Abstract

The invention relates to a preparation device for micro-nanofibers, and aims to provide a spinning device for preparation of micro-nanofibers. The spinning device comprises a collection system, a spinning system and a continuous feeding system, wherein the spinning system comprises a motor, an insulating coupling and a spinner; rotating shafts of the motor and the spinner are both vertically mounted and connected through the insulating coupling; the main body of the spinner is hollow, and a spinning solution inlet is formed in the upper part of the spinner; a plurality of dispense needles are arranged outside the main body of the spinner in a surrounding manner and communicated with the interior of the spinner through connecting pieces. The spinning device can effectively collect fibers, more equipment can be arranged on a limited field, continuous production can be realized, and the production efficiency is improved; the thickness uniformity of fibrous membranes can be effectively adjusted, the content of beads of an obtained micro-nanofiber web is greatly reduced, and the electrostatic function contributes to improvement of the mechanical property of the fibers.

Description

technical field [0001] The invention relates to a preparation device for micro-nano fiber materials, in particular to a technology for preparing micro-nano fibers by centrifugal force spinning and collecting the micro-nano fibers in combination with electrostatic force. Background technique [0002] At present, the main technologies for preparing micro-nanofibers include self-assembly method, template synthesis method, phase separation method, melt blowing method, electrospinning method and centrifugal spinning method. Among them, electrospinning has attracted extensive attention from researchers due to its simple device, wide range of spinnable raw materials, and excellent fiber properties. However, with the deepening of the research, the requirement on the polarity of the spinning solution and the extremely low yield have gradually become the main barriers restricting the large-scale application of electrospinning. Judging from the current research status, it is difficult...
