NOVELTY - Preparing graphene underwear fabric comprises (S1) using graphene nanomaterials, chemical fibers, and artificial fibers to make textile yarns through spinning, (S2) weaving equipment and structure, (S3) knitting with triangular or row needles, (S4) using high-temperature dyeing vat bath ratio 1:10-15 and temperature 110-125°C, keep warming for 30-40 minutes, and cooling by 1°C/minute, using a tension-free dryer with a drying temperature of 150-160°C and a drying speed of 10-15 yards/minute, using a 50-roller drawing machine for drawing, where the card clothing density is 360-420 needles, the wool height after shearing is 0.5-2 mm, the setting adopts a high-temperature stenter setting machine, adding soft and smooth additives, the temperature is 180-195°C, and the speed is 15-20 yards/minute, and (S5) remaking into graphene underwear fabrics according to the required door width and square meters, where the stretch ratio of the fabric is 1:2-3. USE - The method is useful for preparing graphene underwear fabric, which is useful for warming, inhibiting bacteria and far infrared heating, and promoting human body microcirculation. ADVANTAGE - The underwear fabric can quickly receive far-infrared heat when worn in winter, enhances skin comfort, can lock the temperature well, and solves the problems of warmth, ventilation, comfort and antibacterial function. DETAILED DESCRIPTION - Preparing graphene underwear fabric comprises (S1) using graphene nanomaterials, chemical fibers, and artificial fibers to make textile yarns through spinning and spinning processes in specified proportions (graphene content 0.1-10%), where the thickness of textile yarn is 32-80 counts for cotton yarn, and 20-200D for chemical fiber, (S2) weaving equipment and structure, where the double-sided circular knitting machine adopts three-layer weaving method, the first layer is graphene honeycomb layer, the second layer is a hollow insulation layer, and the third layer is an encrypted temperature lock layer, (S3) knitting with triangular or row needles, (S4) using high-temperature dyeing vat bath ratio 1:10-15 and temperature 110-125°C, keep warming for 30-40 minutes, and cooling by 1°C/minute, using a tension-free dryer with a drying temperature of 150-160°C and a drying speed of 10-15 yards/minute, using a 50-roller drawing machine for drawing, where the card clothing density is 360-420 needles, the wool height after shearing is 0.5-2 mm, the setting adopts a high-temperature stenter setting machine, adding soft and smooth additives, where the temperature is 180-195°C, and the speed is 15-20 yards/minute, and (S5) remaking into graphene underwear fabrics according to the required door width and square meters, where the stretch ratio of the fabric is 1:2-3.
