Problems solved by technology

However, the traditional electrostatic adsorption paper has certain defects. First, the electrostatic dust removal effect is good at the beginning of use, but the electrostatic dust removal effect is poor in the later stage; second, the static electricity is easy to disappear, and the dust particles are easy to transfer, which is easy to cause secondary dust pollution; It needs to be electrified by friction, and the scope of use is limited. It is often used with an electrostatic dust removal mop, and it cannot even produce the effect of electrostatic adsorption.
[0005] Chinese patent document CN 208928752 U discloses a kind of electrostatic dedusting paper, adopts the electrostatic adhesion coating on one end surface of the spunlace non-woven fabric, and the other end surface is provided with a sticker layer, adsorbed by the electrostatic adhesion coating Fine particles of dust adhere to paper particles, cloth particles and large particles of dust through the stickiness of the surface of the sticker layer, achieving the effect of not only removing fine particles of dust, but also removing paper particles, cloth particles and large particles of dust The purpose is to realize the removal of paper particles, cloth particles and large particle dust, improve the dust removal effect, and solve the problem that the electrostatic dust removal paper cannot remove paper particles, cloth particles and large particle dust, which affects the dust removal effect technical problem
[0009] When the above-mentioned fiber electret and negative ion fiber are applied to the process of preparing negative ion electrostatic dust removal paper, the two will affect each other, especially the electrostatic voltage of the electret will be significantly reduced, and the added fiber will significantly affect the paper strength and other indicators
