Problems solved by technology

However, the output of single-nozzle electrospinning machines is very low and cannot be used in industrial production, while the prices of multi-nozzle electrospinning machines and spider-type electrospinning machines are too expensive for general enterprises to afford
In addition, the control of product quality indicators such as spinning process and fiber diameter is far from meeting the requirements of industrialization

Abstract

The invention discloses an airflow rotary table spinning device used for preparing nanofiber. The airflow rotary table spinning device comprises a feeding system, an air supply system and a spinneret system, wherein the feeding system comprises a screw rod extrusion machine or a spinning solution feeder, a metering pump and a spinning flux or solution distribution flow channel; the air supply system comprises an air compressor, an air storage tank, an air supply pipeline and an air affluence cavity; the spinneret system comprises a spinneret rotary plate, a motor and a collector, a middle shaft of the spinneret rotary plate is of a double-layer hollow structure, and a mandrel which drives the spinneret rotary plate to rotate under the action of the motor is arranged on the innermost layer of the middle shaft; multiple spinneret holes uniformly distributed are formed in the spinneret rotary plate in the circumferential direction and the periphery of each spinneret hole is surrounded by annular airflow spray nozzles. The airflow rotary table spinning device can prepare the nanofiber and the yield is obviously higher than that of electrostatic spinning.

Description

technical field [0001] The invention belongs to the field of textiles, in particular to an air-flow rotary disk spinning device for preparing nanofibers. Background technique [0002] In recent years, due to the diameter of nanofibers reaching the nanometer scale, the specific surface area is large, and the small size effect, surface effect, quantum size effect and macroscopic quantum tunneling effect are very significant. The application fields of its products are quite extensive, such as tissue regeneration scaffolds, high-capacity storage Hydrogen materials, micro-sensors, biochemical protective clothing, sound-absorbing materials, filter materials that can filter out SARS virus and anthrax and other germs, etc. [0003] Melt-blown nonwoven technology is the main method of preparing ultra-fine fibers, which uses high-speed and high-temperature airflow to stretch polymer melt into ultra-fine fibers. However, the diameter of meltblown ultrafine fibers is generally 1 to 5 μ...
