Description

Technical Field

[0001] The invention relates to the technical field of textiles, and in particular to a method for transferring a knitted texture of a cloth based on UV printing. Background Art

[0002] In the textile accessories industry, knitted fabric textures are highly favored for their unique texture and visual effects. However, there are many challenges in the production and application of traditional knitted fabric textures. First, the elastic deformation of the fabric itself makes positioning difficult and it is difficult to ensure the accuracy and consistency of the texture. Secondly, the gaps and holes between the longitude and latitude of the fabric, as well as the voids in the knitted yarn of the fabric and the hydrophilicity of the material itself make it difficult to implement the traditional direct rubbing method. During the direct rubbing process, the medium often gets stuck in the fibers and gaps, making it impossible to demold and separate, and may even pull off the textile thread fibers, thus affecting the quality and effect of the texture.

[0003] In addition, in traditional processes, the texture of textile threads in various weaves is usually printed on a mold or template through laser and mechanical processing. The texture produced by this method is often an imitation and cannot fully restore the authenticity and details of the knitted texture of the fabric. At the same time, this method is costly and requires multiple proofing. There is a large difference between the texture produced each time and the sample, which makes it difficult to meet customer expectations and needs. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a method for transferring knitted texture of cloth based on UV printing, which solves the problems raised by the above-mentioned background technology.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: A method for transferring fabric knitted texture based on UV printing, comprising the following steps: S1. Attach the adhesive positioning paper to the front of the textile fabric with fabric texture for positioning to prevent deformation in subsequent processes; S2. On the back of the textile fabric, hot-melt adhesive is bonded to the cardboard using a hot-pressing roller bonding device, and after cooling, the adhesive positioning paper is torn off, and then vacuum plating is performed to form a nano-scale electroplating layer on the surface of the textile fabric; S3, placing the electroplated textile fabric on the UV transfer equipment platform and fixing it, dripping UV glue and covering it with antistatic PTE film, evenly squeezing the UV glue through the roller of the UV transfer equipment, and curing the UV glue with the UV curing lamp behind the roller, and after curing, the UV glue adheres to the antistatic PTE film, and the antistatic PTE film is separated, at this time, the fabric texture of the textile fabric will be printed on the antistatic PTE film; S4, using a coating device to coat the expansion material on the antistatic PTE film with the cloth texture printed on it, and transferring the cloth texture from the antistatic PTE film to the expansion material through a lamination process; S5. Tear off the antistatic PTE film, so that the fabric texture on the textured textile fabric remains intact on the expansion material, completing the transfer of the fabric knitted texture.

[0006] Furthermore, the adhesive positioning paper is preferably an adhesive PET protective film.

[0007] Furthermore, after hot melt adhesive is applied to the back of the textile fabric, a nano-scale electroplating layer is formed on the surface of the textile fabric through vacuum electroplating to seal the fiber gaps of the textile fabric and prevent UV adhesive from penetrating.

[0008] Furthermore, the UV transfer device includes a roller and a UV curing lamp, the roller is used to evenly extrude the UV glue, and the UV curing lamp is used to cure the UV glue.

[0009] Furthermore, the antistatic PTE film is attached with a cloth texture after the UV glue is cured.

[0010] Furthermore, the expansion material is preferably any one of resin, silicone or TPU.

[0011] Furthermore, the pressing process is preferably any one of hot pressing, extrusion or rubbing.

[0012] Furthermore, the method for transferring the knitted texture of fabric based on UV printing also includes the steps of cleaning and drying the textile fabric after vacuum electroplating after step S2 to ensure the uniformity and adhesion of the electroplating layer.

[0013] Furthermore, the method for transferring the knitted texture of fabric based on UV printing also includes, after step S4, the step of trimming and inspecting the texture of the fabric coated with the expansion material to ensure the quality and appearance of the final product.

[0014] Furthermore, the method for transferring fabric knitted textures based on UV printing can achieve efficient and accurate transfer of fabric knitted textures, and the transferred textures are of high quality, and are suitable for texture production of a variety of expansion materials.

[0015] The present invention provides a method for transferring fabric knitted texture based on UV printing. Compared with the prior art, it has the following beneficial effects: 1. This method uses UV printing technology to directly print the required pattern on the product surface through computer control software, achieving efficient and accurate transfer of fabric knitted texture. This avoids the positioning difficulties and texture inconsistency caused by elastic deformation of fabric and fiber gaps in traditional methods; 2. The UV printing technology of this method has the characteristics of immediate drying, no blurring of patterns, wear resistance, and UV protection. Therefore, the present invention can produce high-quality, detailed fabric knitted textures. This meets the customer's needs for texture realism and detail restoration; 3. This method is not limited by materials and can be used for color photo-level printing on the surface of a variety of materials. Therefore, this method is suitable for the texture production of a variety of expanded materials and has broad application prospects; 4. Compared with the traditional method which requires multiple proofing and high costs such as laser and mechanical processing, the present invention uses UV printing technology to complete the production and transfer of textures at one time, greatly reducing the cost and time cost; 5. This method can be customized according to customer needs and preferences to produce a unique fabric knitting texture, which increases the added value and market competitiveness of the product.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Embodiment 1

[0019] See also Figure 1 ,The present invention provides a technical solution: a method for transferring fabric knitted texture based on UV printing; S1. First, we prepare a textile fabric 2 with a fabric texture 21 and a positioning paper with adhesive 1, wherein the positioning paper with adhesive 1 is preferably a sticky PET protective film to ensure good fit and positioning accuracy. The positioning paper with adhesive 1 is attached to the front of the textile fabric 2 to position and prevent deformation in subsequent processes; S2. Next, we use a hot-pressing roller laminating device to laminat e the hot melt adhesive 3 onto the cardboard 4 on the back of the textile fabric 2. After the hot melt adhesive 3 cools down, we tear off the adhesive positioning paper 1, and then perform vacuum electroplating on the textile fabric 2 to form a nano-scale electroplating layer on its surface. The purpose of this step is to seal the fiber gaps of the textile fabric 2 to prevent the subsequent penetration of UV adhesive 5; S3. Then, we place the electroplated textile fabric 2 on the platform of the UV transfer equipment and fix it. Then, add an appropriate amount of UV glue 5 and cover it with the antistatic PTE film 6. The UV glue 5 is evenly squeezed by the roller 7 of the UV transfer equipment, and the UV curing lamp 8 behind the roller 7 cures the UV glue 5. After curing, the UV glue 5 adheres to the antistatic PTE film 6. We separate the antistatic PTE film 6, and at this time, the fabric texture 21 of the textile fabric 2 will be printed on the antistatic PTE film 6; S4. Next, we use a coating device to coat the expansion material 9 on the antistatic PTE film 6 on which the cloth texture 21 is printed. In this embodiment, the expansion material 9 is preferably a resin. The cloth texture 21 is transferred from the antistatic PTE film 6 to the expansion material 9 by lamination treatment, such as hot pressing; S5. Finally, we tear off the antistatic PTE film 6, so that the fabric texture 21 on the textured textile fabric 2 remains intact on the expansion material 9, thereby completing the transfer of the fabric knitted texture. Embodiment 2

[0020] Based on Example 1, this example adds two additional steps to improve product quality, specifically: First, after step S2, we clean and dry the vacuum plated textile fabric 2. This step ensures the uniformity and adhesion of the electroplated layer, thereby improving the effect of subsequent UV transfer.

[0021] Secondly, after step S4, we trim and inspect the texture of the cloth coated with the expansion material 9. The excess expansion material and uneven parts are removed by trimming, and the quality and appearance of the final product are ensured to meet the requirements by inspection.

[0022] Through the description of Example 1 and Example 2, the method for transferring fabric knitted texture based on UV printing provided by the present invention can realize efficient and accurate transfer of fabric knitted texture. At the same time, by optimizing the adhesive positioning paper 1, the expansion material 9 and the pressing treatment method, the quality and applicability of the transferred texture can be further improved.

[0023] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
