Problems solved by technology

The traditional washing label antenna cannot meet the washing management function because it is easily damaged
Most of the RFID tags that can meet the washing management function are special RFID tags that are implanted in clothing later. This type of RFID tag implanted in clothing usually affects the comfort of wearing, and both the cost of label production and the later implantation of tags in clothing will increase significantly. work and management costs

Embodiment 1

[0052]The electrical conductivity is 10000000s / m, which is designed to be intermediate a complete loop dipole label antenna 300 in an intermediate, a conductive fiber line having a relative magnetic permeability 100, a diameter of 50 μm, a resistor 30 Ω / m, a tensile strength 40N.Picture 1-1 ,2-13. Down 3, 4-1, 5, 6). The conductive wire and the label chip 100 of the label antenna 300 are attached to the polyester fabric in a polyester fabric. The tape line of the label antenna 300 uses a rope embroidery to attach it to the polyester fabric in accordance with a specific pattern trace, and the needle is adjusted to the polyester fabric, so that it maintains a certain geometric shape, in the ring 301 in the occasional antenna. The label chip 100 is placed, covering the cover layer 400 on the base fabric, and then the label the antenna is folded from the woven antenna unit, and the angle of the ring intersection is not directly in contact with the film chip.

[0056]The electrical conductivity is 10000000s / m, and the relative magnetic permeability 100, the diameter of 50 μm, the resistor 30 Ω / m, the tensile strength 40N conductive fiber line is designed to be intermediate, in the middle of the antenna The label chip 100 is placed in the ring 301. The cotton fabric is a substrate 200, the label antenna 300 and the label chip 11 are attached to the cotton fabric.

[0057]In this example, a multi-conductive metal fiber stranded wire is made of label antenna 300. The cotton fabric is used as the substrate 200, which has extremely high softness, but in the water wash cotton fabric shrinkage, the conductive line contraction, the label working frequency band Variation, outside the 860 to 960 MHz band, the tag performance parameter change is greater than 3dB, and cannot be read normally.

[0059]The electrical conductivity is 10000,000s / m, which is relative to the magnetolence 100, a diameter of 50 μm, and a conductive fiber line 30Ω / m / m, is designed to be intermediate a complete loop dipole tag antenna 300. The tapered mixed textile is a substrate 200, the label antenna 300 and the label chip 100 are attached to the material of the polyester mixed textile. The label antenna uses a rope embroidery to attach it to the polyester blended fabric substrate 200, and the adjustment pin and direction are embedded to the flexible substrate 200, so that it maintains a certain geometric shape, in the middle of the antenna, 301 The label chip 100 is placed, covering the cover layer 400 on the base fabric, and then the label antenna 300 is folded from the woven antenna unit, and the angle of the ring is not directly in direct contact, and is separated by the film chip 100.

Abstract

The invention provides a washable electronic tag integrated with an RFID antenna, and the electronic tag comprises a method for fixing a special conductive wire on the surface of base cloth and a layout form, and is mainly applied to clothing wash labels, clothing trademarks, clothing intelligent laundry tags and the like. A washable tag integrated with a UHF RFID antenna comprises an integrated antenna formed by conductive fiber lines, a label chip and a base material; the conductive fiber lines are fixed to the surface of base cloth in a specific wiring mode, and the base cloth is made of insulating materials. According to the invention, the RFID antenna is fixed on the surface of the base cloth to form the fabric integrated with the RFID antenna, and the fabric can be cut into the RFIDwashable tag, so that the intelligence of the washable tag and the implantation of the source end are realized. The conductive wire adopted by the integrated RFID antenna and the base cloth are combined into a whole in a rope embroidery mode, so that the RFID antenna does not deform and is not structurally changed, and the performance of the RFID tag is more stable when the washing tag and clothesare washed together.

Description

Technical field[0001]The present invention relates to a UHF RFID tag, in particular a UHF RFID tag for washing management, and a method of fabricating.Background technique[0002]RFID technology has been successfully applied to the washing production source label, which is usually used to implant the RFID Inlay to make RFID wash, as apparel sales and logistics management purposes. However, such RFID wash tags cannot be used as a washing management because they cannot meet the clothes multiple water washing. Because the RFID tag is mainly composed of label antenna and tag chip, the role of the label antenna is to transmit and receive electromagnetic signals, and its performance is directly related to whether it is possible to communicate. The traditional washing labeling antenna cannot meet the washing management function due to vulnerability. The RFID tag that meets the washing management function is mostly a special RFID tag that is replaced in the fabric. This type of RFID label is ...
