Product Description:
According to the types of synthetic monomers, acrylic fibers could be divided in to homopolymers and copolymers. The homopolymer acrylic has the structure of polymerization of a single monomer, with the spatial of spiral rod structure, and quasicrystalline in crystalline structure. There is a -cn group on the side of the molecule, and the dipole or hydrogen bonding between the molecules makes it difficult to slip,and the homopolymer is inflexibility.
The copolymer a crylicis combined with the second and third monomers embedded in the polyacrylonitrile macromolecule, which destroys the helical structure, makes it dislocation,bending, twisting and others, which affects the continuity of the crystal along the axis of the macromolecule. This makes the structure becomes soft, and the fiber is strong and stretchable.
However, the maximum working temperature of homopolymer is 130°C, and the instantaneous working temperature < 140°C. The maximum temperature of copolymer is 120°C, and it is not resistant to hydrolysis, that’s why our Acrylic filter fabric are made out by 100% homopolymer acrylic fibers.

Advantage of Acrylic Needle Felt Filter Fabrics:
- Good resistance to organic solvents,oxidants, inorganic and organic acids,
- Working PH value 3-11
- Good hydrolysis resistance
- Excellent sun light resistance
Disadvantage of Acrylic Filter Fabrics:
Acrylic fiber is notable to self-extinguish after burning. Usually the dust bag works in a dry and ventilated environment, when it encounters sparks or static sparks, it’s very easy to burn.
In response to this fatal shortcoming, we use PTFE dipping or membrane on the acrylic needle felt for flame retardant treatment, the PTFE membrane make the fabric surface has small and uniform micropores (0.10-2.0μm), which can capture all the dust larger than the micropores. So our Acrylic nonwoven needle felt filter would collect the PM10 & PM 2.5 at rate 99.99%.
