Background
The non-woven fabric is also called non-woven fabric, and has the advantages of air permeability, light weight, no toxicity, no irritation, low price and the like. The non-woven fabric is one of the main fabrics of the mask, and the common mask is composed of three layers: the outer non-woven fabric layer and the inner non-woven fabric layer (hereinafter referred to as non-woven fabrics) are used for adsorbing large-particle dust, small-particle dust, bacteria and viruses need to be adsorbed through the melt-blown fabrics, and the core adsorption material of the mask is the melt-blown fabrics. However, since the productivity of meltblown is much lower than that of non-woven fabrics and the meltblown is more expensive than non-woven fabrics, meltblown is preferentially supplied to medical-grade masks. The inventor designs a high-adsorption skin-friendly hot air non-woven fabric which is good in adsorption effect and suitable for common dustproof and haze-preventing masks.
SUMMERY OF THE UTILITY MODEL
Therefore, to foretell problem, the utility model provides an adsorption effect is good, is applicable to the hot-blast non-woven fabrics of the close skin of high absorption of ordinary dustproof antifog haze gauze mask.
In order to achieve the above purpose, the utility model adopts the following technical scheme: a high-adsorption skin-friendly hot air non-woven fabric comprises an outer hot air non-woven fabric layer, an absorption core layer and an inner hot air non-woven fabric layer which are sequentially compounded from top to bottom, wherein the absorption core layer comprises a fluffy cotton layer, a plurality of first activated carbon fiber layers which are parallel to each other are arranged on the upper surface of the fluffy cotton layer at equal intervals, and an upper surface ventilation area is an area, between every two adjacent first activated carbon fiber layers, of the upper surface of the fluffy cotton layer;
a second activated carbon fiber layer is arranged on the lower surface of the fluffy cotton layer and is arranged under the upper surface breathable areas;
the orthographic projection area of the second activated carbon fiber layers on the plane of the lower surface of the fluffy cotton layer covers the upper surface breathable areas, and the area of the lower surface of the fluffy cotton layer between two adjacent second activated carbon fiber layers is a lower surface breathable area.
Furthermore, the fluffy cotton layer has bulkiness larger than that of the outer hot air non-woven fabric layer and the inner hot air non-woven fabric layer.
Furthermore, hot melt adhesive points are bonded on the surface of the first activated carbon fiber layer, and the first activated carbon fiber layer is bonded with the upper surface of the fluffy cotton layer through the hot melt adhesive points.
Furthermore, hot melt adhesive points are bonded on the surface of the second activated carbon fiber layer, and the second activated carbon fiber layer is bonded with the lower surface of the fluffy cotton layer through the hot melt adhesive points.
By adopting the technical scheme, the beneficial effects of the utility model are that: this high hot-blast non-woven fabrics of close skin that adsorbs dust, haze are effectual, are applicable to the antifog haze gauze mask of ordinary dustproof of production. Specifically, the first activated carbon fiber layer and the second activated carbon fiber layer are respectively arranged on the upper surface of the fluffy cotton layer in a staggered mode, and the first activated carbon fiber layer and the second activated carbon fiber layer have air permeability which is inferior to that of an outer hot air non-woven fabric layer, the fluffy cotton layer and an inner hot air non-woven fabric layer. The area, between two adjacent first activated carbon fiber layers, of the upper surface of the fluffy cotton layer is an upper surface breathable area, and during breathing, large-particle dust and haze are adsorbed in the air through an outer hot air non-woven fabric layer; after air penetrates through the hot air non-woven fabric layer, a small part of air penetrates through the first activated carbon fiber layer, and small particle dust and haze in the air are adsorbed by the first activated carbon fiber layer; most of the air penetrates through the upper surface breathable area of the fluffy cotton layer, the air transversely flows to the lower surface breathable area of the fluffy cotton layer in the fluffy cotton layer, and small particle dust in the air is adsorbed by the fluffy cotton layer and the second activated carbon fiber layer. This high absorption close skin hot-blast non-woven fabrics has fine adsorptivity to the gas permeability is good.

fig. 2 is an exploded view of an embodiment of the present invention.
Detailed Description
The present invention will now be further described with reference to the accompanying drawings and detailed description.
Referring to fig. 1 and 2, the present embodiment provides a high-adsorption skin-friendly hot-air non-woven fabric, which includes an outer hot-air non-woven fabric layer 1, an absorption core layer, and an inner hot-air non-woven fabric layer 3, which are sequentially combined from top to bottom. The absorption core layer comprises a fluffy cotton layer 2, and a plurality of first activated carbon fiber layers 4 which are parallel to each other are arranged on the upper surface of the fluffy cotton layer 2 at equal intervals; specifically, the surface of each first activated carbon fiber layer 4 is bonded with a hot melt adhesive point (not shown in the figure), and the first activated carbon fiber layer 4 is bonded with the upper surface of the fluffy cotton layer 2 through the hot melt adhesive point. The area of the upper surface of the fluffy cotton layer 2 between two adjacent first activated carbon fiber layers 4 is an upper surface breathable area 21.
And a second activated carbon fiber layer 5 is arranged on the lower surface of the fluffy cotton layer 2 corresponding to the position under each upper surface breathable area 21. The surface of the second activated carbon fiber layer 5 is bonded with hot melt adhesive dots (not shown in the figure), the second activated carbon fiber layer 5 is bonded with the lower surface of the fluffy cotton layer 2 through the hot melt adhesive dots, the orthographic projection area of the second activated carbon fiber layer 5 on the plane of the lower surface of the fluffy cotton layer 2 covers each upper surface ventilation area 21, and the area of the lower surface of the fluffy cotton layer 2 between two adjacent second activated carbon fiber layers 5 is a lower surface ventilation area 22.
