what is nonwoven filter fabric?
The name of non woven filter fabric is called polyester fiber, commonly known as non woven fabric. Air filter material has technical characteristics such as wide use, technical maturity, and good stability. It is a primary effect plate air filter, a medium effect plate air filter, and a bag air filter. Non woven filter fabric is one of typical filter material. The manufacturing process is compounded by multiple processes such as melt - blown, needle punch, spunlace, spunbond and other processes. Compared with other air filter material of the same level, non-woven filter material have the advantages of stable quality, larger dust holding capacity, strong moisture resistance, long service life, economical durability and so on. Non woven fabric is also the earliest application of filter material. The technology is mature and the production cost is low. In recent years, due to the continuous progress of technology, the emergence of composite fabric can improve the image of non woven fabrics in terms of cheap and low - grade. At the same time, composite non fabric air filter media can also be used for filtering in places where air cleanliness is relatively high.
Needle punched filter cloth, a non woven filter material formed by carding fibers into a net and then reinforced by a needle punching machine. After needle punching and reinforcement, many tiny holes will be left on the cloth surface, which has good air permeability and pore arrangement. It has the advantages of uniformity, high tensile strength, and easy folding.
Spunbond filter cloth is a non woven filter material formed by polymer chips, extruded and melted, spun into a fiber web and then reinforced by hot pressing. The only disadvantage is that the uniformity of the web is poor, and the thickness is uneven to appear after the cloth formed.
Spunlace filter cloth, a non woven filter material reinforced by high - pressure spunlace on the fiber mesh, has the advantages of fine and smooth cloth surface, high strength, small pore size, good air permeability, resistance to lint, and cleanness. The environment and raw material requirements will be higher, so the production cost is higher than other non-woven filter materials.
Melt blown filter cloth is a kind of non woven filter material composed of superfine fibers with three - dimensional random distribution. The advantages are similar to the above types of non woven filter materials, but there are also disadvantages such as low tensile strength and wear resistance. The aspect is also not ideal.
