Abstract
The present invention provides a kind of normal temperature air filtering materials, it is characterized in that, it include: the first needle thorn layer, stichbonded fabric layer and the second needle thorn layer, the first needle thorn layer, stichbonded fabric layer and the second needle thorn layer are combined by needle point method, and the stichbonded fabric layer includes web and the loop bonding line in web that interweaves；The loop bonding line uses conductive fiber long filament or conductive yarn；Loop bonding line both ends are connected with electrode, electrode adsorption can be made more uniform as conductive absorption dust material by the loop bonding line of stichbonded fabric layer.
Description
Technical field
The present invention relates to air filting material more particularly to a kind of non-woven fabric composite filter materials.
Background technique
General electret air filting material mostly uses needle fabric, but eedle-punched non-wovens electret filtering material distribution of charges
Unevenly, cause absorption dust uneven, filter effect is bad.
Summary of the invention
(1) technical problems to be solved
In view of above-mentioned technical problem, the present invention provides one kind for solving electret air filting material mistake in the prior art
Filter a kind of normal temperature air filtering material of the bad problem of effect.
(2) technical solution
This practical new a kind of normal temperature air filtering material, comprising: the first needle pierces layer, stichbonded fabric layer and the second needle and pierces layer, described
First needle pierces layer, stichbonded fabric layer and the second needle thorn layer and combines by needle point method, and the stichbonded fabric layer includes web and interweaves in fiber
Loop bonding line in net；The loop bonding line uses conductive fiber long filament or conductive yarn；Loop bonding line both ends are connected with electricity
Pole.The electrode is anode.
The web is superfine fibre and conductive fiber composite fibre net.
The fibrous raw material of the first needle thorn layer and the second needle thorn layer is polypropene staple.
First needle thorn layer and the second needle thorn layer with a thickness of 1mm-10mm, surface density 40-00g/m2。
The stichbonded fabric layer is with a thickness of 5mm-20mm.
The stichbonded fabric layer surface density is 20-40g/m2。
(3) beneficial effect
It can be seen from the above technical proposal that a kind of normal temperature air filtering material of the present invention at least has the advantages that
One of them:
(1) electrode adsorption can be made more uniform as conductive absorption dust material by the loop bonding line of stichbonded fabric layer.
(2) dust passed through in gap in loop bonding cloth can be filtered by bilevel acupuncture filter material.
(3) web is that conductive fiber and superfine fibre composite fibre net will be so that electrode filter more in loop bonding filtering material
Add uniform also web filter effect more preferable.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of normal temperature air filtering material of the present invention.
Specific embodiment
