[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 goods. However, with the increasing demand of consumers for product appearance and texture, traditional split embroidery has significant shortcomings in achieving multi-color gradient effects, as 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 form delicate multi-color gradient effects not only has high cost, but also has limited color accuracy, making it difficult to achieve delicate color transitions and rich color variations like UV spray printing technology. Moreover, the production of dyed embroidery thread requires a complex process flow, including dyeing, fixing, washing and other steps, which not only increases production costs, but also may cause color unevenness and color difference problems, making it difficult to meet the needs of modern consumers for diversified and personalized colors.

[0004] In addition, there are obvious shortcomings in forming a sense of three-dimensionality and hierarchy. Traditional UV printing can present certain patterns and textures, but it lacks obvious three-dimensionality and hierarchy, making it difficult to meet the pursuit of fashion and individuality by consumers. Existing three-dimensional embroidery techniques can improve the three-dimensionality of patterns to some extent, but still have many problems in production efficiency, pattern diversity and post-processing, such as the use of special equipment and complex processes, resulting in high production costs and slow production speed, making it difficult to meet the needs of mass production.

[0024] 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.

[0025] [Hollow UV Segmentation Embroidery According to Embodiments of the Present Invention] like Figure 1 As shown, the present invention provides a technical solution for hollow UV segmented embroidery, which includes: Base fabric 1, which is used to provide a flat and stable surface; 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. 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. 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.

[0026] 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.

[0027] 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.

[0028] To provide stable support, the embroidery thread specification of the three-dimensional embroidery layer 2 is 100D-130D / 2.

[0029] To broaden its applicability, the base fabric 1 is one of knitted fabric, woven fabric, cotton fabric, polyester fabric, or blended fabric.

[0030] To improve the overall integrity, the stitch length of the three-dimensional embroidery layer is 0.25mm-0.55mm.

[0031] To enhance the three-dimensional effect, the filler is expanded foam with a thickness of 1-6mm.

[0032] To increase the stability of the three-dimensional embroidery layer, the foam is either polyurethane or synthetic rubber.

[0033] 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.

[0034] In order to highlight the local pattern, the printing 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 side of the printing layer 3 is located within the boundary of the outermost embroidery line of the support part 21.

[0035] In order to achieve the 3D effect, the distance from the highest point to the lowest point of the three-dimensional embroidery layer 2 is between 2mm-7mm.

[0036] [Preparation method of hollow UV segmented embroidery according to the embodiment of the application] Referring to Figure 6 As shown in the figure, in order to facilitate manufacturing and save costs, the application also provides a preparation method of hollow UV segmented embroidery, which comprises the following steps: S1, three-dimensional embroidery layer forming step: placing the base cloth 1 on the workbench of the hollow three-dimensional embroidery equipment, first setting the filler on the base cloth 1 according to the preset pattern, then embroidering, so that the part of the embroidery thread passing through the filler during the embroidery process is higher than the base cloth 1 to form a support part 21, and the interweaving and winding of the embroidery thread and the base cloth 1 forms a connecting part 22 fixed with the base cloth 1, and after the embroidery is completed, the support part is removed through post-processing to form a hollow three-dimensional embroidery layer 2; S2, printing layer forming step: placing the fabric obtained in S1 on the workbench of the UV jet printing equipment, performing UV jet printing on the three-dimensional surface of the three-dimensional embroidery layer 2 according to the preset pattern, forming a printing layer 3 adapted to the three-dimensional structure of the three-dimensional embroidery layer 2, and obtaining a hollow UV segmented embroidery product.

[0037] When the hollow UV segmented embroidery product is prepared, it also needs to be post-processed, and the post-processing tool includes trimming and arranging, washing and drying, and ironing and shaping.

[0038] Example 1: The preparation process of the application is as follows: (1) Base cloth preparation: According to the needs, select the base cloth 1 with appropriate thickness and size, and lay the base cloth 1 on the workbench of the hollow three-dimensional embroidery equipment, ensure that the surface is flat and wrinkle-free, and then install the filler on it.

[0039] (2) Three-dimensional embroidery layer embroidery: Use the hollow three-dimensional embroidery equipment, set the embroidery speed and density in the equipment, prepare the embroidery thread according to the pattern and set the thread diameter, and after preparation, control the three-dimensional embroidery equipment to embroider on the base cloth 1 according to the preset pattern data, the embroidery thread passes through the filler during the embroidery process, and forms a support part 21 on the base cloth 1, and then forms a connecting part 22 fixed with the base cloth 1 through the interweaving and winding of the embroidery thread and the base cloth 1, wherein, during the embroidery process, the equipment will inject foaming glue between the embroidery threads to form a three-dimensional embroidery layer 2.

[0040] (3) Foam removal: The foam is removed using a dry cleaning machine. First, the temperature, washing time and dehydration time of the dry cleaning machine are set, and then the fabric 1 with the three-dimensional embroidery layer 2 is placed in the dry cleaning machine. During the washing process, the dry cleaning agent penetrates into the foam, causing it to swell and loosen, and eventually being completely washed away.

[0041] (4) UV printing: After dry cleaning, the fabric 1 is placed on the workbench of the UV printing equipment, the thickness and speed of the printing are adjusted, and the printing is performed according to the preset pattern data. After printing, the printed layer 3 is cured using a UV irradiation lamp.

[0042] (5) Post-processing: In order to ensure the hand feeling and performance of the fabric, the application can introduce a post-processing step for inspection after the fabric is prepared. The post-processing step includes trimming and arranging, washing and drying, ironing and shaping, and quality detection.

[0043] Trimming and arranging: using scissors to trim off excess threads and burrs to ensure the surface of the product is clean; washing and drying: using appropriate cleaning agents to clean the product, removing surface dust, stains and residual chemicals, and then drying; ironing and shaping: making the product surface smooth, which helps to shape and ensure the shape and size of the product is stable; quality detection: strictly detecting the completed fabric, including appearance inspection, size measurement, color matching, etc., to ensure that the fabric meets the design requirements and quality standards. For products that do not meet the requirements, timely rework or processing is performed.

[0044] After the above preparation process, a hollow UV divided embroidery is obtained. The fabric has a high-level three-dimensional embroidery layer 2, a rich and exquisite printed layer 3 with a strong three-dimensional and hierarchical appearance, and a rich touch, meeting the needs of consumers for high-quality embroidery.

[0045] Example 2: In this embodiment, the height of the three-dimensional embroidery layer 2 on the same fabric is kept consistent, and three-dimensional embroidery layers 2 with a height of 3 mm and three-dimensional embroidery layers 2 with a height of 5 mm are prepared for comparison. During the preparation process, only the height of the foam is adjusted, and the remaining settings remain unchanged.

[0046] By comparing the fabrics with different heights of the three-dimensional embroidery layer 2: when the height of the three-dimensional embroidery layer 2 is 3 mm, the visual effect is relatively delicate and restrained, which is suitable for designs that pay attention to details and delicacy; from the touch, the three-dimensional embroidery layer 2 with a height of 3 mm is combined with the base fabric 1 more closely, and the overall surface is relatively flat; in terms of structural stability, the three-dimensional embroidery layer 2 with a height of 3 mm is closely combined with the base fabric 1, and the height of the foaming glue is moderate, so that the overall structure is relatively stable and is not prone to loosening or deformation.

[0047] When the height of the three-dimensional embroidery layer 2 increases to 5 mm, it is more prominent in visual effect, with stronger three-dimensionality and visual impact, and the pattern and color can be fully displayed; from the touch, the three-dimensional embroidery layer 2 with a height of 5 mm makes the surface of the fabric have obvious undulations and levels, and when touched, a rich and unique texture can be felt, however, in terms of structural stability, due to the increase in the height of the three-dimensional embroidery layer 2, the connection between it and the base fabric 1 is relatively poor compared to the 3 mm high embroidery layer, and there may be slight loosening in some more delicate or complex pattern parts, but the overall structure can still remain relatively stable.

[0048] Example 3: The difference between this embodiment and Example 2 is that this embodiment has three-dimensional embroidery layers 2 with inconsistent heights in the same fabric, and by controlling the amount of foaming glue in different areas, various visual effects and textures are achieved.

[0049] Specifically, in some areas, the height of the three-dimensional embroidery layer can reach 5 mm, and the pattern in these areas can exhibit strong three-dimensionality and visual impact, and when touched, obvious undulations and rich texture can be felt, while in other areas, the height of the three-dimensional embroidery layer can be controlled to about 3 mm, which makes the background part relatively low-key, playing a role in highlighting the main pattern elements, and the overall visual effect has more levels and dynamics, making the pattern appear in a staggered manner.

[0050] Example 4: As shown in Figure 2 and Figure 3 , the three-dimensional embroidery layer 2 in this application is in the shape of a wave composed of continuous curves, and the wave-shaped three-dimensional embroidery layer 2 has smooth curves and natural undulations, which can create a dynamic and soft visual effect, and the undulations of the wave can produce rich light and shadow changes, with different light angles, the peaks and valleys of the wave will present different light and shade contrasts, further enhancing the three-dimensionality and levels of the embroidery, making it more visually attractive and artistically appealing.

[0051] Example 5: As shown in Figure 4 and Figure 5As 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.

[0052] Example 6: 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.

[0053] Example 7: 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.

[0054] 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: 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. 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. 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; Through the highly uneven design, combined with the UV jet printing technology, more rich and three-dimensional pattern effects can be realized, and different heights of the three-dimensional embroidery layer 2 will produce different refraction and reflection effects under light irradiation, 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 sense of flatness; the higher the height, the better the three-dimensional effect, so as to realize the three-dimensional 3D effect, on the basis of which, combined with the refraction effect, not only the sense of level and the sense of three-dimensionality of the product are increased, but also the pattern presents rich visual effects at different angles, the artistic value and visual attraction of the product are improved, so as to meet the needs of consumers for high-quality and personalized embroidery products.

[0055] The application adopts the UV jet printing technology to accurately jet print complex and fine patterns, and is combined with the hollow three-dimensional embroidery technology, so as to create a fabric with rich levels and strong three-dimensionality, and then improve the quality and market competitiveness.

[0056] The UV jet printing technology in the application can use various primary colors to mix rich colors, combined with the unique texture of the hollow three-dimensional embroidery, the visual effect and three-dimensional touch of the embroidery product producing concave-convex effect are significantly improved, the artistic nature and market attraction of the product are enhanced, and the product does not need traditional plate making, so as to shorten the production cycle and improve the efficiency.

[0057] The hollow design of the three-dimensional embroidery layer 2 in the application can reduce the cost and material waste, and the UV jet printing technology saves dyeing materials, effectively reduces the production cost, and improves the market competitiveness of the product Therefore, the application combines the UV jet printing and the hollow three-dimensional embroidery, so that the fabric has unique three-dimensional effect and exquisite pattern, not only improves the product quality, but also meets the market demand for diversified and personalized products by virtue of efficient production and customization capability, so as to enhance the market competitiveness.
