Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1-3, the utility model relates to a static electricity layer structure is imitated frequently, including superimposed in proper order: the electrostatic fabric comprises a first non-woven fabric layer 1, an electrostatic film layer 2, an electrostatic cotton layer 3 and a second non-woven fabric layer 4, wherein the electrostatic film layer 2 is provided with uniformly distributed through holes 21. Specifically, first non-woven fabrics layer 1 is for refusing the water non-woven fabrics, can prevent water infiltration downwards, right it plays the guard action to imitate the static layer structure often, second non-woven fabrics layer 4 is hydrophilic non-woven fabrics, and it has certain moisture absorbing's ability, and contact wearer's mouth nose portion has strengthened the travelling comfort of wearing behind the preparation gauze mask. In addition, the electrostatic cotton layer 3 is a melt-blown non-woven fabric, the fiber diameter of the electrostatic cotton layer is about 2um, the electrostatic cotton layer is one tenth of that of a spun-bonded layer, and the electrostatic cotton layer has an effective isolation effect on bacteria, viruses or blood infiltration. The utility model discloses added an electrostatic film layer 2 between first non-woven cloth 1 and the cotton layer 3 of static, this electrostatic film layer 2 is a normal effect static polymer film that takes, this polymer film's substrate can be for PE, PET, PP etc, and add the modifier in this substrate, make it have normal effect electrostatic action, can utilize the electric heat hair-dryer to supply the static charge to its heating after preserving promptly or using a period, make it resume static efficiency, and continue to transmit the static charge for the cotton layer 2 of static, make this normal effect electrostatic structure keep the long-term effectual effect of catching micronic dust particle or aerosol. After the static film layer 2 is added, the static charges generated by the static film layer are transmitted to the static cotton layer 3, so that the static cotton layer 3 has a static effect, the pre-electret treatment process of the static cotton layer 3 can be omitted, the production process is reduced, and the production efficiency is improved.
