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.

Description

technical field [0001] The invention relates to a magnetic spinning core-spun composite yarn, in particular to a nanofiber core-spun composite yarn prepared by magnetic spinning equipment. Background technique [0002] Electrospinning is currently one of the simplest and most efficient methods for preparing polymer nanofibers. Due to its advantages such as simple processing equipment, wide source of raw materials, and controllable spinning process, electrospinning nanofibers have ultra-high specific surface area, high The characteristics of porosity and strong adsorption can be widely used in the fields of filtration, photocatalysis, sensors and biological applications. [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 ...
