Background technique
Currently, country requires dust emission concentration generated in industrial production the ultrapurification for gradually tending to 10mg/Nm3
Standard, under this requirement, while in view of industrial continuity, domestic each industry damaged to reduce filter bag mechanical friction
Dedusting filtering bag used in not requiring nothing more than will have the filter effect of long-acting high purification, there is good external force resistance polishing machine again.
However, traditional PTFE (Poly tetra fluoroethylene, polytetrafluoroethylene (PTFE)) membrane bag filter surface film
Wearability and resistance to mechanical power are poor, cannot persistently keep its integrality with the continuity of work, will cause later period dust emission
The exceeded problem of concentration index；The dust emission that existing fine count fiber Nomex is difficult to realize again lower than 10mg/Nm3 simultaneously is wanted
It asks.
Therefore, a kind of dust emission standard being not only able to achieve lower than 10mg/Nm3 how is developed, but also is had excellent wear-resistant
Damage the nano level superfine denier fiber needled felt of performance, it appears particularly important.
Utility model content
For this purpose, technical problem to be solved by the utility model is to provide a kind of PA/PET sea-island fibre hydroentangled layer is compound
Nomex to reach the dust emission effect for being lower than 10mg/Nm3, and has excellent antiwear performance.
Then, the utility model provides a kind of PA/PET sea-island fibre hydroentangled layer compound spiked felt, from surface down according to
It is secondary are as follows: PA/PET sea-island fibre hydroentangled layer, fine fiber layer, polyester filament base cloth layer and conventional fibre layer, the island PA/PET are fine
Tieing up hydroentangled layer is using the independent 100%PA/PET sea-island fibre into the net of water jet process, fine fiber layer, polyester filament base cloth layer
With conventional fibre layer by needling process mutually embrace entanglement close be fixed to one another, PA/PET sea-island fibre hydroentangled layer again by needling process with
Fine fiber layer, polyester filament base cloth layer and conventional fibre layer are mutually embraced entanglement conjunction and are fixed to one another.
Wherein, the PA/PET sea-island fibre specification in the PA/PET sea-island fibre hydroentangled layer is 3.0D × 51mm, fibrillation
Nanoscale PA fibre number afterwards is 0.08D.
The PA/PET sea-island fibre hydroentangled layer unit area grammes per square metre is 100g/m2
The fine fiber layer includes 1.5dtex fine count fiber and 2.0dtex conventional fibre, 1.5dtex fine count fiber with
2.0dtex conventional fibre mixed proportion is 3:7, and fine fiber layer unit area grammes per square metre is 135g/m2.
The conventional fibre layer includes 1.5dtex fine count fiber and 2.0dtex conventional fibre, 1.5dtex fine count fiber with
2.0dtex conventional fibre mixed proportion is 5:5, and conventional fibre layer unit area grammes per square metre is 235g/m2.
The polyester filament base cloth layer unit area grammes per square metre is 80g/m2.
The PA/PET sea-island fibre hydroentangled layer is fixed on fine fiber layer upper surface by 42# thin footpath pricker needle thorn.
PA/PET sea-island fibre hydroentangled layer compound spiked felt described in the utility model uses water jet process by surface setting
It is formed by PA/PET sea-island fibre layer, Nomex matter even density can be made compact-sized, Nomex surface layer can be effectively improved
Abrasion resistance energy, the long-term structural stability for keeping surface fiber layer, while the nanoscale PA fiber in surface layer can form mostly empty
Gap aperture gauge structure can effectively hinder small particle dust, reach the dust emission standard lower than 10mg/Nm3, and have excellent anti-
Polishing machine.
Detailed description of the invention
Fig. 1 is PA/PET sea-island fibre hydroentangled layer compound spiked felt structural schematic diagram described in the utility model embodiment；
Specific embodiment
In the following, the utility model is described in detail in conjunction with attached drawing.
