Device for preparing non-woven fabric product continuously with electrostatic spinning method

Abstract

The invention relates to a device for preparing non-woven fabric products continuously with an electrostatic spinning method, belonging to the field of electrostatic spinning, and mainly comprising a melt body conveying device, a melt body metering pump, an electrostatic spinning die head, a die head temperature control device, a high-voltage static electricity generating device, a collecting device and a bracket, wherein the melt body conveying device is connected with an inlet of the melt body metering pump directly; an outlet of the melt body metering pump is connected with the electrostatic spinning die head; the die head temperature control device is arranged on the electrostatic spinning die head or distributed in the electrostatic spinning die head; the inner part of the electrostatic spinning die head is provided with a distributing passage; the distributing passage distributes a stream of melt body as a plurality of melt bodies uniformly; a spinneret plate of the terminal end of a plurality of the melt bodies is connected with a jet nozzle; the jet nozzle is not a single micro-hole but a hole-slot on a slit; and a passage of hot air is arranged at the outer part of the electrostatic spinning die head. According to the structure of the invention, the manufacturing difficulty of the electrostatic spinning die head is reduced greatly; the fiber diameter is much thinner than that of fiber manufactured by a melt blown method; the fiber quality is better; and modularization production is easy to realize.

Description

technical field [0001] The invention relates to a device for preparing superfine fibers by an electrostatic spinning method, belonging to the field of electrostatic spinning. Background technique [0002] Electrospinning is also called electrospinning. As early as 1930, the US patent US1975504 had reported the electrospinning method. In 1993, this technology was defined as electrospinning technology. In recent years, with the heating up of nanotechnology, electrospinning technology has become one of the most popular research fields today. At present, more than 50 kinds of polymers have been successfully prepared by electrospinning to produce ultra-fine fibers, and the diameter of the obtained fibers is generally Between tens of nanometers and 1 μm, the smallest diameter can reach 1nm. The principle of electrospinning can be briefly described as, in a high-voltage electrostatic field, the polymer solution or melt forms a thin stream from the end of the capillary to the recei...
