Description
Technical field
This patent is related to electrostatic spinning and silk field is received in rotation, and in particular to a kind of multi-direction rotation applied to electrostatic spinning
Turn wire drawing device and its application apparatus and method.
Background technique
Nanofiber is a kind of superfine fibre of diameter about between 1 ~ 100nm, it has large specific surface area, porosity
It is high, draw ratio is big, surface can and the features such as activity is high, fiber fine degree and homogeneity is high, it is extensive that people have been obtained
Concern, and electrostatic spinning is the technology that can prepare nanoscale or micron order fiber, compared to other methods, this technology is more
It is the convenience that adds, simple, flexibly, and can be adapted for most polymer, principle are as follows: it is applied between spray head and receiver
Add high pressure electrostatic field, and the polymer fluid being polarized is made to overcome surface tension under the action of electric field force, forms high speed electrification
Thin jet stream after thin jet stream refines division under the action of electrostatic field, cools and solidifies, in receiver board by solvent volatilization or melt
Upper formation nanofiber.
Since there is a kind of unstable whips to move state for jet stream thin in spinning process, and divided out in the refinement of thin jet stream
During nanofiber, it is random that refinement, which splits into the direction of silk, so that the orientation of the nanofiber received is different.It is right
It needs fiber to be furnished with the good degree of orientation in some applications of nanofiber, for example does cell culturing bracket using nanofiber
When, relatively good nanofiber body is arranged, cell can be made along regular direction growth.
The parallel rolling of a kind dynamic is provided in the application for a patent for invention disclosure that publication No. is CN104894660A
Cylinder electrode electrospinning device and method, the equipment include PLC controller, syringe pump, spinning head and receiver, described
PLC controller controls syringe pump and receiver, wherein the syringe pump is used for spinning head feed flow, and the receiver is equipped with extremely
Few a pair of parallel roller electrode, the parallel roller bipole receivers and syringe pump cooperate, and dynamic rotary receives fiber.This is specially
Benefit preferably prepares good orientation by parallel pole distributed electric field and turning effort special in parallel roller bipole receivers
The two-dimensional nano fiber of degree, but collect the high fiber of the obtained degree of orientation in this way and be only capable of keeping good in one dimension taking
Tropism, and the nanofiber beam intensity of single dimension orientation is low, is easily damaged, it can not be with conventional textile fabric material (woven fabric, needle
Fabric etc.) there is same extensive use.
Comprehensive previous electrostatic spinning technique, using plate wire drawing device or rotation wire drawing device compared with being collected under the slow-speed of revolution
To nano-fiber material surround and watch that structure is disorderly and unsystematic, without structural in any direction, mechanical strength is weaker.And make
It is available along rotation with rotation wire drawing device at higher rotation speed (rotation wire drawing device linear velocity is higher than electrostatic spinning effluxvelocity)
The nano-fiber material of a dimension ordered arrangement on direction, material is upper with stronger mechanical strength in the direction at this time, and
The mechanical strength being perpendicularly to the direction easily pulls separation not as good as the nano-fiber material of disorderly and unsystematic distribution.Meanwhile
There is trial to receive and distribute dynamic change in the prior art and adjusts rotation receipts silk direction to attempt to obtain the nanofiber of multi-direction ordered arrangement
Structure, but it is cumbersome due to being manually operated, it takes a long time, spinning interval is longer between layers, and connectivity is extremely weak, very easy
Separation.
