Filtration material
Needle punching production line
Filtration material
Full complete automatic nonwoven equipment specially developed for industrial filter media, adopting high-speed needle-punching entanglement technology as core. Double entanglement via pre-needling + main needling realizes 3D interweaving and entanglement of dedicated filter fibers, producing needle-punched filter media with stable structure and outstanding filtration performance without adhesive bonding.

Key Equipment
-
Dual-Bin Blending Feeder + Special Carding Machine for PTFEDual-bin feeder design realizes uniform blending of multiple fiber types and stable fiber feeding, solving uneven blending and feeding fluctuation to guarantee stable raw material and consistent filter quality in subsequent processes.
Specially designed for PTFE fibers (PTFE 3.5～5d×51～76mm; glass fiber 5～12μm×60～65mm), compatible with blended carding to solve PTFE web breakage and web leakage, anti-static, fine carding and stable operation. -
Needle LoomReciprocating puncturing by barbed needles realizes 3D interweaving and entanglement of web fibers, directly determining structural strength, porosity and filtration performance of filter media. Core equipment for mass production of various industrial filter felts and filter bags to guarantee filter quality.
