DEVICE FOR PRODUCTION OF 2D OR 3D FIBRE MATERIALS FROM MICROFIBRES AND NANOFIBRES Russian patent published in 2015 - IPC D01D5/00 

FIELD: technological processes.

SUBSTANCE: device for production of 2D or 3D fibre materials from microfibres or nanofibres comprises a set of metal spinning nozzles (3), connected with the first potential, a set of electrodes (6) of a collector facing the set of nozzles (3), arranged at regular intervals and connected with the second potential, and a collecting plate (7) or a collecting cylinder (14) for collection of microfibres or nanofibres laid between pairs of adjacent electrodes (6) of the collector. The substance of the invention consists in the following: a set of collector electrodes (6) comprises at least two electrodes (6) of the collector, arranged in one plane, and the collecting plate (7) on the line of its crossing or along the tangent to the collected cylinder (14), which is perpendicular to the line of contact with the plane of the collector electrodes (6), forming with the plane of the collector electrodes (6) an angle α in the range between 0° and 90°, at the same time the collecting plate (7) or the collecting cylinder (14) may move relative to the electrodes (6) of the collector in the direction in the plane that is perpendicular to the plane of collector electrodes (6), and where the axis of the electrode (6) lies in direction of movement of the collecting plate (7) or the collecting cylinder (14), forming with the axis of this electrode (6) the angle β, the value of which lies between 0° and 90°.

EFFECT: device makes it possible to create large flat and volume objects from ordered nanofibres.
