Nanofiber yarn preparation device and method

Abstract

The invention relates to a nanofiber yarn preparation device. A motor is horizontally placed, and a rotating shaft of the motor drives a spinneret device to rotate around the shaft through a coupler;the spinneret device is electrically connected with the positive electrode of an electrostatic generator; a bundling mechanism comprises a bundling device, a fan and at least two air showing heads, and the fan communicates with the air showing heads; the air showing heads are uniformly arranged around the rotating shaft of the motor; the bundling device adopts a tubular conductive body and is electrically connected with the negative electrode of the electrostatic generator; the central axis of the bundling device, the central axis of a spinneret plate of the spinneret device and the central axis of the rotating shaft of the motor are on the same straight line; and a winding collecting mechanism comprises a yarn guiding roller and a winding roller, wherein the yarn guiding roller is locatedon one side of the bundling device. The nanofiber yarn preparation device provided by the invention only comprises three simple main body parts, and the nanofiber is prepared by adopting an electrostatic centrifugal spinning method; and the device is simple in structure, convenient to operate, high in production efficiency, wide in raw material source selection range, wide in raw material source,low in energy consumption and high in energy conservation.

Description

technical field [0001] The invention relates to the field of textile equipment and methods, in particular to a nanofiber yarn preparation device and method. Background technique [0002] Due to its small fiber size, nanofibers have a variety of properties due to quantum effects. They have unique optical, thermal, electrical, and magnetic properties. In addition, they also have the characteristics of performance modification. There are good applications, so it has attracted wide attention. [0003] At present, spinning processing method is currently the most promising processing method, generally including electrospinning method, two-component composite spinning method, melt blown method and so on. However, since the nanofibers prepared by the usual spinning processing method are collected in the form of non-woven fabrics, their mechanical strength is poor, and they cannot meet the application occasions with higher mechanical strength. At present, the research on nanofiber ...
