The second knitting row forms a part of the bottom layer, and turns the c yarn at the corresponding needle positions on the front needle bed to the needle positions on the back needle bed for needle turning knitting;

[0113] The c yarn at the corresponding needle positions on the back needle bed is offset 1 needle position to the left to form empty needle positions, and then turns the needles to the needle positions on the front needle bed for needle turning knitting;

[0114] S42. The knitting head of the knitting device moves rightward, while driving the yarn guides A and B to knit;

[0115] The yarn guide A knits the first knitting row through the front needle bed with a one-stitch-one-empty-stitch alternate knitting method. The first knitting row forms a part of the surface layer, and turns the c yarn at the corresponding needle positions on the back needle bed to the needle positions on the front needle bed for needle turning knitting; the yarn guide B knits the second knitting row through the back needle bed with a one-stitch-one-empty-stitch alternate knitting method, and turns the c yarn at the corresponding needle positions on the front needle bed to the needle positions on the back needle bed for needle turning knitting;

[0116] S43. Repeat S41 - S42 at least once. When repeating, the left and right edges of the needle turning knitting and the needle shifting knitting are reduced by 2 needle positions inward compared with the previous time.

[0117] The above knitting method will be elaborated in detail with two embodiments below.

[0118] Embodiment 1: Refer to Figure 1 and Figure 2

[0119] Yarn a is a transparent monofilament for the surface, yarn b is a high-elastic polyester for the bottom layer, and yarn c is a high-elastic polyester for the support layer.

[0120] Taking 16 knitting rows as a cycle unit, the knitting method of 16 knitting rows is as follows:

[0121] In the 1st knitting row, yarn a is knitted on the front needle bed in the way of knitting one stitch and leaving one stitch empty to form the surface layer (i.e., surface knitting).

[0122] In the 2nd knitting row, yarn b is knitted on the back needle bed in the way of knitting one stitch and leaving one stitch empty to form the bottom layer (i.e., bottom knitting).

[0123] The 3rd to 8th knitting rows are the repeated knitting of the 1st to 2nd knitting rows.

[0124] From the 1st to 8th knitting rows, yarn a is knitted on the front needle bed to form the surface layer and yarn b is knitted on the back needle bed to form the bottom layer.

[0125] In the 9th knitting row, yarn c is knitted on the back needle bed in the way of knitting with dropped stitches and knitting every other stitch of the bottom knitting, and the needle position is offset by 1 needle position from that of yarn a and yarn b.

[0126] From the 10th to 14th knitting rows, yarn c is knitted on the back needle bed in the way of knitting one stitch and leaving one stitch empty.

[0127] In the 15th and 16th knitting rows, the bottom layer coils at the corresponding needle positions are moved 1 needle position to the left, and then the needles are turned over to form the surface layer coils for the needle movement knitting.

[0128] From the 9th to 16th knitting rows, yarn c forms a three-dimensional support layer.

[0129] For all the knitting actions of the 1st to 16th knitting rows, from the 17th to 32nd knitting rows are the repeated knitting of the 1st to 16th knitting rows. Repeating the above cycle method can knit the entire fabric body.

[0130] After the fabric knitting is completed, it also needs to go through high-temperature treatment. For the fabric without using heat-melt filaments, the high-temperature treatment is to make the fabric shrink sufficiently when heated to achieve a suitable fabric effect; for the fabric using heat-melt filaments, it needs to go through high-temperature treatment to melt the heat-melt filaments and bond them inside the fabric to achieve a suitable fabric effect; finally, on the fabric body, jacquard areas with the color of the bottom layer can be seen on the surface layer, making the entire fabric body have jacquard areas with different colors from the surface layer, and applying it to the shoe upper is more beautiful.

[0131] Example 2: Refer to Figure 3 and Figure 4

[0132] Yarn a is a transparent monofilament for the surface, yarn b is a high-elastic polyester for the bottom layer, and yarn c is a high-elastic polyester for the support layer.

[0133] The first knitting row is to knit the a yarn on the front needle bed in a way of knitting one stitch and leaving one stitch empty, which is used to form the surface layer (i.e., surface knitting).

[0134] The second knitting row is to knit the b yarn on the back needle bed in a way of knitting one stitch and leaving one stitch empty, which is used to form the bottom layer (i.e., bottom knitting).

[0135] The third knitting row is to knit the c yarn on the back needle bed in an alternate stitch knitting method with bottom knitting, and the needle position is offset by 1 needle position from the a yarn and the b yarn.

[0136] The fourth to eighth knitting rows are to knit the c yarn on the back needle bed in a way of knitting one stitch and leaving one stitch empty.

[0137] The ninth knitting row is to knit the a yarn on the front needle bed in a way of knitting one stitch and leaving one stitch empty.

[0138] The tenth and eleventh knitting rows are purl knitting by turning the c yarn loops at the corresponding back needle bed positions to the front needle bed.

[0139] The twelfth knitting row is to knit the b yarn on the back needle bed in a way of knitting one stitch and leaving one stitch empty.

[0140] The thirteenth and fourteenth knitting rows are purl knitting by turning the c yarn loops at the corresponding front needle bed positions to the back needle bed.

[0141] The fifteenth and sixteenth knitting rows are purl knitting by moving the c yarn loops at the corresponding back needle bed positions 1 needle position to the left and then turning them to the front needle bed.

[0142] The seventeenth knitting row is to knit the a yarn on the front needle bed in a way of knitting one stitch and leaving one stitch empty.

[0143] The eighteenth and nineteenth knitting rows are purl knitting by turning the c yarn loops at the corresponding back needle bed positions to the front needle bed.

[0144] The twentieth knitting row is to knit the b yarn on the back needle bed in a way of knitting one stitch and leaving one stitch empty.

[0145] The twenty - first and twenty - second knitting rows are purl knitting by turning the c yarn surface loops at the corresponding front needle bed positions to the back needle bed.

[0146] The twenty - third and twenty - fourth knitting rows are purl knitting by moving the c yarn bottom loops at the corresponding back needle bed positions 1 needle position to the left and then turning them to the front needle bed.

[0147] The twenty - fifth knitting row is to knit the a yarn on the front needle bed in a way of knitting one stitch and leaving one stitch empty.

[0148] The twenty - sixth and twenty - seventh knitting rows are purl knitting by turning the c yarn loops at the corresponding back needle bed positions to the front needle bed.

[0149] The twenty - eighth knitting row is to knit the b yarn on the back needle bed in a way of knitting one stitch and leaving one stitch empty.

[0150] In the 29th and 30th knitting rows, the c-yarn surface coils corresponding to the needle positions on the front needle bed are turned over to the back needle bed for purl knitting.

[0151] In the 31st and 32nd knitting rows, the c-yarn bottom coils corresponding to the needle positions on the back needle bed are moved 1 needle position to the left and then turned over to the front needle bed for purl knitting.

[0152] Compared with the 10th - 11th knitting rows, the 18th - 19th knitting rows, and the 21st - 24th knitting rows, the purl and transfer knitting on the left and right edges are each reduced inward by 2 needle positions; the purl and transfer knitting on the left and right edges of the 26th - 27th knitting rows and the 29th - 32nd knitting rows are each reduced inward by 4 needle positions, forming a wavy support layer.

[0153] After the fabric knitting is completed, it also needs to go through high-temperature treatment. For fabrics without using heat-melt yarn, the high-temperature treatment is to make the fabric shrink sufficiently when heated to achieve a proper fabric effect; for fabrics using heat-melt yarn, it needs to go through high-temperature treatment to melt the heat-melt yarn and bond it inside the fabric to achieve a proper fabric effect; finally, on the fabric body, a jacquard area with the bottom color shown on the surface layer can be seen, making the entire fabric body have a jacquard area with a different color from the surface layer, which is more beautiful when applied to the shoe upper.

[0154] In the above embodiments, the knitting yarn can also be polyamide, spandex, and acrylic, and the fabric structure can also be porous and jacquard. The fabric with a three-dimensional decorative structure containing independent or continuous structures in the above embodiments is used to make a shoe upper, which reduces the use of adhesives for making a shoe upper with a three-dimensional structure by gluing, reduces pollution, and is more environmentally friendly.
