Become the sandwich layer in skin-core structure, become polyester layers 3, and the average diameter of polyester core 3 is preferably 14 μm (polyester layers straight
Footpath controls between 14～20 μm), the suitable polyester layers of diameter preferably can be connected with polymer；Polyester in the present embodiment
It is preferably polyethylene terephthalate, in polyethylene terephthalate sandwich layer, is embedded with ZrO2Nanoparticle 6, because
ZrO2Nanoparticle is as far-infrared material, in addition to having heat insulation effect, also has promotion microcirculation in human body, anti-inflammatory analgesic, adds
The health-care effecies such as speed wound healing, activated matrix, the discharge of promotion bodily waste, allaying tiredness, regulation nerve.Meanwhile, in this reality
Execute in example, ZrO2The particle diameter of nanoparticle is 50nm, and content is 2% (ZrO2The content of nanoparticle be preferably controlled in 2.0～
Between 3.5%), if ZrO2Nanoparticle content is too high, can affect the intensity of fiber, too low, can make insulation and health ability
It is deteriorated.
Understanding further in conjunction with Fig. 1, polyvinyl alcohol-ethylene copolymer, in the periphery of polyester layers, encloses formation skin-core structure
Cortex, become polyvinyl alcohol-ethylene copolymer cortex 1, and the thickness of polyvinyl alcohol-ethylene copolymer skin 1 in this embodiment
It is 9 μm (thickness of polyvinyl alcohol-ethylene copolymer cortex can control between 7～15 μm), meanwhile, in order to ensure to inhale
Attached effect, polyvinyl alcohol-ethylene copolymer cortex is loose structure, as many in polyvinyl alcohol-ethylene copolymer cortex in Fig. 1
Shown in pore structure 2, porosity reaches 40～50%, and aperture is 20～50nm, because too low porosity causes foul smell molecule
Absorbability not enough, and too high porosity can affect the mechanical property of polyvinyl alcohol-ethylene copolymer cortex, and after affecting
Phase polymethylacrylic acid diformazan ammonia ethyl ester and Cu2+Form the grafting density of the antibiotic layer of complex, eventually have influence on fiber
Antibacterial ability.Therefore, this enforcement has the polyvinyl alcohol-ethylene copolymer cortex of loose structure, it is possible to body metabolism mistake
The foul smell molecule produced in journey, such as hydrogen sulfide, mercaptan etc., has the absorbability of excellence, hence it is evident that decrease because odor molecules draws
The zest untoward reaction to nervus centralis, oral cavity, throat and stomach risen.

Dimethylaminoethyl acrylate methyl ammonia ethyl ester, and the molecular weight of polymethylacrylic acid diformazan ammonia ethyl ester is that 9.0kDa is (poly-in the present embodiment
The molecular weight control of dimethylaminoethyl acrylate methyl ammonia ethyl ester is between 8.0～10.0kDa), polymethylacrylic acid diformazan ammonia ethyl ester leads to
Cross coordinate bond and Cu2+Complexation forms complex, constitutes the antibiotic layer 4, Cu of polyester fiber2+Firmly it is attached to by coordinate bond
On polyester fiber, play lasting antibacterial ability, and polymethylacrylic acid diformazan ammonia ethyl ester also have the antibacterial ability of excellence,
And Cu2+Play Synergistic antimicrobial performance and enough significantly improve the antibiotic property of polyester fiber；Dimethylaminoethyl acrylate methyl ammonia ethyl ester and Cu2+'s
Mol ratio is preferably 2～3:1, if the content of dimethylaminoethyl acrylate methyl ammonia ethyl ester is relatively low, then can cause dimethylaminoethyl acrylate methyl ammonia
Ethyl ester and Cu2+Adhesion insecure, affect antibacterial durability；If Cu2+Content relatively low, then can affect complex
Antibacterial ability.Polymethylacrylic acid diformazan ammonia ethyl ester in the polyester fiber antibiotic layer of this enforcement preparation and Cu2+Binding ability
Relatively strong, after 30 times are washed, Cu2+Antibacterial ion, almost without loss, has remained in that preferable anti-microbial property, bacteriostasis rate
Remain to be maintained at more than 86%.
Understanding further in conjunction with Fig. 1 and Fig. 2, the end at polymethylacrylic acid diformazan ammonia ethyl ester connects Polyethylene Glycol, and
The molecular weight of the Polyethylene Glycol in this enforcement is preferably 4.0kDa, and the hydrophilic of Polyethylene Glycol can improve the pro-skin of polyester fiber
Property, therefore the surface at polyester fiber forms hydrophilic, skin-friendly layer, shown in the most hydrophilic, husband's layer 5, is being formed
While hydrophilic, skin-friendly layer, moreover it is possible to give the antibacterial electrostatic capacity that polyester fiber is certain, be therefore effectively increased in practicality
The comfortableness of dress, and impart the antistatic effect that polyester fiber is certain.
Therefore the polyester fiber of the present embodiment has several functions concurrently.
