Electrostatic melt spinning device

Abstract

An electrostatic melt spinning device comprises an upper nozzle and a lower nozzle. An upper-nozzle inner barrel is formed in the upper nozzle, a lower-nozzle inner barrel is formed in the lower nozzle, and a liquid core pipeline penetrates the upper nozzle and the lower nozzle; a concave and convex anti-adhesion structure is arranged on inner walls of parts connected with a molten polymer in spinning, and an anti-adhesion function of a polymer melt in spinning assemblies can be achieved; the function mechanism of the concave and convex anti-adhesion structure lies in that the concave and convex anti-adhesion structure includes concave parts and convex parts, the convex parts are arranged in a manner of protruding internal surfaces of the parts, direct contact of the polymer melt with highadhesion and internal walls of the parts is reduced by the aid of supporting among points, a gas suspension function is formed under the action of the high-temperature high-pressure melt, and self-separated anti-adhesion is achieved.

Description

technical field

[0001] The invention relates to the technical field of textiles, in particular to a novel melt electrostatic spinning device. Background technique

[0002] The earliest record of the melt spinning process comes from a British patent in 1845. In 1939, melt spinning was industrialized as a production process for the manufacture of nylon 66 fibers. Such as figure 1 As shown, the basic process of melt spinning includes melting of materials, extrusion from the micropores of the spinneret, and cooling and solidification of melt streams. The finished filament can be wound into a bobbin or otherwise processed. In the process of melt spinning, the polymer is fed into the extruder, conveyed by the screw, plasticized, melted and then forwarded to the metering accumulator: the metering polymer ensures that the melt of the polymer can flow stably and evenly into the In the spinning assembly of the key component, the melt in the spinning assembly is filtered by the fil...
