[0065] The above-mentioned knitting method will be described in detail in the following three embodiments.

[0066] Embodiment one: refer to Figure 1 and Figure 2

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

[0068] The first row of stitches is knitted in the full needle manner by the a yarn, which is used to form the face layer (i.e. face knitting).

[0069] The second row of stitches is knitted in the full needle manner by the b yarn, which is used to form the bottom layer (i.e. bottom knitting).

[0070] The third row of stitches is face knitting by the a yarn, and part of the needle positions are bottom knitting.

[0071] The fourth row of stitches is bottom knitting by the b yarn, and the corresponding face needle positions of the third row of stitches are face knitting.

[0072] The fifth row of stitches is face knitting by the a yarn.

[0073] The sixth row of stitches is bottom knitting by the b yarn.

[0074] The seventh row of stitches is face knitting by the a yarn.

[0075] The eighth row of stitches is bottom knitting by the b yarn.

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

[0077] The 10th row is a bottom knitting of the b yarn, and the corresponding face needle positions of the 9th row bottom knitting needle positions are face knitting.

[0078] The 11th row is a face knitting of the a yarn.

[0079] The 12th row is a bottom knitting of the b yarn.

[0080] All knitting actions of the 1st to 6th rows are consistent with all knitting actions of the 7th to 12th rows, and the knitting positions are staggered by two needle positions, so that the fabric surface is more flat and the knitting organization is uniform.

[0081] After the fabric is knitted, it needs to be treated at high temperature. For the fabric without using hot melt yarn, the high temperature treatment is to make the fabric fully shrink after being heated, so as to achieve the appropriate fabric effect. For the fabric using hot melt yarn, it needs to be treated at high temperature to make the hot melt yarn melt and adhere to the inside of the fabric, so as to achieve the appropriate fabric effect. Finally, the jacquard area with the color of the bottom layer can be seen on the surface layer of the fabric body, so that the entire fabric body has a jacquard area different from the color of the surface layer, which is more beautiful when applied to the upper of the shoe.

[0082] Example two: refer to Figure 3 and Figure 4

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

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

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

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

[0087] The 4th row is bottom knitting of the b yarn, and the corresponding face needle positions of the 3rd row bottom knitting needle positions are four flat knitting.

[0088] The 5th row is face knitting of the a yarn.

[0089] The 6th row is bottom knitting of the b yarn.

[0090] The 7th row is face knitting of the a yarn.

[0091] The 8th row is bottom knitting of the b yarn.

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

[0093] The 10th row is b yarn for ground knitting, and four plain knitting is done at the corresponding face needle position of the 9th row.

[0094] The 11th row is a yarn for face knitting.

[0095] The 12th row is b yarn for ground knitting.

[0096] The four plain knitting can make the jacquard area small by adjusting the density of the original face layer.

[0097] The knitting actions of the 1st to 6th rows are consistent with those of the 7th to 12th rows, and the knitting positions are staggered by two needle positions. In order to make the knitting structure uniform and the fabric surface flat, the above cycle is repeated to knit the entire fabric body.

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

[0099] The difference between this embodiment and Embodiment One is that the size of the jacquard area is different.

[0100] The 1st row is a yarn for full needle knitting, which is used to form a face layer (i.e., face knitting).

[0101] The 2nd row is b yarn for full needle knitting, which is used to form a ground layer (i.e., ground knitting).

[0102] The 3rd row is a yarn for face knitting, and part of the needle positions are for ground knitting.

[0103] The 4th row is b yarn for ground knitting, and the face knitting is done at the corresponding face needle position of the 3rd row.

[0104] The 5th row is the repeated knitting of the 3rd row.

[0105] The 6th row is b yarn for ground knitting, and the face loop knitting is done at the face knitting needle position of the 4th row.

[0106] The 7th row is a yarn for face knitting.

[0107] The 8th row is b yarn for ground knitting.

[0108] The 9th row is a yarn for face knitting, and part of the needle positions are for ground knitting.

[0109] The 10th row is b yarn for ground knitting, and the face knitting is done at the corresponding face needle position of the 3rd row.

[0110] The 11th row is the repeated knitting of the 3rd row.

[0111] The 12th row is b yarn for ground knitting, and the face loop knitting is done at the face knitting needle position of the 4th row.

[0112] The knitted loops are pulled apart to become large loops.

[0113] All the knitting actions of the first to sixth rows are consistent with all the knitting actions of the seventh to twelfth rows, and the knitting positions are staggered by two needle positions, so as to make the knitting structure uniform and the fabric surface flat. The above cycle is repeated to knit the whole fabric body.
