Embodiment 1
[0093] Embodiment 1: a kind of high-efficiency dust-proof mask is used filter layer body structure:
[0094] The present embodiment provides a filter layer body for a high-efficiency dust-proof mask, which has a structure comprising the following layers arranged in sequence from outside to inside:
[0095] Non-woven outer layer, which is 30g / m 2 non-woven fabric layer;
[0099] Pure cotton gauze inner layer, it comprises 2 layers, and described pure cotton gauze grammage is 40g / m 2 .
[0100] Specifically, the aloe mannan porous film layer described in this example was prepared through the following steps:
[0101] 1) Take aloe mannan powder and ultrapure water according to the ratio of 1.5:100;
[0102] 2) Place the aloe mannan solution in a constant temperature water bath at 44°C, and stir with a magnetic stirrer at 500r / min for 60min;
[010...
Embodiment 2
[0132] Embodiment 2: another kind of high-efficiency dustproof mask is used filter layer body structure:
[0133] The present embodiment provides another kind of filter body structure for high-efficiency dust-proof masks, which is basically the same as Embodiment 1, except that the filter layer structure of the present embodiment does not contain aloe mannan porous film layer; the remaining structures And method are all identical with embodiment 1.
Embodiment 3
[0134] Embodiment 3: Another kind of high-efficiency dustproof mask is used filter layer body structure:
[0135] The present embodiment provides another filter layer body structure for a high-efficiency dustproof mask, which is basically the same as Embodiment 1, except that the filter layer body structure of the present embodiment does not contain a composite filter layer; all the other structures and methods are the same as Example 1 is the same.

Abstract
The invention relates to the technical field of new materials and especially relates to a high-effective filter layer body for a dust mask, wherein the filter layer body includes the following structures arranged successively from exterior to interior: a nonwoven outer layer; an aloe mannan porous membrane layer; a composite filter layer; an aloe mannan nanoporous inner membrane layer; and a pure-cotton gauze inner layer. The composite filter layer is formed by blend-weaving main yarn and sub-yarn, wherein modified coffee charcoal/polycarbonate composite coffee charcoal fibers are subjected totreatment with a copper salt treating agent, and treatment with a functional negative oxygen ion additive solution to obtain the composite coffee charcoal fibers as the main yarn, and allyl hydantoinnanofibers are the sub-yarn. In the application, the filter layer body is high-effective in dust removal, and has beneficial electromagnetic effects of irradiating far-infrared ray, shielding electromagnetic wave, eliminating static electricity, preventing ultraviolet ray and the like, and can be applied to special application fields such as high-altitude cold regions, large electromagnetic radiation places, etc.
Description
technical field [0001] The invention relates to the technical field of new materials, in particular to a filter layer body for a high-efficiency dustproof mask. Background technique [0002] With the rapid development of the science and technology industry, various industrial processes such as power generation, metallurgy, petroleum, chemical, textile printing and dyeing, heating, and cooking processes will emit a large amount of smoke and dust. Exhaust gas is also emitted into the atmosphere when fuel is used. Therefore, in recent years, smog weather often occurs in all parts of the country, especially in first-tier cities such as Beijing and Nanjing. That is, there are many fine particles in the air, also known as fine particles, fine particles, and PM2.5 , can be suspended in the air for a long time, and the higher its concentration in the air, the more serious the air pollution. PM2.5 has small particle size, large area, strong activity, and is easy to be accompanied by...
