NOVELTY - Durable antibacterial fiber fabric based on cotton fiber comprises cotton fiber, ammonium ceric nitrate, anion modifier, terminal amino hyper-branched polymer, graphene oxide, cotton fiber, ammonium ceric nitrate, anion modifier, terminal amino hyper-branched polymer, mass ratio of the graphene oxide is 10-20 :4-60 :1-4: 2-4: 2-4: 2-4. USE - Durable antibacterial fiber fabric based on cotton fiber. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the method for preparing lasting antibacterial fiber fabric based on cotton fire, which involves: i.soaking the cotton fiber after alkalization treatment to ammonium ceric nitrate solution ultrasonically processing for 1-2 hours, under the protection of nitrogen adding anion modifier to continuously ultrasonic for 1- 2 hours; ii.taking out and washing drying to obtain the pre- treated cotton fiber; iii.adding the terminal amino hyperbranched polymer into the ethanol water solution stirring uniformly under the protection of nitrogen adding pre-treated cotton fiber stirring 50-70degrees Celsius, 1-2 hours washing vacuum drying to obtain the grafted cotton fiber; iv. and,adding the graphene oxide into diluted acid stirring uniformly adding grafted cotton fiber stirring 70-90degrees Celsius, 1-2 hours, taking out and washing drying spinning weaving to obtain the durable antibacterial fiber fabric based on cotton fiber.
