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:Whether the washing machine filter bag is damaged or not
It doesn't affect the filter bag that can only filter the washing in a wash bucket
Q:What is the cleaning method of the filter bag
A lot of businesses don't know how to clean the filtered bags, and I'll show you how to clean the filter bag. Consumers only need to see the dust on the filter bag is able to know how its dust removal effect, it's really useful in our lives is very big, can not only filter the air we breathe, make our life better, but also can The removal of some other impurities is relevant to the quality of our lives. It is also important to note that the filter bags also need to be cleaned properly, but the cleaning is very simple and will only be released when washing Into a bit of cleaning fluid, bath, ten minutes, can clean up all the filter bag impurities, attention is best when washing with warm water to wash, because it can wash clean,
Q:Please tell me where the filter bags are sold in the washer.
The filter is sold after sale. But quite expensive.I hope my answer will help you.
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
Q:What about the filtering effect of the lubricating oil filter bag
With the development of the industry, the lubricating oil filter bag is widely used in various fields of industrial occasions, lubricating oil filter bag is one of the most critical steps in the process of the filter.
Q:What is the filter bag made of foam tea?
Hello, this kind of tea bag is used for the high grade filter paper with the combination of log and fiber, this paper is environmentally friendly and easy to handle and easy to use
Q:Choose what aspects to consider when choosing a filter bag
Class at low temperature, suitable for raw meal grinding, cement mill, such as top bottom library local point of dust bag filter is used, and used in under the condition of high moisture content still need to adopt oil-repellent waterproof treatment on the surface to surface treatment. Often, high temperature, is suitable for the shaft kiln cement and rotary kiln preheater, cooling machine, dryer, etc. The high temperature of waste gas treatment of bag filter, and is used in high temperature, high humidity content under the condition of still need to use oil-repellent waterproof treatment on the surface to surface treatment.
Q:How to choose a liquid filter bag
Filter bag precision options: This is the most troubling question. For example, to remove visible particles, use a 20 or 25 micron filter bag. To remove the cloud from the liquid, use a 1 or 5 micron filter bag. To filter out the smallest bacteria, you need a 0.2 micron filter bag. The problem is that there are two types of filter units: absolute accuracy/nominal accuracy.
Q:How to unload the washing machine's filter bag?
Press the card in the filter bag and come down. Don't drag ah. And left and right, are there any buttons nearby
Q:Is it better to dust the air with a filter or a filter?
Each has its own characteristics and USES to choose according to the use case. The filter bag is characterized by processing power, which has little effect on the flow rate of gas and long life.
