Preparation method and electret equipment of polypropylene melt-blown non-woven fabric

Abstract

The invention discloses a preparation method and electret equipment of a polypropylene melt-blown non-woven fabric. The preparation method includes the steps of melt-blowing production, pure water preparation, electret technology and drying technology. The preparation method has the advantages that more electrets can be generated by the aid of spunlace electret, electrodes lost in the spunlace electret process are made up, so that the non-woven fabric is better in permeability, the electrets are stable, retention time is long, adsorptivity is strong, good filtering effects can be achieved under the condition of low resistance, atomized water can be prevented from running off into a working environment by the aid of a splash-proof device, the working environment can be improved, pure waterafter puncture can be maximally recovered by the aid of a pure water recovery device, and the pure water is prevented from flowing to the outside.

Description

technical field [0001] The invention relates to the technical field of non-woven fabric production, and more specifically, relates to a preparation method of polypropylene melt-blown non-woven fabric and electret equipment thereof. Background technique [0002] Melt-blown non-woven fabrics are mostly used for air filtration and purification, and are widely used in masks, purifiers, fresh air systems, air filters, etc. Non-woven fabrics need to go through multiple processes during production, among which the quality of the electret process Will directly affect the quality of the product. [0003] The current electret process adopts the corona electret method, which produces less electret, low electrostatic adsorption strength, high voltage corona electret, ionized ozone affects the environment, and has a large risk factor. The effect is not ideal; the non-woven fabric is composed of countless tiny silk threads, and the arrangement of the threads is disorderly. This method on...

[0003] The current electret process adopts the corona electret method, which produces less electret, low electrostatic adsorption strength, high voltage corona electret, ionized ozone affects the environment, and has a large risk factor. The effect is not ideal; the non-woven fabric is composed of countless tiny silk threads, and the arrangement of the threads is disorderly. This method only uses electrodes and non-woven fabric electrets, which cannot physically dredge the non-woven fabric, resulting in poor permeability of the non-woven fabric. Poor, so a new electrification process is needed to improve the permeability of non-woven fabrics while improving the quality of electrification
