Rate is 20KHz, obtains clear gel, is then washed with distilled water to AgNO3Solution inspection does not measure Cl?, then washed with ethyl alcohol
It washs 3 times, the zirconium oxide presoma after washing is put into thermostatic drying chamber, in 60 DEG C of dry 15h；
Step 2 prepares filler A
Zirconium oxide presoma, ZnO nanoparticle and titanate coupling agent are add to deionized water, stirred, is obtained
It to far infrared additive slurry, is then baked to, under nitrogen protection in 360 DEG C of calcining 5h, pulverizes to get filler A.
7. polyester fiber according to claim 3, which is characterized in that in filler B, the tourmaline nano particle diameter is
100nm。
8. polyester fiber according to claim 7, which is characterized in that in filler B, the mass fraction of each substance are as follows: electrical
17 parts of stone nano particle, 11 parts of ZnO nanoparticle.
9. polyester fiber according to claim 3, which is characterized in that in filler C, the NiFe2O4The partial size of nanoparticle
For 30~50nm；In filler C, the mass fraction of each substance are as follows: NiFe2O45 parts of nanoparticle, 2 parts of ZnO nanoparticle.
10. polyester fiber according to claim 9, which is characterized in that the preparation process of the filler C are as follows:
Step 1, NiFe is prepared2O4Nanoparticle
It weighs 10g polyethylene glycol and 7g dodecyl benzene sulfonic acid ammonium is dissolved in 20ml distilled water, the Fe of 2mol is then added
(NO3)3·9H2O, the Ni (NO of 1mol3)2·6H2O, adjusting pH value with urea is 11.5, stirs evenly, mixed liquor is transferred to height
It presses in kettle, 20h is reacted at 270 DEG C, then natural cooling, after separation of solid and liquid, washing, drying, solid matter is existed
400min is warming up at 870 DEG C and calcines 10h, obtains NiFe2O4Nanoparticle；
Step 2 prepares filler C
By NiFe2O4Nanoparticle, ZnO nanoparticle and titanate coupling agent are add to deionized water, and are stirred,
Electromagnetic shielding additive slurry is obtained, is then baked to, under nitrogen protection in 450 DEG C of calcining 5h, pulverizes to get filling out
Expect C.
