The specific embodiment
The principle of revolving the dish device for spinning as shown in Figure 1.Polymer solution is stored in the container (1), is transported near the center of revolving dish (3) through a measuring pump or delivery pump (2).Under the driving of actuating unit (4), revolve the speed rotation of dish (3) to set, produce centrifugal force.Under action of centrifugal force, polymer solution to around in the process of flight, fission into fiber (5) and by high elongation, solvent evaporates is scattering on the gatherer (6) at last, obtains the nonwoven fabric of superfine fibre.
The core of this device is the garden dish of the stable rotation of a high speed, thereby the axial symmetry that revolves dish itself and associated mechanisms requires very high.Axially off-centre causes machinery and personal safety accident easily.Its power can be variable speed electric motors, particularly, also can be compressed air, as long as enough power can be provided, and velocity of rotation is adjustable, stable getting final product.Under present technical conditions, the design symmetry of rotatable parts, processing, detection and adjustment, and the adjusting of the design of actuating unit, processing and running status and demonstration all are not difficult to realize.These transmission mechanisms that revolve dish also can be located at the top of revolving dish, are convenient to revolve the relative motion between dish and the receiver.
The raw material that revolves the dish spinning is a polymer solution.Say that in principle any soluble polymer can revolve the dish spinning.In order to guarantee that fibre has enough mechanical mechanics properties, require polymer that suitable molecular weight ranges is arranged.Behind selected polymer, select the solvent that is fit to.Require the solvability of solvent strong, nontoxic or low toxicity, volatility is good, and boiling point is at 30-200 ℃, preferred 50-150 ℃.
Every kind of polymer solution generally has spinnable concentration or range of viscosities, excessive concentration, even rotary speed is very fast, solution also disperses not open, and can not become silk, and the fibre diameter that perhaps obtains is very thick, can not satisfy instructions for use.Concentration is low excessively, and solution can not become silk, but is atomized into powder.This should be avoided.The concentration of polymer solution is 1-30% among the present invention, preferred 2-15%, best 5-10%.
Spinning solution through metrological service deliver to revolve the dish surface after, under centrifugal action, at first sprawl into film.It is far away more to leave axis of rotation, and centrifugal force is big more, and flying speed is fast more.Leave when revolving the dish edge, reach maximum speed, become freely falling body then.Test shows that proper as long as the concentration of solution and rotary speed are selected, solution is just fissioned into fiber shape after flying away from and revolving the dish edge.Under centrifugal action, fiber is by high elongation, thereby the fibre diameter that obtains has mechanical strength preferably in micron and sub-micrometer range.The rotary speed of revolving dish among the present invention is in the 1000-20000rpm scope, preferred 3000-15000rpm, best 5000-10000rpm.
In the process that forms, flies and stretch at fiber, the solvent in the fiber volatilizees synchronously, contains certain amount of solvent in the fiber of collecting at last, and making has enough adhesive powers between the fiber, forms nonwoven fabric.Solvent is not too high again, to avoid the fusion of fiber and condenses.So the control of solvent evaporates speed and volatilization degree is another key problem in technology of this method, the solvent boiling point of selecting among the present invention is 30-300 ℃, preferred 50-150 ℃.Next is the flow condition and the temperature of revolving near the environmental gas of dish, and air flow is had friendly relations, and the temperature height is beneficial to solvent evaporates; Secondly be the shape and size of revolving dish again, the diameter of their decision fibers determines the speed and the track of fiber flight, thereby also influences the volatilization of solvent.The diameter that revolves dish among the present invention is generally at 20-200mm, preferred 40-60mm; Its upper surface shape can be a horizontal plane, also can be the garden conical surface and curved surface.The use garden conical surface and curved surface can make solution film fly obliquely upward, are increased in time and length that the space stops, are convenient to solvent evaporates.Can also adopt the nozzle arrangements of circle distribution, guarantee to form fiber shape, improve the homogeneity of fibre diameter.
The rotary speed of revolving dish is very fast, thereby generally makes with light material, for example aluminium alloy.Requirement is revolved enough viscous forces between dish surface and the spinning solution, so that give full play to the acceleration that rotation at a high speed brings.Thereby in case of necessity, can be coated with one layer of polymeric revolving the dish surface, and increase viscous force, do not fallen again by dissolution with solvents.
Because from revolving the fiber that dish flies out, be in the tangential direction of revolving dish substantially, thereby the fiber that drops on the static receiver has tangible directionality, and became uneven (thick middle, thin all around), can not satisfy the requirement of application sometimes.In order to make obtained nonwoven be furnished with isotropism and uniformity preferably, receiver and revolve between the dish should relative motion comprises translation and rotation.Correspondingly, the actuating unit that revolves dish is installed in the top of revolving dish, is convenient to revolve relatively moving between dish and the receiver.
Consider the needs of safety and protection, in design with make when revolving the equipment of dish spinning, also will take corresponding safety prevention measure, as safety sheathing, ventilation, separated from solvent and recovery etc.This is the item in spinning and the chemical industry technical staff general knowledge scope, repeats no more here.
Say that in principle any soluble polymer can revolve the dish spinning.Consider to revolve the advantage and the limitation of dish spinning, it is particularly suitable for the preparation of biodegradable polymers nonwoven fabric.Biodegradable tissue engineering bracket material requires that suitable biodegradation rate is arranged, appropriate pore size, higher porosity, specific area and mechanical strength.Compare with the cavernous body form, superfine fibre nonwoven cloth (felt) has advantages such as degradation speed is fast, and the aperture is big, and porosity height and mechanical strength are good.Prepare nonwoven fabric with rotary disc spinning process, lower than production efficiency height, the cost of cavernous body preparation.Some organizational project as spinal cord and neural reparation and regeneration, requires the hole in the timbering material to have directionality, and cavernous body is then powerless, has only the superfine fibre felt just can serve as.
Can be processed into the biodegradable polymers of tissue engineering bracket, comprise water miscible polymer, as shitosan, transparent phytic acid, sodium alginate, modified cellulose and starch etc.; Oil-soluble polymer, as PLA (PLA), poly-epsilon-caprolactone (PCL), and the random or block copolymer of lactide and glycolide, lactide and 6-caprolactone, 6-caprolactone and glycolide, also have the block copolymer of lactide and ethylene glycol, glycolide and ethylene glycol, 6-caprolactone and ethylene glycol etc.
