DETAILED DESCRIPTION

[0037] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with specific implementation methods.

[0038] Please refer to Figure 1-6 The present embodiment provides a method for manufacturing a double-sided holographic laser optical fabric 1, comprising the following steps:

[0039] Step S100: providing a set of molds, wherein the molds include a first mold 4 and a second mold 6 , wherein inner mold surfaces of the first mold 4 and the second mold 6 are both provided with a holographic laser texture structure 3 .

[0040] In this step, the first mold 4 and the second mold 6 are respectively provided with holographic laser texture structures 3 in a mirror image relationship with each other, and are respectively used to transfer the holographic laser texture structures 3 thereon to the upper surface and the lower surface of the UV resin 21 on the cloth 1. Through such molds, the holographic laser texture structures 3 on the first mold 4 and the second mold 6 can be transferred to the UV resin 21 of the cloth 1 by molding, so that the cloth 1 with a double-sided holographic laser texture structure 3 can be obtained. It can be understood that the first mold 4 and the second mold 6 are molds in a broad sense, which can be hard molds or flexible molds for film materials, and are not limited, and the transfer includes but is not limited to the direct embossing method or the film transfer method.

[0041] Step S200 : placing a mesh-shaped cloth 1 between the first mold 4 and the second mold 6 , wherein the cloth 1 is woven from transparent fiber threads 11 and has weaving gaps 12 .

[0042] In this step, the fabric 1 is woven fabric 1, so that it has a certain weaving gap 12. The weaving gap 12 can make the UV resin 21 fill the weaving gap 12 during the molding stage. After the UV resin 21 is cured, a resin layer 2 with high cross-linking properties can be obtained, and the UV resin 21 layer and the fabric 1 are not easy to peel off, and the durability is good. In addition, the transparent fiber filaments 11 can make the fabric 1 and the UV resin 21 form a whole with comparable transparency, thereby obtaining a better holographic visual effect.

[0043] Step S300: Coating UV resin 21 to the fabric 1, and molding the first mold 4 and the second mold 6 so that the UV resin 21 evenly fills the weaving gaps 12 of the fabric 1 and covers the upper and lower surfaces of at least a partial area of ​​the fabric 1, and the holographic laser texture structure 3 on the first mold 4 and the second mold 6 are respectively transferred to the upper and lower surfaces of the cured UV resin 21.

[0044] In this step, the UV resin 21 coated on the cloth 1 can generate structural crosslinking with the cloth 1 when the first mold 4 and the second mold 6 are overmolded, and can have a certain thickness on the upper and lower surfaces of the cloth 1, that is, covering a local area of ​​the cloth 1 or the upper and lower surfaces of the entire cloth 1, and by setting the holographic laser texture structure 3 on the upper and lower surfaces of the resin with a certain thickness, a double-sided holographic laser texture 31 can be obtained.

[0045] Step S400 : curing the UV resin 21 , wherein the refractive index of the cured UV resin 21 is consistent with the refractive index of the fiber filaments 11 of the cloth 1 .

[0046] In this step, the refractive index of the fiber filament 11 used is consistent with the refractive index of the UV resin 21, which can ensure the best optical effect during the propagation of light, and visually present a cloth 1 with high transparency and a stronger sense of unity, further improving the laser holographic colorful effect, making it more beautiful, and also increasing the difficulty of imitation.

[0047] Step S500: peeling off the first mold 4 and the second mold 6 to obtain the cloth 1 with the holographic laser texture structure 3.

[0048] In this step, after the first mold 4 and the second mold 6 are peeled off, the holographic laser texture structure 3 will remain on the resin on the cloth 1, and the cloth 1 with the holographic laser texture structure 3 can be obtained.

[0049] Through the above technical solution, the two molds provided with the holographic laser texture structure 3 can transfer the holographic laser texture structure 3 on the upper and lower surfaces of the resin on the cloth 1 by molding, so that the cloth 1 can obtain a two-sided holographic colorful effect, breaking the technical limitation of the existing technology that only has a single-sided holographic colorful effect, and the holographic colorful texture is formed by the resin passing through the cloth 1 and solidifying it, and the structure of the cloth 1 is wrapped and solidified inside, so that the holographic layer of such a holographic colorful cloth 1 has excellent adhesion on the cloth 1. At the same time, such a cloth 1 can significantly improve the transparency of the cloth 1 by configuring the resin layer 2 and the cloth 1 fiber with the same refractive index, so that it has the characteristics of high transparency, clearer and brighter, further improving the laser holographic colorful effect, more beautiful, and also increasing the difficulty of imitation.

[0050] In some embodiments, the fiber filaments 11 are silk or glass fiber filaments 11, the diameter of the fiber filaments 11 is 10-100 um, and the distance of the weaving gaps 12 is 5-200 um.

[0051] The fiber filaments 11 can be made of silk or glass fiber filaments 11, wherein silk is also a kind of fiber, which can be made transparent through existing processing methods to form silk with high transparency. The transparent fiber filaments 11 are woven by horizontal and vertical weaving methods. The diameter of the fiber filaments 11 used is 10-100um, and the distance of the weaving gap 12 is 5-200um. This data parameter range is obtained through a large number of experimental screenings, and by including parameters such as the diameter of the fiber filament 11 and the distance of the weaving gap 12, the best optical effect can be guaranteed and good coordination with other materials can be achieved.

[0052] Please refer to Figure 2-4 As shown, in one embodiment of the holographic laser texture structure, the holographic laser texture structure 3 is a holographic laser texture 31 engraved on the first mold 4 or the second mold 6, and the holographic laser texture 31 is transferred to the UV resin 21 of the cloth 1 by molding.

[0053] In this embodiment, the holographic laser texture 31 is pre-engraved on the first template and the second template, and the state of the holographic laser texture 31 on the first template and the second template is a concave texture state or a convex texture state, and the state is the opposite when transferred to the UV resin 21, and the holographic laser texture 31 of the first mold 4 and the holographic laser texture 31 of the second mold 6 are mirror images of each other. In this way, by molding the first template and the second template, the holographic laser texture 31 thereon can be transferred to the upper surface and the lower surface of the UV resin 21, which is more convenient and quick.

[0054] Please refer to Figure 5 and Figure 6As shown, in another embodiment of the holographic laser texture structure, the holographic laser texture structure 3 includes a cold stamping film for transfer printing on the UV resin 21, the cold stamping film includes an optical pattern layer 33 and an adhesive layer 32 sequentially arranged on the first mold 4 or the second mold 6, the optical pattern layer 33 has a holographic laser texture 31, and the optical pattern layer 33 is connected to the first mold 4 or the second mold 6 through a release film layer 400;

[0055] Based on the holographic laser texture structure 3 of the above embodiment, the adopted step S500 includes the following steps:

[0056] Step S510 : peeling off the first mold 4 and the second mold 6 in sequence, separating the cold stamping films on the first mold 4 and the second mold 6 from the release film layer 400 , and the separated cold stamping films are transferred to the UV resin 21 of the fabric 1 through the adhesive layer 32 .

[0057] Cold stamping films are provided on both the first template and the second template, and the optical pattern layer 33 of the cold stamping films can be adhered to the surface of the UV resin 21 through the adhesive layer 32 of the surface layer, and the first mold 4 and the second mold 6 can be separated from the optical pattern layer 33 through the release film layer 400, so that the optical pattern layer 33 with the holographic laser texture 31 can be transferred to the UV resin 21 through the transferable cold stamping film and can also be peeled off, thereby obtaining the fabric 1 with the double-sided holographic laser texture 31. In such a mold structure, the first template and the second template are the base layer, which can be a plate material or a film material.

[0058] Preferably, the first mold 4 and the second mold 6 are both substrate layers 300 made of PET material, and the cold stamping film is connected to the substrate through a release film layer 400. By using a substrate layer 300 such as PET material as the optical pattern layer 33, it can be better connected to other film layers. In this way, the composite layer mainly composed of the substrate layer 300, the release film layer 400, the optical pattern layer 33 and the adhesive layer 32 can be formed into a PET cold stamping optical film. For ease of explanation, the first mold 4 and each film layer thereon are used as the first PET cold stamping optical film 100, and the second mold 6 and each film layer thereon are used as the second PET cold stamping optical film 200, and are used as a whole for production when not separated.

[0059] Specifically, the optical pattern layer 33 may include a molded coating layer (not shown in the figure), a holographic laser texture 31 layer (not shown in the figure) and a surface film layer (not shown in the figure) which are arranged in sequence. The surface film layer can protect the holographic laser texture 31 layer, and the molded coating layer can facilitate the connection between the holographic laser texture 31 layer and the release layer.

[0060] In the specific implementation process, the manufacturing method of the embodiment of the present application also includes:

[0061] Step S600: removing the uncured UV resin 21 from the cloth 1 having the holographic laser texture structure 3 by dissolving a solvent, thereby obtaining a double-sided holographic laser optical cloth 1 having UV resin 21 of a target size.

[0062] In this step, there are usually requirements for the size of the resin area for making the holographic laser texture structure 3. During curing, it is targeted and selectively cured, and the uncured part needs to be removed. The uncured UV resin 21 can be removed by a dissolving solvent. The dissolving solvent can be alcohol, acetone, butanone and other ketone solvents, and it can also be an ester solvent and an aromatic hydrocarbon solvent. The excess uncured UV resin 21 can be washed away by these dissolving solvents.

[0063] Please refer to Figure 4 and Figure 6 As shown, in the embodiment of the present application, in step S300, the UV resin 21 is molded to uniformly fill the knitting gap 12 of the cloth 1 and cover the upper surface and the lower surface of at least a partial area of ​​the cloth 1 by molding the first mold 4 and the second mold 6, including the following method:

[0064] Step S310: Place the mask 7 on the first template or the second template located above, and apply pressure to the mask 7 through the roller 8 at a pressure of 0.2-0.4 MPa at a speed of 4-6 m / min, so that the UV resin 21 with a viscosity of 900-1100 mpa.s before curing evenly fills the weaving gaps 12 of the cloth 1 and covers the upper and lower surfaces of at least a partial area of ​​the cloth 1.

[0065] The mask 7 can be used for shielding UV curing and also as a pressure plate. The mask 7 can be pressed by a pressure device such as a roller 8, which can indirectly pressurize the first mold 4 and the second mold 6. The UV resin 21 with a viscosity of 900-1100mpa.s before curing is pressed by the roller 8 at a pressure of 0.2-0.4MPa and a speed of 4-6m / min to the mask 7, so that the UV resin 21 can be more effectively and evenly filled in the weaving gap 12 of the cloth 1. The above pressure and speed parameters are obtained through multiple experimental optimizations, which can ensure that the UV resin fully fills the grooves and gaps, and can avoid damage to the mold, the cloth 1 and the resin itself due to excessive pressure or too fast speed. The UV resin 21 has good tensile properties and toughness after curing.

[0066] Furthermore, in step S400, the UV resin 21 is cured, including the following method:

[0067] In step S410: using a mask 7 for shielding, the mask 7 has a shielding area for shielding ultraviolet light and a hollow area for ultraviolet light to pass through, and the area of ​​the hollow area is the same as the area of ​​the UV resin 21 of the target size;

[0068] In step S420 : the UV resin 21 is cured by the ultraviolet light curing device 9 .

[0069] The mask 7 has a shielding area for shielding ultraviolet light and a hollow area for ultraviolet light to pass through, and the area of ​​the hollow area is the same as the area of ​​the target curing area of ​​the UV resin 21 on the cloth 1. The mask 7 can shield the unnecessary resin area during the ultraviolet curing molding of the UV resin 21, thereby facilitating the acquisition of the UV resin 21 of the target shape or size. The ultraviolet curing device 9 can output ultraviolet light, and the UV resin 21 can be cured by irradiation with ultraviolet light.

[0070] Preferably, the ultraviolet light band used by the ultraviolet light curing device 9 for curing is 395 nm. The selection of this band is based on the light curing characteristics of the UV resin 21. The ultraviolet light of this band can most effectively stimulate the UV resin 21 to undergo a curing reaction, ensuring the consistency and stability of the curing effect.

[0071] Through the above-mentioned production mold and production method, a one-time double-sided holographic texture can be produced on a specific cloth 1. This is achieved based on the above-mentioned double-sided positioning mold and corresponding production process. By setting molds on both sides of the cloth 1 at the same time and performing synchronous production operations, the limitation of the prior art that only single-sided production can be performed is broken.

[0072] Since the holographic colorful texture on the cloth 1 of the embodiment of the present application is formed by the resin penetrating through the cloth 1 and solidifying, the structure of the cloth 1 is wrapped and solidified inside, so the holographic colorful cloth 1 manufactured according to the technical solution, the resin with the holographic laser texture structure 3 has excellent adhesion on the cloth 1. The specific principle is that during the manufacturing process, the UV resin 21 fills the gaps in the cloth 1 and solidifies under light, forming a structure that tightly combines the fibers of the cloth 1 with the holographic texture, so that the holographic layer is not easy to fall off from the cloth 1.

[0073] According to the manufacturing method of the technical solution, the refractive index of the UV resin 21 and the fabric 1 is consistent, so the holographic colorful fabric 1 has the characteristics of high transparency in addition to colorful holographic laser optics. Therefore, it will be clearer and brighter to watch the holographic laser colorful. The principle is that when the light passes through the fabric 1 and the cured resin, since the refractive index of the two is the same, no obvious refraction and reflection will occur during the propagation of the light, thereby ensuring the high transparency of the fabric 1 and the clear presentation of the holographic laser colorful effect.

[0074] Through the production mold and production method of the embodiment of the present application, the transparent gauze can be aligned with high precision on both sides, and the holographic laser colorful optical texture can be presented on both sides at one time. The holographic laser colorful cloth 11 produced by this method has the advantages of good viewing effect, wide application scenarios, low production cost, low production energy consumption, strong anti-counterfeiting strength, and is difficult to be removed from the cloth 1 for reuse.

[0075] The above are only preferred embodiments of the present invention. It should be noted that the above preferred embodiments should not be regarded as limiting the present invention, and the protection scope of the present invention should be based on the scope defined by the claims. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the spirit and scope of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
