Magnetic-spinning core-spun composite yarn

Abstract

The invention discloses a magnetic-spinning core-spun composite yarn. The yarn comprises a filament located at a core part and a polymer coating layer located on the outer peripheries of the core part, wherein the polymer coating layer is a magnetic polymer nanometer coating layer; and the magnetic polymer nanometer coating layer coats the filament located at the core part through magnetic spinning of magnetic spinning equipment. During spinning of the yarn, electric field force is replaced by magnetic field force; nano fibers are prepared through stretching of a polymer spinning solution under alternating magnetic field force, and the surface of the filament is coated by the polymer nano fibers. In this way, strength of the nano fibers is greatly improved, and the application scope is expanded greatly.

Problems solved by technology

[0003] Electrospinning is mainly used to prepare fiber membranes in the form of non-woven fabrics, and most of its products exist in the form of films or similar films. Therefore, the strength of electrospun nanofibers is generally not high. Due to the low strength of electrospun nanofibers, it can be used in practice hindered in the application of

In addition, there are still the following technical problems in the preparation of nanofibers by electrospinning: electrospinning requires a high spinning voltage to form an electric field, and this voltage is usually as high as tens of thousands to hundreds of thousands of volts. Continuous use will cause potential danger, and such high voltage and high electric field are likely to break down and increase the risk of other equipment
