Description

Technical Field

[0001] This utility model is a hollow UV segmented embroidery, belonging to the textile field. Background Technology

[0002] In the field of textile decoration, traditional embroidery and printing techniques have been widely used in the production of various clothing, accessories and home furnishings. However, as consumers’ requirements for product appearance and texture continue to increase, traditional segmented embroidery has significant shortcomings in achieving multi-color gradient effects, because it mainly relies on the color of the embroidery thread itself to achieve the color effect of the pattern.

[0003] Relying on dyed embroidery thread to create delicate multi-color gradient effects is not only costly, but also has limited color accuracy. It is difficult to achieve the delicate color transitions and rich color variations that UV inkjet printing technology can. Furthermore, the production of dyed embroidery thread requires multiple complex processes, including dyeing, fixing, and cleaning. This not only increases production costs but may also lead to uneven color and color difference issues, making it difficult to meet the diverse and personalized color demands of modern consumers.

[0004] Furthermore, there are significant shortcomings in creating a sense of three-dimensionality and depth. While traditional UV printing can present certain patterns and textures, it lacks a clear sense of three-dimensionality and depth, making it difficult to meet consumers' pursuit of fashion and personalization. Although existing three-dimensional embroidery techniques can improve the three-dimensionality of patterns to a certain extent, there are still many problems in terms of production efficiency, pattern diversity, and post-processing. For example, some three-dimensional embroidery techniques require the use of special equipment and complex processes, resulting in high production costs and slow production speeds, making it difficult to meet the needs of large-scale production. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a hollow UV segmented embroidery to solve the technical problems of existing segmented embroidery relying on different dyed embroidery threads to achieve multi-color gradient effects and its lack of three-dimensionality and layering.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a hollow UV segmented embroidery, comprising:

[0007] A base fabric, which is used to provide a flat and stable surface;

[0008] A three-dimensional embroidery layer, comprising multiple support parts and multiple connecting parts, wherein the support parts are fixed to the top of the base fabric via the connecting parts;

[0009] A printing layer is applied directly to the top and / or sides of the support using UV printing technology, forming a three-dimensional graphic that matches the three-dimensional structure of the three-dimensional embroidery layer.

[0010] The three-dimensional embroidery layer is formed by embroidering a base fabric area with removable filler. After the embroidery is completed, the filler is removed through finishing, and the embroidery thread after removing the filler constitutes the three-dimensional embroidery layer.

[0011] Furthermore, the embroidery thread is a decorative embroidery thread with a specification of 100D-130D / 2.

[0012] Furthermore, the three-dimensional embroidery layer is fixed by the embroidery thread passing through the base fabric and intertwining with it to form a connecting part.

[0013] Furthermore, the stitch spacing of the three-dimensional embroidery layer ranges from 0.25mm to 0.55mm.

[0014] Furthermore, the base fabric is one of knitted fabric, woven fabric, cotton fabric, polyester fabric, or blended fabric.

[0015] Furthermore, the filler is expanding foam, and the thickness of the expanding foam is 1-6 mm.

[0016] Furthermore, the foaming adhesive is either polyurethane or synthetic rubber.

[0017] Furthermore, the three-dimensional embroidery layers are distributed continuously or at intervals.

[0018] Furthermore, the support portion is formed by multiple coils, the coil height ranging from 2 to 7 mm and the coil spacing ranging from 0.25 mm to 0.55 mm.

[0019] Furthermore, the printed layer partially covers the three-dimensional embroidery layer, and the printed layer covers 20%-85% of the surface area of ​​the support portion. The outermost edge of the printed layer is located within the boundary of the outermost embroidery thread of the support portion.

[0020] A method for preparing hollow UV segmented embroidery, the method comprising the following steps:

[0021] S1. Three-dimensional embroidery layer formation steps: Place the base fabric on the worktable of the hollow three-dimensional embroidery equipment. According to the preset pattern, first set the filling material on the base fabric and then embroider. So that the part of the embroidery thread that passes through the filling material during the embroidery process is higher than the base fabric to form a support part. And through the interweaving and wrapping of the embroidery thread and the base fabric, a connection part that is fixed to the base fabric is formed. After the embroidery is completed, the support material is removed through post-processing to form a hollow three-dimensional embroidery layer.

[0022] S2, Printing layer formation step: Place the fabric obtained in S1 on the worktable of the UV inkjet printing equipment, and perform UV inkjet printing on the three-dimensional surface of the three-dimensional embroidery layer according to the preset pattern to form a printing layer that matches the three-dimensional structure of the three-dimensional embroidery layer.

[0023] Furthermore, after the hollow UV segmented embroidery is prepared, it needs to be post-processed, which specifically includes: trimming and finishing, cleaning and drying, and ironing and shaping.

[0024] The beneficial effects of this utility model are:

[0025] This application uses UV inkjet printing technology to precisely print complex and intricate patterns, and combines it with hollow 3D embroidery technology to create fabrics with rich layers and a strong three-dimensional effect, thereby improving quality and market competitiveness.

[0026] The UV inkjet printing technology in this application can use a variety of primary colors to create rich colors. Combined with the unique texture of hollow three-dimensional embroidery, it significantly enhances the visual effect of the embroidery and creates a three-dimensional tactile feel with a raised or recessed effect, thereby enhancing the product's artistry and market appeal. Furthermore, it eliminates the need for traditional plate making, which can shorten the production cycle and improve efficiency.

[0027] This application reduces costs and material waste through the hollow design of the three-dimensional embroidery layer. At the same time, the UV inkjet printing technology saves dyes and chemicals, effectively reducing production costs and improving the market competitiveness of the product.

[0028] Therefore, by combining UV printing with hollow 3D embroidery, this application enables fabrics to have a unique three-dimensional effect and exquisite patterns, which not only improves product quality but also meets the market's demand for diversified and personalized products with its efficient production and customization capabilities, thereby enhancing market competitiveness.

[0037] [Hollow UV Segmentation Embroidery According to Embodiments of the Present Invention]

[0038] like Figure 1 As shown, this utility model provides a technical solution for hollow UV segmented embroidery, which includes:

[0039] Base fabric 1, which is used to provide a flat and stable surface;

[0040] The three-dimensional embroidery layer 2 includes multiple support parts 21 and multiple connecting parts 22. The support parts 21 are fixed to the top of the base fabric 1 through the connecting parts 22.

[0041] Printed layer 3, the printed layer 3 is directly covered on the top surface and / or side surface of the support part 21 by UV printing technology, forming a three-dimensional pattern that matches the three-dimensional structure of the three-dimensional embroidery layer 2.

[0042] The three-dimensional embroidery layer 2 is formed by setting fillers on the base fabric 1, embroidering in the area where fillers are set, and removing the fillers after finishing the embroidery. The embroidery thread after removing the fillers constitutes the three-dimensional embroidery layer 2.

[0043] In order to fix the three-dimensional embroidery layer and the base fabric, the three-dimensional embroidery layer 2 is embroidery thread. The embroidery thread passes through the base fabric 1 and intertwines with the base fabric 1 to form a connecting part 22, thereby achieving fixation.

[0044] To create a three-dimensional coating effect of the printed layer and the three-dimensional embroidery layer, the printed layer 3 is printed on the top surface and / or side surface of the support 21 using UV printing technology.

[0045] To provide stable support, the embroidery thread specification of the three-dimensional embroidery layer 2 is 100D-130D / 2.

[0046] To broaden its applicability, the base fabric 1 is one of knitted fabric, woven fabric, cotton fabric, polyester fabric, or blended fabric.

[0047] To improve the overall integrity, the stitch length of the three-dimensional embroidery layer is 0.25mm-0.55mm.

[0048] To enhance the three-dimensional effect, the filler is expanded foam with a thickness of 1-6mm.

[0049] To increase the stability of the three-dimensional embroidery layer, the foam is either polyurethane or synthetic rubber.

[0050] In order to form a continuous curved three-dimensional pattern, the three-dimensional embroidery layer 2 is distributed continuously or at intervals, and the support part 21 is formed by multiple coils. The height of the coils ranges from 2 to 7 mm, and the spacing between the coils ranges from 0.25 mm to 0.55 mm.

[0051] To highlight the local pattern, the printed layer 3 partially covers the three-dimensional embroidery layer 2, covering 20%-85% of the surface area of ​​the support part 21, and the outermost edge of the printed layer 3 is located within the boundary of the outermost embroidery line of the support part 21.

[0052] To achieve a 3D effect, the distance between the highest and lowest points of the 3D embroidery layer 2 is between 2mm and 7mm.

[0053] [Preparation method of hollow UV segmented embroidery according to embodiments of the present invention]

[0054] To facilitate manufacturing and save costs, this utility model also provides a method for preparing hollow UV segmented embroidery, the method comprising the following steps:

[0055] S1. Three-dimensional embroidery layer formation steps: Place the base fabric 1 on the worktable of the hollow three-dimensional embroidery equipment. According to the preset pattern, first set the filling material on the base fabric 1 and then embroider. So that the part of the embroidery thread that passes through the filling material during the embroidery process is higher than the base fabric 1 to form a support part 21. And through the interweaving and wrapping of the embroidery thread and the base fabric 1, a connection part 22 that is fixed to the base fabric 1 is formed. After the embroidery is completed, the support material is removed through post-processing to form a hollow three-dimensional embroidery layer 2.

[0056] S2, Printing layer formation step: Place the fabric obtained in S1 on the worktable of the UV inkjet printing equipment, and perform UV inkjet printing on the three-dimensional surface of the three-dimensional embroidery layer 2 according to the preset pattern to form a printing layer 3 that is compatible with the three-dimensional structure of the three-dimensional embroidery layer 2, thereby obtaining a hollow UV segmented embroidery product.

[0057] Once the hollow UV segmented embroidery product is prepared, it needs to undergo post-processing, which specifically includes: trimming and finishing, cleaning and drying, and ironing and shaping.

[0058] Example 1:

[0059] The preparation process of this application is as follows:

[0060] (1) Preparation of base fabric:

[0061] Select a base fabric 1 with appropriate thickness and size as needed, and lay the base fabric 1 flat on the worktable of the hollow 3D embroidery equipment. After ensuring that the surface is flat and wrinkle-free, install the filling material on it.

[0062] (2) Three-dimensional layered embroidery:

[0063] Using a hollow 3D embroidery machine, the embroidery speed and density are set in the machine. Embroidery thread is prepared according to the pattern and the thread diameter is set. After preparation, the 3D embroidery machine is controlled to embroider on the base fabric 1 according to the preset pattern data. During the embroidery process, the embroidery thread passes through the filler and forms a support part 21 on the base fabric 1. Then, the embroidery thread and the base fabric 1 are interwoven and wrapped to form a connection part 22 that is fixed to the base fabric 1. During the embroidery process, the machine will inject foam glue between the embroidery threads to form a 3D embroidery layer 2.

[0064] (3) Removal of expanding foam:

[0065] To remove the foam, first set the temperature, washing time, and dehydration time of the dry cleaning machine, then put the base fabric 1 with the three-dimensional embroidery layer 2 into the dry cleaning machine. During the washing process, the dry cleaning agent will penetrate into the foam, causing it to expand and loosen, and eventually be completely washed away.

[0066] (4) UV inkjet printing:

[0067] Lay the dry-cleaned base fabric 1 flat on the worktable of the UV inkjet printing equipment, adjust the printing thickness and speed, and print according to the preset pattern data. After printing, use a UV lamp to cure the printed layer 3.

[0068] (5) Post-processing:

[0069] To ensure the feel and performance of the fabric, this application can introduce a post-processing step for inspection after the fabric is prepared. The post-processing step includes trimming, washing and drying, ironing and shaping, and quality inspection.

[0070] Trimming and Finishing: Use scissors to trim excess threads and rough edges to ensure a clean product surface; Cleaning and Drying: Clean the product with a suitable cleaning agent to remove surface dust, stains, and residual chemicals, then dry it; Ironing and Shaping: Make the product surface smooth and even, while also helping to set the shape, ensuring the product's shape and size are stable; Quality Inspection: Conduct rigorous quality inspections on the finished fabric, including visual inspection, size measurement, and color matching, to ensure the fabric meets design requirements and quality standards. Products that do not meet the requirements are promptly reworked or processed.

[0071] After the above preparation process, a hollow UV segmented embroidery is obtained. The fabric has a high-layer three-dimensional embroidery layer 2 and a printing layer 3 with rich colors and exquisite patterns. The overall appearance has a strong three-dimensional and layered feel, and the texture is rich, which meets consumers' demand for high-quality embroidery.

[0072] Example 2:

[0073] In this embodiment, the height of the three-dimensional embroidery layer 2 on the same fabric is kept consistent. Three-dimensional embroidery layer 2 with a height of 3mm and three-dimensional embroidery layer 2 with a height of 5mm are prepared for comparison. During the preparation process, only the height of the foaming adhesive is adjusted, and the other settings remain unchanged.

[0074] By comparing fabrics with different heights of the three-dimensional embroidery layer 2: When the height of the three-dimensional embroidery layer 2 is 3mm, from a visual perspective, the three-dimensional effect it produces is more delicate and subtle, suitable for designs that emphasize details and refinement; in terms of touch, the 3mm three-dimensional embroidery layer 2 is more tightly bonded to the base fabric 1, and the overall surface is relatively flat; in terms of structural stability, the 3mm three-dimensional embroidery layer 2, due to its tight bond with the base fabric 1 and the moderate height of the foam, makes the overall structure more stable and less prone to loosening or deformation.

[0075] When the height of the 3D embroidery layer 2 increases to 5mm, its visual effect becomes more prominent, with a stronger sense of three-dimensionality and visual impact, allowing the patterns and colors to be displayed more fully. In terms of touch, the 5mm 3D embroidery layer 2 gives the fabric surface obvious undulations and layers, providing a rich and unique texture when touched. However, in terms of structural stability, due to the increased height of the 3D embroidery layer 2, the connection between it and the base fabric 1 is slightly inferior compared to the 3mm embroidery layer. Slight loosening may occur in some more delicate or complex patterns, but the overall structure can still remain relatively stable.

[0076] Example 3:

[0077] The difference between this embodiment and embodiment 2 is that this embodiment has three-dimensional embroidery layers 2 with varying heights in the same fabric. By controlling the amount of foaming adhesive in different areas, a variety of visual effects and tactile sensations are achieved.

[0078] Specifically, in some areas, the height of the three-dimensional embroidery layer can reach 5mm. The patterns in these areas can display a strong sense of three-dimensionality and visual impact. At the same time, when touched, you can feel obvious undulations and rich texture. In other areas, the height of the three-dimensional embroidery layer can be controlled at around 3mm. This treatment makes the background relatively low-key, which serves to highlight the main pattern elements. The overall visual effect is more layered and dynamic, making the pattern appear staggered.

[0079] Example 4:

[0080] like Figure 2 and Figure 3As shown, the three-dimensional embroidery layer 2 in this application is a wave shape composed of continuous curves. The wave-shaped three-dimensional embroidery layer 2 has smooth curves and natural undulations, which can create a dynamic and soft visual effect. Moreover, the undulations of the wave shape can produce rich light and shadow changes. With different light angles, the peaks and troughs of the waves will present different contrasts of light and dark, further enhancing the three-dimensionality and layering of the embroidery, making it more visually attractive and artistically appealing.

[0081] Example 5:

[0082] like Figure 4 and Figure 5 As shown, the three-dimensional embroidery layer 2 in this application is grid-shaped. The grid-shaped three-dimensional embroidery layer 2 has a strong sense of structure and modernity, and can bring a neat and orderly visual effect to the embroidery. The spacing of the grid and the thickness of the lines can be adjusted according to the design requirements to achieve different visual effects and tactile sensations.

[0083] Example 6:

[0084] The 3D embroidery layer 2 can also use other patterns, such as geometric patterns, abstract patterns, plant patterns or animal patterns. Through diverse pattern designs, it can meet the needs and preferences of different consumers and bring rich and diverse visual effects and artistic styles to the fabric.

[0085] Example 7:

[0086] In the UV printing process of this application, different pattern elements can be printed at different positions of the three-dimensional embroidery layer 2 by controlling the movement trajectory of the print head and the amount of UV adhesive sprayed. Especially in areas with large embroidery thread spacing, combined with the characteristics of the hollow structure, different patterns can be printed on the side and top surfaces respectively, thereby achieving a multi-dimensional pattern effect. For example, in one design, when viewed from the left, the light is refracted, and the pattern on the side is mainly seen; while when viewed from the right, the light shines directly on the top surface, presenting different pattern effects. This design makes full use of the hollow structure of the three-dimensional embroidery layer 2, so that the pattern presents a rich visual effect at different angles.

[0087] When this application uses three-dimensional embroidery layers 2 with varying heights, and the distance between the highest and lowest points of the three-dimensional embroidery layers is between 2mm and 7mm, it can be combined with height difference spraying to achieve richer three-dimensional effects and multi-dimensional pattern effects:

[0088] In areas with lower height (2mm-3mm): the three-dimensional effect is relatively weak and the flatness is strong. In these areas, some background patterns or auxiliary patterns can be printed to highlight the main pattern.

[0089] In areas of moderate height (4mm-5mm): the three-dimensional effect is more obvious in these areas, and some transitional or auxiliary patterns can be printed to increase the sense of layering and three-dimensionality of the pattern.

[0090] In areas with higher elevations (6mm-7mm): the three-dimensional effect is most pronounced in these areas, where the main pattern elements can be printed to highlight the key points and focal points of the design;

[0091] By combining this design with varying heights and UV printing technology, richer and more three-dimensional pattern effects can be achieved. The three-dimensional embroidery layers 2 of different heights will produce different refraction and reflection effects under light, so that the pattern presents different visual effects at different angles. That is, the lower the height, the worse the three-dimensional effect and the stronger the flatness; the higher the height, the better the three-dimensional effect, and a three-dimensional 3D effect can be achieved. On this basis, combined with the effect of refraction, not only can the product's sense of layering and three-dimensionality be increased, but the pattern can also present rich visual effects at different angles, enhancing the product's artistic value and visual appeal, thus meeting consumers' demand for high-quality and personalized embroidery products.

[0092] This application uses UV inkjet printing technology to precisely print complex and intricate patterns, and combines it with hollow 3D embroidery technology to create fabrics with rich layers and a strong three-dimensional effect, thereby improving quality and market competitiveness.

[0093] The UV inkjet printing technology in this application can use a variety of primary colors to create rich colors. Combined with the unique texture of hollow three-dimensional embroidery, it significantly enhances the visual effect of the embroidery and creates a three-dimensional tactile feel with a raised or recessed effect, thereby enhancing the product's artistry and market appeal. Furthermore, it eliminates the need for traditional plate making, which can shorten the production cycle and improve efficiency.

[0094] This application utilizes the hollow design of the three-dimensional embroidery layer 2 to reduce costs and material waste. Simultaneously, UV inkjet printing technology saves on dyes and chemicals, effectively lowering production costs and enhancing the product's market competitiveness.

[0095] Therefore, by combining UV printing with hollow 3D embroidery, this application enables fabrics to have a unique three-dimensional effect and exquisite patterns, which not only improves product quality but also meets the market's demand for diversified and personalized products with its efficient production and customization capabilities, thereby enhancing market competitiveness.
