NOVELTY - Antibacterial auxiliary agent includes 1-3 pts. wt. Chitin, 1-3 pts. wt. hinoki alcohol, 1-3 pts. wt. castor oil, 1-2 pts. wt. wasabi essential oil, 5-18 pts. wt. graphene antibacterial agent, 20-30 pts. wt. peracetic acid antibacterial agent, 20-30 pts. wt. isothiazole antibacterial agent, 4-8 pts. wt. poly-n-butyl methacrylate, 6-8 pts. wt. polystyrene, and 4-5 pts. wt. white mustard powder. USE - Antibacterial auxiliary agent for feather production (claimed). ADVANTAGE - The antibacterial auxiliary agent has a natural antibacterial effect, and the use of graphene antibacterial can cut the insertion of the bacterial cell membrane and directly extract large-scale phospholipid molecules on the cell membrane to destroy the cell membrane and kill the bacteria, and by using poly-n-butyl methacrylate and polystyrene as modifiers, white mustard powder as carrier, a highly dispersed adsorbent was prepared by impregnation method, realizes the adsorption of natural antibacterial agent and graphene antibacterial agent on the down with the help of adsorbent, so that the antibacterial additive can be attached to the down for a long time. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: 1. a method for preparing an antibacterial auxiliary agent, which involves using poly-n-butyl methacrylate and polystyrene as modifiers to impregnate the white mustard powder of the carrier, removing the remaining liquid, and then drying, roasting, activation and other processes to obtain highly dispersed adsorbents, mixing chitin, alcohol, castor oil and wasabi essential oil with each other, pulverizing the material and passing through a 200-mesh sieve to obtain material powder, adding the material powder into the distillation flask of the Clevenger distillation unit, adding distilled water, heating through the temperature control jacket on the device, carrying out water distillation to obtain distillate, and using the oil-water separator to remove water to obtain the active extract, mixing adsorbent, active extract, peracetic acid antibacterial agent, isothiazole antibacterial agent and graphene antibacterial agent in a ratio of 1:1:1.2:1:1 to prepare suspension liquid, and stirring for 0.5-2 hours, filtering and preparing into a slurry to obtain antibacterial additives; and 2. a method for using antibacterial auxiliary agent for feather production, which involves setting the quantitative amount of eiderdown to be 30 kg each time, diluting the prepared antibacterial additive to 30 kg eiderdown*3.5%, 30 kg eiderdown*60% is the amount of water (normal temperature), pumping 30 kg of washed finished down into a special spraying box (the spraying box is equipped with an atomizing nozzle), using the atomizing nozzle to atomize and spraying the mixed antibacterial agent on the down, and spraying while stirring, putting the down into the dryer, and the air pressure of the dryer is controlled at 0.5-0.6 megapascals, and putting the dried down into the cooling box, and finally the packaging is completed.
