Porous Fabric
Porous Bleeder
& Filter Cloth
Fabric
Taconic porous bleeder and filter cloth materials are engineered for applications requiring controlled air permeability, breathability, drainage, filtering, drying, or outgassing.
Unlike smooth PTFE coated fabrics, porous constructions allow airflow, vapor movement, or resin flow through the fabric surface while maintaining useful release and process performance.
Porous fabrics are used in composite processing, vacuum applications, drying systems, filtration-related processes, and industrial operations where controlled permeability and process release are important.
Performance Advantages
Why choose this
fabric construction?
Air Permeability
Porous construction allows controlled airflow through the fabric for breathable, ventilated, and permeability-dependent processes.
Outgassing
Supports vacuum, composite, and curing processes where gas, vapor, or trapped air must move through the fabric surface.
Drying Performance
Helps promote airflow, drainage, and moisture movement in drying systems and industrial process environments.
Process Release
Provides useful release behavior while maintaining the open, porous structure required for airflow and filtration-style applications.
Common Applications
Built for focused
industrial use cases.
Porous bleeder and filter cloth fabrics are used where airflow, drainage, breathability, filtration, vacuum performance, and outgassing support industrial processing.

Fabric FAQ
Common questions about
porous fabric.
What is Porous Bleeder cloth used for?
Porous bleeder cloth is used in applications requiring airflow, outgassing, drainage, drying, filtering, or controlled permeability.
How is porous fabric different from standard PTFE coated fabrics?
Porous fabric allows air, vapor, or liquid movement through the construction, while standard PTFE coated fabrics typically provide a smoother, less permeable release surface.
Where are porous PTFE fabrics commonly used?
They are used in composite processing, drying systems, filtration-related processes, vacuum applications, and industrial operations requiring breathability or controlled flow.
