Abstract

The invention discloses a centrifugal spiral spinning head and a centrifugal spiral spinning device employing the same. The centrifugal spiral spinning head comprises two parts, namely a hollow screw and a coaxial spiral blade which is connected with the hollow screw, wherein spinneret orifices are evenly formed in the outer edge surface of the spiral blade vertically to the axial direction; and when the screw rotates at a high speed, a feed liquid flows through the hollow screw under the action of centrifugal force, and is sprayed from the spinneret orifice in the tip of the spiral blade. According to the centrifugal spiral spinning device, the defects that existing centrifugal spinning equipment is complicated in structure, poor in air-tightness, and poor in spinning uniformity; and the actual requirements can be well met.

Description

technical field [0001] The invention belongs to the technical field of centrifugal spinning, and in particular relates to a centrifugal spiral spinning device. Background technique [0002] Centrifugal spinning and electrospinning are currently the two most important methods for preparing ultrafine fibers. The centrifugal spinning method is a method in which the polymer melt or solution is thrown out from the pores to form fibers by means of centrifugal force and shear force generated by a high-speed rotating device. Compared with the traditional electrospinning method, the production efficiency of the new centrifugal spinning nanotechnology is increased by about 1000 times, the cost is low, and the spinning efficiency is high. It can be used to prepare polymers, metals, ceramics, composite fibers, etc. With the development of science and technology, centrifugal spinning has been developed from the initial preparation of rayon to the present preparation of nanofiber membran...
