[0034] The preparation method of the above-mentioned far-infrared radiation carbon fiber electric-thermal composite fabric is characterized in that, comprising:
[0035] The first step: using the carbon fiber surface coating removal treatment method, the carbon fiber fabric is pretreated to obtain a desized carbon fiber fabric;
[0036] The second step: using the dopamine biomimetic modification method, dissolving dopamine hydrochloride in Tris buffer solution to obtain a dopamine solution, and immersing the desized carbon fiber fabric obtained in the first step in the dopamine solution to obtain a dopamine biomimetic modified carbon fiber fabric;
[0037] The third step: using the fabric post-finishing method, first prepare the far-infrared slurry for enhancing the far-infrared performance, and then use the slurry spraying method to spray the far-infrared slurry on the dopamine biomimetic modified carbon fiber fabric prepared in the second step , to obtain far-infrared radiat...

[0040]A preparation method of far-infrared radiation carbon fiber electric-thermal composite fabric:
[0041] The first step: use the acetone soaking method to prepare 80% acetone solution, first take 80mL acetone and 20mL deionized water, mix them, and soak 5cm×5cm carbon fiber plain cloth in 80% acetone solution, at room temperature (25°C) Dipping for 48h to obtain a desized carbon fiber plain weave fabric;
[0042] Step 2: Dissolve 1.2114g Tris (trishydroxymethylaminomethane) in 1L deionized water, stir for 5min, add 0.1mol / L dilute hydrochloric acid to the solution to adjust the pH until the pH meter shows 8.5 , to obtain a 10mmol / L Tris buffer solution. 2 g of dopamine hydrochloride was dissolved in the prepared Tris buffer solution, and stirred for 5 min to obtain a 2 g / L dopamine solution. The desized carbon fiber plain weave fabric obtained in the first step was immersed in dopamine solution, the bath ratio was 1:50, the reaction time was 4 hours, and the reaction te...
