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:Why is the filter bag material PE a polyester, not a polyethylene
- Polyester: the general name of a polymer compound that is condensed by diglycol or polyols and dibasic acid or polyacid. Include polyester resin, polyester fiber, polyester acid glue etc. Polyester, Polyethylene terephthalate (PET) belong to the high molecular compound. Consists of terephthalic acid (PTA) and ethylene glycol (EG) through polycondensation produce polyethylene terephthalate (PET), part of the PET and ultimately generated by underwater pelletizing. Purpose: fiber grade polyester chip is used to make polyester staple and polyester filament, which is the raw material for fiber and related products of polyester fiber. Polyester film and bottle, and other purposes at the same time, widely used in packaging industry, electronic appliances, medical and health care, construction, automotive and other fields, the packaging is one of the largest non polyester fiber application market, is also the fastest growth in PET. It can be said that the polyester slice is an important intermediate product that connects the petrochemicals and the products of several industries.
- 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:Filtration efficiency of liquid filtration bag
- Different companies have different test methods and efficiency requirements of filter bag accuracy, some are defined as 80 ~ 85%, some are defined as 50 ~ 70%.
- Q:What are the features and methods of using filter bags?
- The filter bag is a key part of the process of the bag, which is usually hung vertically in the dust collector. The fabric and design of filter bag should strive for efficient filtration, easy dust stripping and durable effect. In pulse and air box type pulse precipitators, dust is attached to the outer surface of the 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:Which is the liquid filter bag?
- Rising is good.Well, it's good for Fred.I hope my answer will help you.
- 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 correct way to use a filter bag
- Fifth, replace the filter bag, blow clean with compressed air first, check for broken holes, and then replace when the holes are repaired. If the filter bag is filled with dust, rinse with water and leave after cooling. Sixth, the filter bag is blocked. When the filter bag is blocked, the resistance is raised, but the reading of the differential gauge is displayed. The filter bag jam is the main cause of the wear, perforation and loss of the filter bag.
- 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 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:What are the characteristics of a liquid filter bag?
- , good heat resistance, can be used under 280 ℃ for a long time Dust is easy to peel off The dimension stability is good, the fiberglass itself does not contract at the standard temperature
