Abstract

The invention relates to a device and a method technique for manufacturing melting electrostatic spinning nano-fiber non-woven fabrics. The device for manufacturing the melting electrostatic spinning nano-fiber non-woven fabrics comprises a material storage tank, a screw extruder, a filter, a measuring pump, a material path, a spinning component, a receiving device and a high-voltage electrostatic generator; and the material path is made of high thermal conductivity insulating ceramics. The method for manufacturing the nano-fiber non-woven fabrics adopts the device for manufacturing the same and comprises the following process steps: (1) preparing a polymer melt; (2) jetting nano-fibers; and (3) molding the non-woven fabrics. By adopting a melting electrostatic spinning technique, the method for manufacturing the nano-fiber non-woven fabrics avoids the pollution problem caused by a solution electrostatic spinning solvent, which is a novel environment-friendly technique for manufacturing the non-woven fabric; and the device is reconstructed on the basis of the conventional screw extrusion melting spinning production equipment to meet the requirement on production, has a low implementation cost, and is easy for industrialized popularization.

Description

technical field [0001] The invention relates to nonwoven fabric technology in the field of textiles, in particular to a manufacturing equipment and method for melt electrostatic spinning nanofiber nonwoven fabric. Background of the invention [0002] With the development of nanotechnology, electrospinning technology, as an effective and practical method for preparing nanofibers, has attracted increasing attention in the field of nanomaterials research. The patent on the electrospinning device first appeared in 1934 and was invented by Formhals [Formhals A. Process and apparatus for preparing artificial threads. USP, 1,975,504.], which makes the charged spinning solution or melt flow and deform in the electric field , and then solidified by evaporation of the solvent or cooling of the melt to obtain a fibrous nonwoven material. Nanofibers have fine structure, high porosity, excellent flexibility, adsorption, filterability, cohesion and thermal insulation. These excellent pro...
