Technical Specifications
Parameters are a proposal starting point.
Final specifications are configured according to fiber type, product GSM, working width, required output and finished filter media.
Process Route
Fiber Opening → Blending → Carding → Crosslapping → Needle Punching → Finishing → Winding.
Opening & Blending
Fibers are opened, loosened and evenly blended to provide a stable material supply for downstream production.
Carding & Crosslapping
The fibers are carded into a uniform web and crosslapped to achieve the required GSM, width and thickness for consistent filter media.
Needle Punching
The layered web is mechanically consolidated into strong, uniform needle punched filter felt. Pre-needling, main needling or double-sided needling can be selected by product.
Finishing & Winding
Optional heat setting, calendering or lamination is added before the finished filter felt is wound into rolls for downstream processing.
