FILTRATION & SEPARATION
AN IMPREGNATION TAILORED FOR THE FILTRATION SECTOR
Fibroline’s impregnation technologies are particularly well suited to the development of filtration applications. By taking advantage of the intrinsic porosity of nonwoven and textile structures, they allow active powders to be incorporated into the media, thereby imparting new functionalities such as capture, adsorption, absorption, or ion exchange.

Several types of adsorbent powders can be impregnated, such as MOFs (metal-organic frameworks), superabsorbent powders, zeolites or ion-exchange resins. The type and quantity of powder can be adjusted according to the species to be captured and the desired performance.
-
After impregnation, the resulting medium remains in a flat form, providing great flexibility for further processing and integration into various filtration systems. For instance, it is possible to produce pleated filters—commonly used in HVAC systems—, cartridge-type filter media for water filtration, or honeycomb structures. Layers can also be laminated onto either side of the impregnated product.
AIR FILTRATION
CO2 CAPTURE
Adsorbent powders with an affinity for CO2, such as certain MOFs or zeolites, can be incorporated into porous media using Fibroline technology. These functionalized media can then be used to capture CO2 from various gas streams, including industrial emissions or directly from ambient air.
ODOR CAPTATION
There is a wide range of adsorbent powders capable of capturing odor-causing molecules (such as MOFs or zeolites). Fibroline technology enables these powders to be integrated into porous media to develop functional filters designed to reduce or eliminate odors.
VOCs REMOVAL
​Fibroline technology enables the incorporation of adsorbent powders into filter media to capture VOCs (volatile organic compounds) present in the air. The choice of adsorbent can be tailored to the target molecules and the desired performance levels. This approach paves the way for numerous applications, particularly in the filtration and treatment of industrial gaseous effluents.
LIQUID FILTRATION
ION EXTRACTION
To extract ions from a liquid phase, filters can be impregnated with ion-exchange resins using Fibroline technology. Although these resins are typically used in bead form, Fibroline impregnates them as a powder, thereby increasing their specific surface area and enhancing their efficiency.
HEAVY METALS ELIMINATION
Fibroline technology also allows for adsorbent powders, including certain MOFs, to be incorporated into filtration media to capture contaminants present in liquids. Depending on the selected adsorbent, these media can be designed to target contaminants such as arsenic, mercury, or other heavy metals. This approach is of particular interest for the treatment and purification of water, as well as for the treatment of certain industrial effluents.
BLOOD FILTRATION
Fibroline’s solutions also enable the integration of functional powders into meltblown or spunbond nonwovens to impart specific properties for filtration or blood treatment applications. The choice of functional material and substrate can be tailored to the targeted species and the desired performance.
OTHER PRODUCTS
CBRN SUITS
​Additives in the form of adsorbent powders, such as zeolites or certain MOFs, can be impregnated into textile or nonwoven structures using Fibroline technology. These functional materials can be selected to capture various toxic chemical contaminants, including chemical warfare agents (CWAs). This approach enables the development of functional media intended in particular for personal protective equipment and filtration systems for CBRN protection.
OSTOMY POUCHES
​It is possible to impregnate adsorbent powders designed for odor capture into porous media. These functionalized media can then be incorporated into ostomy pouches in the form of membranes or filter layers to help manage odors generated by the device.
MOISTURE CONTROL
Powders with moisture adsorption and desorption properties can also be impregnated into nonwoven structures. The resulting functionalized media can help regulate humidity and reduce condensation in a given room. This functionality is particularly relevant for protecting moisture-sensitive electrical and electronic equipment.
