Embodiment 1

[0043] figure 2 For each layer of the mask shown, the first non-woven fabric layer 2 and the second non-woven fabric layer 4 all adopt a grammage of 30-50g / m 2 Polypropylene non-woven fabric, melt-blown non-woven fixed layer with a grammage of 15g / m 2 Polypropylene non-woven fabric, the bionic composite micro-nano fiber layer adopts a weight of 70-80g / m 2 The activated carbon fiber cloth is composited with the spun fiber layer by electrospinning for 1.0h, with an average weight of 19.1g / m 2 , The spinning dope uses polyacrylonitrile. Prepare each layer according to figure 2 The sequence shown is stacked together, and the stacking and compounding method can adopt a conventional compounding method in the field of textiles, such as a thermal bonding method. The sealing method is a zipper, such as image 3 , Figure 4 .

Embodiment 2

[0045] figure 2 For each layer of the mask shown, the first non-woven fabric layer 2 and the second non-woven fabric layer 4 all adopt a grammage of 30-50g / m 2 Polypropylene non-woven fabric, melt-blown non-woven fixed layer with a grammage of 15g / m 2 Polypropylene non-woven fabric, the bionic composite micro-nano fiber layer adopts a weight of 70-80g / m 2 The activated carbon fiber cloth is composited with the spun fiber layer by electrospinning for 1.0h, with an average weight of 19.1g / m 2 , The spinning dope uses polyacrylonitrile. Prepare each layer according to figure 2 The sequence shown is stacked together, and the stacking and compounding method can be a conventional compounding method in the textile field, such as knitting and sewing. The sealing method is Velcro, such as Figure 5 , Figure 6 .

[0046] Except that the filter element of the mask of the present invention cannot be reused, the mask main body can be repeatedly cleaned and used for multiple times...

Abstract

A filter-element-replaceable type mask with adsorption and filtration functions comprises a mask body. A first non-woven fabric layer, a replaceable filter element layer and a second non-woven fabric layer are stacked from the outer surface to the inner layer of the mask body in sequence. The mask body is provided with a zipper or a hook-and-loop fastener, adjustable fixing belts are arranged on the two sides of the mask body, the replaceable filter element layer is made of bionic composite micro-nano fiber with the adsorption and filtration functions and comprises a spinning fiber layer and an activated carbon fiber layer, and the surface of the replaceable filter element layer is wrapped and fixed through two melt-blow non-woven fabric fixing layers. A filter element with the adsorption and filtration functions is arranged, the spinning fiber material layer can effectively filter fine particulate matter in air inhaled by the human body, meanwhile, the activated carbon cloth layer can adsorb various pollutants of the inhaled air, the hurt to the human body from harmful substances is relieved, the filter element can be replaced, operation is easy and convenient, meanwhile, the mask body can be cleaned and used repeatedly, and environmental friendliness and economization are achieved.

Description

technical field [0001] The invention relates to a novel mask with dual functions, in particular to a mask with dual functions of adsorption and filtration and a replaceable filter element, which belongs to the field of daily life protective articles. Background technique [0002] Nowadays, the problem of air pollution is becoming more and more serious, especially the smog pollution that has appeared in recent years is very serious. In some northern cities, such as Beijing, Tianjin, Shijiazhuang, etc., the PM2.5 monitoring results in 2013 show the number of days with good air quality throughout the year. The air quality in Hangzhou, Ningbo and other places is also showing a serious downward trend. The current priority is not only to find effective air treatment methods, but also to find green and efficient self-protection methods. And the use of mask shows its effect aspect people's protection in daily life. However, most of the anti-smog masks on the market are disposable,...
