Description

Technical Field

[0001] This application relates to the field of textile embroidery technology, and in particular to a method for preparing a three-dimensional embroidery component with a three-dimensional convex-concave 3D visual effect, the three-dimensional embroidery component obtained by the method, and textile articles containing the component. Background Technology

[0002] Traditional computer embroidery primarily creates patterns on flat fabric using multi-colored stitches, resulting in a visual effect limited to a two-dimensional plane and lacking a realistic three-dimensional feel. Although 3D decorative flowers made of plastic or resin exist on the market, their stiff texture and lack of flexibility prevent them from blending well with textiles and make them difficult to mass-produce using conventional embroidery equipment.

[0003] While some existing water-soluble embroidery techniques can achieve openwork or slight relief effects, they lack effective structural support and controllable deformation mechanisms, making it difficult to stably present a single-sided, durable, and customizable three-dimensional raised and recessed 3D effect. In addition, when applied to outdoor or high-frequency use scenarios, existing embroidery structures are prone to deformation and collapse due to changes in temperature and humidity or mechanical compression, resulting in insufficient durability.

[0004] Therefore, there is an urgent need for a new embroidery technique that can achieve a controllable, stable, and durable single-sided stereoscopic 3D visual effect on flexible textile substrates, while being compatible with existing embroidery equipment and supporting large-scale production. Summary of the Invention

[0005] The first objective of this application is to provide a method for preparing embroidery patterns with a three-dimensional convex-concave 3D visual effect, thereby solving the problems of planar embroidery patterns, unstable three-dimensional effect, and poor durability in the prior art.

[0006] To achieve the above objectives, this application provides a first technical solution with a weak three-dimensional effect: a method for preparing a three-dimensional embroidery component, comprising the following steps: S1: Provide a soluble auxiliary material layer as a support base layer, and stack at least one layer of shaped base fabric on it to form a composite structure of at least two layers.

[0007] S2: Embroider the edges of the shaped base fabric and trim away any excess parts that exceed the preset pattern outline.

[0008] S3: Embroider the entire structure, which consists of at least two layers after cutting, through all layers.

[0009] S4: Based on the overall embroidery, use flat embroidery or a combination of flat embroidery and soluble embroidery thread to embroider patterns.

[0010] S5: Place the embroidered component in a solvent to dissolve and remove the soluble auxiliary material layer or its soluble embroidery thread, thereby obtaining a preliminary three-dimensional embroidered component.

[0011] S6: The preliminary three-dimensional embroidery component is placed in a shaping mold for heat shaping treatment. Relying on the structural rigidity of the shaping base fabric and the tension of the embroidery thread, a single-sided three-dimensional visual effect with slight concavity or near-flatness is formed.

[0012] The first technical solution adopts a double-layer structure of soluble auxiliary material layer and shaping base fabric, combined with edge shaping embroidery, overall fixing embroidery and selective water-soluble embroidery process. After removing soluble components, the shaping base fabric itself has low heat shrinkage rate and structural rigidity, and with the tension of embroidery thread, a stable and controllable slight concave or near-flat single-sided 3D visual effect is formed during the heat shaping process.

[0013] Compared to traditional flat embroidery, this solution achieves a light three-dimensional decorative effect with a simpler structure and lower cost without introducing additional heat-shrinkable materials. It is suitable for patterns that do not require a high degree of three-dimensionality but emphasize the clarity of the outline and durability (such as brand logos, geometric lines, etc.), while also having good production efficiency and process compatibility.

[0014] To achieve the above objectives, this application provides a second technical solution with a strong three-dimensional effect: a method for preparing a three-dimensional embroidery component, comprising the following steps: S1: A soluble auxiliary material layer is provided as a support base layer, and a shaped base fabric is stacked on the soluble auxiliary material layer, and the edge area of ​​the shaped base fabric is shaped and rusted. S2: A heat-shrinkable fabric is stacked on the shaped base fabric, and the shaped base fabric and the heat-shrinkable fabric are arranged adjacent to each other in the thickness direction to form a multi-layered structure; then, the edge area of ​​the heat-shrinkable fabric is shaped and embroidered, and the excess part that exceeds the outline of the preset pattern is cut off; wherein, the heat shrinkage rate of the shaped base fabric is less than the heat shrinkage rate of the heat-shrinkable fabric. S3: Embroider the cut multi-layered structure through each layer to fix the base fabric, the heat shrink fabric and the soluble auxiliary material layer into one piece and form the basic skeleton of the pattern. S4: Based on the overall embroidery, use flat embroidery or a combination of flat embroidery and soluble embroidery thread to embroider the pattern details; S5: Place the embroidered component in a solvent to dissolve and remove the soluble auxiliary material layer or its soluble embroidery thread, thereby obtaining a preliminary three-dimensional embroidered component; S6: The preliminary three-dimensional embroidery component is placed in a shaping mold for heat shaping treatment. By utilizing the difference in heat shrinkage properties between the shaping base fabric and the heat shrink fabric, the pattern of the three-dimensional embroidery component undergoes controllable deformation in a localized area, thereby creating a concave-convex 3D visual effect on a single side.

[0015] The second technical solution employs a three-layer composite structure: a soluble auxiliary material layer, a low-shrinkage shaping base fabric, and a high-shrinkage heat-shrinkable fabric. During the heat-setting process, the significant difference in heat shrinkage properties between the base fabric and the heat-shrinkable fabric allows for directional and controllable shrinkage deformation in specific areas of the pattern. This results in a distinctly raised edge, clear layers, and a strong sense of depth on a single side. Simultaneously, layered edge-shaping embroidery and overall fixing embroidery ensure the multi-layered structure remains stable during processing. The synergistic dissolution of water-soluble embroidery thread and soluble auxiliary materials allows for the removal of supports while preserving a clean, three-dimensional outline. This solution is particularly suitable for decorative patterns requiring high three-dimensional expressiveness, such as flowers, animals, and reliefs, and the resulting components exhibit excellent morphological stability and durability.

[0016] In one embodiment, the heat shrinkage rate of the shaped base fabric is less than 5% at a temperature greater than or equal to 150°C. This ensures that the shaped base fabric maintains dimensional stability during the high-temperature sizing process, effectively resisting deformation as a structural support layer, thus creating a striking contrast with the heat-shrinkable fabric and providing a reliable rigid foundation for the three-dimensional textured effect.

[0017] In one embodiment, the heat-shrinkable fabric has a heat shrinkage rate of greater than 10% at a temperature greater than or equal to 150°C. This heat shrinkage performance is sufficient to generate significant and controllable shrinkage force at conventional heat-setting temperatures, driving the pattern to locally arch upwards or concave inwards, which is a key driving force for achieving a strong stereoscopic 3D visual effect.

[0018] In one embodiment, the heat-shrinkable fabric is one or more of polyester taffeta, heat-shrinkable polyester, or nylon heat-shrinkable fabric; the shaping base fabric is woven fabric, high-density polyester fabric, or memory fabric. All of the above materials are commercially available, cost-effective, and stable textile raw materials, possessing both good embroidery properties and thermal response characteristics, facilitating industrial mass production while ensuring the smooth appearance and structural durability of the three-dimensional components.

[0019] In one embodiment, the heat setting temperature is 160°C to 230°C, preferably 190°C; the heat setting time is 10 seconds to 30 seconds, preferably 19 seconds; and the heat setting working pressure ranges from 800 kPa to 1000 kPa.

[0020] The above temperature range can fully activate the shrinkage performance of the heat shrink fabric while avoiding excessive temperature that could cause the fabric to char or the embroidery thread to melt. It balances deformation efficiency and material integrity and is suitable for embroidery patterns of different thicknesses and complexities.

[0021] In one embodiment, the soluble auxiliary layer is water-soluble paper, water-soluble nonwoven fabric, or water-soluble film. This auxiliary layer possesses excellent support and complete water solubility, stabilizing the multi-layered structure during the embroidery process and dissolving completely without residue during post-processing, ensuring a clean surface and no hard residue on the final three-dimensional embroidered component.

[0022] In one embodiment, the solvent is water, and the temperature is not lower than 80°C. Using hot water as a solvent is safe, environmentally friendly, and cost-effective; temperatures above 80°C can accelerate the dissolution rate of water-soluble auxiliary materials and embroidery threads, shorten post-processing time, and improve production efficiency.

[0023] In one embodiment, the cutting method is laser cutting, ultrasonic cutting, or mechanical die-cutting. All of these cutting methods can achieve high-precision contour trimming, preventing fabric frayed edges. In particular, laser and ultrasonic cutting can simultaneously seal the edges, improving edge neatness and the stability of subsequent embroidery.

[0024] In one embodiment, the patterned embroidery also includes fishing line, thermoforming thread, or shape memory alloy thread. Introducing functional threads such as fishing line can further enhance local support; thermoforming thread enables secondary thermoforming; and shape memory alloy thread provides dynamic recovery capability, expanding the functionality and design possibilities of three-dimensional embroidery components.

[0025] The second objective of this application is to provide a three-dimensional embroidered component, which is made by any of the methods described above. This three-dimensional embroidered component does not require additional adhesive or rigid substrate, and is entirely composed of textile materials and embroidery thread. It is soft, flexible, and has strong conformability, making it suitable for curved substrates. At the same time, its three-dimensional effect comes from the inherent thermal shrinkage difference of the material and the structural design, and does not rely on external support. Therefore, it can maintain its design aesthetics and functional integrity for a long time even under repeated use or harsh environments.

[0026] The third objective of this application is to provide a textile article whose surface is provided with the aforementioned three-dimensional embroidered components. The textile article can be clothing, bags, shoes, hats, home textiles, or automotive interior parts. This textile article not only possesses a highly recognizable and artistically expressive 3D decorative effect, but also, due to the excellent structural stability and durability of the three-dimensional embroidered components, it can maintain its three-dimensional shape without collapsing, delaminating, or deforming even under frequent friction, bending, temperature and humidity changes, or long-term use, significantly improving the product's aesthetics, quality, and lifespan.

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions in the embodiments of this invention will be clearly and completely described below in conjunction with the embodiments of this invention. Those skilled in the art should understand that the embodiments described are merely illustrative of the invention and should not be considered as specific limitations thereof. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention. Process parameters not specifically specified in the following embodiments are generally performed under conventional conditions. The endpoints and any values ​​of the ranges disclosed in this invention are not limited to the precise ranges or values, and these ranges or values ​​should be understood to include values ​​close to these ranges or values. For numerical ranges, the endpoint values ​​of the various ranges, the endpoint values ​​of the various ranges and individual point values, and individual point values ​​can be combined with each other to obtain one or more new numerical ranges, which should be considered as specifically disclosed in this invention. Three-dimensional embroidery components, due to their unique three-dimensional visual effect and tactile feel, have wide applications in clothing decoration, home furnishings, and artworks. By selecting different patterns and material combinations, various realistic three-dimensional patterns can be created, such as floral patterns (roses, large plum blossoms), letters (ABC, etc.), and animal patterns. The following examples, in conjunction with the accompanying drawings, illustrate the preparation of a large plum blossom three-dimensional embroidery with high durability and structural stability.

[0029] Example 1 like Figures 1 to 5 , Figure 7 As shown in the embodiments of this application, a method for preparing a three-dimensional embroidery component is provided, the specific steps of which are as follows: S1: Constructing the superimposed structure Water-soluble paper with a weight of 60 g / m² is selected as the soluble auxiliary material layer and is flatly clamped in the embroidery frame of the computer embroidery machine as the bottom layer; a layer of woven fabric (as the shaping base fabric, with a heat shrinkage rate of <5% at 180℃) is then covered on top, and the edges of the pre-set large plum blossom pattern outline on the woven fabric are embroidered using a lock-edge method, such as... Figure 1 As shown, this is to prevent it from shifting or wrinkling during subsequent processing;

[0030] S2: Three-layer overlapping shaping embroidery and cutting A layer of 190T polyester taffeta (as a heat-shrinkable fabric with a heat shrinkage rate >15% at 180℃) is then layered on top of the woven fabric, forming a three-layered structure consisting of water-soluble paper, woven fabric, and polyester taffeta. The polyester taffeta is then placed over the fixed woven fabric, and the edges of the pre-designed large plum blossom pattern are embroidered again to define the shape. Figure 2 As shown; after completing the double-layer shaping embroidery, use a laser cutting device to precisely cut along the outer edge of the large plum blossom pattern, removing the excess parts of each layer that exceed the preset large plum blossom outline, to ensure that the outlines of the three layers of material are consistent and the edges are neat.

[0031] S3: Fixed Embroidery Overall The cut, three-layered structure is then subjected to full-width flat embroidery or grid-like fixed embroidery that runs through each layer, such as... Figure 3 As shown, this ensures a firm bond between the water-soluble paper, woven fabric, and polyester taffeta, preventing interlayer slippage during subsequent pattern embroidery or heat setting.

[0032] S4: Pattern Embroidery On the overall fixed layer, ordinary polyester embroidery thread is used to outline the petals and leaf veins with flat embroidery, and water-soluble embroidery thread is used to fill in the inner areas of the petals to form the designed pattern, such as... Figure 4 As shown. The water-soluble embroidery thread will be removed in a subsequent dissolving step, thus forming a hollow or embossed support structure.

[0033] S5: Dissolution treatment Immerse the completed embroidery components in 95°C hot water for 15 minutes to completely dissolve the water-soluble paper backing and water-soluble embroidery thread, leaving only the preliminary three-dimensional embroidery components composed of woven fabric, polyester taffeta, and non-water-soluble embroidery thread. Figure 5 As shown.

[0034] S6: Thermosetting The preliminary three-dimensional embroidery components were placed in an aluminum molding mold and heat-set at 200℃ with a working pressure of 1000 kPa for 19 seconds. During this process, polyester taffeta shrank significantly due to heat, while woven fabric shrank almost no. This difference in heat shrinkage properties caused the petal edges to arch upwards, as... Figure 7 As shown, the final result is a 3D stereoscopic visual effect with clear edges, distinct layers, and a strong sense of depth on one side.

[0035] Tests showed that the obtained three-dimensional embroidered components maintained a three-dimensional shape retention rate of ≥90% after 30 days of outdoor exposure and alternating hot and cold cycles, as well as 6,000 mechanical presses at 40 times per minute, demonstrating excellent durability and structural stability.

[0036] Example 2 like Figure 1 , Figures 3-6 This embodiment provides a method for preparing embroidery patterns with a slight three-dimensional raised or near-flat 3D visual effect, which is suitable for application scenarios that require moderate three-dimensionality but emphasize clear outlines and production efficiency (such as brand logos, geometric patterns, etc.).

[0037] S1: Construct a double-layered composite structure Water-soluble nonwoven fabric (50 g / m²) is selected as the soluble auxiliary material layer and is flattened and clamped in the embroidery frame of the computer embroidery machine as the bottom layer; a layer of high-density polyester fabric (as the shaping base fabric, with a heat shrinkage rate of <4% at 190℃) is covered on top to form a double-layer composite structure composed of water-soluble nonwoven fabric / high-density polyester fabric.

[0038] S2: Edge shaping embroidery and cutting Embroidery is applied to the edges of a pre-designed large plum blossom pattern on a high-density polyester fabric, such as... Figure 1 As shown, the fabric is fixed in shape and prevented from curling during processing; then, an ultrasonic cutting device is used to precisely trim along the embroidery outline, removing excess fabric that exceeds the pattern range, resulting in a double-layer structure with sealed edges and precise outline.

[0039] S3: Fixed Embroidery Overall like Figure 3As shown, the cut double-layer structure is embroidered with a grid pattern to firmly bond the base fabric and the water-soluble auxiliary material layer, ensuring that no relative displacement occurs during subsequent embroidery.

[0040] S4: Pattern Embroidery like Figure 4 As shown, on the basis of the overall fixed layer, ordinary polyester embroidery thread is used to perform flat embroidery to outline a large plum blossom pattern; at the same time, water-soluble embroidery thread is used to perform dotted filling embroidery in local areas inside the letters, so as to form a micro-hollow texture after dissolving, enhancing the visual sense of layering.

[0041] S5: Dissolution treatment The completed embroidered components are immersed in 85°C hot water for 25 minutes to completely dissolve the water-soluble non-woven fabric and water-soluble embroidery thread, resulting in a preliminary three-dimensional embroidered component composed only of high-density polyester fabric and non-water-soluble embroidery thread, such as... Figure 5 As shown.

[0042] S6: Thermosetting The preliminary 3D embroidery components are placed in a high-temperature resistant aluminum molding mold and hot-pressed for 20 seconds at a working pressure of 800 kPa and a temperature of 190°C. Since no heat-shrinkable fabric is used, the 3D effect mainly relies on the structural rigidity of the molding base fabric itself or its interaction with the use of heat-shrinkable embroidery thread (e.g., modified polyester embroidery thread with a heat shrinkage rate of 3%~8% at 200°C). Under preset tension, the embroidered stitches undergo controllable shrinkage after heat treatment, working in synergy with the base fabric to ultimately create a slightly embossed or near-flat 3D visual effect with distinct tactile layers on one side, such as... Figure 6 As shown, the structure has high overall flatness and is flexible and conformable, making it particularly suitable for curved substrates, such as shoe uppers, bags, and automotive interiors.

[0043] Tests showed that the 3D embroidered component did not detach or collapse under repeated bending, friction, and regular washing conditions, and maintained good appearance consistency, meeting the needs of high-frequency use scenarios such as bags and clothing labels.

[0044] In the above embodiments one and two, the heat setting temperature can be selected from any one of 160℃, 170℃, 180℃, 190℃, 200℃, 210℃, 220℃ or 230℃; the heat setting working time can be selected from 10 seconds, 15 seconds, 19 seconds, 21 seconds, 23 seconds, 25 seconds, 28 seconds or 30 seconds; the heat setting working pressure range can be selected from 800kPa, 830kPa, 860kPa, 900kPa, 920kPa, 950kPa, 980kPa and 1000kPa.

[0045] Example 3 like Figures 6-10As shown, in Example 3, the durability and stability of the three-dimensional embroidery component made from Example 1 (three-layer structure) were tested to verify its reliability as an independent functional component.

[0046] The three-dimensional embroidered component is a large plum blossom pattern with a diameter of 80 mm, featuring a distinct arched petal structure and a maximum protrusion height of approximately 9 mm. The following tests were performed on this component: 1. Environmental aging test: Placed in an outdoor natural environment for 30 consecutive days of exposure to sunlight, during which the daytime high temperature was 45℃, the nighttime low temperature was 15℃, and multiple rainfalls occurred; 2. Mechanical durability testing: such as Figures 8-10 As shown, a reciprocating pressing device was used to apply 5 N of pressure to the central area of ​​the component at a frequency of 40 times / minute, for a total of 58,099 presses. 3. Morphological preservation assessment: The height change of key points was measured using a 3D scanner before and after the test.

[0047] Test results: After being exposed to direct sunlight, the components showed no fading, brittleness, or collapse, and the petal arch height retention rate was ≥92%. After 58,099 presses, the three-dimensional outline remained clear, with a maximum height decrease of ≤8%, and no delamination or thread breakage. The components are soft and bendable, and can conform to surfaces with a curvature radius ≥20 mm without breaking. The three-dimensional embroidery components obtained by this invention possess excellent structural stability, environmental adaptability, and mechanical durability.

[0048] Example 4 This embodiment applies the above-mentioned three-dimensional embroidery components to a variety of end textile products, demonstrating their industrialization value and adaptability.

[0049] 1. Clothing Application: The three-dimensional rose embroidery component obtained in Example 1 was sewn onto the left chest area of ​​a woman's dress. The component fits the fabric perfectly and retains its three-dimensional shape without wrinkling or peeling after 15 washes (40℃ regular machine wash). 2. Application in bags: Geometric pattern 3D embroidered components (obtained from Example 2) are heat-pressed onto the front of a PU handbag. After 3 months of daily carrying, rubbing, and folding storage, the edges of the pattern show no wear, and the 3D effect remains distinct. 3. Automotive Interior Application: The brand logo 3D embroidered components are embedded in the headrest fabric of car seats. Under temperature cycling from -20℃ to 70℃ and high-frequency contact, the components show no deformation or odor release, meeting the requirements for automotive-grade decorative parts; 4. Footwear and home textiles: Used for sports shoe tongue labels, baseball cap front panels, and cushion surfaces, respectively, all exhibiting good flexibility, aesthetics, and durability.

[0050] The above applications demonstrate that the three-dimensional embroidery components of the present invention can be seamlessly integrated into various textile products, significantly enhancing the visual quality and added value of the products while meeting the functional requirements in actual use.

[0051] The above descriptions are merely some embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
