Description

Technical Field

[0001] This utility model relates to the field of woven fabrics, specifically to a warp-knitted sandwich mesh fabric that saves yarn. Background Technology

[0002] In fabric weaving, when the woven product (such as a shoe upper) is small, multiple patterns are usually laid out on a whole piece of fabric, and then cut to obtain multiple individual shoe uppers. This method creates scraps and waste. To save yarn, some manufacturers reduce the amount of yarn fed in the connecting areas of the shoe upper that need to be cut (e.g., only feeding the yarn for a single layer of fabric for weaving, while not feeding the yarn for other layers), thus creating thinner areas.

[0003] While it saves yarn, the selvage of single-layer fabric is too thin, making it prone to breakage during subsequent dyeing and setting processes. Furthermore, because the setting equipment relies on needle punching on both sides for fixation, the thin selvage is easily deformed under stress, leading to inaccurate setting, insufficient tension and strength support, and thus causing serious quality abnormalities. In practice, this results in defective products and further waste. Utility Model Content

[0004] To address the aforementioned problems, this invention provides a warp-knitted sandwich mesh fabric that saves yarn.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows: A yarn-saving warp-knitted sandwich mesh fabric has a connected product area and a connecting area, each of which has a top layer, an intermediate layer and a bottom layer, the intermediate layer connecting the top layer and / or the bottom layer; and at least one of the top layer, intermediate layer and bottom layer constituting the connecting area has a perforated structure.

[0006] Furthermore, the number of the hole structures is multiple.

[0007] Furthermore, the perforated structures formed on the same layer are arranged in a grid pattern to form a mesh structure.

[0008] Furthermore, the product area is the shoe upper area.

[0009] Furthermore, multiple product areas are arranged on the mesh fabric, and these product areas are connected by connecting areas.

[0010] Furthermore, among the top layer, intermediate layer and bottom layer constituting the connecting area, at least two layers have a porous structure; and the porous structures of the two layers are staggered.

[0011] Furthermore, among the top layer, intermediate layer and bottom layer constituting the connecting area, at least two layers have a porous structure; and the porous structures of the two layers correspond to each other.

[0012] The technical solution provided by this utility model has the following beneficial effects: Both the product area and the connecting area have a top layer, a middle layer, and a bottom layer. That is, the connecting area that needs to be cut is the same as the product area. It is also woven from the yarn of the top layer, the middle layer, and the bottom layer to form a sandwich structure, which ensures the strength of the connecting area and is beneficial to the subsequent processing after weaving. At the same time, while ensuring strength, at least one of the top layer, middle layer, and bottom layer that make up the connecting area has a perforated structure. That is, by weaving, a fabric layer with a perforated structure is formed to effectively save yarn consumption. Attached Figure Description

[0014] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0015] In the description of this utility model, terms such as "upper", "lower", "left", "right", "front", and "rear" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0016] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0017] Example 1 Reference Figures 1 to 2 As shown, this embodiment provides a warp-knitted sandwich mesh fabric that saves yarn, having connected product areas 1 and connecting areas 2. In this embodiment, the product area 1 is the shoe upper area, that is, the woven product is the shoe upper. Of course, in other embodiments, it can also be other products. There are multiple product areas 1, which are arranged in an array on the mesh fabric, and the multiple product areas 1 are connected by the connecting areas 2.

[0018] Both product area 1 and connecting area 2 have a surface layer 11, a middle layer 12, and a bottom layer 13. That is, both product area 1 and connecting area 2 are woven from the yarns of the surface layer 11, the middle layer 12, and the bottom layer 13, resulting in a sandwich mesh fabric with a surface layer 11, a middle layer 12, and a bottom layer 13. The middle layer 12 is located between the surface layer 11 and the bottom layer 13. The middle layer 12 connects the surface layer 11 and / or the bottom layer 13. Specifically, the yarns of the middle layer 12 can be individually connected to the surface layer 11 or the bottom layer 13, or they can be connected to both simultaneously to form the corresponding sandwich mesh fabric structure. The specific weaving thickness and weaving method of each layer are designed according to actual conditions; this is existing technology and will not be detailed here.

[0019] Among the surface layer 11, intermediate layer 12 and bottom layer 13 constituting the connecting region 2, at least one layer has a perforated structure 3. In this embodiment, the surface layer 1 has a perforated structure 3 (defined as surface perforation 31), which is formed by weaving yarn from the surface layer 11; while the intermediate layer 12 and bottom layer 13 do not have perforated structures 3.

[0020] Using the above technical solution, both product area 1 and connecting area 2 have a surface layer 11, a middle layer 12, and a bottom layer 13. That is, the connecting area 2, which needs to be cut, is the same as product area 1, also woven from the yarns of the surface layer 11, the middle layer 12, and the bottom layer 13, forming a sandwich structure. This ensures the strength of the connecting area 2 and facilitates subsequent processing, such as dyeing and setting, maintaining sufficient strength without easily breaking. Simultaneously, while ensuring strength, the surface layer 1 constituting the connecting area 2 forms a perforated structure 3 through weaving, saving on the amount of yarn used in the surface layer 11 of the connecting area 2, thereby effectively reducing costs.

[0021] Specifically, the surface layer 11 of the connecting region 2 has multiple perforated structures 3, which are arranged in a grid pattern to form a mesh structure. That is, the surface layer 11 of the connecting region 2 is a mesh-like surface layer. In this way, the regular mesh structure effectively reduces the amount of yarn used while making it easier to weave and form.

[0022] Example 2 This embodiment provides a warp-knitted sandwich mesh fabric that saves yarn, which has a structure largely the same as that provided in Embodiment 1, except that: (Refer to...) Figure 3 As shown, in this embodiment, the intermediate layer 12 constituting the connecting region 2 has a perforated structure 3 (defined as intermediate layer perforation 32), while the surface layer 11 and the bottom layer 13 do not have perforated structures 3. That is, the intermediate layer 12 constituting the connecting region 2 forms a perforated structure 3 through weaving, which saves the amount of yarn used in the intermediate layer 12 of the connecting region 2, thereby effectively reducing costs.

[0023] Meanwhile, the intermediate layer 12 of the connecting region 2 has multiple hole structures 3, but the multiple hole structures 3 are arranged in an irregular manner.

[0024] The solution provided in this embodiment can effectively reduce the amount of yarn used while ensuring strength, thus achieving the goal of saving yarn.

[0025] Of course, in other embodiments, the hole structure 3 may be designed only in the bottom layer 13 of the connection area 2.

[0026] Example 3 This embodiment provides a warp-knitted sandwich mesh fabric that saves yarn, which has a structure largely the same as that provided in Embodiment 1, except that: (Refer to...) Figure 4As shown, at least two of the surface layer 11, intermediate layer 12 and bottom layer 13 constituting the connecting region 2 have a perforated structure; in this embodiment, the intermediate layer 12 and the bottom layer 13 of the connecting region 2 both have a perforated structure 3, and the perforated structure 3 of the bottom layer 13 is defined as the bottom layer perforation 33, wherein the perforated structure 3 of the intermediate layer 12 (i.e., intermediate layer perforation 32) and the perforated structure 3 of the bottom layer 13 (i.e., bottom layer perforation 33) are staggered.

[0027] In this way, while ensuring strength, the amount of yarn used can also be effectively reduced, thus achieving the goal of saving yarn.

[0028] Example 4 This embodiment provides a warp-knitted sandwich mesh fabric that saves yarn, which has a structure largely the same as that provided in Embodiment 1, except that: (Refer to...) Figure 5 As shown, in the top layer 11, middle layer 12, and bottom layer 13 constituting the connecting region 2, both the top layer 11 and the middle layer 12 of the connecting region 2 have a perforated structure 3. The perforated structure 3 of the top layer 11 (i.e., top layer perforation 31) corresponds to the perforated structure 3 of the middle layer 12 (i.e., middle layer perforation 32). In this way, while ensuring strength, the amount of yarn used can also be effectively reduced, achieving the goal of saving yarn.

[0029] Example 5 This embodiment provides a warp-knitted sandwich mesh fabric that saves yarn, which has a structure largely the same as that provided in Embodiment 1, except that: (Refer to...) Figure 6 and Figure 7 As shown, the top layer 11, middle layer 12, and bottom layer 13 of the connecting region 2 all have a perforated structure 3. These perforated structures 3 can be staggered, such as... Figure 6 As shown, the surface layer holes 31, intermediate layer holes 32, and bottom layer holes 33 are staggered; alternatively, they can be arranged correspondingly, such as... Figure 7 As shown, the surface layer holes 31, the middle layer holes 32, and the bottom layer holes 33 correspond vertically and form a through hole. In this way, while ensuring strength, the amount of yarn used can also be effectively reduced, thus achieving the goal of saving yarn.

[0030] The above discloses several preferred embodiments of this solution. Of course, in other embodiments, as long as the connection area has sufficient strength, the location, number, and arrangement of the holes in the connection area are not limited to the above.

[0031] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
