Description

Technical Field

[0001] The present invention relates to the field of label processing, and more specifically, to a processing technology of an anti-counterfeiting woven label. Background Art

[0002] Woven labels are cloth labels containing text, letters, and LOGO patterns. They are used by clothing factories, garment factories, and home textile factories when they produce, manufacture, process, or sell clothing and home textiles. They are used to distinguish the sources of clothing and home textiles. They are marked with distinctive features consisting of text, graphics, letters, numbers, three-dimensional signs, color combinations, or a combination of the above elements.

[0003] The existing woven labels have a relatively simple function, which can only serve as identification and remind users of the washing method of fabrics. They are very easy to be counterfeited, resulting in consumers being unable to distinguish the authenticity of the goods by woven labels, causing consumers to purchase counterfeit products and suffer unnecessary economic losses. Therefore, there is an urgent need to prepare a new woven label with better anti-counterfeiting effect. Summary of the invention

[0004] In order to prepare a woven label with good anti-counterfeiting effect, the present application provides a processing technology for an anti-counterfeiting woven label.

[0005] The present application provides a processing technology for anti-counterfeiting woven labels, which adopts the following technical solutions: A processing technology for anti-counterfeiting woven labels includes the following steps: S1, spraying the color-changing paint evenly on the surface of the base fabric body, forming a color-changing coating after drying, and obtaining a semi-finished product; S2. Spray transparent waterproof coating evenly on the surface of the semi-finished product, and then use a hollow corrugated mold to print on the surface of the transparent waterproof coating. After drying and demolding, the transparent waterproof coating forms a transparent waterproof layer to obtain a finished woven label.

[0006] By adopting the above technical solution, the lining layer is adhered to the surface of the base fabric body by utilizing the viscosity of the adhesive liquid, and then the color-changing effect of the color-changing paint is utilized to facilitate product verification and achieve anti-counterfeiting effect. In combination with the hollow corrugated effect on the surface of the transparent waterproof layer, anti-counterfeiting is further performed. Consumers can verify the product status based on the visual effect and the hand-touch corrugated effect, thereby making the woven label have a better anti-counterfeiting function.

[0007] Preferably, the base fabric body comprises a base fabric and a pattern, and the base fabric is made by spinning spandex fiber, polyester fiber and PTT fiber in a mass ratio of 1:0.5-1:0.2-0.5.

[0008] By adopting the above technical scheme, spandex fiber, low-temperature fiber and PTT fiber have good tensile effect and high flexibility after spinning treatment. In the process of bending the woven label and machine washing the woven label, it is not easy for the mark on the woven label to become lighter or detached; moreover, the pores after spinning are convenient for loading the adhesive liquid, and the high bonding effect of the adhesive liquid is combined to improve the bonding stability between the base fabric body and the lining fabric layer, so that the woven label is resistant to pulling and machine washing. After machine washing, the color-changing coating and the transparent waterproof layer are still stably attached to the surface, so that consumers can verify the anti-counterfeiting of the clothes for a long time, and it is not easy to have the limitation that they can only verify at the time of purchase and cannot verify the authenticity later.

[0009] Preferably, the color-changeable coating comprises the following raw materials: 70-100 parts of fatty acid modified epoxy resin, 25-35 parts of curing agent, 2-5 parts of fluorite, 5-10 parts of cross-linking agent, 2-5 parts of orpiment, 1-3 parts of defoaming agent, and 1-4 parts of dispersant.

[0010] By adopting the above technical scheme, the flexibility of fatty acid-modified epoxy resin is utilized in combination with a cross-linking agent and a compatibilizer to improve the cross-linking bonding stability of fluorite and orpiment in the color-changing coating, and the dispersing effect of the dispersant is combined to improve the dispersion uniformity of fluorite and orpiment. Fluorite can change color under the irradiation of a blue light laser pen. Consumers who have a blue light laser pen at home can directly irradiate to verify the authenticity, while orpiment can change color under friction conditions. Consumers can rub the woven label and observe the color change of orpiment, thereby achieving a multiple anti-counterfeiting identification effect.

[0011] Preferably, the fluorite is prepared from fluorite particles and methyl methacrylate in a mass ratio of 1:0.1-0.2.

[0012] By adopting the above technical scheme, methyl methacrylate is attached to the surface of fluorite particles by utilizing its good transparency, which does not easily block the contact between fluorite particles and blue light laser pen, thereby ensuring the transmission effect of blue light, so that the fluorite particles can change color and achieve anti-counterfeiting effect. At the same time, methyl methacrylate contains ester groups, which have a hydrophobic effect and can improve the waterproof effect of color-changing coatings, thereby ensuring the authenticity verification effect of fluorite and orpiment on products.

[0013] Preferably, the orpiment is prepared from orpiment particles, polycarbonate particles and polyvinyl alcohol solution in a mass ratio of 1:0.1-0.2:0.1-0.2.

[0014] By adopting the above technical scheme, the high strength and high toughness of polycarbonate are utilized, and the viscosity of polyvinyl alcohol solution is utilized to facilitate adhesion to the surface of orpiment particles. During the friction process, the polycarbonate particles can also indirectly polish the orpiment particles, thereby helping the orpiment particles to change color. The hydroxyl groups in the polyvinyl alcohol solution are utilized to facilitate cross-linking and bonding with fatty acid-modified epoxy resin, thereby ensuring the dispersion effect of orpiment in the color-changing coating, which helps to verify the authenticity of the product.

[0015] Preferably, the transparent waterproof coating contains the following raw materials in parts by weight: 80-110 parts of silicone resin, 1-3 parts of thickener, 10-20 parts of fiber material, 10-20 parts of filler, 1-3 parts of photoinitiator, 1-3 parts of leveling agent, 1-2 parts of defoaming agent, and 50-80 parts of water.

[0016] By adopting the above technical scheme, the good waterproof and water-isolating effects of silicone resin are combined with good impact resistance to ensure that the anti-counterfeiting effect of the corrugated protrusions and the color-changing coating on the woven label is not easily affected during machine washing; the viscosity of the thickener is combined to make the fiber material and the filler more stably bonded in the transparent waterproof protective layer. During the mold pressing and molding process, the fiber material plays the role of a connecting bridge. During the mechanical process, the corrugated protrusions are not easy to be washed off, thereby ensuring that the authenticity of the finished product can still be verified after the fabric is machine washed many times, and has a long-term anti-counterfeiting effect; combined with the high strength of the fiber material and the filler, the shape of the corrugated protrusion is further guaranteed, and the problem of unclear corrugated lines is not easy to occur, ensuring that the authenticity of the finished product can be verified by hand touch, thereby achieving the effect of long-term anti-counterfeiting and machine-washing resistance of the woven label.

[0017] Preferably, the fiber material consists of polyacrylonitrile fiber and graphene fiber in a mass ratio of 1:0.1-0.2.

[0018] By adopting the above technical scheme, the high toughness of polyacrylonitrile fiber and graphene fiber is utilized, and the thermal conductivity of graphene fiber is matched. During the friction process, the friction temperature of the consumer's fingers is easily increased, further promoting the discoloration of orpiment, and the polyacrylonitrile fiber can ensure that the woven label recovers its shape after friction, so that the woven label itself is not prone to deformation problems while ensuring the anti-counterfeiting effect; at the same time, the polyacrylonitrile fiber and the graphene fiber act as a connecting bridge on the corrugation, ensuring the stability of the corrugation effect, and the existence of the corrugation is not easily affected by machine washing or friction, so that the authenticity of the woven label can still be verified after multiple machine washings or long-term use of the fabric, thereby extending the timeliness.

[0019] Preferably, the filler is composed of polycarbonate particles and boron nitride particles in a mass ratio of 1:0.2-0.5.

[0020] By adopting the above technical solution, the polycarbonate particles have good transparency and the polyacrylonitrile fibers have high flexibility, which further improves the toughness of the woven label and ensures that the woven label still has high stability and is not prone to deformation after multiple mechanical or friction operations. The thermal conductivity of the boron nitride particles and graphene fibers promotes the discoloration of orpiment during the friction process, thereby ensuring that the finished product can be verified for authenticity, and the verification method is relatively convenient.

[0021] Preferably, the hollow corrugated mold is made by spraying silicone oil on a hollow corrugated mold body.

[0022] Preferably, the silicone oil is one or more of hydroxy silicone oil, amino silicone oil and methyl silicone oil.

[0023] By adopting the above technical solution, after the surface of the hollow corrugated mold is loaded with silicone oil, the lubricating effect of the silicone oil is utilized to facilitate demoulding, thereby ensuring the molding effect of the woven label; and the hollow corrugated mold shape is convenient for air permeability, which promotes the room temperature curing effect of the transparent waterproof coating. On the other hand, it is convenient to form raised corrugations that are obviously felt by hand, which is convenient for verifying the authenticity of the finished woven label.

[0024] By adopting the above technical solution, In summary, this application has the following beneficial effects: 1. The color-changing effect of the color-changing paint is used to facilitate product verification and achieve anti-counterfeiting effect. The hollow corrugated effect on the surface of the transparent waterproof layer is used to further prevent counterfeiting. Consumers can verify the product based on the visual effect and the hand-touch corrugated effect, so that the woven label has a better anti-counterfeiting function.

[0025] 2. The flexibility of fatty acid-modified epoxy resin is used in combination with cross-linking agents and compatibilizers to improve the cross-linking and bonding stability of fluorite and orpiment in color-changing coatings. The dispersion effect of the dispersant is used to improve the dispersion uniformity of fluorite and orpiment. Fluorite can change color under the irradiation of a blue laser pen. Consumers who have a blue laser pen at home can directly irradiate to verify the authenticity, while orpiment can change color under friction conditions. Consumers can rub the woven label and observe the color change of orpiment, thereby achieving multiple anti-counterfeiting identification effects.

[0026] 3. The good waterproof and water-proof effects of silicone resin are combined with good impact resistance to ensure that the anti-counterfeiting effect of the corrugated convexity and the color-changing coating on the woven label is not easily affected during machine washing; the viscosity of the thickener is combined to make the fiber material and the filler more stably bonded in the transparent waterproof protective layer. During the mold pressing and molding process, the fiber material acts as a connecting bridge. During the mechanical process, the corrugated convexity is not easy to be washed off, thereby ensuring that the authenticity of the finished product can still be verified after the fabric is machine washed many times, and has a long-term anti-counterfeiting effect; combined with the high strength of the fiber material and the filler, the shape of the corrugated convexity is further guaranteed, and the problem of unclear corrugated lines is not easy to occur, ensuring that the authenticity of the finished product can be verified by hand touch, thereby achieving the effect of long-term anti-counterfeiting and machine-washing resistance of the woven label.

After drying at room temperature and removing the mold, the transparent waterproof coating forms a transparent waterproof layer to obtain a finished woven label.

[0043] Embodiment 3: This embodiment differs from Embodiment 1 in that: S1. The color-changing coating prepared in Preparation Example 6 is evenly sprayed on the surface of the base fabric prepared in Preparation Example 3, and 150 mL is evenly sprayed on the surface of the base fabric per square meter. After drying, the color-changing coating forms a color-changing coating to obtain a semi-finished product; S2.

After drying at room temperature and removing the mold, the transparent waterproof coating forms a transparent waterproof layer to obtain a finished woven label.

[0044] Embodiment 4: This embodiment differs from Embodiment 1 in that: In the color-changing paint, the fatty acid-modified epoxy resin is replaced by epoxy resin E51 of equal mass, and the curing agent is triethylenetetramine.

[0045] Embodiment 5: This embodiment differs from Embodiment 1 in that: No polycarbonate particles and polyvinyl alcohol solution are added during the preparation of orpiment in the color-changing paint.

[0046] Embodiment 6: This embodiment differs from Embodiment 1 in that: In color-changing paint, fluorite and orpiment are replaced with an equal amount of silicon dioxide.

[0047] Embodiment 7: This embodiment differs from Embodiment 1 in that: No fibers or fillers are added to the transparent waterproof coating.

[0048] Embodiment 8: This embodiment differs from Embodiment 1 in that: The fiber material in the transparent waterproof coating is glass fiber, and the average length of the glass fiber is 100 μm.

[0049] Embodiment 9: This embodiment differs from Embodiment 1 in that: The filler in the transparent waterproof coating is silicon dioxide particles, and the average particle size of the silicon dioxide particles is 80 μm.

[0050] Comparative Example Comparative Example 1: The difference between this comparative example and Example 1 is that: No color-changing coating is added during the preparation of woven labels.

[0051] Comparative Example 2: The difference between this comparative example and Example 1 is that: No transparent waterproof coating is added during the preparation of woven labels.

[0052] Performance testing 1. Anti-counterfeiting effect test Woven labels were prepared by the methods of Examples 1-3, 6 and Comparative Example 1, and irradiated with a blue laser pen (the blue laser pen was purchased from Li Bo (Shenzhen) Industrial Co., Ltd., M8X) for 10 minutes, and the color change was observed and the color change rating was recorded: 10 points for all color changes within the irradiation range → 0 points for no color change within the irradiation range; Woven labels were prepared by the methods of Examples 1-3, 5-6, 8-9 and Comparative Example 1, respectively, and rubbed by hand for 1 minute, then the color change was observed and the color change rating was recorded: 10 points for color change within the friction range → 0 points for no color change within the friction range.

[0053] Woven labels were prepared by the methods of Examples 1-3 and Comparative Example 2, respectively, and rubbed by hand for 30 seconds. The hand touch state was recorded. The special ripples could be clearly felt, indicating the presence of anti-counterfeiting marks.

[0054] 2. Washability test Woven labels were prepared by the methods of Examples 1-5, 7, 8 and Comparative Example 2, respectively, and washed in a Haier washing machine for 40 minutes, dried after washing, and repeated 10 times. Then, the discoloration was verified by a blue light laser pen again, and the discoloration area ratio was recorded, where the discoloration area ratio = the discoloration area irradiated by the blue light laser pen after washing the woven label / the discoloration area irradiated by the blue light laser pen before washing the woven label*100%; the larger the discoloration area ratio, the better the discoloration effect after washing, and the woven label can still have a good anti-counterfeiting effect after multiple washings.

[0055] Table 1 Performance test table (“ / ” in the table means that the corresponding embodiment or comparative example did not test the item, so there is no data) It can be seen from Examples 1-3 and Table 1 that the woven label prepared in the present application has a good anti-counterfeiting effect, can verify the authenticity of the product through blue light and friction detection, and has an obvious ripple feeling when touched, which is further convenient for authenticity verification. At the same time, after machine washing, it still has a color change effect when irradiated with blue light, indicating that the woven label can still verify the authenticity after machine washing, thereby improving the anti-counterfeiting effect of the woven label.

[0056] Combining Example 1 and Examples 4-9 and Table 1, it can be seen that in Example 4, the fatty acid-modified epoxy resin is replaced by epoxy resin E51 of equal mass in the color-changing paint, and the curing agent is triethylenetetramine. Compared with Example 1, the area ratio of the woven label prepared in Example 4 is smaller than that in Example 1; this indicates that the good flexibility of the fatty acid-modified epoxy resin after machine washing is utilized to protect the anti-counterfeiting effect of the color-changing paint, and the problem of orpiment and fluorite falling off is not likely to occur, thereby ensuring the anti-counterfeiting function of the woven label.

[0057] In the process of preparing orpiment in the color-changing coating of Example 5, no polycarbonate particles and polyvinyl alcohol solution were added. Compared with Example 1, the woven label prepared in Example 5 had a lower friction score than that in Example 1, and a smaller color change ratio than that in Example 1. This indicates that the polycarbonate particles can indirectly rub with the orpiment to promote the friction color change of the orpiment, while the polyvinyl alcohol can improve the bonding stability between the orpiment and the fatty acid-modified epoxy resin. After multiple machine washings, the orpiment is not easily peeled off, thereby ensuring that the woven label still has the anti-counterfeiting verification effect after machine washing.

[0058] In Example 6, fluorite and orpiment are replaced with an equal mass of silicon dioxide in the color-changing paint. Compared with Example 1, the woven label prepared in Example 6 cannot verify the authenticity of the product after blue light irradiation and friction treatment, indicating that the presence of orpiment and fluorite provides an anti-counterfeiting mark for the woven label.

[0059] No fiber material and filler are added to the transparent waterproof coating of Example 7. Compared with Example 1, the area of ​​the woven label prepared in Example 7 is smaller than that in Example 1. This shows that the addition of fiber material and filler can further improve the machine wash resistance of the transparent waterproof layer, ensuring that it still has a good anti-counterfeiting effect after machine washing.

[0060] The fiber material in the transparent waterproof coating of Example 8 is glass fiber. Compared with Example 1, the friction score of the woven label prepared in Example 8 is lower than that in Example 1, and the area ratio is smaller than that in Example 1. This shows that although the glass fiber has higher rigidity, it has no toughness and no frictional heat conduction function, so it is easy to affect the verification of the anti-counterfeiting effect.

[0061] The filler in the transparent waterproof coating of Example 9 is silica particles. Compared with Example 1, the friction score of the woven label prepared in Example 9 is lower than that in Example 1, and the area ratio is smaller than that in Example 1; this indicates that silica particles do not have a thermal conductivity effect, while boron nitride can conduct heat during friction, and silica particles have poor toughness, so the machine washing impact resistance effect deteriorates, which easily affects the anti-counterfeiting effect of the woven label.

[0062] Combining Example 1 and Comparative Examples 1-2 and Table 1, it can be seen that no color-changing coating is added during the preparation of the woven label in Comparative Example 1. Compared with Example 1, the score of the woven label prepared in Comparative Example 1 is lower than that in Example 1, indicating that the addition of the color-changing coating can make the woven label have an anti-counterfeiting effect.

[0063] No transparent waterproof coating was added during the preparation of the woven label in Comparative Example 2. Compared with Example 1, the woven label prepared in Comparative Example 2 had no ripple feeling when touched, and the area ratio was lower than that in Example 1; this indicates that the transparent waterproof layer on the surface of the woven label can not only ensure the anti-counterfeiting effect, but also enable the woven label to still have the advantage of anti-counterfeiting verification after multiple machine washings.

[0064] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make modifications to the present embodiment without any creative contribution as needed, but such modifications are protected by the patent law as long as they are within the scope of the claims of the present application.
