Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, before not making the creative labor property
It puts, is also possible to obtain other drawings based on these drawings.
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the schematic diagram of internal structure of the utility model.
Description of symbols: nonwoven fabric layer 1, adhesive-bonded fabric decorative pattern 2, layer of support material 3, oval decorative pattern 4.
Specific embodiment
Referring to shown in Fig. 1-Fig. 2, present embodiment the technical solution adopted is that: discharge collodion silk to support at intervals
The surface of material, it is then compound with melt-blown nonwoven fabric；Due to the special tectonic of melt-blown nonwoven fabric, collodion silk and backing material are connect
When touching, can sufficiently it bond.While not influencing peel strength, can reduce and spit collodion silk amount, generally, collodion silk amount 1.0~
2.0 grams every square, the art of this patent can be reduced to 0.5~1.0 gram every square, at the same peel strength 60g/2.5cm with
On.
The depth up and down of oval decorative pattern is in 0.5~2.0mm, and long axis and minor axis length ratio are 2.0~10.0.Depth is up and down
The depth or male portion of concave portions and plane and the depth of horizontal plane.The condition of concavo-convex portion can pass through suction air volume
To carry out condition.Example: being tested using the face Testo 405V1 anemobiagraph, and for wind speed in 4.0m/s, depth is close face to face
0.5mm, when reaching 8.0m/s, depth is close to 2.0mm.It is of course also possible to by suction air volume, lace curtaining speed, hot blasting amount,
The combinations such as spinneret height adjustment, reaches the pattern depth of needs.When depth is lower than 0.5mm, foundation attaching space can be very
It is small, or even under the influence of high air quantity, without effect.Meanwhile when being higher than 2.0mm, since fibre deformation is excessive in adhesive-bonded fabric,
Interfibrous gap perhaps hole can become larger thus when dust or PM2.5 particulate matter easily propagate through adhesive-bonded fabric, be not achieved
Filter effect.For, the length ratio of long axis and short axle, be in order to backing material compound tense, length direction sufficiently connects with collodion silk
Touching bonding.More than 10.0, it can make to contact excessively with collodion silk, influence air permeability and namely increase resistance.Lower than 2.0 and collodion silk is non-
The effect of the contact hole with backing material is not achieved in contact portion.

Less than 15 degree.The long axis of oval decorative pattern along a first direction when, be easy and collodion silk contact bonding be secured.Meanwhile general and support
After Material cladding, needing pleating to be processed into filter core could be used.Pleating direction is first direction, and same direction is also easy to
Pleating molding.For angle, it is preferable to recommend that there are certain angles, can suitably reduce the contact surface with collodion silk, reduce resistance.But
When being more than 15 degree, necessary contact surface, that is, peel strength can be reduced, and influence rear road pleating processing and normal use.
Preferably 1.0~the 2.0mm of depth up and down of oval decorative pattern, long axis and minor axis length ratio are 3.0~4.0.Current mistake
Filter field is developed to high air quantity direction, and when Gao Fengliang, the requirement to upper and lower depth is got higher, this patent preferably 1.0~2.0mm
When, High dust holding, the effect of low-resistance are more preferable.Meanwhile long axis and minor axis length ratio can make High dust holding, low-resistance preferably 3.0~4.0
Effect it is more preferable.
