Embodiment Construction

[0026]2. In the present invention, the fabric is cotton fabric, specifically one of pure cotton and polyester-cotton, and the purity of the cotton content reaches at least 80%, so as to improve the wearable comfort of the fabric, and also improve the bending characteristics of the fabric, so that based on The fabric wearing the radio frequency tag is better bonded to the user's skin to improve the affinity and air permeability of the fabric. The drying environment needs to be in a clean room environment and the ambient temperature range is between 22-26°C, avoiding environmental pollution. The dust and impurities in the fabric soak into the surface of the fabric, which affects the overall cleanliness of the fabric, and also affects the electrical conductivity of the surface circuit of the fabric in the later stage. It is divided into three steps when the coated fabric is treated in an oven at 120°C for 20 minutes, which can fully clean the fabric. Drying treatment, so that the ...

Abstract

The invention provides a fabric wearable radio frequency tag manufacturing method based on an ink-jet printing technology, which comprises the following operation steps: step 1, fabric base layer treatment: firstly, a user puts a fabric into absolute ethyl alcohol for ultrasonic treatment for 20 minutes, then suspends and dries the fabric in the air, then dissolves 5g of P4VP into 100ml of absolute ethyl alcohol (solution I), then dissolves 1.2 g of SU-8 in 100 ml of 1, 4-dioxane (solution II), fully mixes the solution I and the solution II according to a ratio of 1: 1, immerses the fabric into the mixed solution, and airs the fabric in the air after the immersion is completed. According to the invention, through cooperation of materials and step flows, an ink-jet printing frontier technology is adopted, and ink-jet printing can be carried out by the ink of the organic polymer and the metal oxide, so that the transistors can be manufactured on various plastic substrates in a large scale; therefore, the problems that a traditional fabric wearable radio frequency tag manufacturing method is low in wearing comfort, poor in flexibility and high in cost are directly solved.

Description

technical field [0001] The invention relates to the field of electronic textiles, in particular to a fabric wearable radio frequency tag manufacturing method based on inkjet printing technology. Background technique [0002] Radio frequency means the electromagnetic frequency that can radiate into space. The frequency range is from 300kHz to 300GHz. Radio frequency is radio frequency current, referred to as RF. Manufactured by knitting, weaving, embroidery, coating / lamination, printing, dip coating, and atomic layer deposition, commercial conductive thread is used for embroidery, sewing, and weaving, and while traditional conductive thread is very conductive, it is cost and weight Relatively high, and the mechanical flexibility is also limited, so the traditional fabric wearable radio frequency tag manufacturing method has the problems of low wearing comfort, poor flexibility and high cost. [0003] Therefore, it is necessary to provide a fabric wearable radio frequency tag...
