Abstract

The invention relates to the technical field of textile processing and aims to provide a continuous preparation device and method for self-twisting nanofiber yarns. Including: a vertically installed motor, the rotating shaft at the bottom of which is connected to a metal spinneret through a coupling; multiple spinneret holes are evenly arranged along the circumference of the spinneret; the cluster system includes a funnel-shaped cluster, a fan and at least Two air shower heads; the funnel-shaped cluster is connected to the negative electrode of the electrostatic generator through a cable; a through hole is arranged in the center of the sinking part, and the through hole, the spinneret and the motor shaft are located on the same vertical axis; the spinneret The plane where each spinneret hole is located is arranged parallel to the plane part of the funnel-shaped cluster; the winding collection system includes a yarn guide roller and a winding roller, and the yarn guide roller is located below the through hole of the funnel-shaped cluster. In the present invention, the nanofibers are prepared by electrostatic centrifugal spinning, the production efficiency is high, and the raw materials are soluble and fusible; the nanofiber yarns integrate high degree of orientation, good continuity, synchronous twisting and efficient short process.

Description

technical field [0001] The invention belongs to the technical field of textile processing, and in particular relates to a device and method for continuously preparing self-twisting nanofiber yarns using electrostatic centrifugal spinning technology. Background technique [0002] Nanofibers have the characteristics of surface effect, small size effect, quantum size effect, quantum tunneling effect, high surface activity and high porosity, have excellent optical, thermal, electrical and magnetic properties, and can be flexibly modified for functional modification. It has great application potential in high-efficiency filtration, biomedicine, smart sensors and other fields, so it has received extensive attention. If nanofibers can be further processed into yarns that can meet modern textile processing, so as to process various functional fabrics and fabrics, it will inevitably break through the performance of traditional textiles and greatly increase the added value of products...
