Synthetic fiber felt boasts excellent air permeability. After heat treatment, its surface becomes smooth and flat, making it resistant to deformation and easy to apply plaster. Polyester needle-punched filter media treated with water- and oil-repellent coatings exhibit water-repellent properties, making them ideal for applications involving flue gases with high moisture content or containing small amounts of oil contamination. This prevents bag sticking and significantly extends the service life of the filter. Synthetic fiber felt filter media coated on the surface with a microporous polytetrafluoroethylene (PTFE) film features a smooth surface, hydrophobicity, breathability, and ease of dust removal. It offers high filtration efficiency, low operating resistance, and low energy consumption.
Chemical fiber felt is a fine-fiber fabric produced by nonwoven needle-punching technology, featuring interlaced fibers with uniformly distributed pores. The surface of the needle-punched felt, made from polyester staple fibers and polyester yarns, undergoes post-processing steps such as hot rolling, singeing, and coating. This filter material boasts high porosity, excellent air permeability, and an extremely wide range of applications. It exhibits high chemical stability and can effectively filter not only ambient-temperature gases but also corrosive gases containing acids and alkalis, as well as water.
The outlook for the synthetic fiber felt industry is very promising. It offers numerous benefits to businesses when used, making it highly popular among customers. To help everyone learn more about this product, let’s now explore some interesting facts and insights related to it. I hope many people will join in and share their knowledge. Many people aren’t aware of the basic information about synthetic fiber felt, so as a manufacturer, it’s important for me to briefly explain: actually, synthetic fiber felt boasts exceptionally high strength. Short fibers have a tensile strength ranging from 2.6 to 5.7 cN/dtex, while its high-strength fibers can reach 5.6 to 8.0 cN/dtex. What we need to keep in mind when using it is that, due to its relatively low moisture absorption, its strength in the wet state is roughly equivalent to its strength in the dry state. It has an impact resistance four times higher than nylon and twenty times higher than viscose fiber. As you can see, synthetic fiber felt is remarkably elastic. Because its elasticity closely resembles that of wool, it’s said that when stretched by 5% to 6%, it almost completely recovers its original shape. Moreover, its wrinkle resistance surpasses that of other fibers—garments made from it remain wrinkle-free and maintain excellent dimensional stability. For these reasons, it’s widely used in various applications. Additionally, its modulus of elasticity is around 22 cN/dtex, which is two to three times higher than that of nylon. Polyester fabrics made from synthetic fiber felt exhibit superior strength and excellent elastic recovery, making them durable, wrinkle-resistant, and resistant to heat damage. As a manufacturer, we strictly adhere to rigorous quality management practices, earning the full trust and unanimous praise of our customers thanks to our high-quality products, innovative designs, reasonable prices, and comprehensive after-sales service.
Chemical fiber felt is actually rich in heat-resistant polyester and is produced using melt-spinning technology. The fibers in chemical fiber felt can be remelted by heating, making them thermoplastic fibers. Moreover, polyester has a high melting point and low specific heat and thermal conductivity; thus, polyester fibers exhibit excellent heat resistance and thermal insulation properties. Among synthetic fibers, chemical fiber felt boasts good thermoplasticity but relatively poor resistance to melting and scorching. Of course, this is largely due to the smooth surface of polyester and the tightly packed molecular structure within its interior. Polyester is a fabric with outstanding heat resistance among synthetic fiber textiles; it is thermoplastic and can be used to make pleated skirts, which are remarkably durable.
