Description
Technical field
The present invention relates to electrostatic spinning technique fields, in particular to a kind of electrostatic spinning reception device and its electrostatic
Spinning process.
Background technology
Electrostatic spinning is a kind of special fiber fabrication process, and polymer solution or melt carry out injection spinning in highfield
Silk.Under electric field action, the drop at syringe needle can be become cone from spherical shape（That is " taylor cone "）, and extend from conical tip
To fiber filaments.This mode can produce the polymer filaments of nanometer grade diameter.
The pattern that roller or tablet receive, roller or tablet one are mainly taken in the collection of electrostatic spinning in laboratory at present
As be metal material, in actual use general cylinder surface or planar surface need covering aluminium foil, copper foil；Or with micropore
Paper, non-woven fabrics etc..Using aluminium foil, when the reception of copper foil, the charge of fiber surface can directly will be electric by conductive metal foil
Lotus guides；When using non-conductive material, it is desirable that material has porous structure, charge can will be fine by the microcellular structure
The charge in dimension table face guides.
It is grounded frequently with syringe needle positive high voltage, reception device in common laboratory, or the method for connecing negative high voltage.Relative to connecing
Ground, negative high voltage can reduce the winged silk phenomenon in spinning process.General negative high voltage directly connects roller or metal belt.
No matter reception device ground connection or the pattern of negative high voltage is connect, with the progress of experiment, since the film of acquisition is most of
All it is the non-conductor of charge, after film reaches certain thickness, fiber surface charge cannot be guided effectively, can film surface be generated
The film defect of some protrusions.It is orientated in the experiment of fiber using high speed collection acquisition simultaneously, general early period can be compared
Orderly fiber, after later stage film thickness increase, charge effectively cannot be guided or be neutralized, and order can be substantially reduced.
In scientific experiment, the non-conducting material film that we are also required to use some fine and close works as use as received vector
When this kind of received vector, since charge cannot guide in time, roller or planar surface can be caused with identical with fiber surface
Charge so that fiber does not fly to collection device.Lead to the failure of an experiment.Simultaneously even with general drum spinning at present, with
The increase of spinning thickness, if the charge of electrostatic spinning film surface cannot be guided effectively, it is possible to can make receiving efficiency
It is lower, or many small protrusions is generated in film surface so that film existing defects.Traditional method for directly connecing negative high voltage because
Negative high voltage is connected on roller, for using nonconducting dense material as received vector, although receiving efficiency can be improved,
But since fiber surface charge cannot be neutralized effectively so that the surface of tunica fibrosa is easier defect occur, and typical defect is just
It is that film surface many protrusions occurs.
Invention content
For the above-mentioned prior art the problem of, a kind of electrostatic spinning reception device of present invention offer and its Static Spinning
Silk method, is efficiently solved and is received using non-porous non-conducting material film；The conventional receiver later stage due to electrostatic charge cannot and
When guide and generate film defect and high speed be orientated collect when, the disordering problem of later stage fiber.
To achieve the above object, the present invention provides the following technical solutions：
A kind of electrostatic spinning reception device, including roller or conveyer belt, the electrostatic spinning reception device further includes ion
Device, the ion generator are located at the side of roller or conveyer belt.
Preferably, the ion generator is anion generator.
Preferably, the ion generator is multiple.
In addition, the present invention also provides a kind of methods carrying out electrostatic spinning using such as above-mentioned device, including：At nozzle
Prior to, concurrently with, or after spinning solution extends to reception device, ion generator is opened.
Beneficial effects of the present invention are as follows：Rear side in spinneret direction introduces ion generator, to neutralize roller or biography
It send and takes accumulative fiber charge, so that the continual reception device of flying to of the spinning liquid energy at nozzle.It uses simultaneously
The method that the surface charge neutralizes, one, so that reception device（Roller or conveyer belt）Material can use non-conductive material,
Such general density of material is lower so that there are many weight saving when making high speed rotary-drum, and it is simple that making high speed rotary-drum also becomes comparison
It is single；Two, make it possible using fine and close non-conducting material film as received vector；Three, after greatly reducing conventional spinning
Phase, film defect problem caused by charge cannot be guided or be neutralized in time so that there is no the limitations of thickness for conventional Static Spinning；
Four, when preparing ordered fiber at a high speed, long-term consistency can be obtained.
