Abstract

The invention discloses an electrospinning device for preparation of composite fibers. The electrospinning device comprises a first spinning component, a second spinning component, a first high-voltage electrostatic generator, a second high-voltage electrostatic generator, a conical water bath, a water bath circulating device and a fiber collecting roller. A high-voltage electrostatic field is formed between each of the first spinning component and the second spinning component and the conical water bath. The first and second spinning components spray different spinning solutions respectivelyto form different fiber filaments, and the two types of fiber filaments are mixed and fixed in the conical water bath and subjected to stretching and orientation to finally form high-performance composite fibers, and the generated composite fibers are collected on the fiber collecting roller.

Description

technical field [0001] The invention relates to the technical field of composite fiber preparation, in particular to an electrostatic spinning device for preparing composite fibers. Background technique [0002] Composite fiber refers to a fiber composed of two or more high polymers or polymers with different properties in a certain way along the fiber axis. Using composite fiber manufacturing technology can obtain a variety of modified fibers such as bicomponent fibers, permanently crimped fibers, ultrafine fibers, hollow fibers, and special-shaped fine fibers with the characteristics of two polymers. This type of fiber can combine the advantages of multiple components, such as polyester / nylon composite fiber, which not only has the advantages of good abrasion resistance, high strength, easy dyeing, and moisture absorption of nylon, but also has the advantages of good elasticity, high modulus, and fabric crisp and other characteristics. [0003] There are many methods for...
