(1Polyeater Needle Felt
Polyester needle-punched filter cloth is a fine fiber filter material produced by non-woven needle-punching technology, with fibers arranged in an interlaced manner and uniform pore distribution. This filter cloth is made from polyester short fibers and twisted yarns. After undergoing post-treatment such as hot rolling, scouring, or coating, its surface becomes smooth and flat, making it less prone to being clogged by dust. This filter material has a large porosity, good air permeability, and is widely used in various fields. It has strong chemical stability and is an ideal filtering material for normal temperature working conditions and gas-solid separation applications.

During the operation of bag-type dust collectors, for dust in the air that contains a large amount of moisture and oil, as well as hygroscopic and easily deliqueshable dust, a water film may form on the surface of the dust, thereby increasing adhesion. Although this is helpful for dust capture, it will make dust cleaning difficult, especially when in a high-humidity state, condensation may occur due to the cooling effect of the external gas. This not only causes the collected dust to form scale on the surface of the filter material and thus clog it, but also increases the operating resistance of the dust removal equipment, directly affecting the normal operation of the dust removal equipment. Water-repellent and oil-proof needled felt can effectively prevent water and various oil contaminants from adhering and penetrating. Compared with ordinary filter materials, it not only has oil-proof and oil-proof properties, but also has anti-caking and easy-to-peel properties for dust.

,,Product Description:
When the concentration of industrial dust reaches a certain level (i.e., the explosion limit), if it encounters factors such as static discharge sparks or boundary ignition, it is very likely to cause explosions and fires. For example, coal dust, chemical dust, explosive dust, etc. There is a possibility of explosion in case of static discharge. In the field of bag-type dust removal, if these dusts need to be collected by bags, the bags themselves are required to have anti-static functions. In addition to the production process of ordinary needled felt, the production of anti-static filter materials also requires the incorporation of conductive fiber yarns into the base fabric warp yarns for the production of needled felt.

In the field of bag filter, for industries with relatively high flue gas temperatures, chemical fibers capable of withstanding high temperatures are needed to manufacture filter materials, which can fully meet the high-temperature working conditions of 150-220ºC. Inmetas fibers belong to aromatic polyamide fibers, which have excellent heat resistance, wear resistance and folding resistance. Their folding resistance is irreplaceable by glass fibers. It is applicable to industries such as asphalt mixing, steel, cement, and non-ferrous metal smelting.
Product Description:
FMS needled felt is a new type of high-temperature and high-efficiency composite fiber material with a reasonable structure and excellent performance. It not only has the advantages of glass fiber woven filter material such as high temperature resistance, corrosion resistance, dimensional stability and high strength, but also is made from 100% alkali-free glass fiber as raw material, using high-count glass fiber filaments and needling them into fibers. It has good heat resistance, flame retardancy and anti-corrosion effects. It has low gas resistance, a dust removal efficiency higher than that of woven filter materials, and a filtration speed about twice as high as that of woven filter materials. It is currently the preferred product for purifying blast furnace gas and flue gas filtration in the steel, smelting and other industries.

Product Description:
P84 needled felt is made from P84 fibers (i.e. polyimide fibers) produced by LENZING Company of Austria through three-dimensional treatment
It is needle-punched and has excellent high-temperature resistance, with a temperature resistance of up to 260ºC. Moreover, the cross-section of P84 fibers is irregular leaf-shaped, which can significantly enhance the filtration effect. The fibers themselves also have certain resistance to hydrolysis and oxidation. This product has good temperature resistance and filtration effect, and is widely used in complex working conditions such as the kiln head and kiln tail of cement plants, waste incineration, and coal-fired boilers.
