NOVELTY - Preparing nano anti-wrinkle fabric involves preparing modified polyurethane fibers, modified polyamide fibers, nano-ceramic fibers, cotton fibers, hemp fibers, and acetate fibers, mixing the fibers and obtaining the nano-wrinkle-resistant fiber by spinning. The nano anti-wrinkle fiber is used as the raw material, soaked the nano anti-wrinkle fiber in the anti-wrinkle finishing agent, soaked for 45 minutes, and prepared the nano anti-wrinkle fabric through the knitting process. The modified polyurethane fiber is prepared by obtaining the polyurethane and N,N-dimethylacetamide solvent and adding to the four-necked flask with a mechanical stirring device, and using the mechanical stirring device to stirring and mixing the mixed solution in the four-necked flask, where the heating temperature is 40-48degrees Celsius. The mixed solution is heated for 1 hours at 54-60degrees Celsius to obtain intermediate (A). The carbon black particles are taken for slicing. USE - Method for preparing nano anti-wrinkle fabric ADVANTAGE - The invention solves the problem that the existing nano anti-wrinkle fabric still has improved space on the mechanical property, and the conductivity and antibacterial performance of the fabric also needs to be improved. The polyamide is modified by biomass graphene which can greatly improve the bacteriostasis rate of Escherichia coli, Candida albicans and Staphylococcus aureus , so as to improve the antimicrobial performance of fabric. DETAILED DESCRIPTION - Preparing nano anti-wrinkle fabric involves preparing modified polyurethane fibers, modified polyamide fibers, nano-ceramic fibers, cotton fibers, hemp fibers, and acetate fibers, mixing the fibers and obtaining the nano-wrinkle-resistant fiber by spinning. The nano anti-wrinkle fiber is used as the raw material, soaked the nano anti-wrinkle fiber in the anti-wrinkle finishing agent, soaked for 45 minutes, and prepared the nano anti-wrinkle fabric through the knitting process. The modified polyurethane fiber is prepared by obtaining the polyurethane and N,N-dimethylacetamide solvent and adding to the four-necked flask with a mechanical stirring device, and using the mechanical stirring device to stirring and mixing the mixed solution in the four-necked flask, where the heating temperature is 40-48degrees Celsius. The mixed solution is heated for 1 hours at 54-60degrees Celsius to obtain intermediate (A). The carbon black particles are taken for slicing, and added the sliced carbon black particles into the high mixer for dispersion treatment. The dispersant is added to the carbon black particles in a spray form, then taken out the carbon black particles in the high-mixer and put them into N,N-dimethylacetamide solvent. A mechanical stirring device, the carbon black particles and the N,N-dimethylacetamide solvent are stirred uniformly to obtain the additive (B). The additive (B) is added into the intermediate (A), and used a mechanical stirring device to heat and stirred the mixture of the intermediate (A) and the additive (B). The heating temperature is 35degrees Celsius, until the additive (B) and the intermediate (A) are completely mixed, and obtained mixture (C). A beaker with a mechanical stirring device is taken, poured water into the beaker, and poured the mixture (C) into the beaker. A mechanical stirring device is used to stir and mixed the mixed solution in the beaker, and obtained uniform blend of carbon black and polyurethane, then granulated the blend of carbon black and polyurethane, and finally put into a vacuum drying oven for drying to obtain a mixture (D) of carbon black and polyurethane. The mixture (D) is put into the desktop plunger melt spinning tester after slicing, and compacted the mixture (D), controlled the extrusion speed to be 1.7 g/minute, and the extrusion temperature to be 180-185degrees Celsius, and obtained the modified polyurethane fiber.
