Carding short fibers to open completely
Overlapping net with good continuity
Proper depth of pre needling to avoid damaging the strength
The felt has good adhesion after main thorn and shaving
The corrosion resistance of the fabric can be improved by chemical impregnation, extrusion, de-hydration, drying, sintering and treatment
Stretching and setting is the guarantee the quality of filter material
Reasonable control of high temperature hot rolling and setting temperature
The slitter automatically cuts off, neat, stable size, no deviation
The slitter is used to cut, which provides the premise guarantee for the stability of bag size
Strictly confirm to Sewing standard
