Zinc nitrate hexahydrate and the cabaltous nitrate hexahydrate of 2mmol be dissolved in the mixed solvent, obtained after magnetic agitation 5h transparent molten
Then the clear solution is transferred in ptfe autoclave by liquid, after reaction kettle is sealed again 170 DEG C in constant temperature oven
Keep 20h, natural cooling, the precipitation deionized water and ethyl alcohol eccentric cleaning 5 times that reaction is generated, then 90 DEG C of drying boxes again
Middle drying 12h, dry sample is placed in 820 DEG C of Muffle furnace and calcines 100min, obtains ZnO/ZnCo2O4Hollow ball；
Step 2 prepares nanometer Ag-Zn-CuO thorniness particles
It takes 10ml distilled water to pour into beaker, the copper acetate of 0.15g is dissolved in distilled water, is stirred continuously, acetic acid is added
Then the ethyl alcohol of 90ml is added in zinc, continue to stir 2h, then ultrasound 15min, supersonic frequency 1500W；Add mass concentration
PH value for 28% ammonium hydroxide adjusting reaction system is 7.9, then proceedes to ultrasonic 1h, supersonic frequency 800W, after reaction, high speed
It is collected by centrifugation precipitation, high speed rotating speed is 15000r/min, precipitation distilled water and ethyl alcohol is respectively washed 3 times, then again
80 DEG C of vacuum drying 3h, obtain Zn-CuO particles；
Then, dioctyl sodium sulfosuccinate is dissolved in isooctane oil phase, with substance withdrawl syndrome be 0.1mol/L two
Butyric acid dioctyl ester sodium sulfonate solution, is separated two parts of A, B, and every part of volume is 5ml；
The above-mentioned Zn-CuO particles of 10g are weighed, by itself and AgNO3It is scattered in aqueous solution, magnetic agitation 5h under room temperature obtains Zn-
CuO particles and AgNO3Aqueous solution C；
The aqueous solution C of 1ml is added in A, microemulsion E is obtained；1ml ascorbic acid solutions are added in B, obtain microemulsion F；
Microemulsion E, microemulsion F are stirred into 30min respectively, then microemulsion F is slowly dropped in microemulsion E, after being added dropwise, after
Continuous stirring 1h finally washs mixed solution with ethyl alcohol to the reaction was complete, is then centrifuged for separation, vacuum drying obtains nanometer Ag-
Zn-CuO thorniness particles；
Step 3 prepares antiseptic
According to mass ratio, by nanometer Ag-Zn-CuO thorniness particle, ZnO/ZnCo2O4Hollow ball and titanate coupling agent are added to
It in deionized water, stirs, obtains antibacterial slurry, be then baked to, calcine 3h in 500 DEG C under nitrogen protection,
It pulverizes to get antiseptic；
Step 4 prepares anion emission agent
According to mass ratio, by tourmaline anion powder, diatomite, titania nanoparticles, ZnO/ZnCo2O4Hollow ball and
Titanate coupling agent is add to deionized water, and is stirred, and is obtained anion slurry, is then baked to, in nitrogen
4h is calcined in 420 DEG C under protection, is pulverized to get anion emission agent；
Step 5 prepares polyester fiber.
