Description
Technical field
The present invention relates to a kind of microgravity suspension centrifugal spinning method, belong to textile technology field.
Background technology
Centrifugal spin its principle and be: spinning solution or melt are thrown away by the centrifugal force utilizing high speed rotating spinning device to produce
Nozzle also produces initial jets, subsequently drawn and be solidified to form superfine fibre.
In centrifugal spinning, the forming process of fiber can be generally divided into the three below stage: the generation in initial jets source, penetrates
The drawing-off of stream and solidification and three processes of collection of fiber.Wherein the first stage determines that can spinning be normally carried out,
It it is the primary premise of centrifugal spinning；Second stage determines pattern and the performance of fiber, is to close the most in centrifugal spinning
One stage of key；Phase III is mainly responsible for the collection of fiber, is to determine that can centrifugal spinning carry out industrialization
One key factor of application.The above three stage influences each other, the final pattern determining fiber and serviceability.

Machine.1998, Akzo Novel N.V. Corp of Holland disclosed a kind of solwution method centrifugal spinning equipment in China
Patent CN1177385A, this equipment feature is that coagulator flows in the surface circulation of fiber collector, but should
Method defect is that the requirement of spinning liquid is high, product variety is single and fiber strength is low.Enter 21 century, with
The research of Pan American branch school, the University of Texas Karen Lozano team of the U.S. is the most deep, and they were Shen in 2009
Patent US20090280325A1 please discloses different types of device for spinning, including with four-way drain
The spinning disc of groove, the syringe of different spray nozzles shape and with metallic grid as the spinneret orifice etc. of filator, profit
This device, KarenLonazo team is used successfully to achieve such as: PAN, PEO, PS and ABS etc.
Conventional material carries out the fiber trying to spin and obtained diameter at 1 microns.At present in the U.S., except the U.S.
Centrifugal spinning is theoretically studied the deepest by the team that the Karen Lozano in Pan American branch school, University of Texas leads
Outside entering, the Fiberio company cooperated with Karen Lozano, registers Forcespinning trade mark, has begun to
Building world head and overlap centrifugal spinning production line, its production efficiency exceedes other nanofiber the most out and away and prepares
Technology, the centrifugal spinning equipment that the said firm produces is currently also to represent the centrifugal top level spinning industrialization, its
PA6 nanofiber prepared by middle Fiberio, diameter Distribution is 110 ran, the most right
Such as: polyacrylonitrile (PAN), polycaprolactone (PCL), polyvinylidene fluoride (PVDF), polyvinyl pyrrole
Alkanone (PVP), polybutylene terephthalate (PBT), polypropylene (PP), polylactic acid (PLA), mix
Stannum Indium sesquioxide. (ITO), titanium dioxide (TiO2), silicon dioxide (SiO2), zinc oxide (ZnO), dioxy
Change zirconium (ZrO2), Barium metatitanate. (BaTiO2), aluminium oxide (Al2O3) etc. carried out centrifugal spinning, but root
According to Forcespinning technology from existing documents and materials, its fiber prepared is short fibre.
Filamentation process is spun, in order to alleviate the rough air impact on jet drawing process, V.R.Gori according to centrifugal
Dev and S.Ramakrishna etc., have developed a kind of enclosed centrifugal spinning device.The feature of this device is
Catcher is arranged on immediately below cylindrical spinning device, and nozzle side is provided with a flow generator, and whole device is adopted
With the distribution form of " up-down structure ", being thrown away by nozzle by given spinning solution, the fiber produced subsequently exists
The underface of spinning device winds and cambium layer aggregated(particle) structure step by step, then, will stack gradually and realize fibrous membrane winding receipts
Collection.Utilize flow generator that " tangentially " air-flow forced near nozzle is become " radially " air-flow.In reality, because of in
The air pressure in heart region, less than the air pressure in outside, at nozzle faint down draft formed below, further improves
The collection efficiency of fiber；The fiber of looping on nozzle can effectively be beaten by the most this " radially down draft "
Dissipate so that floating fiber is difficult to be winding on spinning device, and this method is not likely to produce compared with additive method
(fiber of random distribution is rotated spinning device winding and is wrapped with a large amount of fiber, Yi Zao at its sidewall obstructing problem
Become spray nozzle clogging phenomenon).The collection system additionally closed makes device be isolated with external environment condition, is prevented effectively from
The interference of external air flow, is conducive to the generation of internal humiture.Distribution of fiber diameters prepared by the method is relatively
The degree of orientation for concentration, fiber is the highest and is not likely to produce spray nozzle clogging phenomenon, to some noxious substance
Spinning, improves safety.But the deficiency of this device is that yield is relatively low, still edge on collection mode
The thinking of annular collection, although the impact of air-flow is effectively reduced by the fibrous membrane of preparation, but at mass
Still there is bigger difficulty in preparation aspect.The most meanwhile, S.Mahalingam and Mohan
Edirisinghe proposes the preparation method of centrifugal flow superfine fibre, and the method depends on the height within spinning device
Pressure nitrogen and the spinning device of high speed rotating.Its spinning process is more closely similar to traditional melt-blown, except for the difference that the former profit
Producing jet with centrifugal force, the latter utilizes screw extruder and dosing pump to produce elongate fluid.Compare tradition from
Heart spinning process, the drawing effect of jet is reinforced by air drag, and the level of stretch of jet experience is far above passing
System centrifugal spinning method.Owing to the cylindrical spinning device of this device is fitted without " flow generator ", thus actual
During spinning, create the phenomenon that fiber roll is wound on spinning device, but because there is high pressure nitrogen air-flow at nozzle,
Nozzle is not covered by the fibrous membrane making looping, hence without producing obstructing problem.It is high that the method has yield,
Fibre diameter is thin and is prone to the advantages such as mass production.It is limited in that device based on the method is the most complicated,
Sealing between high pressure nitrogen and the spinning device of high speed rotating needs to design complicated seal structural part；The most powerful
Air-flow fiber is dispelled, be unfavorable for disposable film forming, therefore its product also need to certain post processing could be real
The preparation of existing nano fibrous membrane.
Basically, two key issues that puzzlement centrifugal spinning technology develops further at present, respectively: fiber
Collect continuously and effective generation of fiber morphology.In reality, above-mentioned two problems is again highly dependent, receives
Movement locus and the loading process of jet are had a major impact by mode set, the centrifugal spinning that particularly looks to the future big
Sizable application, causes traditional annular collection method and does not meets the demand of following centrifugal spinning technology development.
About the problem of this respect, have been obtained for the attention of numerous research worker.In this context, receive based on electrostatic
The centrifugal spinning technology of collection becomes a study hotspot of people recently, and concrete principle is as follows: pass through electrostatic force
Intervening the loading process of jet, the direction of motion not only changing jet also optimizes the stretching of jet simultaneously
Process.It is that centrifugal spinning technology brings the advantage that by this principle: solve the company of fiber in centrifugal spinning
Continuous collection problem, improve the peripheral stream condition of spinning device and improve pattern and the performance of fiber simultaneously.But
Owing to electrostatic exists, centrifugal spinning technology based on electrostatic collection is caused to there is the shortcomings such as power consumption is high, safety is low.
In sum, based on annular collect centrifugal spin first by fibre spinning annular spread in centrifugal spinning tank week
On the reception pillar enclosed, then it is collected through air-flow, is a kind of centrifugal spinning method of two-step method, and obtain
Fiber is discontinuous short fibre, and efficiency is low；The fiber that centrifugal spinning method based on electrostatic collection obtains is the most not
Continuously, and whole process is with high-pressure electrostatic, causes power consumption height, and safety coefficient is low, and efficiency is low.
