Problems solved by technology

This kind of clothing internal label also has the problem of the label described in the aforementioned patent, which affects the wearing comfort
In addition, the reading performance of the label is affected by the difference in the dielectric properties of the marked clothing material. The labels stated in the above patents do not give a specific solution, and how to protect the label of the clothing after mechanical forces such as washing are still good. There are also certain defects in maintaining the original reading effect, which requires a reasonable design of the water-washed UHF RFID tag

Embodiment Construction

[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific implementation examples. It should be understood that these examples are only for illustrating the present invention and are not intended to limit the scope of the present invention. After reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims of the present application.

[0027] Such as figure 1 , 2 As shown in the figure, the planar structure of two UHF RFID tag antennas is shown in the figure. The first is a commonly used UHF RFID antenna; the second is a slight improvement on the basis of the first antenna. The length and width of the two antennas are equal, both are 100×20mm 2 , due to the consideration that the silk screen is printed on the washing label, this small s...

Abstract

The present invention relates to a care label-based UHF RFID tag based on screen printing. A manufacturing method of the care label-based UHF RFID tag based on screen printing comprises the steps of: selecting a care label as a substrate for printing an antenna; then printing electrically conductive printing ink on the substrate to form an antenna through a screen printing method; after drying, bonding a connecting band of a UHF RFID tag chip to the antenna by a conductivity type binder; and finally performing coating protection for the chip, wherein a coating material adopts flexible resin. Compared with the prior art, the care label-based UHF RFID tag of the present invention has the beneficial effects that: the flexibility of the care label is retained by the care label-based UHF RFID tag; the care label-based UHF RFID tag is perfectly fit with clothes; the UHF RFID antenna is endowed with a certain flexibility, and can bear certain bending or deformation; the care label-based UHF RFID tag is simple in structure and convenient in manufacture; the care label-based UHF RFID tag is printed by a screen printing machine, can achieve mass production, and is suitable for popularization.

Description

technical field [0001] The invention relates to a technology for printing a wearable and washable UHF frequency band RFID tag using a flexible water-washable label textile material as a substrate, and belongs to the technical field of combining radio frequency identification with textile and clothing. In the logistics, management and anti-counterfeiting of textile and clothing. Background technique [0002] RFID (Radio Frequency Identification), as a highly intelligent and advanced Internet of Things technology in the 21st century, has penetrated into human daily life and gradually developed. A complete and working RFID system includes at least two parts: electronic tags and reading devices. The electronic tag is an ultra-thin integrated circuit tag composed of coupling elements and chips, and its core components are the chip and the antenna responsible for sending and receiving signals. Compared with traditional information tags, such as barcodes and QR codes, RFID tags h...
