Description

technical field [0001] The invention belongs to the field of nanofiber production equipment, in particular to an electrostatic spinning machine for preparing nanofibers with high adsorption performance. Background technique [0002] Nanofiber refers to a thread-like material with a diameter of nanoscale and a large length with a certain aspect ratio. In addition, fibers that are modified by filling nanoparticles into ordinary fibers are also called nanofibers. In a narrow sense, the diameter of nanofibers is between 1nm and 100nm, but in a broad sense, fibers with a diameter of less than 1000nm are called nanofibers. Nanofibers have a wide range of uses, such as implanting nanofibers into the surface of the fabric, a stable gas film can be formed to make an amphiphobic interfacial fabric, which can not only waterproof, but also prevent oil and dirt; made of nanofibers Advanced protective clothing, the fabric is porous and has a membrane, which not only allows air to pass th...

AI Technical Summary

Problems solved by technology

In the prior art, when the fiber filaments fall on the ground and then the fiber filaments are conveyed in the former, there are often chaotic knots between the fiber filaments, which affects the winding quality and efficiency of the fiber filaments; When the fiber is conveyed, there is no buffer stage between the fiber and the transfer roller, and the fiber is likely to generate a large stress, which is easy to cause the fiber to break

The winding quality of fiber filaments is poor, and the system operation stability is poor
