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:What kind of bag is used in the food industry
Liquid filtering in the food industry is usually filtered through a nylon filter bag. The filtration of juice, drink and milk usually USES a single-layer filter bag of PP or PE, which can be used to filter the site and is relatively economical. Higher filtering requires absolute precision and 99.9% of special high-end filter bags depending on the situation.
Q:What about the filtering effect of the lubricating oil filter bag
The lubricating oil filter bag has many advantages such as simple structure, reasonable sealing, strong circulation ability and easy operation. Especially filter bag side leakage probability is small, can ensure the filtration precision accurately, and can change the filter bag quickly. The surface of the lubricating oil filter adopts mechanical sandblasting and polishing, which is uniform and easy to clean.
Q:What is the reason for the strong drop in the broken filter bag of the cement mill dust filter bag
Wear and tear. There are three reasons for the wear of cloth dust filter bags: The distribution of air turbulence is uneven. The distribution of air turbulence results in the area of the filter bag which has a high velocity of dust vapor, which causes the filter bag to wear down and the life expectancy decreases. The gas filtration rate is high. Too high a filter speed can cause a lot of dust, and the fabric fibers of the filter are easily damaged. The filter bag is too small. In the lower part of the filter bag, the abrasion is more common, the wear is more than one side, the lower part is the most serious, the upward gradually reduces, the local sewing thread will be ground broken.
Q:How can the filter bag be processed later?
Waterproof and anti-oil treatment Of needled felt filter material using fluorocarbon resin and PTFE impregnated processing oil waterproof processing, the wet dust gas dust (especially for water imbibition, deliquescence) the surface of the filter bag dust catcher, more easily to avoid and reduce the paste bag
Q:What are the features and methods of using filter bags?
The durable filtration bag is made of pure, high quality and high quality blown ultrathin fiber filter. Filter bag has excellent chemical stability and heat resistance performance, is applied to the highest in the performance of the filter material industry representatives, is all common varieties of filter material in the top performance.
Q:What is the filter bag made of foam tea?
That you go to the big supermarket will have to sell, there are two kinds, one kind is spun yarn bags, such as gauze, one is made of paper, paper bags are cheap and convenient, spun yarn is used for many times, see what you need...
Q:How is the filter material processed by the filter bag?
Finally is chemical treatment to improve the filter material, especially the dust filtering performance and the strength of glass fiber filter material, heat resistant, flame retardant, corrosion resistant performance, are of great significance.
Q:How about the filter bag of the washing machine
If you have a screen of the original filter, put a silk sock on the frame and wrap it around the outside with a strong thread
Q:Whether the washing machine filter bag is damaged or not
Does not affect the normal use, but some things on the linter and debris can't be filtered out, find a best silk stockings cut to the size of the filter bag to installed can normal use.
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,
