Abstract
The present invention is a kind of electrostatic spinning device of being made up of electric field case, electrode etc., it is characterized in that being equipped with in electrostatic field the high speed electrostatic spinning device of control free end yarn tail apparatus.
In electrostatic field, installed behind the V-shaped groove that through hole is arranged on the bottom line, can under the acting in conjunction of static and air-flow, play positive control and holding effect, thereby can improve spinning speed free end yarn tail.
Description
The present invention relates to a kind of electrostatic spinning device of forming by electric field case, electrode etc., particularly have the high speed electrostatic spinning device of control free end yarn tail apparatus.
Electrostatic spinning is the straightening of fibers, parallel and form a kind of spinning method that is suspended in the free end yarn tail between two electrodes to the cohesion of electric field center line after utilizing electrostatic force that the high-voltage electrostatic field produces with shredding.At present, the basic principle of the domestic electrostatic spinning device of studying and structure are shown in this accompanying drawing (1) as the structure in the 142nd page in " Encyclopadia Sinica " (weaving fascicle) that in June, 1984, Encyclopedia of China Publishing House published.Its principle is: sliver becomes filament through the licker-in shredding, utilizes air communication to cross aspiration channel (8) filament (10) is sent to the electrostatic field (3) that is produced by high voltage source (1), high-field electrode (2) and earth electrode (5) by fibre transportation pipe (9).Under the effect of high-voltage electrostatic field, fiber is pressed the power line direction and is arranged, and moves to the electric field center, is condensed into free end yarn (4), through twister (6) twisting resultant yarn (7), is drawn by delivery roller then, directly is wound into bobbin.
Electrostatic spinning method shortens technology, raising speed except having, add large package etc. and the same advantage of other novel spinning, and it also has yarn evenness even, and filoplume and cotton junction impurity are less, and fabric abrasion resistance can better be inhaled advantages such as the look performance is good.But, in above-mentioned electrostatic spinning device, free end yarn tail all is suspended between the electrode, when the twister high speed rotary, free end yarn tail is subjected to the influence of air ring and centrifugal force and turns round instability, it is not high to cause spinning speed to be carried, and its spinning speed is lower than 50 meters/minute, only is about a times of ring spinning.Compare with friction spun yarn with open-end spinning and to have a long way to go, this is the one of the main reasons that causes the electrostatic spinning economic benefit lower.External research in this respect has many patents, as on April 10th, 1974 the BP GB1349925 and the U.S. Pat 4040243 on August 9th, 1977 etc.Though device separately is all inequality, all there is a common problem, promptly free end yarn tail is suspended between two electrodes basically, it is not applied positive control.Like this, when high speed rotary, there is the unsettled situation of free end yarn tail equally.
The purpose of this invention is to provide a kind of high speed electrostatic spinning device that in electrostatic field, has control free end yarn tail apparatus.
Figure (2) is a side sectional view of the present invention.Electrostatic high-pressure power supply (1) is connected with high-field electrode (2) by high-voltage power-line, and high-field electrode (2) and earth electrode (8) constitute the high-voltage electrostatic field.The inner distance of two electrodes is 70～130 millimeters.The live part of this electrostatic field is completely enclosed within the interior space of first half case (3) and latter half of case (4).The profile of case (3) is approximate spheroid or sub-elliptical body.Its end is equipped with tapered electrode (2), its porose or atresia of central authorities; The other end links to each other with case (4), and a V-shaped groove piece (5) (it also can be made of one with case (4)) in the inwall embedding of case (4).V-shaped groove in the A-A cutaway view of figure (2) can be two planes or cambered surface (5(b), 5(c)) or several planes or cambered surface (5(b), 5(c), 5(e), 5(f)) form, its shape can be symmetric figure or asymmetry.V-shaped groove bottom line 5(d) near two center lines of electrodes and and the central axis of case (4) substantially parallel.V-shaped groove bottom line 5(d) length be the inboard top of two electrodes spacing from 50～80%, interregional a row or number exhausting hole 5(a arranged at this), through hole 5(a) cross sectional shape can be circular or other geometry, and the sectional area of each through hole is less than 8 square millimeters.An end and the earth electrode (8) of V-shaped groove piece (5) touch among the figure (2), and the other end and high-field electrode (2) maintain a certain distance.Earth electrode (8) is inlaid in the spinning organ case top cover (7), and there is through hole 8(a in central authorities), the surperficial 8(b of earth electrode (8)) can be convex surface, also can be the plane.Hole 5(a) communicate with air intake duct (6), air intake duct (6) and air intake duct (10) link to each other with the negative pressure source of the gas, and its flow and pressure can be distinguished and regulated.
During spinning, through the filament (12) after the shredding of high speed licker-in along the electric field region that enters spinning organ under the effect of fibre conveying channel (11) at inspiratory airflow, under effect of electric field, fiber is arranged along the power line direction and stretched, and is approximate parallel with the line of two electrode centers or keep an inclination angle.Fiber moves to the stronger zone of electric field (i.e. near zone the two electrode centers lines) because effect of electric field also makes, cohesion; Meanwhile, fiber also is subjected to suction hole 5(a) the attraction of inspiratory airflow gradually to V-shaped groove bottom cohesion, form free end yarn tail (13).The major part of free end yarn tail (13) is subjected to the holding of V-shaped groove, fraction is suspended from the space between V-shaped groove and the high-field electrode (2), free end yarn tail (13) is through the central through hole 8(a of earth electrode (8)), be drawn towards twister (9) and twist, twister is twisted sliver becomes yarn (14).
High-field electrode in the spinning organ of the present invention (2) and earth electrode (8) are manufactured with metal material, spinning organ case (3), (4), V-shaped groove piece (5), fibre transportation pipe (11), aspiration channel (6), (10), spinning organ case top cover (7) is manufactured with insulating materials.
Advantage of the present invention is the porose V-shaped groove device that has increased positive control and holding free end yarn tail in electrostatic field, has guaranteed that free end yarn tail is near the electric field center line all the time.This had both helped fibre deposition, also helped free end yarn tail high speed rotary stably, thereby suitable high-speed spinning.The spinning speed of this spinning organ can reach more than 100 meters/minute.
To the high speed electrostatic spinning device shown in the figure (2) with control free end yarn tail apparatus.When V-shaped groove by 5(b), 5(c) two planes form; V-shaped groove through hole 5(a) cross section is circular, and sectional area is about 3 square millimeters, V-shaped groove bottom line 5(d) length be the inboard top of two electrodes spacing from 60%; Very during convex, spinning speed can reach more than 100 meters/minute ground connection.
