils, the number of coil rows of other layers of coils, and the number of coils in each coil row of other layers of coils are selected according to the shape of the three-dimensional knitted fabric actually required, and the embodiment of the present application does not limit this.

[0156] The following specifically describes the case where the number of stitch rows increases and decreases.

[0157] In actual situations, the number of rows of coils in any one layer may be increased, for example, the number of rows of coils in the first layer may be increased, and / or the number of rows of coils in the second layer may be increased, and / or the number of rows of coils in the third layer may be increased.

[0158] Accordingly, the number of coil rows of any one layer of coils may be reduced, for example, the number of coil rows of the first layer of coils may be reduced, and / or the number of coil rows of the second layer of coils may be reduced, and / or the number of coil rows of the third layer of coils may be reduced.

[0159] The following specifically describes the increase and decrease in the number of coils in one or some coil rows.

[0160] Fig.11 The method of increasing the number of stitches in certain rows is shown. Fig.11 As shown, the layer of coils includes four rows of coils, which are recorded as the first row of coils 01, the second row of coils 02, the third row of coils 03 and the fourth row of coils 04 from bottom to top. The first row of coils 01 and the second row of coils 02 each include three coils, and the third row of coils 03 and the fourth row of coils 04 each include four coils. Among them, the third coil of the second row of coils 02 and the third coil of the third row of coils 03 are not interlocked, and the third coil of the second row of coils 02 and the fourth coil of the third row of coils 03 are interlocked. Of course, it is also possible to choose that the fourth coil of the third row of coils and the third coil of the first row of coils are not interlocked, and the third coil of the first row of coils and the fourth coil of the fourth row of coils are interlocked.

[0161] The first row of coils woven may be referred to as the old row of coils, and the later row of coils woven may be referred to as the new row of coils. In the above structure, the new row of coils has one more coil than the old row of coils. Of course, it is also possible to select that the new row of coils has two or more coils than the old row of coils. Exemplarily, a layer of coils includes four rows of coils, which are recorded as the first row of coils, the second row of coils, the third row of coils, and the fourth row of coils from bottom to top. The first row of coils and the second row of coils each include three coils, and the third row of coils and the fourth row of coils each include five coils. In this case, it is possible to select that the first coil of the third row of coils and the first coil of the second row of coils are not interlocked, the second coil of the second row of coils and the third coil of the third row of coils are interlocked (the second coil of the third row of coils and the second coil of the second row of coils are not interlocked), and the third coil of the second row of coils and the fifth coil of the third row of coils are interlocked (the third coil of the second row of coils and the fourth coil of the third row of coils are not interlocked). Of course, the second coil in the second row of coils and the fourth coil in the third row of coils, or the third coil in the second row of coils and the fifth coil in the third row of coils may also be selected, which is not limited in the embodiment of the present application.

[0162] The above-mentioned method of increasing the number of coils is not limited to the case where adjacent coil rows are interlaced, but can also be applied to the case where non-adjacent coil rows are interlaced. Fig.11In the embodiment, the third stitch of the first stitch row 01 and the fourth stitch of the third stitch row 03 are not interlocked, and the third stitch of the first stitch row 01 and the fourth stitch of the fourth stitch row 04 are interlocked.

[0163] Fig.12 The method of reducing the number of stitches in certain rows is shown. Fig.12 As shown, the layer of coils includes four rows of coils, which are recorded as the first row of coils 01, the second row of coils 02, the third row of coils 03 and the fourth row of coils 04 from bottom to top. The first row of coils 01 and the second row of coils 02 each include four coils, and the third row of coils 03 and the fourth row of coils 04 each include three coils. Among them, the fourth coil of the first row of coils 01 and the third coil of the third row of coils 03 are connected in series, or the fourth coil of the first row of coils 01 and the third coil of the fourth row of coils 04 are connected in series.

[0164] In the above structure, the new coil row is one coil less than the old coil row. Of course, the new coil row can also be selected to be two or more coils less than the old coil row. For the specific stringing method, please refer to the previous text, which will not be repeated here.

[0165] The above-mentioned method of reducing the number of coils is not limited to the case where adjacent coil rows are interlaced, but can also be applied to the case where non-adjacent coil rows are interlaced. Fig.12 In the figure, the fourth stitch of the second row 01 and the third stitch of the third row 03 are not interlocked, and the fourth stitch of the second row 01 and the third stitch of the fourth row 04 are interlocked.

[0166] The three-dimensional knitted fabric provided in the embodiment of the present application can be knitted by hand or woven by a knitting machine, and the embodiment of the present application does not limit this.

[0167] The following describes a method for knitting a three-dimensional knitted fabric provided in an embodiment of the present application.

[0168] like Fig.13 As shown, the knitting method of the three-dimensional knitted fabric provided in the embodiment of the present application includes:

[0169] S11: weave the first layer of coils;

[0170] S12: In the thickness direction of the first layer of coils, weave a second layer of coils connected to the first layer of coils.

[0171] It should be noted that the first layer coil can be called a lower layer coil, and the second layer coil can be called an upper layer coil. The lower layer coil and the upper layer coil are two adjacent layers of coils.

[0172] In S11, the method for weaving the first layer of coils and the second layer of coils needs to be designed according to the structure of the first layer of coils. The first layer of coils and the second layer of coils can both be weft knitting structures, and the weft knitting structure can be a plain weft structure, a rib structure, a double reverse structure, or a double rib structure.

[0173] Taking the first layer coil and the second layer coil as an example, both are weft knitted structures, S11 and S12 are specifically described.

[0174] like Fig.14 As shown, S11: weaving the first layer of coils, specifically including:

[0175] S111: knitting the first row of stitches;

[0176] S112: knitting a second row of coils connected to the first row of coils;

[0177] S113: knitting a third row of coils connected to the second row of coils;

[0178] S114: knitting a fourth row of stitches connected to the third row of stitches;

[0179] S115: knitting a fifth row of stitches connected to the fourth row of stitches;

[0180] S116: Weaving a sixth row of coils connected to the fifth row of coils to form a first layer of coils.

[0181] like Figure 2 As shown, S111 specifically includes: weaving the wire into a plurality of coils 1 connected in the transverse direction to form a first coil row 01.

[0182] For the convenience of description, the transverse direction may be referred to as the X direction. The transverse direction may be the width direction of the three-dimensional knitted fabric.

[0183] The number of coils is selected according to actual conditions, and the present application embodiment does not limit this. Figure 2 As shown, there are six coils in the first coil row. Of course, the number of coils 1 in the first coil row 01 can also be one, two, three, four, five or more than seven, which is not limited in the present embodiment.

[0184] like Figure 3 and Figure 4 As shown, S112 specifically includes: at a longitudinal set position of the first coil row 01 , a coil is strung in each coil 1 of the first coil row 01 to form a second coil row 02 .

[0185] It should be noted that the first coil row 01 and the second coil row 02 are sequentially distributed along the longitudinal direction. For ease of description, the longitudinal direction can be recorded as the Y direction. The Y direction and the X direction are perpendicular to each other, or the X direction and the Y direction are inclined to each other; wherein, the angle between the X direction and the Y direction is selected according to actual conditions, and this embodiment does not limit this.

[0186] By analogy, S113 is specifically: at the longitudinal set position of the second coil row 02, one coil is strung in each coil 1 of the second coil row 02 to form the third coil row 03; S114 is specifically: at the longitudinal set position of the third coil row 03, one coil is strung in each coil 1 of the third coil row 03 to form the fourth coil row 04; S115 is specifically: at the longitudinal set position of the fourth coil row 04, one coil is strung in each coil 1 of the fourth coil row 04 to form the fifth coil row 05; S116 is specifically: one coil is strung in each coil 1 of the fifth coil row 05 to form the sixth coil row 06.

[0187] In S112, S113, S114, S115 and S116, the wires forming the old coil row can be turned at the ends to form new coil rows, or the wires forming the old coil row can be cut and newly added to form new coil rows. It should be noted that the coil row knitted first is the old coil row, and the coil row knitted later is the new coil row.

[0188] In other embodiments, the number of the coil rows of the first layer of coils may also be one, two, three, four, five or more than seven.

[0189] In S11, at least one coil of one of two adjacent coil rows may be interlaced with at least one coil of the other, and at least one coil of one of the two adjacent coil rows may be interlaced with a coil of the other coil row. In this way, a tuck structure may be formed in the first layer coil 100.

[0190] In the above S12, a second layer of coils connected to the first layer of coils are woven in the thickness direction of the first layer of coils.

[0191] It should be noted that the thickness direction of the first layer of coils is the thickness direction of the three-dimensional knitted fabric, and is also the thickness direction of each layer of coils of the three-dimensional knitted fabric. For ease of description, the thickness direction can be recorded as the Z direction. The Z direction is perpendicular to the plane formed by the X direction and the Y direction. Figure 7-Figure 10 As shown, the second layer coil 200 and the first layer coil 200 are connected in series in the Z direction.

[0192] like Fig.15As shown, the above S12: weaving a second layer of coils connected to the first layer of coils in a thickness direction of the first layer of coils, specifically includes:

[0193] S121: knitting the first row of the second layer of coils;

[0194] S122: knitting a first row of coils that are interlaced with the second layer of coils, and a second row of coils that are interlaced with the first row of coils that are interlaced with the first layer of coils;

[0195] S123: knitting a second row of coils that are interlaced with the second layer of coils, and a third row of coils that are interlaced with the second row of coils that are interlaced with the first layer of coils;

[0196] S124: knitting a third row of coils that are interlaced with the second layer of coils, and a fourth row of coils that are interlaced with the third row of coils of the first layer of coils;

[0197] S125: knitting a fourth row of coils that are interlaced with the second layer of coils, and a fifth row of coils that are interlaced with the fourth row of coils of the first layer of coils;

[0198] S126: knitting the fifth row of coils that are interlaced with the second layer of coils and the sixth row of coils that are interlaced with the fifth row of coils that are interlaced with the first layer of coils to form a second layer of coils.

[0199] In S121, S122, S123, S124, S125 and S126, the wires forming the old coil row may be turned at the ends to form new coil rows, or the wires forming the old coil row may be cut and newly added to form new coil rows. It should be noted that the coil row knitted first is the old coil row, and the coil row knitted later is the new coil row.

[0200] S121 specifically includes: forming the first coil row 01 of the second coil layer 200 at a set position directly above the first coil row 01 of the first coil layer 100. It can be understood that the coil 1 of the first coil row 01 of the first coil layer 100 and the coil 1 of the first coil row 01 of the second coil layer 200 are not connected in series.

[0201] It should be noted that, in the Z direction, the distance between the set position and the first coil row 01 of the first layer of coils 100 depends on the thickness of the wire and the size of the coils.

[0202] S122 specifically includes: passing the wire through the first coil of the first coil row 01 of the second layer coil 200, and then passing through the first coil of the first coil row 01 of the first layer coil 100, so as to form the first coil of the second coil row 02 of the second layer coil 200;

[0203] The wire is passed through the second coil of the first coil row 01 of the second layer coil 200 first, and then through the second coil of the first coil row 01 of the first layer coil 100, so as to form the second coil of the second coil row 02 of the second layer coil 200;

[0204] The wire is passed through the third coil of the first coil row 01 of the second layer coil 200 first, and then through the third coil of the first coil row 01 of the first layer coil 100, to form the third coil of the second coil row 02 of the second layer coil 200;

[0205] The wire is passed through the fourth coil of the first coil row 01 of the second layer coil 200, and then through the fourth coil of the first coil row 01 of the first layer coil 100, so as to form the fourth coil of the second coil row 02 of the second layer coil 200;

[0206] The wire is passed through the fifth coil of the first coil row 01 of the second layer coil 200, and then through the fifth coil of the first coil row 01 of the first layer coil 100, so as to form the fifth coil of the second coil row 02 of the second layer coil 200;

[0207] The wire is first passed through the sixth loop of the first row 01 of the second layer of coils 200, and then passed through the sixth loop of the first row 01 of the first layer of coils 100, to form the sixth loop of the second row 02 of the second layer of coils 200, thus completing the knitting of the second row 02.

[0208] It should be noted that in S122, after the wire passes through the coils of the first coil row 01 of the first coil layer 100, the coils of the first coil row 01 of the first coil layer 100 are changed from a flat state to a pulled-up state.

[0209] According to the above S122, by analogy, S123 is specifically: the wire material first passes through the first coil of the second coil row 02 of the second layer coil 200, and then passes through the first coil of the second coil row 02 of the first layer coil 100, to form the first coil of the third coil row 03 of the second layer coil 200, and so on to form other coils of the third coil row 03 of the second layer coil 200, and the knitting of the third coil row 03 can be completed; S124 is specifically: the wire material first passes through the first coil of the third coil row 03 of the second layer coil 200, and then passes through the first coil of the third coil row 03 of the first layer coil 100, to form the first coil of the fourth coil row 04 of the second layer coil 200, and so on to form other coils of the fourth coil row 04 of the second layer coil 200, and the fourth coil row 04 of the second layer coil 200 can be completed. S125 is specifically: the wire material first passes through the first coil of the fourth coil row 04 of the second layer coil 200, and then passes through the first coil of the fourth coil row 04 of the first layer coil 100, to form the first coil of the fifth coil row 05 of the second layer coil 200, and so on to form other coils of the fifth coil row 05 of the second layer coil 200, and the weaving of the fifth coil row 05 can be completed; S126 is specifically: the wire material first passes through the first coil of the fifth coil row 05 of the second layer coil 200, and then passes through the first coil of the third coil row 03 of the first layer coil 100, to form the first coil of the fourth coil row 04 of the second layer coil 200, and so on to form other coils of the sixth coil row 06 of the second layer coil 200, and the weaving of the sixth coil row 06 can be completed.

[0210] It can be seen from S121, S122, S123, S124, S125 and S126 that S12 specifically includes: weaving the n'+1th coil row of the second layer coil which is connected in series with the n'th coil row of the first layer coil 100; wherein n' is a positive integer, and n'+1 is not greater than the number of coil rows of the second layer coil 200 and not greater than the number of coil rows of the first layer coil 100.

[0211] It can be known from S121, S122, S123, S124, S125 and S126 that the nth coil row of the second layer coil 200 is knitted along the Y direction at the position where the nth coil row of the first layer coil 100 is located; wherein n is a positive integer, and n is not greater than the number of coil rows of the second layer coil 200 and not greater than the number of coil rows of the first layer coil 100.

[0212] In the above embodiment, the number of coil rows of the first coil layer 100 is the same as the number of coil rows of the second coil layer 200, the number of coils in any two coil rows in the first coil layer 100 is the same, the number of coils in any two coil rows in the second coil layer 200 is the same, and the number of coils in the coil rows in the first coil layer 100 is the same as the number of coils in the coil rows in the second coil layer 200.

[0213] In some other embodiments, the number of coil rows of the first layer coil 100 may be different from the number of coil rows of the second layer coil 200 , for example, the number of coil rows of the first layer coil 100 may be greater than or less than the number of coil rows of the second layer coil 200 .

[0214] In some other embodiments, the number of coils in the horizontal row of coils in the first layer of coils 100 is different from the number of coils in the horizontal row of coils in the second layer of coils 200. Exemplarily, the number of coils in the horizontal row of coils in the second layer of coils 200 and the number of coils in the horizontal row of coils in the first layer of coils 100, which are sequentially distributed along the Z direction, are different. In this case, it can be selected that some coils in the horizontal row of coils in the second layer of coils 200 are connected in series with the corresponding coils in the first layer of coils 100, and some coils in the second horizontal row of coils in the second layer of coils 200 are not connected in series with the coils in the first layer of coils 100.

[0215] In some other embodiments, at least two rows of coils in the first layer of coils 100 have different numbers of coils; and / or at least two rows of coils in the first layer of coils 100 have the same number of coils.

[0216] Correspondingly, the number of coils in at least two rows of coils in the second layer of coils 200 is different; and / or the number of coils in at least two rows of coils in the second layer of coils 200 is the same.

[0217] In the embodiment of the present application, each coil in the second row 02 of the second coil 200 is connected in series with the corresponding coil in the first coil 100. Of course, it is also possible to select that some coils in the second row 02 of the second coil 200 are connected in series with the corresponding coils in the first coil 100, and some coils in the second row 02 of the second coil 200 are not connected in series with the coils in the first coil 100. Exemplarily, in S122, it is possible to select that the wire material only passes through the fifth coil in the first row 01 of the second coil 200 to form the fifth coil in the second row 02 of the second coil 200. In this way, the fifth coil in the second row 02 of the second coil 200 is not connected in series with the coil in the first coil 100. Of course, it is also possible to select that other coils in the second row 02 of the second coil 200 are not connected in series with the coil in the first coil 100, which is not limited in the embodiment of the present application.

[0218] In the above embodiment, it can be seen from S11 and S12 that the forming direction of the second layer coil 200 (the distribution direction of the previous coil row and the next coil row) is the same as the forming direction of the first layer coil 100. Figure 7 and Figure 8 As shown. It can be understood that in the longitudinal direction of the coil row, the weaving direction of the second layer coil 200 is the forming direction of the second layer coil 200; in the longitudinal direction of the coil row, the weaving direction of the first layer coil 100 is the forming direction of the first layer coil 100. On this basis, in addition to the aforementioned stringing method (the n'+1th coil row of the second layer coil 200 is connected in series with the n'th coil row of the first layer coil 100), other stringing methods can also be selected. For example, S12 specifically includes weaving the nth coil row of the second layer coil connected in series with the nth coil row of the first layer coil 100; wherein n is a positive integer, and n is not greater than the number of coil rows of the second layer coil 200, and is not greater than the number of coil rows of the first layer coil 100.

[0219] On the basis that the forming direction of the second layer coil 200 is the same as that of the first layer coil 100, in addition to the knitting method mentioned above, it is also possible to knit the nth coil row of the second layer coil 200 in the longitudinal direction at a position offset from the nth coil row of the first layer coil 100; wherein n is a positive integer, which is not greater than the number of coil rows of the second layer coil 200 and not greater than the number of coil rows of the first layer coil 100.

[0220] In some embodiments, the above S121 may be specifically as follows: forming the first coil row 01 of the second layer coil 200 at a set position just above the second coil row 02 of the first layer coil 100. In this way, the first coil row 01 of the second layer coil 200 corresponds to the second coil row 02 of the first layer coil 100, that is, the first coil row 01 of the second layer coil 200 and the first coil row 01 of the first layer coil 100 are offset. By analogy, the second row 02 of the second layer of coils 200 corresponds to the third row 03 of the first layer of coils 100 (the second row 02 of the second layer of coils 200 and the second row 02 of the first layer of coils 100 are offset), the third row 03 of the second layer of coils 200 corresponds to the fourth row 04 of the first layer of coils 100 (the third row 03 of the second layer of coils 200 and the third row 03 of the first layer of coils 100 are offset), the fourth row 04 of the second layer of coils 200 corresponds to the fifth row 05 of the first layer of coils 100. The fourth row 04 of the second layer coil 200 corresponds to the fourth row 04 of the first layer coil 100 (the fourth row 04 of the second layer coil 200 is misaligned with the fourth row 04 of the first layer coil 100), the fifth row 05 of the second layer coil 200 corresponds to the sixth row 06 of the first layer coil 100 (the fifth row 05 of the second layer coil 200 is misaligned with the fifth row 05 of the first layer coil 100), and the sixth row 06 of the second layer coil 200 extends relative to the first layer coil 100 (the sixth row 06 of the second layer coil 200 is misaligned with the sixth row 06 of the first layer coil 100). By analogy, the specific steps of S122, S123, S124, S125 and S126 can be adaptively adjusted with reference to the above S12, which will not be described in detail here.

[0221] In the above S121, it can be selected that the coil 1 of the first coil row 01 of the second layer coil 200 and the coil 1 of the first coil row 01 of the first layer coil 100 are not connected in series, or the coil 1 of the first coil row 01 of the second layer coil 200 and the coil 1 of the first coil row 01 of the first layer coil 100 are connected in series.

[0222] If the coil 1 of the first coil row 01 of the second layer coil 200 is connected in series with the coil 1 of the second coil row 02 of the first layer coil 100, the above S121 is specifically as follows: the wire is passed through the first coil of the first coil row 01 of the first layer coil 100 to form the first coil of the first coil row 01 of the second layer coil 200; the wire is passed through the second coil of the first coil row 01 of the first layer coil 100 to form the second coil of the first coil row 01 of the second layer coil 200; and so on, other coils of the first coil row 01 of the second layer coil 200 are formed, and the knitting of the second coil row 02 can be completed.

[0223] In some other embodiments, S121 may be specifically selected as: forming the first coil row 01 of the second layer coil 200 at a set position directly above the third coil row 03, the fourth coil row 04, the fifth coil row 05 or the sixth coil row 06 of the first layer coil 100.

[0224] Correspondingly, the second coil row 02, the third coil row 03, the fourth coil row 04, the fifth coil row 05 and the sixth coil row 06 of the second layer coil 200 are sequentially moved along with the first coil row 01 of the second layer coil 200, and S122, S123, S124, S125 and S126 are adjusted accordingly, which will not be described in detail herein.

[0225] like Fig. 9 and Fig.10 As shown, the forming direction of the second layer coil 200 can also be selected to be opposite to the forming direction of the first layer coil 100. In this case, in the knitting method of the three-dimensional braided fabric provided by the embodiment of the present application, S121 is specifically: passing the wire through the first coil of the sixth coil row 06 of the first layer coil 100 to form the first coil of the first coil row 01 of the second layer coil 200; passing the wire through the second coil of the sixth coil row 06 of the first layer coil 100 to form the second coil of the first coil row 01 of the second layer coil 200; and so on, forming other coils of the first coil row 01 of the second layer coil 200, that is, completing the knitting of the first coil row 01 of the second layer coil 200.

[0226] S122 specifically includes: passing the wire through the first coil of the first coil row 01 of the second coil 200, and then passing through the first coil of the fifth coil row 05 of the first coil 100, to form the first coil of the second coil row 02 of the second coil 200; passing the wire through the second coil of the first coil row 01 of the second coil 200, and then passing through the second coil of the fifth coil row 05 of the first coil 100, to form the second coil of the second coil row 02 of the second coil 200; passing the wire through the third coil of the first coil row 01 of the second coil 200, and then passing through the third coil of the fifth coil row 05 of the first coil 100, to form the third coil of the second coil row 02 of the second coil 200; and so on, forming other coils of the second coil row 02 of the second coil 200, that is, completing the knitting of the second coil row 02 of the second coil 200.

[0227] It should be noted that, in S121, after the wire passes through the coil of the sixth coil row 06 of the first layer coil 100, the coil of the sixth coil row 06 of the first layer coil 100 changes from a flat state to a pulled-up state. In S122, after the wire passes through the coil of the fifth coil row 05 of the first layer coil 100, the coil of the fifth coil row 05 of the first layer coil 100 changes from a flat state to a pulled-up state.

[0228] According to the above S121 and S122, and so on, the specific steps of S123, S124, S125 and S126 can be adjusted accordingly according to S122, and the knitting of the third coil row 03, the fourth coil row 04, the fifth coil row 05 and the sixth coil row 06 of the second layer of coils 200 can be completed, thereby completing the knitting of the second layer of coils 200.

[0229] From the above S121, S122, S123, S124, S125 and S126, it can be known that S12 specifically includes: in the nth layer of the first layer coil 100 2 The nth knitting of the second layer of coils 200 is performed at the corresponding position of the coil row. 1 Coil row; among them, the nth 1 Coil row and nth 2 The coils are connected in series, i.e. 1 At least one stitch of the row and the nth stitch 2 At least one coil of a coil row is connected in series; n 1 and n 2 are all positive integers, and n 1 +n 2 =a+1, where a is the larger one of the number of rows of the second layer coil 200 and the number of rows of the first layer coil 100.

[0230] In the weaving method of the three-dimensional knitted fabric provided in the above embodiment, a three-dimensional knitted fabric with a solid structure can be obtained by stringing the second layer coils 200 and the first layer coils 100 sequentially distributed in the thickness direction, and the three-dimensional knitted fabric is extended in the thickness direction.

[0231] In the weaving method of the three-dimensional knitted fabric provided in the above embodiment, the material of the wire used can be wool, cotton, or silk thread used in the traditional knitting industry, or it can be reinforcing fiber materials such as glass fiber, carbon fiber, wood fiber, etc., which is not limited in the embodiments of the present application.

[0232] In the weaving method of the three-dimensional knitted fabric provided in the above embodiment, whether there is a loop between two adjacent coils in the Y direction and the Z direction can be adjusted according to needs, thereby adjusting the connection strength of different parts inside the three-dimensional knitted fabric to obtain a three-dimensional knitted fabric with different physical (mechanical) properties, which can meet the needs of different industries and scenarios.

[0233] Based on the knitting method of the three-dimensional knitted fabric provided in the above embodiment, a three-dimensional knitted fabric of any shape can be formed. Assuming that the size of each coil in the three-dimensional knitted fabric is basically the same, the three-dimensional knitted fabric of any shape corresponds to the change in the number of coil layers, the change in the number of coil rows in each layer of coils, and the change in the number of coils in each coil row. It can be understood that as the number of coils increases in the three directions of X, Y and Z, the volume of the three-dimensional knitted fabric can be expanded according to demand. It is a true three-dimensional solid knitted structure and can generate three-dimensional knitted fabrics of any shape.

[0234] The case where the number of coil layers increases will be described in detail below.

[0235] In some embodiments, when the number of coil layers of the required three-dimensional knitted fabric is three or more, a corresponding number of coil layers are added based on the above-mentioned three-dimensional knitted fabric knitting method.

[0236] Exemplarily, the knitting method of the three-dimensional knitted fabric includes:

[0237] S11: weave the first layer of coils;

[0238] S12: weaving a second layer of coils connected to the first layer of coils in a thickness direction of the first layer of coils;

[0239] S13: in the thickness direction of the second layer of coils, weaving a third layer of coils connected to the second layer of coils.

[0240] It should be noted that the thickness direction of the first layer coil is the thickness direction of the second layer coil and also the thickness direction of the third layer coil. In the third layer coil and the second layer coil, the second layer coil can be called the lower layer coil, and the third layer coil can be called the upper layer coil; in the second layer coil and the first layer coil, the second layer coil can be called the upper layer coil, and the first layer coil can be called the lower layer coil.

[0241] For S11 and S12, reference may be made to the foregoing text, and for the specific weaving method of S13, reference may be made to the foregoing S12.

[0242] In the embodiment of the present application, the series relationship between the second layer coil and the first layer coil and the series relationship between the third layer coil and the second layer coil may be the same or different, and the specific content can be referred to the above.

[0243] The forming direction of the third layer coil can be the same as or opposite to that of the first layer coil, depending on the actual situation. In order to facilitate weaving, the forming direction of the second layer coil can be opposite to that of the first layer coil, and the forming direction of the third layer coil can be the same as that of the first layer coil, that is, the forming direction of the third layer coil is opposite to that of the second layer coil. It can be understood that the forming directions of the two adjacent layers of coils are opposite.

[0244] When the knitting method of the three-dimensional knitted fabric further includes knitting other layers of coils (eg, a fourth layer of coils, a fifth layer of coils, a sixth layer of coils, etc.), refer to S13, which will not be described in detail herein.

[0245] The number of coil rows of the third layer of coils, the number of coils in each coil row of the third layer of coils, the number of coil rows of other layers of coils, and the number of coils in each coil row of other layers of coils are selected according to the shape of the three-dimensional knitted fabric actually required, and the embodiments of the present application do not limit this.

[0246] The following specifically describes the case where the number of stitch rows increases and decreases.

[0247] In actual situations, at least one row of knitting of any layer of coils may be increased. For example, at least one row of knitting of the first layer of coils may be increased, and / or at least one row of knitting of the second layer of coils may be increased, and / or at least one row of knitting of the third layer of coils may be increased.

[0248] Accordingly, the knitting of at least one row of coils of any layer may be reduced. For example, the knitting of at least one row of coils of the first layer may be reduced, and / or the knitting of at least one row of coils of the second layer may be reduced, and / or the knitting of at least one row of coils of the third layer may be reduced.

[0249] The following specifically describes the method of increasing and decreasing the number of coils in one or some coil rows.

[0250] Fig.11 The method of increasing the number of stitches in certain rows is shown. Fig.11As shown, the layer of coils includes four coil rows, which are recorded as a first coil row 01, a second coil row 02, a third coil row 03 and a fourth coil row 04 from bottom to top. The first coil row 01 and the second coil row 02 each include three coils, and the third coil row 03 and the fourth coil row 04 each include four coils. The first row of stitches 01 is knitted by S111 mentioned above, and the second row of stitches 02 is knitted by S112 mentioned above. When knitting the third row of stitches 03 from left to right, the wire passes through the first stitch of the second row of stitches 02 to form a loop, forming the first stitch of the third row of stitches 03; then the wire passes through the second stitch of the second row of stitches 02 to form a loop, forming the second stitch of the third row of stitches 03; then the wire directly forms a loop to form the third stitch of the third row of stitches 03; then the wire passes through the third stitch of the second row of stitches 02 to form a loop, forming the fourth stitch of the third row of stitches 03, completing the knitting of the third row of stitches 03. Due to the volume and force of the stitches themselves, the third stitch of the second row of stitches 02 will be squeezed to the right. Then the fourth row of stitches 03 is knitted by S114 mentioned above.

[0251] In the above method, the third stitch of the second stitch row 02 and the third stitch of the third stitch row 03 are not interlaced.

[0252] The first row of coils knitted may be referred to as the old row of coils, and the later row of coils knitted may be referred to as the new row of coils. The above method is not limited to the case where the new row of coils has one more coil than the old row of coils, and may also be applied to the case where the new row of coils has two or more coils than the old row of coils. Exemplarily, a layer of coils includes four rows of coils, which are recorded as the first row of coils, the second row of coils, the third row of coils, and the fourth row of coils from bottom to top. The first row of coils and the second row of coils each include three coils, and the third row of coils and the fourth row of coils each include five coils. In this case, it may be selected that the first coil of the third row of coils and the first coil of the second row of coils are not interlocked, the second coil of the second row of coils and the third coil of the third row of coils are interlocked (the second coil of the third row of coils and the second coil of the second row of coils are not interlocked), and the third coil of the second row of coils and the fifth coil of the third row of coils are interlocked (the third coil of the second row of coils and the fourth coil of the third row of coils are not interlocked). Of course, the second coil in the second row of coils and the fourth coil in the third row of coils, or the third coil in the second row of coils and the fifth coil in the third row of coils may also be selected, which is not limited in the embodiment of the present application.

[0253] The above method is not limited to the case where adjacent coil rows are interlocked, but can also be applied to the case where non-adjacent coil rows are interlocked. Fig.11In the embodiment, the third stitch of the first stitch row 01 and the fourth stitch of the third stitch row 03 are not interlocked, and the third stitch of the first stitch row 01 and the fourth stitch of the fourth stitch row 04 are interlocked.

[0254] Fig.12 The method of reducing the number of stitches in certain rows is shown. Fig.12 As shown, the layer of coils includes four coil rows, which are recorded as a first coil row 01, a second coil row 02, a third coil row 03 and a fourth coil row 04 from bottom to top. The first coil row 01 and the second coil row 02 each include four coils, and the third coil row 03 and the fourth coil row 04 each include three coils. The first row 01 is knitted using the aforementioned S111, and the second row 02 is knitted using the aforementioned S112. When knitting the third row 03 from left to right, the wire passes through the first coil of the second row 02 to form a loop, forming the first coil of the third row 03; then the wire passes through the second coil of the second row 02 to form a loop, forming the second coil of the third row 03; then the wire passes through the third coil of the second row 02, and then passes through the fourth coil of the second row 02 to form a loop, forming the third coil of the third row 03, completing the knitting of the third row 03. Due to the force on the coil, the fourth coil of the second row 02 will be pulled to the left. Then the fourth row 03 is knitted using the aforementioned S114.
