Description
Technical field
This utility model belongs to composite filter material technical field, refers in particular to a kind of composite filtering cloth.
Background technology
At present, the filter cloth that the filter cloth of existing industry is typically woven by long filament gold and staple, or by monofilament
Filter cloth with long filament braiding.Dust granules of the existing filter cloth for diameter below 5 microns are difficult to filter out, and
Some dust have viscosity, and common filter cloth is once attached with dust, if not clearing up, affect filter effect, even result in
Filter cloth fails.
Content of the invention
The purpose of this utility model is to provide a kind of simple structure and stable, the composite filtering cloth of good filtration effect.
The purpose of this utility model is realized in：
A kind of composite filtering cloth, including filter cloth body, the filter cloth body is disposed with politef from top to bottom
What microporous film layer, high-denier-fibre cross lapping were made meets knoisphere, the base cloth layer that the braiding of PET long filaments is made and high-denier-fibre
The supporting layer that cross lapping is made, described meeting link reinforcing, institute by acupuncture complex method between knoisphere, base cloth layer and supporting layer
State polytetrafluoroethylmicroporous microporous membrane layer stick in described meet on knoisphere, polytetrafluoroethylmicroporous microporous membrane layer is non-sticking lining.
For unflocked surface, adhesion on unflocked surface has polytetrafluoroethylmicroporous microporous membrane layer to the knoisphere upper surface of meeting.
Spacing≤2mm between PET long filaments and PET long filaments in the base cloth layer that the PET long filaments braiding is made.
The thickness of the polytetrafluoroethylmicroporous microporous membrane layer be H4, and, 0.01mm≤H4≤0.1mm.
What the high-denier-fibre cross lapping was made meets knoisphere thickness for H3, and, 0.5mm≤H3≤2.5mm.
The base cloth layer thickness that PET long filaments braiding is made is H2, and, 0.1mm≤H2≤0.5mm.
The supporting layer thickness that high-denier-fibre cross lapping is made be H1, and, 0.5mm≤H3≤2.5mm.
This utility model is prominent and beneficial compared to existing technology to be had the technical effect that：
1st, of the present utility model for MULTILAYER COMPOSITE filter cloth, dust of the diameter less than less than 5 microns can not only be filtered
Grain, and strengthen the bulk strength of filter cloth such that it is able to life-time service in the environment of high intensity, long service life, cross and filter
Dirt effect is good.
2nd, the filter cloth body of the present utility model is disposed with polytetrafluoroethylmicroporous microporous membrane layer, thick fibre from top to bottom
What degree fiber crossovers lapping was made meets what knoisphere, the base cloth layer that the braiding of PET long filaments is made and high-denier-fibre cross lapping were made
Supporting layer, meets the advantages of knoisphere is identical with supporting layer material, and which has intensity height, heat-resisting and good aqueouss；Base cloth layer has good
Good mechanical property, folding resistance is good, and high temperature resistant and low temperature；Polytetrafluoroethylmicroporous microporous membrane layer be non-sticking lining, Ke Yiyou
Effect ground solves the problems, such as that filter cloth is attached with dust, and the micropore of non-sticking lining is used in filter cloth for permeable or ventilative,
So that its filter effect is more preferably, and long service life.
3rd, for unflocked surface, adhesion on unflocked surface has politef micropore thin to the knoisphere upper surface of meeting of the present utility model
Film layer, unflocked surface cause both adhesion effects more preferably, simple structure and stable.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
This utility model is further described with specific embodiment below in conjunction with the accompanying drawings, as shown in Figure 1：
A kind of composite filtering cloth, including filter cloth body, the filter cloth body is disposed with politef from top to bottom
What microporous film layer 4, high-denier-fibre cross lapping were made meets knoisphere 3, the base cloth layer 2 that the braiding of PET long filaments is made and heavy denier
The supporting layer 1 that fiber crossovers lapping is made, it is identical with 1 material of supporting layer to meet knoisphere 3, and which has intensity high, and heat-resisting and aqueouss are good
The advantages of good；Base cloth layer 2 has good mechanical property, and folding resistance is good, and high temperature resistant and low temperature；Politef micropore is thin
Film layer 4 is non-sticking lining, can efficiently solve the problem that filter cloth is attached with dust, the micropore of non-sticking lining be used for permeable or
Ventilative, be used in filter cloth so that its filter effect more preferably, and long service life；Described meet knoisphere 3, base cloth layer 2 and
Reinforcing is linked by acupuncture complex method between support layer 1, overall structure is stable, 4 adhesion of polytetrafluoroethylmicroporous microporous membrane layer
Meet on knoisphere 3 described.
By singing processs, therefore upper surface is unflocked surface to 3 upper surface of knoisphere of meeting, and adhesion on unflocked surface has polytetrafluoro
Ethylene microporous film layer 4, unflocked surface cause both adhesion effects more preferably, simple structure.
Spacing≤2mm between PET long filaments and PET long filaments in the base cloth layer 2 that the PET long filaments braiding is made, the design
So that structure is more stable, and dust granules of the diameter less than less than 5 microns can be filtered.
The thickness of the polytetrafluoroethylmicroporous microporous membrane layer 4 be H4, and, 0.01mm≤H4≤0.1mm.
What the high-denier-fibre cross lapping was made meets 3 thickness of knoisphere for H3, and, 0.5mm≤H3≤2.5mm.
