Device for continuously and efficiently forming yarn from reinforced nanofiber and spinning method

Abstract

The invention relates to the technical field of textile processing, and aims to provide a device for continuously and efficiently forming yarn from reinforced nanofiber and a spinning method. The device comprises a vertically installed motor, and a rotating shaft at the bottom of the motor is connected with a spinneret through a coupler; a plurality of spinneret holes are uniformly distributed inthe circumferential direction of the spinneret; after the collected yarn is led out from a fixed yarn drum, the yarn sequentially passes through a twister and an untwister and is wound into a spool bya winding roller; a conductive plate is arranged below the collected yarn between the twister and the untwister in parallel, and is perpendicular to the rotating shaft of the motor; the conductive plate is connected to the negative electrode of an electrostatic generator through a cable; the spinneret made of metal is connected to the positive electrode of the electrostatic generator through a cable, so that the spinneret and the spinneret holes have electrical conductivity; the collected yarn is subjected to rough modification and charge addition treatment. The nanofiber in the method is obtained through an electrostatic centrifugal spinning method, and the preparation efficiency is high; the spinning raw materials are soluble and meltable, the conductivity requirement of a spinning solution is not high, the selectivity is higher, and the yield of the nanofiber yarn is high.

Description

technical field [0001] The invention belongs to the technical field of textile processing, and in particular relates to a device and a spinning method for continuously and efficiently strengthening nanofiber yarns by means of electrostatic centrifugal spinning. Background technique [0002] Due to the size effect of nanofibers endowing them with special properties, they can be applied in the fields of biomedicine, energy materials, filter materials and sensors, and have 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. [0003] At present, the main preparation methods of nanofibers include chemical methods, phase separation methods, self-assembly methods and spinning processing methods. Spinning processing method is considered ...
