Description
Technical Field
[0001] The utility model relates to the technical field of linen washing monitoring, in particular to an RFID washing label. Background Art
[0002] RFID radio frequency identification is a non-contact automatic identification technology. It automatically identifies the target object and obtains relevant data through radio frequency signals. The identification work does not require human intervention and can work in various harsh environments. Nowadays, RFID technology has achieved the ability to identify high-speed moving objects and multiple tags at the same time, which has greatly broadened the application of RFID electronic tags in various industries. RFID washing labels (also known as washing electronic tags) are the application products of RFID technology in the field of linen washing. Its function is to monitor and manage the entire life cycle of hotel linens, thereby improving the safety of hotel linens. Therefore, an important indicator for RFID washing labels is that they can withstand industrial washing and need to work normally after industrial washing.
[0003] At present, most of the RFID wash labels on the market cannot withstand the current industrial washing equipment (such as washing machines). This is mainly because the current industrial washing equipment not only produces a high-temperature and high-pressure washing environment, as well as a large torque rotation, which causes the RFID wash label to produce unexpected distortion during the washing process, but also exerts great mechanical pressure on the RFID wash label during the washing process. In particular, when the RFID wash label is subjected to the mechanical pressure while it is itself distorted, it will cause the RFID wash label to bend, thereby producing irreversible creases, causing the tag antenna at the crease to break or crack, thereby directly affecting or even destroying the performance of the RFID wash label. To this end, we propose an RFID wash label to solve the above problems. Utility Model Content

[0018] The design of the entire RFID care label provides all-round protection, including anti-interference, structural reinforcement and waterproof functions. This comprehensive protection enables the RFID care label to maintain normal operation in complex usage environments and significantly extends its service life;

[0029] The reinforcing layer 3 includes polyester fiber 301, nylon 302 and composite paper 303. The polyester fiber 301 is arranged on both sides of the RFID chip 1. The end faces of the polyester fibers 301 on both sides that are away from each other are compositely bonded with the nylon 302. The composite paper 303 is arranged on the side of the nylon 302 away from the polyester fiber 301. The polyester fiber 301, nylon 302 and composite paper 303 are arranged and distributed in sequence along the direction away from the RFID chip 1. The polyester fiber 301 is a lightweight and high-strength synthetic fiber, which is usually used to enhance the toughness and wear resistance of the material. It is arranged on both sides of the RFID chip 1, which can effectively enhance the overall structural strength of the washing label. High strength: The polyester fiber 301 itself has a very high tensile strength, which can effectively enhance the tensile properties of the washing label and reduce the possibility of damage. Compared with metal materials, the polyester fiber 301 is lighter and will not increase the weight of the washing label. At the same time, it provides good structural support. Nylon 302 is a wear-resistant and tensile-resistant synthetic material, which is used for the bonding effect on both sides of the reinforcing layer to increase the stability and durability of the structure. It has high wear resistance, which helps to increase the service life of the washing label, especially in scenarios where frequent friction is required. Nylon 302 has good adhesion to other materials and can effectively and firmly bond the various layers of materials together to increase the stability of the overall structure. Composite paper 303 is usually composed of paper and polymer, and has certain flexibility and water resistance. It is located close to the outside in the reinforcement layer 3, and plays a role in protecting the internal materials and increasing stability. It can provide flexibility to the reinforcement layer 3 to a certain extent, making the entire structure more resilient and durable. The polymer surface treatment of the composite paper 303 makes it have a certain waterproof property, which helps to protect the internal materials from moisture. Polyester fiber 301 provides high strength and light weight, which enhances the durability of the overall structure. Nylon 302 has wear resistance and good adhesion, which increases the stability of the structure, while the composite paper 303 provides flexibility and a certain waterproof property, which adds a protective effect to the function of the reinforcement layer 3. The combination of materials enables the reinforcement layer 3 to give full play to its structural reinforcement and protection functions.
[0030] The waterproof layer 4 specifically comprises silicone rubber 401, polyethylene film 402 and silicone coating 403. The silicone rubber 401 is arranged on both sides of the RFID chip 1. The silicone rubber 401 on both sides is symmetrically distributed along the axis of the RFID chip 1. The side of the silicone rubber 401 on both sides close to the RFID chip 1 is in contact with the composite paper 303, and the side of the silicone rubber 401 away from the composite paper 303 is in contact with the polyethylene film 402. The side of the polyethylene film 402 on both sides away from the silicone rubber 401 is in contact with the silicone coating 403. The silicone rubber 401, polyethylene film 402 and silicone coating 403 are arranged and distributed in sequence along the direction of the reinforcement layer 3 away from the RFID chip 1. The silicone rubber 401 has good flexibility and weather resistance, can fit tightly on both sides of the RFID chip 1, and provides good sealing performance. It can absorb and disperse the pressure from the outside to protect the internal RFID chip 1 from damage. The silicone rubber 401 has the characteristics of high temperature resistance, low temperature resistance, aging resistance and corrosion resistance, and can adapt to various harsh environmental conditions. At the same time, its flexibility enables it to adapt to RFID chips 1 of different shapes and provide good sealing performance. The polyethylene film 402, as the middle layer of the waterproof layer 4, plays the role of isolation and protection. It can prevent moisture and other liquids from penetrating into the RFID chip 1, and can also block the entry of dust and pollutants from the outside. The polyethylene film 402 has good chemical stability and wear resistance, and can resist the erosion of various chemical substances. It also has good flexibility and transparency, and will not affect the reading effect of the RFID chip 1. The silicone coating 403, as the outermost layer, provides the ultimate waterproof protection. It can form a hard protective film to prevent moisture and other liquids from penetrating into the interior. The silicone coating 403 has good weather resistance and wear resistance, and can maintain its performance for a long time. It also has good adhesion and flexibility, and can fit tightly on the polyethylene film 402 to provide a reliable waterproof effect. The combination of silicone rubber 401, polyethylene film 402 and silicone coating 403 forms a multi-layer waterproof layer 4, which can effectively protect the RFID chip 1 from the external environment. Each material has unique effects and advantages, and they work together to provide comprehensive waterproof protection.
