Problems solved by technology

During centrifugal spinning, the spinning head is driven by a motor to rotate, and the spinning solution is ejected from the spinneret hole of the spinning head, and moves between the spinneret hole and the collecting rod to be stretched, and at the same time, the solvent volatilizes to form fibers, which pass through The fiber film is received by the collecting rods; in this collection method, the spinning is fixed between the collecting rods, and the fibers obtained are discontinuous short fibers, which are inefficient and cannot achieve continuous production
[0005] The patent with the application number CN201820388681.7 provides a centrifugal electrospinning device, including a centrifugal spinning nozzle, a receiving device arranged above the multifilament nozzle, a driving mechanism for driving the centrifugal spinning nozzle, and a A power supply device for forming an electrostatic field required for spinning solution between the centrifugal spinning nozzle and the receiving device, the centrifugal spinning nozzle is provided with several outlet holes radially spaced from each other, the centrifugal spinning nozzle and the receiving device The spinning solution delivery device is connected; in this device, the receiving device is set above the centrifugal spinning nozzle and grounded, and the spinning jet from the centrifugal spinning nozzle is stretched under the action of centrifugal force and electric field force. This electrostatic method not only cannot realize continuous Generated, and there are problems of excessive energy consumption, low operability, and low safety factor

Abstract

The invention discloses a plane-receiving centrifugal spinning device. In the invention, a continuously moving collection belt is arranged under the spinneret. After adjusting a suitable height, the spinning solution sprayed out by the spinneret when rotating at a high speed instantly forms fibers. And it descends in a spiral line and collects on the collection belt, finally forming a continuous centrifugal spinning fiber web; the invention solves the problem of preparation of continuous centrifugal spinning filaments, realizes the batch production of centrifugal spinning, and is applicable to wide-width nonwovens Production of composite or wide nanometer or submicron scale nonwovens with surface nanofibers or submicron fibers.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a plane-receiving centrifugal spinning device. Background technique [0002] Centrifugal spinning is a new spinning technology that can be applied to both solution spinning and melt spinning. Centrifugal spinning In the spinning process, the spinning solution inside the spinneret is ejected from the micropores by the centrifugal force generated by the high-speed rotating spinneret to form long and thin fibers. The materials that can be prepared include inorganic materials and polymers. Materials, combined with the characteristics of high output of centrifugal spinning and the advantages of fiber products, the fiber products prepared by it can be used in biomedicine, air filtration, energy and other fields. [0003] At present, for centrifugal spinning, the forming mechanism of its fibers has been deeply studied, and the technical problem to be solved is how to realize the conti...
