Product Parameters
(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.

,..Product Description:
Acrylic needle-punched felt is made by non-woven needle-punching technology, which utilizes the interlaced arrangement of strong acrylic fibers with uniform pore distribution. The surface of the fine fiber filter material is treated with hot rolling, singeing, etc., making it smooth and flat, and not easily clogged by dust. This filter material has large pores. It has good air permeability and strong chemical stability. It can not only filter gases at normal temperature but also has good hydrolysis resistance. This product is applicable to the field of flue gas filtration with high water content such as cement slag particles.

,.PPS needled felt is made by needling 100% PPS fibers. PPS fibers, with their excellent acid and alkali resistance, oxidation resistance, wear resistance and folding resistance, enable the composite felt to withstand a normal temperature of up to 160ºC and a short-term temperature of up to 190ºC. It is suitable for fields with high sulfur content such as flue gas filtration in thermal power and coal-fired boilers

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.
