A production method of a technical fabric from 100% recycled PET modified with carbon nanotubes, wherein the method contains steps in which: - a warp of yarn obtained from 100% recycled PET filaments is warped with a thickness ranging from 40 to 334 dtex, preferably 84 to 334 dtex and more preferably 84 to 167 dtex; - the warp is tied on the loom, preferably using an automatic warp-tying machine; - a weft of yarn obtained from 100% recycled PET filaments, with a thickness ranging from 58 to 668 dtex, preferably 78 to 501 dtex, and preferably 167 to 334 dtex is threaded on a loom; - after loom activation, a fabric pattern is established and weaving is carried out; - an aqueous suspension of carbon nanotubes is prepared, which contains carbon nanotubes in an amount from 0.05 to 2% by weight, based on the fabric weight, preferably 0.1% to 1% by weight, and most preferably 0.125% to 0.5% by weight, and surfactants, preferably anionic surfactants in an amount from 0.1 to 5% by weight, based on the fabric weight, preferably 0.25% to 3% by weight, and most preferably 0.5% to 1.5% by weight, preferably in a homogenizer; - a process of carbon nanotube application is carried out with the use of retention devices in hermetic conditions, under appropriate pressure from 1 to 5 bar, preferably 2 to 4 bar, most preferably 2 to 3 bar, at 30 to 70°C, preferably 40 up to 60°C, most preferably 45 to 55°C, wherein during this process the fabric in the nanotube suspension is rewound at a speed of 150 to 500 m/min, preferably 250 to 350 m/min, most preferably about 300 m/min; - the fabric is dried at 160°C to 220°C, with a fabric web feed rate of 10 m/min to 30 m/min; - the fabric is rinsed at least once with water and a part of the suspension is recovered for its reuse; - the rinsed fabric is subjected to a thermal stabilization in order to maintain its physicochemical parameters, and drying; - the dried fabric is rolled on rollers, labeled and subjected to a final quality control; then the fabric is cut into smaller batches; wherein the fabric stabilization is carried out by annealing the fabric strip at 180°C to 220°C, with a fabric web feed rate of 15 to 30 m/min. - a warp of yarn obtained from 100% recycled PET filaments is warped with a thickness ranging from 40 to 334 dtex, preferably 84 to 334 dtex and more preferably 84 to 167 dtex; - the warp is tied on the loom, preferably using an automatic warp-tying machine; - a weft of yarn obtained from 100% recycled PET filaments, with a thickness ranging from 58 to 668 dtex, preferably 78 to 501 dtex, and preferably 167 to 334 dtex is threaded on a loom; - after loom activation, a fabric pattern is established and weaving is carried out; - an aqueous suspension of carbon nanotubes is prepared, which contains carbon nanotubes in an amount from 0.05 to 2% by weight, based on the fabric weight, preferably 0.1% to 1% by weight, and most preferably 0.125% to 0.5% by weight, and surfactants, preferably anionic surfactants in an amount from 0.1 to 5% by weight, based on the fabric weight, preferably 0.25% to 3% by weight, and most preferably 0.5% to 1.5% by weight, preferably in a homogenizer; - a process of carbon nanotube application is carried out with the use of retention devices in hermetic conditions, under appropriate pressure from 1 to 5 bar, preferably 2 to 4 bar, most preferably 2 to 3 bar, at 30 to 70°C, preferably 40 up to 60°C, most preferably 45 to 55°C, wherein during this process the fabric in the nanotube suspension is rewound at a speed of 150 to 500 m/min, preferably 250 to 350 m/min, most preferably about 300 m/min; - the fabric is dried at 160°C to 220°C, with a fabric web feed rate of 10 m/min to 30 m/min; - the fabric is rinsed at least once with water and a part of the suspension is recovered for its reuse; - the rinsed fabric is subjected to a thermal stabilization in order to maintain its physicochemical parameters, and drying; - the dried fabric is rolled on rollers, labeled and subjected to a final quality control; then the fabric is cut into smaller batches;
