Aramid needle-punched non-woven fabric is a non-woven fabric made of aramid fiber through a needle-punching process.Aramid is a synthetic fiber with excellent heat resistance, chemical corrosion resistance and high strength. It is often used in protective clothing, filter materials and other fields.The needle punching process is a process in which fiber layers are stacked together and then multiple needles on a needle punching machine are used to pierce the fiber layers so that they are intertwined to form a non-woven fabric.This process can enhance the bonding force and strength between fibers, making the non-woven fabric tougher and more durable.Aramid needle-punched non-woven fabrics are often used in high-temperature filtration, thermal insulation protection and other fields.
