Description

Technical Field

[0001] The utility model relates to the technical field of RFID tags, in particular to a combined flexible laundry label structure. Background Art

[0002] Traditional RFID tag inlays (pre-laminated products) feature antenna arms etched from PET aluminum. The entire inlay is large and exhibits a certain degree of stiffness. Traditional care labels are double-sided laminates of fabric and PET-based RFID tag inlays. These are relatively thick and exhibit a certain degree of stiffness, making them easily noticeable when sewn onto clothing. Utility Model Content

[0003] This utility model aims to provide a flexible laundry label structure that effectively combines an RFID tag inlay with fabric. The technical solution is as follows:

[0004] A combined flexible care label structure includes an RFID tag inlay and an antenna arm;

[0005] The RFID tag inlay includes a substrate, a loop, and a tag chip; the loop is formed on the substrate, and the tag chip is attached to the opening of the loop to receive excitation from the loop;

[0006] The antenna arm is formed by sewing a conductive aramid thread on a fabric, and the RFID tag inlay is attached to the fabric. The attachment position satisfies the following requirements: the middle of the antenna arm and the loop are arranged in close proximity, so that the loop and the antenna arm form electromagnetic coupling.

[0007] Furthermore, the substrate is a PET substrate.

[0008] Furthermore, the thickness of the RFID tag inlay is no more than 100 μm.

[0009] Furthermore, a "door" shape is formed in the middle of the antenna arm, and the RFID tag inlay is arranged in the area where the "door" shape is located, with three sides facing the antenna arm at a close distance, and the relative distance between the loop and the antenna arm is 0.5mm to 2mm.

[0010] Furthermore, both ends of the antenna arm are straight line structures.

[0011] Furthermore, both ends of the antenna arm are serpentine structures.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] This combined flexible care label structure is coupled with an antenna arm made of conductive aramid thread through the loop of the RFID tag inlay. The antenna arm is formed by sewing the conductive aramid thread directly onto the fabric in a certain shape, fusing the antenna arm and the fabric together to achieve the same stiffness as the fabric. The electronic tag inlay only has a loop and no antenna arm, so it is small in size and thickness. Therefore, it will not significantly increase the local stiffness of the fabric, and the user will not easily feel the presence of the electronic tag on the fabric. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] To further illustrate various embodiments, the present invention is provided with accompanying drawings. These drawings form part of the disclosure of this invention and are primarily used to illustrate the embodiments and, in conjunction with the relevant description in the specification, to explain the operating principles of the embodiments. By referring to these drawings, those skilled in the art will understand other possible implementations and the advantages of this invention. The components in the figures are not drawn to scale, and similar reference numerals are generally used to represent similar components.

[0017] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.

[0018] like Figure 1 and Figure 2 As shown, the present invention provides a modular soft laundry label structure. It includes an antenna arm 4 made of conductive aramid yarn and an RFID tag inlay. The RFID tag inlay comprises a PET substrate 3, a loop 1, and a tag chip 2. The tag chip 2 is adhered to the opening of the loop 1 using a conductive adhesive or other method. The loop 1 is positioned on one side of the middle portion 41 of the antenna arm 4, forming an electromagnetic coupling with the antenna arm 4, thereby deriving energy from the antenna arm 4 to activate the tag chip.

[0019] Compared with traditional care labels, the combined flexible care label structure of the present invention has the following advantages: the antenna arm of this structure is formed by directly sewing conductive aramid thread into a certain shape on the fabric, fusing the antenna arm and the fabric together and matching the stiffness of the fabric; and the electronic tag inlay only has a loop ring without an antenna arm, and is small in size and thickness. Therefore, it will not significantly increase the local stiffness of the fabric, and the user will not easily feel the presence of the electronic tag on the fabric.

[0020] In this embodiment, both ends of the antenna arm 4 are serpentine structures, similar to traditional RFID tags.

[0021] In a specific application, since the antenna arm 4 is directly sewn on the fabric, the length of the combined soft label structure is not limited. The two ends of the antenna arm 4 are preferably in a straight line to minimize signal loss and achieve an optimal impedance ratio with the tag chip 2.

[0022] In this embodiment, the loop 1 and antenna arm 4 are electromagnetically coupled on the same plane. Because the RFID tag inlay consists solely of the loop, it is compact, measuring only one-third or less the size of a conventional RFID tag inlay. Furthermore, the loop utilizes a PET substrate with a thickness of 38 μm, a reduction of at least 75% compared to conventional care labels. Testing of this design's RFID tag inlay has shown that, due to its compact size, even at a thickness of 100 μm, it exhibits no noticeable stiffness, exhibits excellent flexibility, and does not compromise RF transmission performance.

[0023] In this embodiment, the conductive aramid thread can be sewn onto the fabric by a high-speed weaving machine or other equipment that can sew according to a certain regular shape to complete the preparation of the antenna arm.

[0024] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes can be made to the form and details of the present invention without departing from the spirit and scope of the present invention as defined by the appended claims, and all of these changes are within the scope of protection of the present invention.
