Embodiment Construction

[0031] The present invention will now be further described with reference to the drawings and specific embodiments.

[0032] The embodiment of the present invention is:

[0033] reference figure 1 As shown, an adsorption-enhanced filter material includes a filter material body 1, which includes a first fiber filament material and a second fiber filament material divided by a high melt index polypropylene resin, respectively connected by two meltblown molds The first fiber filaments 21 and the second fiber filaments 22 with different diameters are formed by spraying. The first fiber filaments 21 and the second fiber filaments 22 are randomly arranged to form a fiber network structure, and then reinforced by mechanical, thermal bonding or chemical methods, preferably The chemical method is used to make the subsequent formation of a non-woven fabric with roughness on the surface, the groove of which can maintain the original structure, and the space formed by the first fiber filament ...

Abstract

The invention relates to an adsorption-enhanced filter material. The problem that in the prior art, the adsorption effect of a filter material is poor is mainly solved. The filter material comprises afilter material body, wherein the filter material body comprises first fiber yarns and second fiber yarns; wherein the content of the propylene polymer forming the first cellosilk is 65 wt%-73 wt%; the content of the propylene polymer forming the second fiber yarns is 27 to 35 weight percent; the diameter size of the first fiber yarns is 2.3[mu]m-5[mu]m; the diameter size of the second fiber yarns is 3 microns to 7 microns; wherein the filter material body is provided with a gap with the pore diameter of 0.5-30 microns; the surface has a concave-convex rough structure; wherein the surface roughness Ra of the tourmaline material is 0.2-16 microns, a tourmaline material is attached to a surface groove structure or the gap of the filter material body through a dry attachment process or a wetattachment process on the filter material body, and the content of the tourmaline material on the filter material body is 0.01-3g / m<2>.

Description

Technical field [0001] The invention relates to an adsorption-enhanced filter material. Background technique [0002] Currently, in order to prevent users from inhaling pollutants in the air, respirators are usually worn on the mouth and nose of the user. The charged filter material is usually used as the filter material of the respirator. When the fluid passes through the filter material, the particles carried in the fluid will be captured by the filter material, and these charges can improve the filter material's ability to capture particles suspended in the fluid. Most of the existing respirators on the market use non-woven filter materials, which include non-woven fabrics composed of insulating polymers and non-conductive polymers. The electrically-charged insulating objects are usually called "Electret", with the development of the industry, there are now a variety of technologies for producing this product. [0003] In the early days of the charged filter material, a certai...
