An emulsion electrospinning process for the production of new high-performance fiber materials

Abstract

The invention discloses an emulsion electrospinning process for the production of new high-performance fiber materials, which specifically includes the following steps: S1, selecting the required functional drug and the main polymer, and respectively combining the functional drug and the main polymer with the corresponding The solvent is dissolved; S2, the functional drug solution prepared in step S1 and the main polymer solution are mixed and emulsified in sequence; S3, the emulsion prepared in step S2 is electrospun through an anti-blocking electrospinning device, and the present invention relates to a new The field of material processing technology. The emulsion electrospinning process for the production of new high-performance fiber materials can realize the use of a heating and lubricating nozzle structure and hot air drying in the entire spinning chamber to avoid the formation of wet spinning breakage and dry nozzle blocking In order to reduce the labor intensity of the production personnel, the high degree of automation reduces the workload of the production personnel.

Description

technical field [0001] The invention relates to the technical field of new material processing, in particular to an emulsion electrospinning process for the production of new high-performance fiber materials. Background technique [0002] High-performance fibers generally refer to fibers with a strength greater than 17.6cN / dtex and an elastic modulus above 440cN / dtex. High-performance fibers are a new generation of high-strength, high-modulus, and high-temperature-resistant fibers developed by the fiber science and engineering community. Synthetic fibers, high-performance fibers have special properties that ordinary fibers do not have. They are mainly used in military and high-tech industries. Most high-performance special fibers are made by wet spinning. Some fibers are difficult to prepare and require emulsion Spinning, reaction spinning, liquid crystal spinning, dry-jet wet spinning, phase separation spinning, high-voltage electrospinning, high-speed airflow melt-jet or s...

Problems solved by technology

[0010] Aiming at the deficiencies of the prior art, the present invention provides an emulsion electrospinning process for the production of new high-performance fiber materials, which solves the problem that the existing emulsion electrospinning device cannot significantly air-dry the ejected fiber filaments, and still It is necessary to carry out cumbersome deployment and control of the ingredients to ensure the spinning effect. At the same time, the overall environmental control is carried out in a single way, and it is easy to ignore the problem of dryness and blockage at the outlet of the nozzle. At the same time, when the existing emulsion electrospinning equipment is receiving materials, Most of them directly pile up the sprayed spinning in disordered layers on the material receiving plate under the nozzle. After the spinning is finished, they are wound into coils for the next process production. The degree of automation is low, which increases the work of production personnel. Burden, cannot realize the automatic anti-break winding directly after the spinning is completed, to reduce the labor intensity of the production personnel, and cannot achieve the purpose of fast and efficient spinning production
