Therefore, the gradient effect produced shows an unsmooth serrated shape; or the gradient effect needs to be printed through post-process, but such a process is complicated, time-consuming, and has a high production cost. Moreover, a large amount of chemical reagents are used in the printing process, which not only affects the hand feeling but also is not conducive to environmental protection.

[0003] In view of this, the inventor of this case has conducted in-depth research on the above problems, and thus this case has been created. Summary of the Utility Model

[0056] S21. The yarn feeder A knits the third knitting row through the front needle bed to form a part of the surface layer, and at least one needle position on the third knitting row makes a second coil knitting to form a part of the bottom layer;

[0057] S22. The yarn feeder B knits the fourth knitting row through the rear needle bed to form a part of the bottom layer, and the needle positions corresponding to the second coil knitting on the fourth knitting row make a first coil knitting to form a part of the surface layer;

[0064] After adopting the knitting method of the present utility model, the jacquard area can be changed according to design requirements, increasing the freedom of upper design and providing new ideas and directions for the design of jacquard points.

[0065] The following elaborates on the above knitting method with three embodiments.

[0066] Embodiment 1: Refer to Figure 1 and Figure 2

[0067] Taking 6 knitting rows as a cycle unit, the knitting method of 6 knitting rows is as follows:

[0068] For the 1st knitting row, yarn a is knitted in full needles to form the surface layer (i.e., surface knitting).

[0069] For the 2nd knitting row, yarn b is knitted in full needles to form the bottom layer (i.e., bottom knitting).

[0070] For the 3rd knitting row, yarn a is used for surface knitting, and partial needle positions are used for bottom knitting.

[0071] For the 4th knitting row, yarn b is used for bottom knitting, and surface knitting is carried out at the surface needle positions corresponding to the bottom knitting needle positions in the 3rd knitting row.

[0072] For the 5th knitting row, yarn a is used for surface knitting.

[0073] For the 6th knitting row, yarn b is used for bottom knitting.

[0074] For the 7th knitting row, yarn a is used for surface knitting.

[0075] For the 8th knitting row, yarn b is used for bottom knitting.

[0076] The 9th knitting row is knitted with yarn a on the surface, and part of the needle positions are knitted on the bottom.

[0077] The 10th knitting row is knitted with yarn b on the bottom, and the corresponding surface needle positions of the bottom knitting needle positions in the 9th knitting row are knitted on the surface.

[0078] The 11th knitting row is knitted with yarn a on the surface.

[0079] The 12th knitting row is knitted with yarn b on the bottom.

[0080] All the knitting actions in the 1st to 6th knitting rows are the same as those in the 7th to 12th knitting rows, and the knitting positions are staggered by two needle positions. In order to make the knitted structure evenly distributed and the fabric surface smoother; repeating the above knitting cycle can knit the entire fabric body.

[0081] After the fabric is knitted, it still 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 suitable 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 suitable fabric effect; finally, on the fabric body, a jacquard area with the color of the bottom layer 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.

[0082] Example 2: Refer to Figure 3 and Figure 4

[0083] The difference between this embodiment and Embodiment 1 is that the size of the jacquard area is different.

[0084] The 1st knitting row is full-needle knitting with yarn a, used to form the surface layer (i.e., surface knitting).

[0085] The 2nd knitting row is full-needle knitting with yarn b, used to form the bottom layer (i.e., bottom knitting).

[0086] The 3rd knitting row is knitted with yarn a on the surface, and part of the needle positions are knitted on the bottom.

[0087] The 4th knitting row is knitted with yarn b on the bottom, and full-purl knitting is done at the corresponding surface needle positions of the bottom knitting needle positions in the 3rd knitting row.

[0088] The 5th knitting row is knitted with yarn a on the surface.

[0089] The 6th knitting row is knitted with yarn b on the bottom.

[0090] The 7th knitting row is knitted with yarn a on the surface.

[0091] The 8th knitting row is knitted with yarn b on the bottom.

[0092] The 9th knitting row is knitted with yarn a on the surface, and part of the needle positions are knitted on the bottom.

[0093] For the 10th knitting row, the b yarn is used for bottom knitting, and full purl knitting is performed at the face needle positions corresponding to the bottom knitting needle positions in the 9th knitting row.

[0094] For the 11th knitting row, the a yarn is used for face knitting.

[0095] For the 12th knitting row, the b yarn is used for bottom knitting.

[0096] By adjusting the density of the original surface layer tightly in full purl knitting, the jacquard area can be made very small.

[0097] All the knitting actions in the 1st to 6th knitting rows are the same as those in the 7th to 12th knitting rows, and the knitting positions are staggered by two needle positions to make the distribution of the knitted structure uniform and the fabric surface smoother. Repeating the above knitting cycle can knit the entire fabric body.

[0098] Example 3: Refer to Figure 5 and Figure 6

[0099] The difference between this embodiment and Embodiment 1 lies in the size of the jacquard area.

[0100] For the 1st knitting row, the a yarn is knitted with full needles to form the surface layer (i.e., face knitting).

[0101] For the 2nd knitting row, the b yarn is knitted with full needles to form the bottom layer (i.e., bottom knitting).

[0102] For the 3rd knitting row, the a yarn is used for face knitting, and bottom knitting is performed at some needle positions.

[0103] For the 4th knitting row, the b yarn is used for bottom knitting, and face knitting is performed at the face needle positions corresponding to the bottom knitting needle positions in the 3rd knitting row.

[0104] For the 5th knitting row, it is a repeated knitting of the 3rd knitting row.

[0105] For the 6th knitting row, the b yarn is used for bottom knitting, and face drop stitch knitting is performed at the face knitting needle positions in the 4th knitting row.

[0106] For the 7th knitting row, the a yarn is used for face knitting.

[0107] For the 8th knitting row, the b yarn is used for bottom knitting.

[0108] For the 9th knitting row, the a yarn is used for face knitting, and bottom knitting is performed at some needle positions.

[0109] For the 10th knitting row, the b yarn is used for bottom knitting, and face knitting is performed at the face needle positions corresponding to the bottom knitting needle positions in the 3rd knitting row.

[0110] For the 11th knitting row, it is a repeated knitting of the 3rd knitting row.

[0111] For the 12th knitting row, the b yarn is used for bottom knitting, and face drop stitch knitting is performed at the face knitting needle positions in the 4th knitting row.

[0112] The hanging-eye knitting enlarges the original surface knitting loops into large loops.

[0113] All the knitting actions of the 1st to 6th knitting rows are the same as those of the 7th to 12th knitting rows, and the knitting positions are staggered by two needle positions to make the distribution of the knitted structure uniform and the fabric surface smoother. Repeating the above knitting cycle can knit the entire fabric body.
