Production Process of Polyester Filter Media

production of polyester

Polyester Filter Media is produced by the following processes, opening, mixing, combing and evenly forming a net, then hot-melting, cooling and forming, and finally cutting into pieces or rolling. If the customer needs, the material can be glued or combined with cloth and net, and finally dried and shaped.

Features

  • It is resistant to the effects of chemicals such as chemical solvents and acid fumes.
  • Incremental structure. Using progressive encryption multi-layer technology, it can be blocked at different density levels according to the size of dust, and more effectively accommodate more dust.
  • It has the characteristics of high dust holding capacity and low resistance, and can be used repeatedly after vacuuming or cleaning.

  1. Blended Fabric: According to the different requirements of customers, the fiber is matched according to different proportions. After weighing the initial weight, it is poured into the mixer and rotated by the machine. The purpose is to stir all kinds of raw materials evenly.
  2. Opening: The stirred fibers are evenly spread and transferred to the licker device to be sequentially opened, and the fiber mass is subjected to strong opening, and then sent to the secondary opening device by the fan. After the fiber is double-opened, it is sent to the mixing box by the fan and mixed by the vibration of the bucket.
  3. Carding: Uniform thickness, evenly distributed cotton layer is transferred to the upper screen, and then spread by a rocking screen
  4. Laying: Swing back and forth by the shake screen, the material is spread into a uniform mesh layer and then sent to the oven from the bottom screen
  5. Hot Air Setting: A uniform layer of felt is fed into the oven, and the low melting point fibers in the oven at a certain temperature will hold the various fibers together to form a synthetic fiber cotton.
  6. Finishing: After the synthetic cotton is shaped by cold air, the thickness is determined by the pressing shaft, and then trimmed. When the length reaches the specified value, it is cut by the thermal fuse and then rolled.
