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.

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.
Coatings
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.
Advantages
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

Company Information
- Q:What is the fabric of a filter bag?
- Plain weave: this is the simplest form of weaving, every root warp and weft and alternate, but plain weave has disadvantages of difficult to clear ash and easy to jam, as a result, the weaving organization has rarely used for dust removal filter material;
- Q:Why is the filter bag material PE a polyester, not a polyethylene
- It is divided into high density polyethylene, medium density polyethylene and low density polyethylene according to the density. Polyethylene is a high polymer chain that is connected by a repeat - CH2 - unit connection through the addition and polymerization of ethylene (CH2 = CH2). Purpose: polyethylene insoluble in water, water is very small, is about some chemical solvents, such as toluene, acetic acid, etc., and only showing modest dissolved when temperature above 70 ℃. But polyethylene particles shape, can be between 15 ℃ and 40 ℃ melting or solidification, along with the change of temperature at higher temperatures melt, absorbing heat; When the temperature drops, it solidifies, releasing heat. Because it absorbs little water, it is not wet, it has insulation, so it is a good building material.
- Q:What is a good filter bag?
- For lower material length to be less than 10mm, the surrounding is quilted. When sewing cloth bags, the bag is not less than 15 needles every 10 centimetres, not less than 12 stitches per 10cm. Finally, in the process of sewing, the filter bag can not be damaged or leak.the diameter is greater than 20 centimeters and the length is greater than 5 meters.
- Q:Can liquid filtration bags be cleaned and reused
- According to the mechanism of liquid filtration process, surface filtration and deep filtration are classified.
- Q:Choose what aspects to consider when choosing a filter bag
- Dust and dust are collected in the outer surface of the filter, while the clean gas is filtered through the filter. The inside of the filter bag is used to support the filter bag to prevent the bag from collapsing, and it helps to clear and redistribute the dust cake.
- Q:In what aspects is it convenient to choose the filter bag?
- The dust bag is chosen according to the special properties of dust. Dust is moist and sticky. If the dust is wet and sticky, choose a filter bag that is waterproof and coated. The flammability and charge of dust. Some dust can be flammable when it is necessary to choose the fire-retardant cloth bag. Antistatic filter bags are specially used for the charge of electrically charged dust.
- Q:The filter bag is very thick and it's hard to wash everybody how to do it
- The original poster hello! Saline and alcohol don't solve the problem. The most reasonable way to eat jackfruit for years is to use peanut oil. If the mucus of jackfruit is in your hand, you will be able to scrub it with a small amount of peanut oil
- Q:How do you pack the filter bags in the washing machine
- Can observe filter plate have an arrow above, according to the location of arrows, have hands press card, can win filter, fasten can directly when installation;
- 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 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.
