Description

Technical Field

[0001] This invention relates to an electroembroidery combined with a differentiated shoe upper and its preparation method, belonging to the field of electroembroidery. Background Technology

[0002] Electroembroidery, as a traditional decorative technique, is widely used in footwear and apparel to enhance their aesthetic value. In recent years, with technological advancements, combining color with embroidery has become an industry trend, with dyeing electroembroidery being a prime example.

[0003] Currently, the industry's advanced solution is exemplified by the real-time dyeing technology from Coloreel, a Swedish company. This technology dyes the embroidery thread in real time during the embroidery process, enabling the creation of colorful patterns. However, this technology faces several significant limitations in practical application: First, the dedicated dyeing equipment is extremely expensive, posing a significant financial barrier for many small and medium-sized embroidery enterprises and individual practitioners, severely restricting its market adoption. Second, the technology is complex to operate, requiring operators to possess advanced digital skills and a deep understanding of embroidery techniques, necessitating substantial time and effort for learning, thus increasing the technical difficulty and labor costs. Third, the maintenance, upkeep, and even troubleshooting of this highly integrated equipment require specialized technicians and substantial costs; any problems can directly impact production schedules, resulting in persistently high maintenance costs.

[0004] In addition to the promotional difficulties faced by solutions based on high-end equipment, traditional dyeing and embroidery techniques also have inherent technical defects: First, to ensure the uniformity and accuracy of the dyeing effect, reverse or complex cross-stitching is usually not allowed, otherwise it will seriously damage the color layout and continuity. Moreover, dyeing is difficult in complex stitching, which can easily cause color confusion, wrong colors, and color skipping, which greatly restricts the complexity and artistic expression of the pattern design. Second, it is difficult to convert the designed complex pattern into a program that can be recognized by the embroidery machine. The more complex the pattern, the more cumbersome the conversion process becomes, and it is easy to have problems such as pattern deformation, uneven lines, and harsh color transitions in the final product. Furthermore, the traditional thread dyeing process requires the use of a large amount of dyes and auxiliaries containing chemical substances, and the discharge of its production wastewater puts a great deal of pressure on the environment, which is not in line with the current trend of green and environmentally friendly manufacturing development. Summary of the Invention

[0005] In view of the shortcomings of existing technologies, the purpose of this invention is to provide an electro-embroidery combined with differentiation shoe upper and its preparation method, so as to solve the technical barriers of electro-embroidery coloring without relying on expensive professional equipment, and at the same time overcome the defects of traditional processes in terms of design freedom, production complexity and environmental protection.

[0006] To achieve the above objectives, the present invention provides a technical solution as follows: an electro-embroidered and differentiated shoe upper, comprising: The base layer of the shoe upper; A three-dimensional embroidery layer, wherein the three-dimensional embroidery layer is formed by fixing embroidery threads to the shoe upper base layer through an electric embroidery process to form at least one pattern area, and at least a portion of the embroidery threads protrude from the surface of the shoe upper base layer to form a three-dimensional texture; The colored layer is a continuous layer that integrally covers and is fixed to the outer surface of the three-dimensional texture and the surface of the shoe upper base layer that is not covered by the three-dimensional embroidery layer.

[0007] Furthermore, the embroidery thread trajectory forms intersecting nodes and / or backstitch segments; the color layer is a continuous layer and covers the intersecting nodes and / or backstitch segments.

[0008] Furthermore, at least two patterned areas are formed on the base layer of the shoe upper, and each patterned area is distinguished from the other in terms of embroidery thread density and / or embroidery thread direction.

[0009] Furthermore, the spatial relationship between the different patterned areas on the base layer of the shoe upper is adjacent and / or partially overlapping.

[0010] Furthermore, the thread density within at least one of the pattern areas is non-uniformly distributed to create a transition effect within the pattern area.

[0011] Furthermore, the high-density portion of the embroidery thread is formed at the outline boundary of the pattern area, and the low-density portion of the embroidery thread is formed in the inner region enclosed by the outline boundary.

[0012] The "high-density section" and "low-density section" of the embroidery thread are relative to the overall average density of the embroidery thread arrangement within the same pattern area. The difference in the density of the embroidery thread arrangement creates a transition in visual and physical properties within the pattern area.

[0013] In practice, the density of stitches per unit area (stitches / square centimeter) can be used to define the area. For example, the thread density of the high-density area can be more than 20% higher than that of the low-density area in the same pattern area, preferably 30%-50% higher, to ensure the achievement of a smooth transition effect.

[0014] Furthermore, the density of the embroidery thread arrangement decreases gradually from the outline boundary of the pattern area towards the central region.

[0015] Furthermore, the colored layer is attached to the three-dimensional embroidery layer and the shoe upper base layer through a heat transfer process.

[0016] A method for preparing an electro-embroidered and differentiated shoe upper, characterized in that the preparation method includes the following steps: S1. Electroembroidery support step: A water-soluble film is laid on the base layer of the shoe upper, and electroembroidery is performed according to the preset pattern, so that the embroidery thread passes through the water-soluble film and the base layer of the shoe upper to form an electroembroidery composite with three-dimensional texture. S2, Pattern transfer step: Align the transfer medium carrying the preset color pattern with the embroidery composite, and transfer and fix the preset color pattern to the outer surface of the embroidery composite by hot pressing to form a composite with an integrated color layer on the surface. S3, Water washing and shaping step: The electro-embroidered composite material after step S2 is washed with water to dissolve and remove the water-soluble film, and then dried to obtain the electro-embroidered composite shoe upper.

[0017] Furthermore, the transfer medium includes transfer paper or transfer film, and the preset color pattern is pre-printed on the transfer paper or transfer film by digital printing.

[0018] The beneficial effects of this invention are: The electro-embroidery combined with the differentiated upper of this application constitutes a three-dimensional composite structure consisting of an upper base layer, a three-dimensional embroidery thread layer, and a colored layer. The three-dimensional embroidery thread layer constructs raised three-dimensional textures in specific areas of the upper through free intersection and reverse stitching, realizing diversified functional zones from local reinforcement and support to guiding airflow. The integrated colored layer covering it serves as a continuous functional layer, seamlessly wrapping and fixing to all embroidery threads and the base surface, visually integrating the complex physical structure into a complete pattern with rich colors, natural transitions, and a strong three-dimensional feel, forming a high degree of unity between rich colors and complex three-dimensional aesthetics.

[0019] The preparation method described in this application employs a process route of "first constructing a three-dimensional skeleton, then applying color in an integrated manner." First, a water-soluble film is applied to the base layer of the shoe upper, followed by free-path electro-embroidery to construct an embroidered composite with complex three-dimensional patterns. During this process, the water-soluble film provides crucial support for complex stitching, including cross-cutting and reverse-cutting. Subsequently, a digital color pattern is transferred to the entire outer surface of the embroidered composite in a single, integrated manner using heat transfer technology. This allows color molecules to firmly penetrate the embroidery thread and base layer, forming a seamless, integrated color layer. Finally, the water-soluble film, a temporary supporting structure, is dissolved and removed by washing, revealing the pure three-dimensional embroidery thread and completing the shaping process. The embroidery thread is not limited by dyeing processes, enabling the creation of arbitrarily complex three-dimensional structures and intricate pattern designs, offering greater design freedom. This method eliminates the need for expensive professional dyeing equipment, significantly reducing production costs and technical barriers. Furthermore, the heat transfer process generates minimal pollution, and the washing step only dissolves the unpolluted water-soluble film. The production process is dye-free, fundamentally avoiding the chemical pollution of traditional dyeing processes and achieving efficient, economical, and environmentally friendly green manufacturing.

Second pattern area; 212a. Circular area; 212b. Outer contour boundary line; 212c. Inner filled plane part; 213. Third pattern area. Detailed Implementation

[0022] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0023] It should be noted that the scope of protection of this application is not limited to a specific pattern layout. Those skilled in the art, upon understanding the core technology of this application—that is, constructing a three-dimensional texture through a three-dimensional embroidery layer and then covering it with an integrated color layer—can flexibly change the specific position, shape, and quantity of the pattern area according to the aesthetic or functional requirements of the product. Specific implementation method one: In this application Figure 1 , Figure 2 Taking this as an example, the shoe upper includes several pattern areas 21, wherein the first pattern area 211 is located at the top of the shoe upper, the second pattern area 212 is partially connected to the first pattern area and is located in the middle of the shoe upper, and the third pattern area 213 is symmetrically arranged on the left and right sides of the shoe upper along the length direction of the shoe upper.

[0025] This invention provides a technical solution for combining electroembroidery with a differentiated shoe upper, comprising: Upper base layer 1; Three-dimensional embroidery layer 2, wherein the three-dimensional embroidery layer 2 is formed by fixing embroidery thread to the shoe upper base layer 1 through an electric embroidery process to form at least one pattern area 21, and at least part of the embroidery thread protrudes from the surface of the shoe upper base layer 1 to form a three-dimensional texture. Color layer 3, which integrally covers and is fixed to the outer surface of the three-dimensional texture and the adjacent surface of the shoe upper base layer 1, is a continuous film layer.

[0026] Example 1: This embodiment aims to describe how differentiated embroidery thread density in specific key areas of the same upper enables precise regional functional enhancement. This design allows the upper to maintain overall lightweight and flexibility while achieving significantly enhanced physical properties in areas requiring additional support, deformation resistance, or abrasion resistance. Reference Figure 1 As shown, the upper of this embodiment includes a second pattern area 212. Within this pattern area 21, the embroidery thread density is not uniform, but is precisely configured according to the functional requirements of each area. This is specifically reflected in the following two levels of differentiated design: 1. Local reinforcement of key stress points: Within the second pattern area 212, the annular area 212a surrounding the eyelet has a significantly higher embroidery density than the rest of the second pattern area 212. For example, the average embroidery density of this high-density annular area 212a can reach 6-8 stitches / cm², while the density of the surrounding background area is 2-4 stitches / cm².

[0027] This application creates a structural reinforcement ring by setting high-density embroidery at the eyelet, which effectively disperses and transmits the tension of the shoelaces, greatly reducing the risk of the fabric around the eyelet being torn or excessively deformed due to long-term stress, thereby improving the local durability and overall structural stability of the shoe upper.

[0028] 2. Structural definition of pattern outline Furthermore, within the second pattern area 212, the embroidery thread density of its outer contour boundary line 212b is designed to be greater than the embroidery thread density of the inner filling plane portion 212c connected to the outer contour.

[0029] The high-density design of the outline clearly and firmly defines the geometry of the pattern, enhancing the structural rigidity of the area and better resisting lateral stress. This prevents the pattern from twisting and deforming during daily wear and bending. In addition, the dense outline contrasts with the relatively loose internal filling. After being covered with an integrated color layer 3, it presents a unique visual effect with clear outlines and rich internal texture, enhancing the three-dimensionality and layering of the pattern.

[0030] In summary, this embodiment, through the refined design of embroidery thread density in the aforementioned key areas, successfully endows the decorative pattern area 21 with a clear structural function, achieving a deep integration of aesthetics and functionality, and fully demonstrating the powerful capabilities of the invention in personalizing and optimizing the performance of shoe uppers.

[0031] It should be noted that this embodiment only uses the second pattern area 212 as an example for illustrative purposes. Those skilled in the art will understand that the design concept of enhancing functionality based on embroidery thread density described above is also applicable to the other pattern areas 21 on the shoe surface.

[0032] Example 2: This embodiment aims to describe in detail how by designing embroidery lines with specific directions in different areas of the same shoe upper, a dynamic visual transition effect and precise functional guidance can be achieved. This design not only makes the shoe upper present a unique flowing aesthetic, but also endows different areas with differentiated physical properties to adapt to the complex needs of the foot during movement.

[0033] Reference Figure 1 As shown, the upper of this embodiment includes multiple pattern areas 21, and the dominant direction of the embroidery thread in each area is specially designed according to its position and function: 1. First pattern area 211: The first patterned area 211 is located at the top of the upper, corresponding to the main flexing area of ​​the forefoot. The dominant direction of the embroidery thread in this area is designed to be arranged longitudinally parallel to the length of the upper. This longitudinal direction of the embroidery thread provides optimal longitudinal flexibility for this key flexing area, ensuring that the upper can flex smoothly and unrestricted during gait cycles, greatly improving dynamic comfort.

[0034] 2. Second pattern area 212: The second pattern area 212 is located in the middle of the upper and partially connects with the first pattern area 211. It corresponds to the midfoot area that needs to provide support and stability. The dominant direction of the embroidery threads in this area changes to a horizontal arrangement perpendicular to the length of the upper. This horizontally oriented embroidery thread effectively limits the lateral deformation of the upper, acting like a built-in stabilizing band, enhancing the midfoot's wrap-around feel and locking effect, and preventing lateral slippage of the foot during movement.

[0035] Furthermore, the horizontal lines form a striking geometric contrast with the vertical lines of the first pattern area 211, visually emphasizing the stability and power of the midfoot and echoing the support function of this area.

[0036] 3. Third pattern area 213: The third pattern area 213 is symmetrically arranged on the left and right sides along the length of the shoe upper, corresponding to the area of ​​the foot that requires lateral support. The main direction of the embroidery thread in this area is designed to be diagonally arranged at an angle of 45° to 60° with the length of the shoe upper. The diagonally arranged embroidery thread effectively resists impact and pressure from the sides, providing excellent lateral support and stability for the foot, while maintaining a certain degree of flexibility in the longitudinal direction to avoid stiff movement.

[0037] 4. Visual transition between areas: Specifically, at the junction of the first pattern area 211 and the second pattern area 212, the direction of the embroidery thread smoothly and gradually transitions from the vertical direction to the horizontal direction. This gradual change in direction leads to a continuous change in the angle of light reflection, causing the colored layer 3 covering it to present a soft gloss gradient and a unique micro-shadow effect in this transition area, creating a natural and smooth visual connection and integrating areas with different functions into an organic whole.

[0038] This embodiment achieves "zoning customization" from visual to functional by precisely matching the embroidery thread direction to the layout of specific functional areas on the shoe upper.

[0039] Example 3: This embodiment aims to describe how the shoe upper, through the overlapping projections of different pattern areas 21 onto the base layer of the shoe upper, constructs a rich structural hierarchy that is physically composite, functionally synergistic, and visually unified: For example: refer to Figure 1 The third pattern area 213 is located in the lower layer, and its embroidery thread is arranged with a low density, such as 2-3 stitches / square centimeter and an open direction in the form of a mesh or wavy pattern; the second pattern area 212 is located in the upper layer, and its embroidery thread is arranged with a high density, such as 6-8 stitches / square centimeter and a dense linear direction, and partially covers the third pattern area 213, thereby forming a composite embroidery thread layer in the overlapping area that combines a bottom open structure with a top closed structure.

[0040] In the non-overlapping areas, the open structure of the third pattern zone 213 ensures excellent basic breathability and achieves a lightweight design. In the overlapping areas, due to the higher thread density and thickness, localized reinforcements or supporting frameworks naturally form on the upper, providing crucial mechanical support. This allows the upper to be reinforced in key areas while effectively controlling the overall weight. After the integrated color layer 3 is applied over this composite structure, the overlapping areas will exhibit a deeper color or unique micro-shadow effect than other areas due to the different reflection and shading effects of the open grid at the bottom and the dense lines at the top. This creates a visual layer with inherent depth using only a single-color coating without the use of multi-color printing.

[0041] Furthermore, the overlapping areas have a noticeable raised texture compared to the non-overlapping areas. When users touch them with their fingers, they can feel the subtle undulations caused by the overlapping embroidery threads, which greatly enhances the texture and recognizability of the product.

[0042] Therefore, this embodiment extends the structural characteristics of the embroidery thread from a two-dimensional plane to a three-dimensional space through the creative overlapping design of different pattern areas 21, realizing the unification of seemingly contradictory performances such as breathability, support, and lightweight on a single shoe surface, and simultaneously giving the product a rich visual and tactile experience. Specific Implementation Method Two: Reference Figure 4 As shown, the present invention provides a technical solution for a method of preparing an electro-embroidered and differentiated shoe upper, which includes: S1. Embroidery support steps: Prepare a one-piece flyknitted mesh as the base layer 1 of the shoe upper, fix it flat on the frame of the computer embroidery machine, and then tightly cover it with a water-soluble film. The designed digital pattern, including cross nodes and backstitch segments, is imported into the embroidery machine, and polyester embroidery thread is used for embroidery. During this process, the water-soluble film provides crucial temporary support for all the complex cross and backstitching, ensuring the precise forming of the three-dimensional embroidery layer 2 without any loosening or twisting of the embroidery thread, ultimately forming a robust embroidery composite.

[0044] S2. Pattern transfer steps: Using a digital inkjet printer, a pre-set pattern with gradient colors is precisely printed onto a thermal sublimation transfer paper in a mirror manner, and the patterned side of the printed transfer paper is aligned and bonded to the embroidery surface of the embroidery composite obtained in step S1. The material is fed into a heat transfer machine and held at 185°C and 0.4 MPa for 12 seconds. During this process, the disperse dye on the transfer paper sublimates upon heating, and the gaseous dye molecules firmly penetrate and adhere to the surface of the polyester embroidery fibers and the flywoven mesh. After cooling, the transfer paper is removed, resulting in a composite material with a highly integrated, continuous, and uninterrupted color layer 3 on the surface.

[0045] S3. Washing and setting steps: The composite obtained in step S2 is placed in a constant temperature flowing water bath at 35°C and soaked for 25 minutes. During this period, the water-soluble film is completely dissolved in the water. After removal, it is gently rinsed with clean water to thoroughly remove any residual water-soluble film components and any floating color.

[0046] The cleaned shoe uppers are then placed in a 70°C circulating air oven and dried for about 15 minutes to set their shape. After drying, the final product of the electro-embroidered and differentiated shoe uppers is obtained.

[0047] Example 1: The difference in this embodiment lies in the pattern transfer step, which provides an alternative transfer scheme suitable for use on materials requiring high opacity or on materials where sublimation dyes are not applicable.

[0048] S1. Embroidery support step: This step is exactly the same as the preparation method.

[0049] S2. Pattern transfer steps: A transfer film coated with a hot melt adhesive layer is used as the transfer medium. The pattern is pre-placed on it by digital printing. After the two are aligned, they are hot-pressed for 18 seconds at a temperature of 150℃ and a pressure of 0.5MPa. During this process, the hot melt adhesive layer melts and carries the color pigments rather than dyes to adhere to the surface of the embroidery thread and the shoe upper base layer. After cooling, an integrated color layer 3 is formed.

[0050] S3. Water washing and setting step: This step is similar to the preparation method, but because the hot melt transfer layer may be slightly water-resistant, the water washing and soaking time can be appropriately extended to 30-40 minutes to ensure that the water-soluble film is completely dissolved.

[0051] The preparation method provided by this invention, through a disruptive process route of "first constructing a three-dimensional skeleton and then applying color in an integrated manner," successfully bypasses the dependence of traditional dyeing and embroidery on expensive specialized equipment such as Coloreel, as well as its technical limitations in the direction of embroidery threads. By introducing a water-soluble film, it achieves high degree of freedom and complex three-dimensional embroidery. The subsequent heat transfer step simplifies the complex "dyeing" process into an efficient "printing" process, combining the two separate "structural processing" and "color processing" stages in the traditional process into one, greatly simplifying the process, reducing production costs and energy consumption, and fundamentally reducing the discharge of chemical dye wastewater. It is environmentally friendly. This preparation method provides a new, efficient, economical, and environmentally friendly path for producing integrated shoe uppers with both complex three-dimensional structures and rich colors.

[0052] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.

Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0053] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
