Non woven filter fabric, also called nonwoven geo fabric, is the geotextile made with directionally or randomly orientated fibers, filaments or other elements by mechanically, thermally or chemically bonded process. Non woven geotextile fabric can offer optimum performance features including high tensile strength, puncture resistance, perfect acid and alkali resistance, excellent drainage and anti-aging properties etc. BPM nonwoven filter fabric is available in varying strengths and thicknesses to ensure appropriate material selection for your requirements. Nonwoven filter fabric is widely used for separation, filtration, drainage, protection and reinforcement functions in civil environmental engineering and construction projects.
What are the characteristics of Non Woven Filter Fabric?
High-efficiency nonwoven filter fabrics actively capture particles of various sizes while allowing fluids or air to pass through. Manufacturers design these fabrics to achieve specific filtration efficiencies tailored to particular applications.
These fabrics are crafted from a variety of fibers, including polypropylene, polyester, glass, and other synthetic and natural fibers, depending on the required chemical resistance, temperature tolerance, and other properties.
Nonwoven filter fabrics often exhibit good resistance to chemicals, making them suitable for use in environments where corrosive substances are present. This chemical resistance ensures that the fabrics maintain their performance even under harsh conditions.
Manufacturers engineer these fabrics to maintain their structural integrity under the stress of fluid flow or air passage, ensuring consistent filtration over time.
The pore sizes in nonwoven filter fabrics can be controlled during the manufacturing process to suit specific filtration needs, ranging from microfiltration to coarse filtration.
How to Choose Non Woven Filter Fabric?
Choosing the right nonwoven filter fabric involves several key considerations to ensure it meets your specific needs. Here’s a detailed guide to help you make an informed decision:
-
Identify Application Requirements:
First, determine the primary use of the filter fabric. Is it for air filtration, liquid filtration, industrial applications, or another specific purpose? Different applications demand different properties in the fabric.
-
Assess Filtration Efficiency:
Consider the particle size and type that need to be filtered. Nonwoven filter fabrics come with varying pore sizes and densities. For finer particles, opt for a fabric with smaller pores.
-
Evaluate Durability:
The longevity of the filter fabric is crucial. Look for materials that offer high tensile strength, tear resistance, and overall durability. Polypropylene and polyester are common choices known for their robustness.
-
Consider Chemical Resistance:
If the filter will be exposed to chemicals or solvents, choose a fabric that can withstand these substances without degrading. Polyester tends to have better chemical resistance compared to other materials.
-
Check Compatibility with Fluids:
Ensure the fabric is compatible with the fluid it will filter. Some nonwovens may absorb certain liquids, affecting their performance. Test samples under realistic conditions if possible.
-
Examine Thermal Stability:
For high-temperature applications, select a fabric that maintains its structural integrity and filtration efficiency at elevated temperatures. Polytetrafluoroethylene (PTFE) membranes are often used in such scenarios.
-
Review Maintenance Requirements:
Some nonwoven filter fabrics are easier to clean and maintain than others. Consider how often the filter will need replacing and whether it can be cleaned without significant degradation.
-
Budget Considerations:
While quality should not be compromised, it’s essential to balance performance with cost-effectiveness. Compare prices from different suppliers while ensuring the product meets your specifications.
-
Supplier Reliability:
Choose a reputable supplier known for consistent quality and reliability. Check reviews and ask for references if necessary. A reliable supplier can provide technical support and ensure timely delivery.
