Polyester Needle Punched Filter felt
Polyester needle punched filter felt
Polyester needle felt is the most versatile, most cost effective and most widely used filter medium
for dust collection. It is strong, abrasion resistant, can work up to 150°C and has good resistance
to common acids, solvents and oxidising agents.
Disadvantages
Polyester's only real weakness is a tendency to hydrolyse at elevated temperature which means
that moisture can break down the fibres and cause them to revert to their basic constituents. This
results in powdering of the fibres and a serious loss of strength.

• Mining
• Cement Industry
• Iron and Steel Industry
• Aluminum and Non Ferrous Industry

It is easily resulted in the explosion and conflagration after the consistency of common industrial
powder and dust reaches the certain degree (explosion limit) if touching the static electricity light
and spark outside, such as flour powder, chemical dust, coal powder etc. In the field of the
dedusting filter bag, if we use the bag to collect dust, then the filter medium for bags must be anti-
static.
By combining the conducting fiber into the transversal yarn in the needle punched felt base cloth or

the stainless steel thread in the scrim.
Applications:
• Areas subject to explosion hazards,
For example, coal milling collecting

Polyester Oil-water Repellent Needle Felt
Oil-water repellent needle felt
Function of Oil-water repellent treatment: By use of compounds containing fluorine technology,
impregnate filter materials, the formation of molecular barrier around each fiber. To reduce the
critical surface tension of the fiber so that it can effectively resist the water-based and oily liquid
stains. Compared with ordinary fabric, these fabric have a more glamorous appearance quality, it
will also kind of like the lotus leaf has a great anti-oil, splashing water, anti-stain effect, can
effectively prevent oil, water, stains penetrate fiber inner layer, thereby maintain a long-term dry
fabrics, clean. This fabric is ideal for filtration of gases mixed with oil and moisture in south rainness
area of china.
This treatment can apply to almost all felt types.

PP Needle Punched Felt
PP needle punched felt
Polypropylene is a relatively low temperature fiber with quite excellent chemical resistance which
finds use in specialist applications such as the chemical industry.
The fibers cannot hydrolyze, the only chemical weakness being a susceptibility to oxidizing agents.
Other than that they can be used almost universally provided the temperature is below 90°C.The
fiber is of a low density (it floats in water) and so a given denier of fiber is much larger in diameter
than the polyester equivalent. This leads to felts being quite thick, almost 50% thicker than for the
same polyester weight. The fiber is very prone to static build up so the felts are often augmented by
the incorporation of either conductive fibers or a conductive scrim or a combination of the two. This
then helps to dissipate potential static electric discharges.
Features:
• Smooth surface, more defined pore size and good air permeability
• Low temperature resistance ( 88-110 ℃)
• Excellent resistant to hydrolysis, acids and alkalizes.
• Lower fiber release, Lower density, High mechanical characteristics
Applications:
• Galvanic industry and Chemical industry
• Pre-filtering solvents and acids
• Pre-filter to extend final filter life
• Final filter for noncritical filtrations
• Liquid-solid separation with strong acid and alkali conditions filter press
• Air filtration under 100℃
