Abstract
Description
Technical Field
[0001] This utility model belongs to the field of trademark tape, and in particular relates to an RFID trademark tape. Background Technology
[0002] Existing RFID label tapes, such as the water-resistant RFID label tape with application number 202010483102.9, consist of a waterproof polyester base layer, a printing layer, a first adhesive layer, an RFID chip layer, a PET film layer, a second adhesive layer, and a release layer, from top to bottom. The method of using such label tapes is to peel off the release layer and attach it to the corresponding item. This item cannot be clothing, because label tapes on clothing require permanent fixation, and the adhesive method will not be firm after repeated washing. Therefore, it is generally fixed by sewing, which existing RFID label tapes cannot meet.
[0003] The aforementioned washable RFID label tape is actually a type of RFID electronic tag. Electronic tags can be fixed by adhesive, while label tape in the apparel industry serves as a carrier for brand and product information, requiring permanent fixation, typically achieved through sewing. Currently, although the apparel industry widely uses electronic tags attached to clothing packaging for convenient inventory and logistics transfer, once clothing is sold, customers quickly discard the outer packaging after using the garment, resulting in the loss of the electronic tag. This hinders rapid product traceability in after-sales service. Integrating electronic tags into the label tape to create a true RFID label tape would undoubtedly provide greater convenience for after-sales service, but such a product does not currently exist. Utility Model Content
[0004] The purpose of this invention is to provide an RFID tag. This invention has the advantages of being usable on clothing and having good performance.
[0005] The technical solution of this utility model is as follows: an RFID trademark strip, including an RFID chip layer, a first encapsulation layer and a sealing second encapsulation layer are sequentially provided on the outer side of the RFID chip layer, at least one end of the second encapsulation layer forms a sewing area, a fabric layer is provided between the first encapsulation layer and the second encapsulation layer, a portion of the fabric layer is located within the sewing area, and a printing layer is provided on the outer side of the fabric layer.
[0006] In the aforementioned RFID trademark strip, the RFID chip layer includes an RFID chip, an antenna is connected to the RFID chip, and the first encapsulation layer includes a bottom film located on the lower side of the RFID chip layer and a cover film located on the upper side of the RFID chip layer, with the antenna fixed to the bottom film.
[0007] In the aforementioned RFID trademark tape, both the base film and the coating are made of PET, with the base film thickness being 25-30μm and the coating thickness being 8-10μm.
[0008] In the aforementioned RFID trademark tape, the material of the second encapsulation layer is liquid silicone, and the RFID chip layer and the first encapsulation layer are sealed and wrapped inside the second encapsulation layer.
[0009] In the aforementioned RFID trademark tape, the thickness of the second encapsulation layer is less than 0.2 mm.
[0010] Compared with existing technologies, this utility model is designed specifically to meet the requirements of the garment industry for trademark tape. Firstly, a sewing area is reserved to avoid the RFID chip layer. This area allows the trademark tape to be sewn onto the garment, ensuring permanent fixation without damaging the RFID chip layer and maintaining good radio frequency functionality. This not only facilitates pre-sale inventory and logistics transfer but also provides convenience for after-sales service. Secondly, the trademark tape incorporates a fabric layer with good tear resistance. This layer serves as the stress-bearing connection between the trademark tape and the garment, further increasing the tape's fixation strength. The fabric layer also acts as a carrier for the printing layer. Because the printing ink can penetrate the fabric layer, the printing volume is larger, the color is deeper, and the printed layer is clearer, clearly reflecting the garment information and meeting relevant requirements of the garment industry. A sealed encapsulation layer makes the trademark tape waterproof, washable, and suitable for use on garments. Furthermore, the selection of materials for the encapsulation layer makes the trademark tape soft overall, ensuring good contact with the skin when fixed inside the garment, without any cutting sensation, resulting in better performance. Therefore, this utility model has the advantages of being usable on clothing and having a good effect. Attached Figure Description
[0011] Figure 1 This is a front view schematic diagram of this utility model.
[0012] Figure 2 This is a top view of the present invention.
[0013] The labels in the attached diagram are: 1-RFID chip layer, 2-first encapsulation layer, 3-second encapsulation layer, 4-fabric layer, 5-seam area, 6-printing layer, 7-bottom film, 8-coating. Detailed Implementation
[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.
[0015] Example: An RFID tag tape, such as Figure 1 As shown, it includes an RFID chip layer 1, which includes an RFID chip and an antenna connected to the RFID chip. The RFID chip layer 1 is an existing structure.
[0016] The outer side of the RFID chip layer 1 is provided with a first encapsulation layer 2 and a sealing second encapsulation layer 3 in sequence. The thickness of the second encapsulation layer 3 is less than 0.2 mm. At least one end of the second encapsulation layer 3 forms a sewn area 5. A fabric layer 4 is provided between the first encapsulation layer 2 and the second encapsulation layer 3. A portion of the fabric layer 4 is located within the sewn area 5. The fabric layer 4 is woven from polyester yarn or nylon yarn. A printing layer 6 is provided on the outer side of the fabric layer 4.
[0017] The first encapsulation layer 2 includes a base film 7 located below the RFID chip layer 1 and a cover film 8 located above the RFID chip layer 1. The antenna is fixed to the base film 7. Both the base film 7 and the cover film 8 are made of PET. The thickness of the base film 7 is 25-30 μm, and the thickness of the cover film 8 is 8-10 μm.
[0018] The second encapsulation layer 3 is made of liquid silicone, and the RFID chip layer 1 and the first encapsulation layer 2 are sealed and encapsulated within the second encapsulation layer 3.
[0019] exist Figure 1 To more clearly show the structure of each layer, the thickness ratio has been adjusted. The actual RFID trademark strip is flat with a uniform thickness of no more than 0.5mm.
[0020] The preparation method includes the following steps in sequence:
[0021] 1) Conductive ink is applied to the base film 7 using a printing process to form an antenna. Then, the RFID chip is attached to the antenna using conductive adhesive, forming an RFID chip layer 1 on the base film 7. The RFID chip requires low thickness and can be the same type of RFID chip used in RFID paper electronic tags.
[0022] 2) Add a coating 8 to the RFID chip layer 1. Part of the coating 8 is fixed to the RFID chip layer 1, and the other part of the coating 8 is fixed to the base film 7 in the cutout part of the antenna. The fixing method can use conventional coating processes, such as dry coating process or heat coating process.
[0023] 3) Fix the fabric layer 4 on the base film 7. The conventional adhesive process can be used for fixing. The fabric layer 4 has a printing layer 6 pre-printed with relevant information.
[0024] 4) Apply a primer, such as KH-560 or KH-570, to the film 8 and wait for it to dry. The primer is to increase the adhesion between the silicone and the film 8 and prevent the silicone from peeling off.
[0025] 5) Immerse it in transparent liquid silicone, take it out, and dry it at a temperature below 100°C to prevent PET deformation (deformation temperature between 120°C and 150°C) to form the second encapsulation layer 3. The information of the printed layer 6 can be seen through the second encapsulation layer 3.
