Cloth with shielding NFC reading function and manufacturing method thereof

Abstract

The invention relates to fabric with an NFC reading shielding function in the fields of fabric products and fabric production processes. The fabric comprises a fabric surface layer and a fabric bottom layer, wherein an electrolytic aluminum layer is arranged between the fabric surface layer and the fabric bottom layer, the top surface of the electrolytic aluminum layer is coated with a top layer film, the bottom surface of the electrolytic aluminum layer is coated with a bottom layer film, top layer fabric glue is arranged on the bottom surface of the fabric surface layer, bottom layer fabric glue is arranged on the top surface of the fabric bottom layer, the top layer fabric glue and the t layer film are bonded, and the bottom layer fabric glue and the bottom layer film are bonded. The electrolytic aluminum layer is arranged between the fabric surface layer and the fabric bottom layer, the electrolytic aluminum layer can directly shield the NFC reading function, information of various magnetic cards covered with the fabric cannot be read, and the safety of the magnetic cards is improved. The fabric can be used for producing various bags for accommodating magnetic cards and other valuables, such as handbags, suitcases, card bags, wallets and the like, has the shielding function, prevents the information of the magnetic cards in the bags from being read and guarantees the safety of the magnetic cards.

Description

technical field [0001] The invention relates to the field of cloth products and cloth manufacturing techniques, in particular to cloth with a shielded NFC reading function and a manufacturing method thereof. Background technique [0002] NFC (Near Field Communication, Near Field Communication), also known as short-range wireless communication, is a short-range high-frequency wireless communication technology that allows non-contact point-to-point data transmission and exchange data between electronic devices. This technology evolved from contactless radio frequency identification (RFID), jointly developed by Philips Semiconductors (now NXP Semiconductors), Nokia and Sony, based on RFID and interconnection technology. [0003] Compared with the Bluetooth technology that we currently use more, NFC is more convenient to use, lower in cost, lower in energy consumption, and the speed of establishing a connection is also faster, only 0.1 second. However, the use distance of NFC i...

[0005] On crowded subways or buses, NFC mobile phones can read the bank card information in the trouser pockets of strangers. Although the information read by NFC mobile phones is extremely sensitive to distance, the probability of reading more than 5cm is greatly reduced. However, the existing Criminals may try their best to read the information in the card. If the chip bank card is read by an unauthorized person using an NFC mobile phone, it may cause bank card number, ID number, the last 10 consumption bills, etc. The balance of the mobile phone wallet is read. If the information is confidential, it may lead to theft of bank card funds

[0006] In order to prevent bank card information from being read, there are cloths that can be used to shield NFC reading functions in the prior art. This cloth is used to make various handbags, suitcases, card bags, wallets, etc. for placing magnetic cards. Luggage and other valuables, this structure is to directly coat or electroplate copper, aluminum, nickel and other metal shielding materials on the surface of the base fabric to form a shielding fabric, but it is difficult to coat a metal layer on the surface of the base fabric in the prior art , because the metal layer and the base cloth layer cannot be perfectly bonded, which is a technical bottleneck in the prior art. Therefore, the metal shielding layer can only be sandwiched between the two base cloths by sewing. This process The thickness of the fabric produced is relatively large, and the hand feeling is not good. It is not convenient to make bags that require more detailed craftsmanship, and the fabric production efficiency is low and the aesthetics are poor.
