Heat Setting

Basically all needle felts at Shandong Aobo are heat-set. 
The residual shrinkage is reduced to a minimum by means of an optimum combination of the decisive quality factors , such as temperature, dwell time and cooling phase.

The controlled process management during the cooling phase ensures that the filter bags will have excellent form stability even under most difficult conditions.

Quality-determining parameters

  • Temperature

  • Reaction time

  • Cooling time


Thermal surface treatment

The surface of any needle felt influences the structure of the filter cake, its cleanability as well as pressure drop and the emission.

-          Singed

Three different kinds of treatment are possible: 

  • smooth for adhesive and moist dust

  • medium for universal treatments

  • rough low agglomeration or fine dust

-          Calendering

Through calendering a more compact fiber structure is achieved. This allows a more surface-active separation of dust with lower emission.


Protective Impregnation

-          hydrophobic, oleophobic

This treatment makes it more difficult for moisture to penetrate into the needle felt. Thus the risk of excessive dust deposits and caking is reduced.

-          Protection against acids and hydrolysis

Special impregnation based on TEFLON®. This treatment coats the fiber surface, thus providing it with the anti-adhesive character of a PTFE finish.

An oil- and water-repelling effect is produced, and the fibers are effectively protected against acid and hydrolysis attack.

-          Active finish, hydrophobic

Special water-repellent treatment providing a high cleaning and separation efficiency.


Through the filter-active coating dust is already separated on the surface. In addition the anti-adhesive surface reduces the adhesive forces between the filter medium and dust cake.


  • Optimised cleaning

  • Increased service life

  • High separation efficiency

  • PTFE-Coating, hydrophobic and oleophobic fibers, protection against acids and hydrolysis

  • Primary finish membrane, microporous foam coating, high separation efficiency, easy dust release, hydrophobic and oleophobic

Antistatic Constructions

electrical conductive

Optimum discharge of electrostatic charges, therefore suitable for potentially explosive areas, as well as for electrostatic, strongly chargeable/charged dusts.

  • permanent      electrical conductive in accordance with DIN 54 345 part 1 by adding      stainless steel fibres into the fibre mass in accordance with DIN 54 345      part 1 or

  • alternative in      support of scrim in accordance with DIN 54 345 part 1 and part 5

Q:Please tell me where the filter bags are sold in the washer.
The filter bag is broken, the average border is good, and you can make it yourself: you can cut it up and cut it into a bag that is the size of the right size, so you can stick it to the border.
Q:How can the washing machine's filter bag be clean?
Take out the filter bag, dump the dirt, and turn the bag over and rinse.
Q:Problem with the washing machine filter bag
All this is not the problem of washing machine, washing machine filter can filter tiny fiber. The problem in the quality of a material of clothes. There is a special love of clothes stick cotton fiber, can only be washed separately, could not have other moves.
Q:Filtration efficiency of liquid filtration bag
Different companies have different test methods and efficiency requirements of filter bag accuracy, some are defined as 80 ~ 85%, some are defined as 50 ~ 70%.
Q:Does the water in the tank always relate to the washing bag
Don't wash so often, wash once in a dozen days with the urn, after a few days water is good.
Q:How to choose a liquid filter bag
1, first of all, according to the chemical name to filter the fluid, according to the chemical with taboo to find available filter material, commonly used in PE, PP, PTFE, NMO, again according to its operating temperature, operating pressure, ph, operating conditions (such as whether to need to tolerate steam, hot water or chemical sterilization, etc.), assessed and eliminate shall not apply to the filter material. Use is also an important consideration, such as pharmaceutical, food or cosmetic ingredients that must be approved by the FDA; Ultra-pure water should be chosen for pure and not contain the filter material that will affect the impedance. Filter gases should be selected for hydrophobic materials and whether "health grade filtering" design is required. The main foreign Filter bags are GAF, FSI, 3M, CUNO, U.S. Filter, LOEFFLER, PARK, Vablue Filter bag etc
Q:The filter bag is very thick and it's hard to wash everybody how to do it
When you cut through a knife, you must first wipe the surface of the oil with peanut oil so that it won't stick to the blade. By the way, to teach you how to reduce the mucus in the jackfruit: amount of mucus in the jackfruit is and is inversely proportional to the familiar with degrees, that is, the more the more immature mucous, usually just picked from the tree of jackfruit is not mature enough, must put a few days time to eat, to reduce mucus and shorten the time of the park, you can take a little insensitive, section size and jackfruit hanging in a tree when the hanging rattan almost went,
Q:Which is the liquid filter bag?
Liquid filter bag quality is good, pay attention to is to see the efficiency of the filter cloth, pore size distribution, density, porosity, fracture strength, thickness, weight, etc. A series of technical indicators.
Q:What materials are commonly used in liquid filtration bags?
1, good heat resistance, can be used under 280 ℃ for a long time Dust is easy to peel off The dimension stability is good, the fiberglass itself does not contract at the standard temperature
Q:How can the filter bag be processed later?
Dust filter bags can be processed according to specific requirements. Yiqing ash treatment Adopts the patent technology production Yi Qing ash density and breathable, needled felt filter material itself has a good soot cleaning performance, and can work long hours under high filtration velocity. Antistatic processing In certain concentrations, some dust occurs when a spark burns or is generated by friction. Therefore, it is suitable for inflammable and explosive dust to be used in the needle felt filter. Antistatic filter is used to describe the mixing of the filter fibers The conductive fibre (including the dual conductive fibre, graphite-conductive fibre and stainless steel conductive fibre) enables the whole filter to conduct electrical conductivity
