Description

Technical Field

[0001] The utility model relates to the technical field of fabrics, in particular to a free-style single-layer and double-layer combined knitted fabric. Background Art

[0002] With the development of sports fabrics, light, thin and strong are the important development trends of textile sports in the future. However, although the full-layer fabrics are light and thin, they are seriously insufficient in strength, and the single-layer mesh fabrics also lose the sandwich Q elastic properties of mesh fabric applications. People in the mesh textile industry have also done various researches on this;

[0003] Method 1: Currently, the market uses a combination of single and double layers in a disc-shaped style, which has great limitations. It can only be in the vertical and horizontal directions, and the position is fixed, which greatly limits the design of the fabric. Secondly, the combination of single and double layers in a disc-shaped style, although it can achieve light weight and partial sandwich elasticity, increases the difficulty of workshop operation, increases labor costs, has a long production cycle, and seriously wastes time. It has innovations in design structure, but it is not enough.

[0004] Method 2: Use DTY (polyester) yarn to run in the middle of the creel, eat the yarn in some parts and not eat the yarn in other parts to achieve local thickness. The appearance is similar to single-layer or double-layer mesh cloth. However, the middle of the double-layer sandwich position is DTY yarn, and the single-layer part is just hollowed out in the middle and does not reach the true single-layer mesh cloth. The fabric needs to be touched to feel its thickness, and the visual effect of the physical structure is not achieved. The fabric post-processing is prone to abnormal bubbles, which affects the shoemaking effect and production. Utility Model Content

[0039] Example 1

[0040] like Figure 1 As shown, a free-style single- and double-layer knitted fabric comprises a surface layer 1, a bottom layer 3, a connecting layer 2, a bottom single layer 5 and / or a surface single layer 4. The surface layer 1 is connected to the bottom layer 3 through the connecting layer 2 to form a double-layer structure. The yarns constituting the surface layer 1, the bottom layer 3 and the connecting layer 2 are only woven together on the surface layer 1 to form the surface single layer 4. The yarns constituting the surface layer 1, the bottom layer 3 and the connecting layer 2 are only woven together on the bottom layer 3 to form the bottom single layer 5. The double-layer structure, the surface single layer 4 and / or the bottom single layer 5 are located on the same piece of knitted fabric and constitute a complete knitted fabric structure. The surface single layer 4 and / or the bottom single layer 5 are located in any local area of ​​the knitted fabric. The surface layer 1 and the bottom layer 3 form a double-layer structure, and the connecting layer 2 plays a connecting role. The knitted fabric is woven by a knitting device, on which a knitting needle 100 is arranged. The knitting needle 100 includes a needle core 102, a needle hook 101, and a needle belly. The needle core 102 is separately arranged on the needle belly, that is, a separate knitting needle. The knitting needle 100 is provided with a needle hook 101, and the needle belly specifically refers to the middle section of the entire knitting needle.

[0041] For example, a double-layer structure consisting of a surface layer 1, a bottom layer 3, and a connecting layer 2 is arranged on a piece of knitted fabric, and a single-layer 1 is also arranged, or a bottom layer 1 is also arranged, or a single-layer 1 and a bottom layer 1 are also arranged. The single-layer 1 and the bottom layer 1 are arranged at any position of the entire knitted fabric and can be woven to form a pattern of any shape.

[0042] The specific structure of the knitting needle 100 is shown in FIG. Figure 4 The knitting needle 100 structure in the prior art refers to Figure 5 The knitted fabric in this application will not be unable to continue knitting due to the machine being unable to start up due to closed needles, and can be woven directly using monofilament or thermoplastic yarn, thereby retaining the Q-elastic effect of the original traditional Sanming and achieving light weight (because monofilament and thermoplastic yarn are lighter than DTY yarn and have Q-elasticity), achieving a win-win situation.

[0043] Furthermore, a jacquard structure, that is, a jacquard pattern, is provided on the surface layer 1 and / or the bottom layer 3, so that the pattern on the surface of the knitted fabric is more diversified.

[0044] Furthermore, ventilation holes 11 are arranged on the surface layer 1 and / or the bottom layer 3. The ventilation holes 11 of any shape are arranged on the surface layer 1 and the bottom layer 3. The shapes of the ventilation holes 11 are, for example, circular, triangular, rectangular, etc.

[0045] Furthermore, the double-layer structure changes the local thickness of the knitted fabric by weaving a connecting layer 2 with different structures or containing different numbers of yarns.

[0046] By setting the above further structure, a knitted fabric structure with a corresponding structure is selected and combined.

[0047] Example 2

[0048] like Figure 2 , 3 As shown, this embodiment provides a free-style single-layer and double-layer knitted fabric. The structural difference between this embodiment and the free-style single-layer and double-layer knitted fabric in Implementation 1 is that:

[0049] The knitted fabric also includes a hollow structure 12 , and the double-layer structure is formed by delamination to form a hollow and unconnected hollow structure 12 between the surface layer 1 and the bottom layer 3 .

[0050] The surface layer 1, the connecting layer 2, and the bottom layer 3 are knitted with yarns of at least one color or at least one material. The surface layer 1, the connecting layer 2, and the bottom layer 3 can be knitted with single-color yarns to form a corresponding fabric structure, or can be knitted with multi-color yarns to form a corresponding fabric structure; the surface layer 1, the connecting layer 2, and the bottom layer 3 can be knitted with yarns of one material to form a corresponding fabric structure, or can be knitted with a combination of yarns of multiple materials to form a corresponding fabric structure. The more complex the fabric structure, the more jacquards are needed, and the jacquard pattern is improved by using more needles (two needles, three needles, four needles).

[0051] For example, when the connection layer 2 is made of a single material, the connection layer 2 is a connection layer 2 structure of a single material or a single color through single jacquard weaving;

[0052] For another example, if the connecting layer 2 has two structures, the connecting layer 2 is woven respectively by two jacquards (jacquard 1 21 and jacquard 2 2 in the figure), and the connecting layers 2 of the two structures can also be in two colors; or more jacquards can be used to achieve more style structures. In principle, by using more jacquards, the weaving equipment can weave a more complex structure.

[0056] The bottom single layer 5 is woven, and the bottom single layer 5 is woven continuously after the double-layer structure is woven. After the yarns constituting the surface layer 1, the connecting layer 2, and the bottom layer 3 are woven in a double-layer structure, the bottom single layer 5 is woven continuously at the bottom layer 3 position to form the bottom single layer 5;

[0057] After the bottom single layer 5 is knitted, choose to continue knitting the double layer structure.

[0101] The three-jacquard design can achieve a 3-color or 4-color jacquard on the mesh, or enrich the middle layer's wool height.

[0102] In the prior art, when preparing single-layer and double-layer fabrics, the fabrics can only be fixed by threading the yarn, in the vertical direction or changing the horizontal direction of the layout, which puts forward certain requirements on the machine operation during weaving, increases the time of manual operation, and the fabric structure is relatively limited, and can only be vertical or horizontal. For example, a single-layer structure in a rectangular shape (limited by vertical and horizontal) is set on the fabric, and the purpose of adjusting the width of the double layer and the single layer is achieved by controlling the amount of threading, and the machine can only be in the warp direction;

[0103] Compared with the prior art, the single-layer and double-layer fabrics in the present invention can be set to a non-rectangular (not restricted by vertical or horizontal) single-layer structure, such as a circular or a pattern composed of any weaving direction;

[0104] Knitting equipment usually operates in an open needle groove composed of upper and lower needle bed plates and upper and lower needle plates. The yarn is first fed into the needle groove through a yarn feeder, and the needle guide picks up the yarn and hangs it on the needle. As the needle bed moves back and forth, various patterns are knitted on the needle plate. Among them, the knitting needle 100 includes a needle core 102, a needle hook 101, and a needle belly. The needle core 102 is separately arranged on the needle belly, and is not subject to the problem of the machine being unable to start due to a closed needle.

[0105] Taking method 2 in the background technology as an example, it uses the method of not eating yarn in the middle to reduce the thickness of the double-layer fabric, and defines this thinned double layer as a single layer, but in fact it is still a double layer, and this part of the double layer is still separated. If you poke this part with your hand, the two layers can be staggered. The whole piece of fabric is double-layered, even if some parts are very thin and thought to be a single layer, in fact it still has a surface layer 1 and a bottom layer 3. It cannot be a single layer in the true sense (only the surface layer 1 is woven, not the bottom layer 3; or only the bottom layer 3 is woven, not the surface layer 1).

[0106] The needle core 102 of the traditional knitting needle 100 is closed. When the knitting equipment uses this knitting needle 100 to knit, after knitting the double-layer area and then the single-layer area, the knitting needle 100 will be closed. Once closed, it cannot be opened, and thus the knitting of single-layer and double-layer fabrics cannot be continuously realized. The knitting principle of the knitting needle 100: When knitting, the knitting needle 100 pads the yarn in the needle hook 101. When the machine descends, the old coil that has been knitted forward is taken out and reset. The needle core 102 opens and closes repeatedly, and new coils and old coils are continuously formed to complete the knitting action.

[0107] When the traditional knitting needle 100 is knitting fabric, after the fabric is opened and closed, and the double-layer structure is opened and closed, when knitting a single side, if one side is not knitted, the needle core 102 may be in two states: fully open or fully closed. Once closed, it can never be opened again, because one side is not knitted and there is no yarn for padding.

[0108] In the present application, the knitting needle 100 adopts a separate structure, which does not rely on the cooperation between the old coil and the new coil to open the needle core 102, and no longer relies on padding yarn or no padding yarn to determine whether the needle core 102 is open or not. The opening and closing of the needle core 102 is achieved by actively controlling the device.

[0109] Based on the above content, the single layer of the freestyle single- and double-layer combined knitted fabric in this application is a true single layer, and the "single layer" is not achieved by changing the thickness of the double-layer structure. At the same time, the weaving direction is not limited to horizontal or vertical, so that more styles and patterns can be woven, and the styles of the knitted fabric are more diverse.

[0110] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of implementation of the present invention. That is, equivalent changes and modifications made according to the patent scope of the present invention and the contents of the specification should still fall within the scope covered by the present invention.
