As we all know, the air is filled with countless tiny particles that pose potential threats to human health. To effectively defend against these particles, filter fabric has become an indispensable tool for us. This article will provide an in-depth analysis of the differences between non-woven filter fabric and synthetic fibre filter fabric.
Synthetic fibre filter fabric, as an emerging filtering material, is gradually replacing non-woven fabric and fiberglass, covering a full range of coarse, medium, and high-efficiency filtering products. It primarily uses polyester fiber (PET) as the main raw material and has numerous advantages, such as low resistance, light weight, large capacity, environmental friendliness (can be incinerated), and moderate price. Polyester fiber has excellent wrinkle resistance, elasticity, and dimensional stability, and can resist weak acids and alkalis, as well as sunlight and friction, giving it a broad application prospect in the filtering field.
Non-woven filter fabric, technically named polyester fiber, is also commonly known as non-woven fabric. This type of filter fabric is renowned for its mature technology and good stability, making it the preferred filter material for primary and medium-efficiency plate and bag filters. Meticulously crafted through multiple processes such as melt-blowing, needling, hydroentangling, and spunbonding, non-woven filter fabric demonstrates stable quality, large dust-holding capacity, strong moisture resistance, long service life, and economical durability. In recent years, continuous technological advancements have led to the emergence of composite non-woven fabric, which has improved its cheap and low-grade image, achieving near-high-efficiency filtration levels. Moreover, composite non-woven filter materials are suitable for places with high air cleanliness requirements.
In summary, non-woven filter fabric and synthetic fibre filter fabric each have their strengths. Non-woven fabric, with its mature technology and stable performance, is widely applied in the filtering field; while synthetic fibre filter fabric shows great development potential with its emerging technology and excellent performance. The choice of which filter fabric to use depends on the specific environment and needs. However, regardless of the choice, they are both important tools for us to maintain clean air and ensure health.
