Polyimide Blended Needle Felt with Nomex base fabric

Our Polyimide Blended Needle Felt is a reinforced nonwoven filtration material made from 90% polyimide fiber and 10% pre-oxidized PAN fiber. The blended fiber web is mechanically needle-punched onto a meta-aramid plain-weave scrim, forming an integrated felt structure for industrial filtration applications.

This construction combines a polyimide-rich nonwoven layer with a woven supporting base fabric. The felt layer serves as the filtration medium, while the Meta-Aramid Woven Scrim provides structural support. Both layers are integrated through mechanical fiber entanglement during needle punching rather than adhesive lamination.

If you are sourcing Nonwoven Filter Fabric for high-temperature dust collection or filter bag production, this material can be evaluated against your operating conditions and finished filter design. We can discuss the required weight, thickness, width and roll specifications according to your application.

*The specifications listed above are proposed reference grades. The blended felt consists of 90% polyimide and 10% pre-oxidized PAN fibers, needle-punched onto a meta-aramid plain-weave scrim. Total weight is calculated from the nominal felt and scrim weights. Thickness values are preliminary estimates and should be confirmed through finished-product testing. Custom weights, scrim constructions and widths are available upon request.

Industrial Filtration Applications

High-Temperature Dust Filtration

This material can be evaluated as High Temperature Filter Media for industrial dust collection systems. Potential sectors include cement production, waste incineration, metallurgy, power generation and chemical processing.

Filter Bag Manufacturing

The material may be considered as Filter Bag Fabric for manufacturers developing filter bags for suitable industrial dust collection systems. Final suitability depends on the filter design, sewing and finishing process, operating conditions and performance testing of the completed bag.

Dust Collection Systems

As Dust Collector Filter Media, the felt can be assessed for selected baghouse and industrial dust filtration applications.

Industrial Filtration

Polyimide Filter Felt is intended for evaluation in industrial filtration applications where a polyimide-rich felt layer and meta-aramid woven reinforcement are required.

Aircraft Seat Fire-Blocking Layers

Polyimide blended needle felt can be evaluated as a fire-blocking layer for aircraft seat cushions and upholstery systems. Its inherently flame-resistant fiber composition makes it a potential material for thermal protection, while the meta-aramid woven scrim provides structural support.

Flame-Retardant Carpet Backing

The polyimide and pre-oxidized PAN blended felt can be considered as a flame-resistant backing or intermediate layer in carpet systems for hotels, theaters and other commercial interiors.

FAQ About Polyimide and Preox Blended Felt With Nomex Base fabric

What is Polyimide Blended Needle Felt?

It is a reinforced nonwoven filtration material with a felt layer made from 90% polyimide fiber and 10% pre-oxidized PAN fiber. The layer is needle-punched onto a meta-aramid plain-weave base fabric.

Is this a woven or nonwoven filter material?

The filtration layer is nonwoven. It is mechanically needle-punched onto a woven meta-aramid scrim, so the finished product combines a nonwoven felt layer and a woven supporting fabric.

What is the purpose of the Meta-Aramid Woven Scrim?

The scrim acts as the supporting base fabric within the felt construction. Its contribution to tensile strength and dimensional stability should be verified through tests on the finished material.

Is the product suitable for every high-temperature dust collector?

No single material is suitable for every dust collector. The selection of High Temperature Filter Media depends on operating temperature, gas chemistry, moisture, dust characteristics, filtration velocity and cleaning conditions. Please provide these details for evaluation.

Can this material be used as Filter Bag Fabric?

It can be evaluated for suitable filter bag manufacturing applications. The finished bag's suitability depends on its design, sewing, finishing, operating conditions and performance tests.

Can you customize the felt weight, thickness and width?

We can discuss the required weight, thickness, width and roll length. Please send your target specifications and estimated order quantity for confirmation.

Can you provide technical data and samples?

Available technical data and sample options depend on the selected grade. Please tell us which properties or test methods you need so we can confirm what documentation and samples are available.
