Description
Technical field
The invention belongs to textile technology field, it is related to ionic liquid in the compound fibre of polyethylene terephthalate (PET)
Application in dimension, can prepare the PET composite cellulosic membranes of antibacterial by ionic liquid using spining technology.
Background technology
In life, people inevitably touch the microorganisms such as various bacteriums, fungi.These microorganisms are in suitable ring
Breeding can be mushroomed out under the conditions of border, and is spread disease by contact, influence people's is healthy.In daily life, respectively
The ground that textile is the good existence of these microorganisms is planted, is also the important propagating source of disease, bag of the human lives in microorganism
Among enclosing.Fiber can absorb many microorganisms, if environment is suitable, they will breed rapidly, and a variety of danger are produced to human body
Evil.In recent years, the antibiotic property of fibre is increasingly paid close attention to by people.Fiber and textile with antibacterial action grind
Studying carefully has extremely important meaning.
PET, is that terephthalic acid (TPA) and ethylene glycol occur esterification gained.PET is milky or light yellow, highly crystalline
Polymer, surface smooths glossy.PET has good mechanical property, and impact strength is 3-5 times of other films, resistance to
Folding endurance is good.It is oil resistant, resistance to fatty, resistance to diluted acid, alkaline-resisting.With excellent high temperature resistant, resistance to low temperature, can be in 120 DEG C of temperature ranges
Interior long-term use, is resistant to 150 DEG C of high temperature in a short time, and resistance to -70 DEG C of low temperature, due to its good characteristic, is made in many fields

The beneficial effects of the invention are as follows：
PET nano-composite fibers film shows extremely excellent antibiotic property in the present invention, respectively to gram-positive bacteria gold
Staphylococcus aureus and Gram-negative bacteria Escherichia coli show very excellent antibacterial and sterilized characteristic.
The reason for present invention selection ionic liquid, is as follows：(1) ionic liquid is made up of zwitterion completely, and its fusing point is usual
Less than 100 DEG C and with polarity very high, this cause ionic liquid and polymer the compound operability having easily and can
Processability.(2) ion liquid anti-virus activities and the mechanism of sterilization are as follows：The phospholipid layer of bacterial cell wall surface causes that bacterium surface is usual
It is negatively charged, positive charge or conjugation positive charge are shown on ionic liquid cation, the two attracts each other because of electrostatic interaction so that thin
Bacterium cell membrane finally dissolving and ruptures, cytoplasm (i.e. nutriment) inside and outside cell membrane cannot normal delivery, final bacterium is dead
Die, so as to reach sterilized and antibacterial effect.In addition ionic liquid is organic and non-volatile small molecule, with ion very high
Mobility, easily infiltrates into and oozes out, and after sterilized and antibacterial, its concentration does not occur any change, can forever sterilized and suppression
Bacterium.(3) compared with commercially available organic antibacterial agent, the ionic liquid of high content will not also occur PET precipitation phenomenons, i.e., without common
" bloom " phenomenon of organic antibacterial agent, its stable existence in PET matrix.(4) with most widely used silver system antibacterial fibre
Dimension is compared, and it is not in " reunion " phenomenon of ionic liquid body phase in the case of high content, also, and ionic liquid disperses in PET
Uniformly.
In the present invention, ionic liquid and PET have synergy, the PET of final supported ion liquid on anti-microbial property
Its antibacterial of anti-bacterial fibre and bactericidal properties are superior to single PET and single ionic liquid.
The present invention using electrostatic spinning technique prepare gained film in fiber draw ratio it is larger, specific surface area is high, its with
The interaction of ionic liquid is higher, and final constraint ionic liquid is in PET so that ionic liquid reaches permanent antibacterial effect；
Other technologies often cause " bloom " phenomenon of ionic liquid so that ionic liquid is separated out in pet sheet face, final to disappear.
Antibacterial PET composite fiber thin film of the invention can be applied in fields such as medical science, biology, environmental protection, weavings.

Close power supply.
PET composite fiber thin films prepared by comparative example 1, embodiment 1~10 are carried out into antibiotic property test, selected by it
Strain is gram-positive bacteria (G+) staphylococcus aureus and Gram-negative bacteria (G-) Escherichia coli.
The antibiotic property effect of the PET composite fiber thin films prepared by the comparative example 1 of table 1, embodiment 1~10 is (for large intestine bar
Bacterium and staphylococcus aureus)
As shown in table 1, pure PET (comparative example 1) is poor to the anti-microbial property of two class common bacterias.For example, pure PET is fine
Tie up and there was only 10% to the antimicrobial efficiency of staphylococcus aureus, and to the antimicrobial efficiency of Escherichia coli compared with the former a height of 16%.
Difference on two class bacterium antibacterial effects is due to caused by the different bacterial structure of two class bacteriums.Staphylococcus aureus
Cell membrane is thicker and peptide glycan only has 1-2 layers in the cell membrane of Escherichia coli, and its cell membrane is relatively thin.So, pure PET is to big
The antibiotic property of enterobacteria and staphylococcus aureus is all poor, and such case can more show PET pairs in a humid environment
The growth of bacterium.Embodiment 1 is the PET nano-composite fibers of the antibacterial prepared by commercially available organic antibacterial agent, and it is thin to two classes
The antimicrobial efficiency of bacterium is respectively 20% and 25%, is improved compared with comparative example 1.But, as organic antibacterial agent, its volatilization
Property is more serious, and has a certain degree of precipitation in fiber surface, shows as " bloom " phenomenon.Embodiment 2 is fine silver system PET antibacterials
Dimension, its antimicrobial efficiency to two class bacteriums is respectively 24% and 30%, is also improved to some extent compared with comparative example.But, silver
Nano-particle is inorganic antiseptic, and it is easily reunited, and this causes that material shows inhomogeneities.The anti-bacterial fibre commercially available with two classes
Compare, ionic liquid not only shows excellent antibiotic property, the ionic liquid of high content does not show " bloom " phenomenon yet, while
" reunion " phenomenon of ionic liquid phase region is not shown yet.For example, the PET under 5% ionic liquid (i.e. embodiment 5) doping is fine
Tie up and 76% and 78% is respectively to the antibiotic property of two class bacteriums, compared with comparative example 1, have significant improvement.With ion
The raising of content liquid, the antibiotic property of PET nano-composite fibers gradually rises, and final up to more than 99.
In sum, the PET composite fibres composite membrane of the invention bacterium common to two classes show it is excellent antibacterial and
Bactericidal effect, shows that ionic liquid is the excellent antiseptic of PET composite fibres, and its Antibacterial Mechanism is as follows：Bacterial cell wall surface
Phospholipid layer cause that bacterium surface is generally negatively charged, shown on the cation of ionic liquid positive charge or conjugation positive charge, two
Person attracts each other because of electrostatic interaction so that bacteria cell wall finally dissolves and ruptures, cytoplasm inside and outside cell membrane (i.e. nutrients
Matter) cannot normal delivery, final bacterial death, so as to reach sterilized and antibacterial effect.Simultaneously as ionic liquid and PET
Preferable compatibility, even if " bloom " and " reunion " phenomenon of ionic liquid does not occur under addition high yet in ionic liquid.This
Carried with very big with research at present and the lower anti-bacterial fibre of the wider organic antibacterial agent doping of application and silver system anti-bacterial fibre
It is high.
