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 is the line on the top of the filter bag?
The filter bags are divided into three types: the ribbon filter, stationary filter and twill filter.
Q:How to remove the filter bag of semi-automatic washing machine?
Filter the plastic card button down, and gently pull out!I hope my answer will help you.
Q:Please tell me where the filter bags are sold in the washer.
This kind of thing is sold after sale.I hope my answer will help you.
Q:How do you use a filter bag?
Third, the cloth should not hang too loosely or too tightly, too easily to accumulate dust, too close to pull out. Fourth, new process old filter bag should not be mixed, avoid damage time different effect equipment normal work
Q:How do you clean a filter bag with oil stains?
Clear the dust filter bag with oil: using high frequency vibration, will enter the dust filter bag inside the wall of the larger dust particles removed, will not affect fiber entanglement of fastness, keep the filter bag is good, easy tear of dirt. Chemical experiment treatment: extract the bag samples, using the professional instrument laboratory detection filter filter bag oil composition, to adapt to washing raw materials, the maximum cleaning filter bag and without causing any damage to the filter bag.
Q:What is the advantage of the oil filter bag?
The spinning shield can almost eliminate fiber transfer Intercept various soft and hard particle impurities
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:What are the characteristics of a liquid filter bag?
Chemical etch is good, acid and alkali resistance. The filtration efficiency is high, can reach more than 99.5%
Q:Is there a filter bag for the washer?
A cylinder washer is not a filter bag. And there's no drain valve, but he has a pump. So where did the dirt go? You can look at the structure of the drainage pump first.In fact, he is a vane pump, so the dirt not sensitive, general MAO flocculant, can be directly into the sewer, there is no need to filter bag, larger smudgy, can open the cover to remove. The experience I've been using for a decade or so is that there is no such thing at all
Q:What do you do when the washing machine is connected to a filter bag
Remove the filter bags, remove the wheels and use the thick wire channel
