[0004] The technical solution adopted by the present invention to solve its technical problem is:

[0005] A jacquard-needle free-plush knitted fabric comprises a surface layer, a plush layer and a bottom layer. A plush layer of any shape is arranged at any position of the surface layer or / and the bottom layer. The plush layers at different positions are connected or independent of each other. The plush layers at different positions have the same or different thicknesses. Gas flows between the surface layer and the bottom layer through a breathable structure.

[0006] A preferred technical solution: the breathable structure is a breathable hole.

[0007] A preferred technical solution: an intermediate layer is provided between the surface layer and the bottom layer, and the plush layer is extended and connected to the intermediate layer.

[0008] A preferred technical solution: the plush layer is combined on the surface layer to form a pattern.

[0009] A better technical solution: a jacquard layer is also woven on the surface layer.

[0010] A preferred technical solution: The thickness of the plush layer is adjusted by changing the thickness of the yarn.

[0011] A preferred technical solution: The thickness of the plush layer is adjusted by changing the needle method.

[0012] A better technical solution: The thickness of the plush layer is adjusted by changing the number of cross-needles.

[0013] A better technical solution: the plush layer creel jacquard forms a partial single / double layer or a partial plush layer by changing the needle method.

[0014] A better technical solution: the density of the plush layer is adjusted by changing the needle method / CAD design.

[0015] A method for preparing a jacquard-needle free-plush knitted fabric, comprising:

[0016] Guide bar setting: double needle bed jacquard warp knitting machine with groove needles is used for weaving;

[0031] Example 1

[0032] like Figure 1 , 3 As shown in , 4, the present embodiment provides a jacquard groove needle free plush knitted fabric, including a surface layer 1, a plush layer 2, and a bottom layer 3. The plush layer 2 of any shape is arranged at any position of the surface layer 1 or the bottom layer 3, the plush layers 2 at different positions are connected or independent of each other, the plush layers 2 at different positions are of consistent or inconsistent thickness, and gas is circulated between the surface layer 1 and the bottom layer 3 through a breathable structure.

[0033] Furthermore, the ventilation structure is ventilation holes 4 .

[0034] Furthermore, the plush layer 2 is combined on the surface layer 1 to form a pattern.

[0035] Furthermore, a jacquard layer 5 is woven on the surface layer 1 .

[0036] Furthermore, the thickness of the plush layer 2 can be adjusted by changing the thickness of the yarn.

[0037] Furthermore, the thickness of the plush layer 2 is adjusted by changing the needle method.

[0038] Furthermore, the thickness of the plush layer 2 is adjusted by changing the number of cross-needles.

[0039] Example 2

[0040] like Figure 2 As shown, this embodiment provides a jacquard groove needle free plush knitted fabric. The difference between this embodiment and embodiment 1 is that a plush layer 2 of any shape is arranged at any position of the surface layer 1 and the bottom layer 3, and an intermediate layer 6 is also arranged between the surface layer 1 and the bottom layer 3, and the plush layer 2 extends and connects to the intermediate layer 6.

[0041] The plush layer 2 on the free plush knitted fabric in Example 1 is arranged on the surface layer 1 or the bottom layer 3. Taking the free plush knitted fabric as an example, the plush layer 2 on the surface layer 1 is used for decoration or external warmth preservation; the plush layer 2 on the bottom layer 3 is used for internal warmth preservation and to increase the supporting thickness, such as knitting a plush layer 2 of a certain thickness in the shoe opening area of ​​the shoe upper, so that the warmth preservation effect after the foot is worn to the shoe opening is better;

[0042] The plush layer 2 on the free plush knitted fabric in Example 2 can be set on the surface layer 1 and the bottom layer 3 at the same time, which is equivalent to the cooperation between the inner layer and the outer layer. It is thick where the upper should be thick, and thinner where the upper has higher requirements for air permeability.

[0043] Example 3

[0044] This embodiment provides a method for preparing a jacquard-needle free-plush knitted fabric, comprising:

[0045] Guide bar setting: double needle bed jacquard warp knitting machine with groove needles is used for weaving;

[0046] Comb threading: The warped yarn is placed on the jacquard comb and ground comb according to the weaving process for threading;

[0047] Mesh cloth weaving: Use half-gauge jacquard bars to weave on the front needle bed to form a base layer consisting of a surface layer 1 and a bottom layer 3; use half-gauge jacquard bars to alternately weave between the front needle bed and the rear needle bed to form a plush layer 2 on the front needle bed or the rear needle bed, or form a partial single / double layer or a partial plush layer.

[0048] Furthermore, the thickness of the plush layer 2 on the surface layer 1 varies. A half-gauge jacquard bar is used to alternately weave between the front needle bed and the rear needle bed to form a first plush area with a thickness of A in the plush layer 2 of the front needle bed or the rear needle bed. A half-gauge jacquard bar is used to alternately weave between the front needle bed and the rear needle bed to form a second plush area with a thickness of B in the plush layer 2 of the front needle bed or the rear needle bed, wherein A is not equal to B.

[0049] A separate needle body structure is set on the groove needle. Unlike the latch needle, which will cause the needle to be closed after raising the hair, and once the needle is closed, it cannot be opened again, the groove needle can solve this problem; when the groove needle is knitted on the double needle bed jacquard warp knitting machine, it can freely raise and knit up and down, thereby realizing the free setting of the plush layer 2 at any position of the knitted fabric.
