Non-woven material, the non-woven material be on the material substrate of dry-laying laying wet laid material surface layer, through water
Thorn consolidation forms composite fiber web.
The wet laid material surface layer is superbhort fiber surface layer.
The superbhort fiber of the superbhort fiber surface layer is from surpassing that the shredding again of non-woven waste material and leftover pieces is obtained
Chopped fiber.
The specific production technology of the application：Dried polymer chips leads through screw extruder melt spinning by air-flow
Stretch lapping spun-bonded continuous yarn base fabric of the formation with very high-tenacity and be laid on bottom as enhancing base materials.Waste and old filter bag enters opener
Again chopping shredding turns into the superbhort fiber of 3-15mm, and superbhort fiber enters wetlaid apparatus and forms superbhort fiber surface layer, leads to
Lapping machine laying is crossed on spun-bonded continuous yarn base fabric base material, upper and lower two-layer composite fiber web is formed, spun lacing consolidation is eventually passed,
Post-processed.Wherein, spun-bonded continuous yarn base fabric strength is good, can be used as main strength base material；Superbhort fiber surface layer has extremely excellent
Be combined with each other for both advantages by filter effect, the application.The flexible reinforcement process of spun lacing, does not damage fiber so that the application
Non-woven material tangle more to fasten.
Superior effect of the invention is：
1）Shredding is waste and old again and discarded damaged filter bag and filtrate for the application, is allowed to become superbhort fiber, by wet method into
Net by the fleece of dry-laying as base material, then reinforces entanglement and forms composite fibre as surface layer by the flexible of spun lacing
The non-woven material of net, strainability is high；
2）The application non-woven material porosity is high, intensity is big, surfacing, filterability are good, it is possible to achieve multi-level ladder
Spend filter；
3）Cost of material used herein is low, and source is wide, can solve the problem that the problem that recycles of waste and old filtrate, becomes useless
It is treasured, recycles waste and old and discarded damaged filter bag and filtrate, has saved production cost；
4）The application protects natural environment, solves secondary pollution, realizes the strategy of resource environment sustainable development.

Specific embodiment
Embodiments of the invention are described in detail below in conjunction with accompanying drawing, but the present invention can be defined by the claims
Multitude of different ways with covering is implemented.
Embodiments of the invention are described in detail with reference to Fig. 1.
Fig. 1 shows the figure of the embodiment of the present invention.As shown in figure 1, the invention provides a kind of two kinds of dry and wet into net mode
The non-woven material of spun lacing consolidation is combined, the non-woven material is to lay wet-laying on the material substrate of dry-laying
Material surface layer, consolidates to form composite fiber web through spun lacing.
The wet laid material surface layer is superbhort fiber surface layer 1.
The superbhort fiber of the superbhort fiber surface layer 1 is from surpassing that the shredding again of non-woven waste material and leftover pieces is obtained
Chopped fiber.
The specific production technology of the application：Dried polymer chips 3 is through screw extruder melt spinning by air-flow
Drawing-off lapping forms the spun-bonded continuous yarn base fabric 2 with very high-tenacity and is laid on bottom as enhancing base materials.Waste and old filter bag enters to be opened
Loose machine shreds superbhort fiber of the shredding as 3-15mm again, and superbhort fiber enters wetlaid apparatus and forms superbhort fiber surface layer
1, by lapping machine laying on the base material of spun-bonded continuous yarn base fabric 2, upper and lower two-layer composite fiber web is formed, eventually pass spun lacing consolidation
Shaping, is post-processed.Wherein, the strength of spun-bonded continuous yarn base fabric 2 is good, can be used as main strength base material；Superbhort fiber surface layer 1 has
Be combined with each other for both advantages by extremely excellent filter effect, the application.The flexible reinforcement process of spun lacing, does not damage fiber so that
The non-woven material of the application tangles more to fasten.
The wetlaid apparatus include inclined wire formula wetlaid apparatus and cylinder wetlaid apparatus.
