Abstract
Description
Technical Field
[0001] The invention relates to a knitting method of fabric, in particular to a knitting method of warp-lined knitted fabric. Background Art
[0002] Knitted fabrics are woven using a knitting process. This allows for direct conversion from yarn to finished fabric, eliminating the need for subsequent cutting and sewing. These fabrics are widely used in the uppers of various sports shoes. To enhance the aesthetics of sports shoe uppers, interlining warp weaves are introduced into knitted fabrics, creating interlining warp knitted fabrics.
[0003] The warp yarns of the existing interlining knitted fabrics are usually sandwiched into the fabric body in a straight line, and the warp yarns are arranged along the warp direction of the fabric body and perpendicular to the weft yarns. It is difficult to weave complex texture shapes, resulting in a relatively small texture design space for the shoe upper. This is because when using traditional weaving technology, if the warp yarns of the interlining tissue are moved along the weft direction, it is easy for the warp yarns to be woven together with the weft yarns, resulting in the warp yarns forming staggered or broken lines on the surface of the fabric body.
[0004] In view of this, the inventors conducted in-depth research on the knitting method of the interlining warp knitted fabric, and thus the present invention was produced. Summary of the Invention
[0005] The object of the present invention is to provide a knitting method for a warp-lined knitted fabric which has a large texture design space and is less likely to have staggered or broken sections.

[0007] As an improvement of the present invention, during weaving, the A yarn and the C yarn sandwich and fix the B yarn.
[0008] As an improvement of the present invention, after the B yarn is tucked and before the yarn is cast off, a needle pressing action is performed.
[0009] As an improvement of the present invention, when the B yarn is knitted into tuck loops, the yarn mouth for introducing the B yarn moves upward.
[0010] A method for knitting a warp-lined knitted fabric, comprising knitting the knitted fabric using at least three yarns, wherein the three yarns are respectively A yarn, B yarn, and C yarn; the A yarn and the C yarn are woven to form a fabric body; the B yarn is a warp yarn that is inserted into the fabric body and does not participate in loop formation; a yarn mouth for introducing the B yarn is located between a yarn mouth for introducing the A yarn and a yarn mouth for introducing the C yarn; the B yarn is arranged non-parallel to the warp direction of the fabric body, or a local position of the B yarn is arranged non-parallel to the warp direction of the fabric body; When weaving a position where the B yarn is not parallel to the warp direction of the fabric body, the B yarn is first tucked, then an empty needle action is performed, and the yarn mouth for introducing the B yarn is moved to a non-current weaving area, and then the yarn mouth for introducing the B yarn is moved back to the current weaving area when the A yarn and the C yarn are weaving.

[0013] As an improvement of the present invention, the B yarn and the D yarn are arranged parallel to each other.
[0014] As an improvement of the present invention, there is a crossing point between the B yarn and the D yarn.
[0015] As an improvement of the present invention, the A yarn is a polyester high-strength yarn, the B yarn is a polyester high-elastic spandex double-covered yarn, and the C yarn is a TPU yarn.
[0016] By adopting the above technical solution, the present invention has the following beneficial effects: The weaving method adopted by the present invention, through specific weaving actions, enables the warp yarn to avoid the needle exit of the looping needle hook corresponding to the weft yarn during the process of moving in the weft direction toward the fabric body, and it is less likely that the warp yarn will be woven together with the weft yarn.

DETAILED DESCRIPTION
[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that the terms "first" and "second" in the present invention are used to distinguish different objects rather than to describe a specific order.
[0019] Example 1 This embodiment provides a method for knitting a warp-lined knitted fabric, wherein the knitted fabric is knitted using three yarns, namely yarn A, yarn B, and yarn C. Of course, more than three yarns may also be used. Preferably, yarn A is a high-strength polyester yarn, yarn B is a high-elasticity polyester spandex double-covered yarn, and yarn C is a TPU yarn. The high-strength polyester yarn, high-elasticity polyester spandex double-covered yarn, and TPU yarn are all conventional yarns that can be purchased directly from the market. They are not the focus of this embodiment and will not be described in detail here.
[0020] Figure 1 The following is a warp knitted fabric obtained by the knitting method of this embodiment, as shown in FIG. Figure 1As shown, yarn A and yarn C are woven to form a fabric body 10, i.e., yarns A and C are the main yarns, and yarn B is the warp yarn 20 that is inserted into the fabric body 10 and does not participate in loop formation. Yarn B is arranged non-parallel to the warp direction of the fabric body. Of course, it is also possible to arrange only a local position (i.e., a local segment) of yarn B non-parallel to the warp direction of the fabric body. It should be noted that in various embodiments of the present invention, the longitudinal direction of the fabric body is the warp direction, which is perpendicular to the width direction of the fabric body, and the row direction of the fabric body is the weft direction, which is consistent with the width direction of the fabric body.
[0021] During the weaving process, yarn A and yarn C are introduced through the same yarn mouth, that is, the weaving paths of yarn A and yarn C are the same, and the yarn mouth for introducing yarn B is located between the yarn mouth for introducing yarn A and the yarn mouth for introducing yarn C, that is, yarn A and yarn C are located in front and behind yarn B respectively, so that yarn B can be clamped and fixed by yarn A and yarn C. The specific clamping structure is as follows: Figure 2 As shown, yarn A is located at the bottom layer, yarn B as warp yarn 20 is located on yarn A, and yarn C is located at the surface layer, so that yarn A and yarn C can sandwich and fix yarn B. It should be noted that Figure 2 It is only for the purpose of illustrating the sandwich structure. The positions of the A yarn and the C yarn can also be interchanged. In addition, Figure 2 The purpose of yarn A being thicker than yarn C is to illustrate the positions of the two yarns, and does not represent the actual thickness of the yarn.
[0022] When weaving a position where the B yarn is not parallel to the warp direction of the fabric body, the B yarn is first tucked in, and the yarn mouth for introducing the B yarn is moved up, and then the needle pressing action is performed to adjust the size of the B yarn loop. Then, when the A yarn and the C yarn are weaving, the tucked loop of the B yarn is removed from the corresponding knitting needle to achieve undoing. Finally, the B yarn is moved in the weft direction for a predetermined number of needles, and the above actions are repeated until the weaving of the corresponding position is completed. In this way, the warp yarn position can be fixed by tucked in, and when the main yarn is woven out of the needle, the warp yarn tucked loop is naturally undoed from the needle hook, so that the warp yarn avoids the needle of the weft yarn loop hook when it changes direction, ensuring that the warp yarn is straight and there will be no staggered or broken knots.
[0023] like Figure 3 As shown, the specific knitting steps of this embodiment are as follows: The first knitting row is a dense bottom knitting of yarns A and C.
[0024] The second weaving row is a tight tuck weaving with yarn B, i.e. Figure 3 The knitting action of the 8th knitting column of the 2nd knitting row is that the tight tuck knitting is a common tuck knitting, which will not be described in detail here; the 3rd knitting row is the B yarn doing the needle pressing action, that is, Figure 3The knitting action of the 8th weaving column of the 3rd weaving row is used to adjust the size of the B yarn loop; the 4th weaving row is a dense stitch bottom weaving of the A and C yarns. During this weaving process, the tuck loop of the 3rd weaving row will fall off the corresponding knitting needle. Specifically, since the tuck loop is woven with warp yarn, one side of it is clamped in the fabric of the needle bed, and the other side is located at the yarn outlet of the corresponding yarn mouth. There is a certain distance from the needle bed to the yarn outlet of the yarn mouth. The yarn hanging hole located at this distance has a certain inclination angle relative to the horizontal plane. The corresponding knitting needle hook is hung within this distance to make the tuck loop. When the weft yarn is woven to the needle position corresponding to the tuck loop, the knitting needle moves forward, and the warp yarn will fall off the needle hook under the action of tension.
[0025] The 5th weaving row is the tight tuck weaving of yarn B, and the 6th weaving row is the pressing action of yarn B. The positions of the weaving actions of these two weaving rows are offset by 2 needle positions to the left compared to the positions of the weaving actions of the 2nd and 3rd weaving rows, so that yarn B moves in the weft direction, forming a warp yarn arranged non-parallel to the warp direction on the fabric body.
[0026] Knitting continues with the knitting movements of the 4th, 5th, and 6th rows as a loop, with the position of each loop shifted two needle positions to the left of the position of the previous loop. That is, the knitting movements of the 7th, 8th, and 9th rows are identical to the knitting movements of the 4th, 5th, and 6th rows, respectively, but the positions of the knitting movements of the 7th, 8th, and 9th rows correspond to the knitting movements of the 4th, 5th, or 6th rows, shifted two needle positions to the left. The knitting movements of the 10th, 11th, and 12th rows are identical to the knitting movements of the 7th, 8th, and 9th rows, respectively, but the positions of the knitting movements of the 10th, 11th, and 12th rows correspond to the knitting movements of the 7th, 8th, and 9th rows, respectively, shifted two needle positions to the left of the positions of the knitting movements of the 7th, 8th, or 9th rows.
[0027] Starting from the 13th weaving row, the above cycle continues, but the offset position is opposite, that is, the 16th to 18th weaving row, the 19th to 21st weaving row, and the 22nd to 24th weaving row are all offset 2 needle positions to the right compared with the previous cycle, so that the warp yarn forms a fold angle on the fabric body.
[0028] Example 2 This embodiment provides a method for knitting a warp-lined knitted fabric, wherein the knitted fabric is knitted using four yarns, wherein the four yarns are yarn A, yarn B, yarn C, and yarn D. Of course, three or five or more yarns may also be used for knitting. Preferably, yarn A is a high-strength polyester yarn, yarns B and D are both high-elasticity polyester spandex double-covered yarns, and yarn C is a TPU yarn. The high-strength polyester yarn, high-elasticity polyester spandex double-covered yarn, and TPU yarn are all conventional yarns that can be purchased directly from the market. They are not the focus of this embodiment and will not be described in detail here.
[0029] Figure 4 The following is a warp knitted fabric obtained by the knitting method of this embodiment, as shown in FIG. Figure 3 As shown, the fabric body 10 is woven from yarns A and C. Yarns A and C are the main yarns, while yarns B 21 and D 22 are warp yarns inserted into the fabric body 10 and do not participate in loop formation. Yarns B 21 and D 22 are arranged non-parallel to the warp direction of the fabric body. Alternatively, only local locations (i.e., local segments) of yarns B 21 and / or D 22 may be arranged non-parallel to the warp direction of the fabric body. Furthermore, yarns B 21 and D 22 may be arranged parallel to each other or crosswise on the fabric body, i.e., with a cross point between yarns B 21 and D 22. In this embodiment, yarns B 21 and D 22 may be arranged parallel to each other.
[0030] During the weaving process, yarn A and yarn C are led out through the same yarn mouth, that is, the weaving paths of yarn A and yarn C are consistent, and the yarn mouth for introducing yarn B and the yarn mouth for introducing yarn D are both located between the yarn mouth for introducing yarn A and the yarn mouth for introducing yarn C, that is, yarn A and yarn C are located in front and back positions of yarn B and yarn D respectively, so that yarn B and yarn D can be clamped and fixed by yarn A and yarn C. When weaving the position where yarn B is not parallel to the warp direction of the fabric body, yarn B is first tucked in, and then the empty needle action is performed, and the yarn mouth for introducing yarn B is moved to the non-current weaving area, for example, it can be moved to the woven area. The above action can also be called empty needle kicking yarn mouth. Then, when yarn A and yarn C are weaving, the yarn mouth for introducing yarn B is moved back to the current weaving area of yarn B. Finally, yarn B moves a predetermined number of needles in the weft direction, and the above action is repeated until the weaving of the corresponding position is completed. In this way, when the warp yarn is weaving in a loop, the warp yarn can be kicked out of the loop by the empty needle to avoid the needle hook of the weft yarn loop. After the weft yarn loop is woven, the yarn mouth of the warp yarn is kicked back to the warp yarn weaving position so that it can continue to move with the weaving action, so as to ensure that the warp yarn will not be caught by the needle hook of the weft yarn weaving needle when it moves in the weft direction, and there will be no misalignment or breakage. Therefore, a fabric with a unique structure, good elasticity and three-dimensional sense can be woven during the warp and weft weaving process.
[0031] Similarly, when weaving a position where the D yarn is not arranged parallel to the warp direction of the fabric body, the D yarn is first tucked, then the empty needle action is performed, and the yarn mouth for introducing the D yarn is moved to the non-current weaving area. Then, when the A yarn and the C yarn are weaving, the yarn mouth for introducing the D yarn is moved back to the current weaving area of the D yarn. Finally, the D yarn is moved in the weft direction for a predetermined number of needles, and the above actions are repeated until the weaving of the corresponding position is completed.
[0032] like Figure 5 As shown, the specific knitting steps of this embodiment are as follows: The first knitting row is a dense bottom knitting of yarns A and C.
[0033] The second weaving row is the bottom tight tuck weaving of yarn B, that is Figure 5 The knitting action of the third knitting column of the second knitting row in the knitting process is shown in Figure 2. The third knitting row is the empty needle action of yarn B, so as to adjust the position of the yarn feeder for introducing yarn B. Specifically, when knitting, the yarn feeder for introducing yarn B moves first, and the knitting needle at the corresponding position eats the thread later. There is a certain distance between the yarn feeder and the knitting needle. The empty needle row is to allow the yarn feeder that moves in advance to return to the top of the knitting needle, so that the yarn feeder stops accurately and will not be looped by yarn A or yarn C.
[0034] The 4th weaving row is the bottom tight tuck weaving of D yarn, that is Figure 5 The knitting action of the 14th knitting column of the 4th knitting row in the knitting process is shown in Figure 2; the 5th knitting row is the empty needle action for D yarn, so as to adjust the position of the yarn feeder for introducing D yarn. Specifically, when knitting, the yarn feeder for introducing D yarn moves first, and the knitting needle at the corresponding position eats the thread later. There is a certain distance between the yarn feeder and the knitting needle. The empty needle row is to allow the yarn feeder that moves in advance to return to the top of the knitting needle, so that the yarn feeder stops accurately and will not be looped by the A yarn or C yarn.
[0035] The 6th knitting row is a dense base knitting with yarn A and yarn C.
[0036] The knitting action of the 2nd and 3rd rows is the first cycle action, and the knitting action of the 4th and 5th rows is the second cycle action. The first cycle action and the second cycle action are alternately performed to continue knitting. The position of each first cycle action is shifted to the right by 2 needle positions compared with the position of the previous first cycle action, and the position of each second cycle action is shifted to the left by 2 needle positions compared with the position of the previous second cycle action. That is, the knitting action of the 7th and 8th rows is consistent with the knitting action of the 2nd and 3rd rows, and the knitting position is shifted to the right by 2 needle positions. The 1st and 8th rows are the same as the knitting action of the 2nd and 3rd rows, and the knitting position is shifted to the right by 2 needle positions. The 2nd and 13th rows, the 17th and 18th rows, the 22nd and 23rd rows, and the 27th and 28th rows all move to the right according to this rule. The 9th and 10th rows have the same weaving action as the 4th and 5th rows, and the weaving position moves 2 needle positions to the left. The 14th and 15th rows, the 19th and 20th rows, the 24th and 25th rows, and the 29th and 30th rows all move to the left according to this rule. In this way, through the weaving of the 12th to 25th rows, the two groups of warp yarns overlap and cross each other.
[0037] Example 3 The embodiment provides a method for weaving a warp-lined knitted fabric, which is basically the same as that of embodiment 2, with the main difference being that the texture of the warp-lined structure obtained by weaving is different.
[0038] Figure 6 The following is a warp knitted fabric obtained by the knitting method of this embodiment, as shown in FIG. Figure 3As shown, the A yarn and the C yarn are woven to obtain the fabric body 10, that is, the A yarn and the C yarn are the main yarns, the B yarn 21 and the D yarn 22 are the warp yarns that are inserted into the fabric body 10 and do not participate in the loop formation, and the B yarn 21 and the D yarn 22 have a crossing point on the fabric body 10.

There is a certain distance between the yarn feeder and the knitting needle. The empty needle row is to allow the yarn feeder that moved in advance to return to the top of the knitting needle.
[0042] In order to adjust the position of the yarn mouth for introducing yarn B, the yarn mouth stops accurately and will not be looped by yarn A or yarn C.

In the 14th knitting row, yarns A and C encounter the D yarn stop point, and the yarn feeder that introduced the D yarn is kicked to the knitted area to avoid knitting under stitches. When knitting, the yarn feeder that introduced the D yarn moves first, and the knitting needles then pick up the thread. There is a certain distance between the two. The empty needle row is to allow the yarn feeder that moved in advance to return to the top of the knitting needles.
