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 a good filter bag?
- The longitudinal suture of the filter bag must be flat, firm and must not exceed three. The stitches of a cloth bag dust collector shall not be less than two. Also, the loop stitching of the filter bag is stronger than the two.
- Q: How to remove the washer filter bag
- It's easier to have a plastic filter bag on the side of the cylinder, and you press down the card with a bit of force, and you can get it out.
- 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: How about all the filters in the washing machine
- It's better than buying a new filter bag to put the stockings on a plastic stent that's broken
- Q: What is the filter bag for the washing machine?
- Some clothes make it easy to get a ball, which is to filter the little ball
- Q: How is the filter bag chosen?
- Ordinary on the premise of the flue gas temperature, dust removal filter bag can only demand resistance to below 150 ℃, the temperature of these places, polyester, polypropylene, acrylic, nylon and other chemical fiber can be competent at all.
- Q: What materials are commonly used in liquid filtration bags?
- Chemical etch is good, acid and alkali resistance. The filtration efficiency is high, can reach more than 99.5% Expanding filter cloth (bag), improving filter wind speed and filtration efficiency, reducing the volume of dust removal equipment
- Q: How to unload the washing machine's filter bag?
- The fixed device of a filter bag may be three clasps, and the hard drag is not coming, and you try to use a zig-zag screwdriver to pry into the lock.
- Q: How to check the filter bag and the dust collector bag when the dust collector is installed?
- Installation of bag filter bag quality inspection is also more important, with the bag cage check: because of the bag filter to board, cooperation between the bag and the bag cage requirements is very high, so when installing the bag cage must strictly control the space between the cage with a bag, bag to fit clearance beyond the technical requirements of replacement at once. Finally after installation of the re-inspection, the bag cage after installation, for all the bag cage installation, check one by one, the quality of the installation, review the top of the bag cage with the bag mouth and bag cage, stable performance.
- Q: Is it better to dust the air with a filter or a filter?
- The filter is characterized by high filtration precision, and different filter cores (activated carbon, ultrafiltration membrane, etc.) have different functions.
