Description

Technical Field

[0001] This utility model relates to the field of knitted fabric structure technology, and in particular to the field of warp-knitted jacquard fabric structure technology. Background Technology

[0002] Knitted fabrics are commonly used in shoe uppers. However, the knitted fabrics used in shoes are quite different from those used in clothing. Shoe uppers require knitted patterns or structures that highlight the appearance of the shoe, depending on the design. Therefore, compared to knitted fabrics used in clothing, shoes need more structural knitted structures to enhance the design, increase consumer appeal, and improve the competitiveness of fabric developers and product manufacturers.

[0003] Warp-knitted fabric, as a type of knitted fabric for shoe uppers, has different production characteristics and fabric effects compared to fly-knitted and woven fabrics. Therefore, it is a production method for realizing the design, production, and transformation of knitted shoe uppers. With the continuous changes in market trends and the diversification of trendy products, the development and design of incorporating trendy elements through warp knitting is still under continuous research and development. In view of this, the inventor of this case has devoted himself to research and development, resulting in this case. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-layered, trimmable, and customizable warp-knitted jacquard breathable mesh fabric. It is a novel type of warp-knitted jacquard mesh fabric that can be designed according to the application product, facilitating personalized trimming and customization by consumers.

[0005] To achieve the above objectives, the technical solution of this utility model is: a multi-layered, trimmable, warp-knitted jacquard breathable mesh fabric, which is integrally woven using a warp-knitting machine. Its yarns can be divided into bottom layer comb yarns, top layer comb yarns, and jacquard comb yarns between the bottom layer comb yarns and the top layer comb yarns. The top layer includes a woven merging area on the bottom layer connected by jacquard comb yarns and a woven separation area separated from the bottom layer to form a separation interlayer. The woven separation area has a trimming area edge line formed by a loop knitting structure with anti-loosening near the boundary of the woven merging area.

[0006] The trimming area of ​​the braided separation zone is knitted with a loop structure to prevent yarn breakage within the trimming area.

[0007] The jacquard comb yarns corresponding to the weaving separation zone are woven into jacquard patterns on the bottom layer.

[0008] The weaving separation zone is provided with connecting points or connecting strips at intervals, and the connecting points or connecting strips connect the surface layer and the bottom layer through Jacquard comb yarns.

[0009] The bottom comb yarn, the top comb yarn, and / or the jacquard comb yarn include color-changing yarns with an outer color-changing layer.

[0010] The knitting and merging area has through holes, and the jacquard comb yarns corresponding to the through holes are knitted on the bottom layer.

[0011] By adopting the above technical solution, the beneficial effects of this utility model are as follows: The warp-knitted jacquard breathable mesh fabric of the above structure achieves layering in the integrated weaving process by setting jacquard comb yarns (i.e., yarns threaded onto jacquard combs on warp knitting machines). These layers can be woven together and connected, or woven separately to form separate interlayers. Furthermore, the jacquard comb yarns can also be used for jacquard weaving. Thus, the mesh fabric design in applied products has a greater scope for creative expansion. For example, the upper layer includes a woven merging area and a woven separation area, with the woven separation area forming trimming edges. This structural design allows for personalized trimming and creation for consumers or customized products. In summary, the technical solution of this utility model provides a novel structure of warp-knitted jacquard mesh fabric, which can be personalized according to the design of the applied product, and is particularly suitable for fabric applications in shoes, clothing, hats, boxes, bags, and other products.

[0019] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0020] This embodiment discloses a multi-layered, trimmable, warp-knitted jacquard breathable mesh fabric, which is integrally woven using warp-knitting machinery. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the yarn arrangement on the warp knitting machine can be divided into 3 groups. The middle group is the yarn threaded on the jacquard comb, and the other two groups of yarn are arranged on both sides of the jacquard comb using ordinary combs. On the warp knitting machine, this yarn is threaded on the jacquard comb. The yarn on one side of the jacquard comb is the bottom comb yarn used to weave the bottom layer 1 of the mesh fabric, and the yarn on the other side of the jacquard comb is the top comb yarn used to weave the top layer 2. The yarn threaded on the jacquard comb is the jacquard comb yarn 3. In the mesh structure of this embodiment, the surface layer 2 includes a woven merging area 4 on the bottom layer 1 connected by Jacquard comb yarns 3, and a woven separation area 6 that separates from the bottom layer 1 to form a separation interlayer 5. This separation layer 5 and the woven separation area 6 thus provide a novel warp-knitted Jacquard mesh structure, which can be customized according to the product design, facilitating personalized trimming and creation by consumers. Consumers, designers, or custom-made products can personalize the shape and pattern of the woven separation area 6 to achieve different appearance effects. For example, as shown in the figure, the mesh is applied to knitted shoe uppers. Different areas of the shoe upper can be designed and trimmed. Trimming can also make the corresponding woven separation area 6 thinner and more breathable, resulting in more comfortable shoes. For shoe uppers, areas such as the toe, laces, and heel, as well as the connections between these areas, can be designated as woven merging areas to improve the structural strength of the knitted shoe upper. Figure 2 and Figure 4 The trimming position shown is designed to enhance the appearance of the knitted upper without affecting its structural strength. To avoid over-trimming and damaging the mesh fabric, the knitting separation area 6 in this invention features a trimming area edge line 7 formed by a loop-knitted structure near the junction of the knitting merging area. Figure 1 and Figure 3 As shown, by setting this line, the trimming boundary can be clearly seen during trimming, so that care can be taken not to cross it. In addition, the knitted loop structure that prevents fraying ensures that there will be no burrs or loose threads after trimming.

[0021] In addition to the trimming boundary being formed by using an anti-loose knitting loop structure to create the trimming area edge line 7, the trimming area edge line 7 of the knitting separation area 6 can also be knitted using an anti-loose knitting loop structure. This way, trimming any shape or pattern within the knitting separation area 6 can avoid the situation of having burrs or loose threads after trimming. Here, the anti-loose knitting loop structure refers to different loop structures formed by the movement of the needles on the warp knitting machine to pull the yarn. There are many known knitting loop structures, many of which can achieve the effect of preventing loose threads. There is no specific limitation here. Those skilled in the art can clearly select and set the corresponding knitting loop structure according to the desired effect.

[0022] In warp knitting, any yarn is always present on the mesh and extends in the warp direction for weaving. In this embodiment, the Jacquard comb yarn is used not only for the weaving connection between the surface layer 2 and the bottom layer 1, but also for weaving jacquard on the surface layer 2 and / or the bottom layer 1, thereby improving the appearance of the mesh. In this embodiment, since the weaving separation area 6 is a trimming area, the Jacquard comb yarn 3 corresponding to the weaving separation area 6 can be woven jacquard on the bottom layer. Alternatively, the weaving merging area of ​​the surface layer 2 is woven with through holes 21, and the Jacquard comb yarn 3 corresponding to the needle position of the through holes 21 is woven jacquard on the bottom layer 1. In this way, the appearance is realized through the structure. To further enhance the appearance, this embodiment can be further selected according to design needs, including color-changing yarn with an outer color-changing layer among the bottom comb yarn, top comb yarn and / or jacquard comb yarn 3. This yarn is an existing product, and the color-changing layer can be ultraviolet reaction color-changing, temperature change color-changing, humidity change color-changing, etc., and can produce color changes by external environmental factors. This setting, combined with trimming, can facilitate more diversified extended design and trimming creation.

[0023] Furthermore, to enhance the design and creative possibilities, this embodiment further incorporates structural features. Specifically, connecting points 8 or connecting strips 9 are spaced apart within the weaving separation zone 6. These connecting points 8 connect the surface layer 2 and the bottom layer 1 via Jacquard comb yarns. Figure 3 and Figure 4 As shown, the connection point 8 structure allows the trimming within the weaving separation zone 6 to retain the surface portion of the trimming creation. These surface portions further enhance the graphic of the trimming creation within the weaving separation zone 6, and the trimmed graphic presents a three-dimensional effect on the bottom layer 1, resulting in a more design-oriented and novel appearance. The connection points 8 can be arranged in regular dot or line arrays or irregular dot or line arrays, enabling a variety of regular or irregular trimming patterns. In terms of design and production, several creative examples can be provided for application products to guide consumers in creating more trimming designs.

[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.
