Needle Felt for Liquid Filtration

Micron needle felt is a high-efficiency depth filtration material widely used in the field of liquid filtration. It is produced through a precision mechanical needle-punching process that intricately interweaves fibers to form a three-dimensional, porous non-woven filter medium. Thanks to its high porosity, low operating resistance, excellent dirt-holding capacity, and cost-effectiveness, micron-rated liquid filtration needle felt has become an indispensable, high-efficiency medium in industrial liquid filtration—representing a perfect blend of traditional and modern filtration technologies.

Typical Application Industries

  • Fine chemical solution filtration
  • Pharmaceutical industry: liquid clarification and impurity removal
  • Food and beverage filtration (syrups, alcoholic beverages, fruit juices)
  • Electroplating solutions and ultrapure water pre-treatment for the electronics industry
  • Industrial wastewater treatment and reuse systems
  • Oil-water separation and emulsion purification
