Description

Technical Field

[0001] This utility model relates to the field of warp-knitted material structure. Background Technology

[0002] Currently, cool and breathable fabrics are usually achieved through the selection of yarn materials and the setting of knitting structures. These fabrics are typically thin and soft, and are mainly used as clothing fabrics in the market.

[0003] There are currently no fabric products with this cooling and breathable effect for knitted shoe uppers. The aforementioned cooling and breathable fabrics, which are mainly used in clothing, are too thin and soft to meet the performance standards required for shoe upper materials.

[0004] Based on people's ideal requirements for shoe comfort, the professional team in this case conducted innovative research and development on the knitted fabric used for the shoe upper, which has the comfort properties of breathability and coolness, and thus this case came about. Summary of the Invention

[0005] The purpose of this invention is to provide a jacquard upper material that has both a cool and breathable comfort effect and meets the relevant structural performance standards for knitted shoe uppers.

[0006] To achieve the above objectives, the technical solution of this utility model is: a jacquard shoe upper material with a cooling and breathable effect, which is a warp-knitted integrated fabric structure, including a cooling and breathable area. The cooling and breathable area includes a surface yarn, an inner yarn, and jacquard yarn. The surface yarn is knitted to form the surface layer of the knitted shoe upper, and the inner yarn is knitted to form the inner layer of the knitted shoe upper. The inner layer includes a jacquard base row composed of multiple adjacent warp yarns and a tightening row composed of multiple adjacent warp yarns, which are arranged alternately. The jacquard yarn includes a face-inner connecting row composed of multiple adjacent warp yarns and a cooling jacquard row composed of multiple adjacent warp yarns, which are arranged alternately. The face-inner connecting row connects the surface layer and the inner layer knitted together with the tightening row. The cooling jacquard row is jacquard on the inner layer corresponding to the jacquard base row. The jacquard yarn in the cooling jacquard row is a cooling yarn with a cooling effect, and the jacquard yarn in the tightening row is a tightening yarn that can handle shrinkage.

[0007] The number of knitting needles in the face-to-face connecting column is less than the number of knitting needles in the tightening column and is centered. The number of knitting needles in the cool-feel jacquard column is less than the number of knitting needles in the jacquard base column and is centered. There are empty needle positions between two adjacent face-to-face connecting columns and cool-feel jacquard columns corresponding to the face and inner layers.

[0008] The cool-feel jacquard pattern consists of multiple adjacent jacquard yarns knitted together at the same needle position onto the inner layer, and knitted on the same jacquard base row to form multiple strands.

[0009] The outer layer and inner layer of the corresponding tightening column are not connected, and the outer layer is knitted with warp-spaced knitting to form breathable holes.

[0010] By adopting the above technical solution, the beneficial effects of this utility model are:

[0011] 1. The jacquard shoe upper material with the above structure is knitted in one piece by a warp knitting machine, which is convenient for production and manufacturing.

[0012] 2. The above structural design allows the cooling jacquard pattern to make easier contact with the feet, achieving heat conduction and cooling to realize the cooling effect. Further structural design creates airflow space and improves breathability and cooling effect.

[0013] 3. The double-layer structure, combined with jacquard yarn and the ability to combine different yarns, helps the fabric's structural strength meet the performance standards required for shoe uppers.

[0014] In summary, the above-mentioned objectives of this utility model are achieved. Attached Figure Description

[0020] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0021] This embodiment discloses a jacquard upper material with a cooling and breathable effect. It is a warp-knitted fabric structure. Knitted uppers typically achieve different patterned effects in different areas through the knitted structure. The structure of this invention can be a portion of the upper, such as a cooling and breathable area on the front or sides where breathability is needed. Alternatively, the entire upper can be a cooling and breathable area. This invention primarily improves the structure of the cooling and breathable area; therefore, this embodiment only describes this improved structure. Figure 1 , Figure 2 and Figure 3 The diagram shows a cross-section of the fabric in the weft direction, illustrating the structure. The cool and breathable area includes a face yarn 10, an inner yarn 20, and a jacquard yarn 30. On a warp knitting machine, the face yarn 10 and inner yarn 20 are threaded through different guide bars, while the jacquard yarn 30 is threaded through the jacquard guide bars. Typically, the jacquard guide bars are positioned between the guide bars through which the face yarn 10 is threaded and the guide bars through which the inner yarn 20 is threaded. The face yarn 10 knits to form the face layer 1 of the knitted shoe upper, and the inner yarn 20 knits to form the inner layer 2 of the knitted shoe upper. The inner layer 2 includes a jacquard base row 21 composed of multiple adjacent warp yarns and a tightening row 22 composed of multiple adjacent warp yarns, with the two arranged alternately (i.e., as shown). Figure 1 The jacquard base row 21 is arranged in a regular pattern with an alternate tightening row 22. The jacquard yarn includes a face-to-inner connecting row 31 composed of multiple adjacent warp yarns and a cool-feel jacquard row 32 composed of multiple adjacent warp yarns, and the two are arranged alternately. The face-to-inner connecting row 31 knits the face layer 1 and the inner layer 2 together with the tightening row 22. The cool-feel jacquard row 32 is jacquard on the inner layer 2 corresponding to the jacquard base row 21. The jacquard yarn of the cool-feel jacquard row 32 is a cool-feeling yarn with a cooling effect. The jacquard yarn of the tightening row 22 is a tightening yarn that can be treated (such as post-heat treatment) to shrink.

[0022] The above structure is achieved by: the inner layer 2 comprising an alternating arrangement of jacquard base row 21 and tightening row 22; the jacquard yarn face-to-face connecting row 31 corresponding to the tightening row 22 to knit the face layer 1 and the inner layer 2 together; the tightening row 22 is tightening yarn (an existing material, readily available on the market, which is typically further shrunk and shaped after heat setting treatment of the shoe upper); and the cool-feel jacquard row 32 corresponding to the jacquard base row 21 jacquard on the inner layer 2, thus... Figure 2As shown, after knitting, the jacquard yarn of the cooling jacquard row 32 protrudes from the surface of the inner layer 2. Combined with the adjustment of the stitch count, the cooling jacquard row 32 can contact the foot first. Since the jacquard yarn of the cooling jacquard row 32 uses a cooling yarn with a cooling effect (existing material, with heat conduction and cooling effect, which can be directly purchased on the market), it can make the foot feel cool and has a certain effect of blocking part of the inner layer 2 from contacting the foot. The tightening row 22 can shrink and tighten the fabric after the fabric is processed, and at the same time, it can shorten the distance between two adjacent cooling jacquard rows 32, which further blocks the inner layer 2 from contacting the foot. The tightening of the tightening row 22 also causes the surface layer 1 to be slightly arched and deformed. The surface layer 1 is not connected to the inner layer 2, which is conducive to increasing the space for internal air flow. Correspondingly, the surface layer 1 of the tightening row 22 can be knitted with warp-spaced ventilation holes 11. In this way, the ventilation holes on the surface layer 1 can further effectively achieve the ventilation effect and improve the cooling effect.

[0023] To further enhance the above-mentioned effects, this embodiment further includes the following: Figure 1 and Figure 2 As shown, the number of stitches in the connecting column 31 is less than that in the tightening column 22, and the tightening column 22 is centered. The number of stitches in the cooling jacquard column 32 is less than that in the jacquard base column 21, and the cooling jacquard base column 21 is centered, creating a height difference effect. A groove is formed between the two cooling jacquard columns 22 in the inner layer 2, which reduces the amount of fabric covering the foot and increases airflow space. The connecting column 31 and the cooling jacquard column 32 are both yarns from the Jacquard comb. On the Jacquard comb, there are empty stitches between two adjacent connecting columns 31 and cooling jacquard columns 32 corresponding to the outer layer 1 and the inner layer 2, as shown in the figure. The empty stitches allow the formed shoe upper to form a gap between the outer layer 1 and the inner layer 2, which also helps the tightening column 22 to cause the outer layer 1 to slightly arch and deform. This further enhances the intended effect of this invention. Furthermore, to further enhance the effect, in this embodiment, the cooling jacquard row 32 consists of multiple adjacent jacquard yarns knitted together at the same needle position onto the inner layer 2 and knitted together on the same jacquard base row 21 to form multiple strands. Multiple jacquard yarns knitted together can increase the thickness and increase the height of the jacquard protrusion, while multiple strands form multiple warp jacquard rows on the jacquard base row 21, which can increase the cooling contact area and enhance the cooling effect.

[0024] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
