Fibroline

What Fibroline does

Fibroline SA is a French technology and engineering company headquartered in Limonest, near Lyon, that has developed a proprietary portfolio of dry powder impregnation processes for functionalizing porous substrates. Its core technology uses high-intensity alternating electric fields to drive powder-form materials into textiles, nonwovens, papers, foams, and yarns without solvents, water, or drying steps, producing up to 100x fewer VOC emissions than solvent-based alternatives. The company monetizes this through four branded process configurations (D-Preg for industrial in-line roll-to-roll impregnation, S-Preg for low-content precise deposition in cleanroom medical settings, Y-Preg for technical yarns and tapes at speeds above 150 m/min, and T-Preg as a portfolio extension), backed by over 50 patents worldwide and more than €15 million of cumulative R&D investment.

The company serves four primary verticals: medical and medtech (wound dressings, hemostats, implants, diagnostic substrates), nonwovens and textiles (filtration, CBRN protection, insulation), composite materials (automotive, defense, aerospace prepregs and tapes), and technical yarns (gaskets, reinforcement yarns, conveyor belts). Named customers and partners include GATT Technologies (acquired by Ethicon), Howa Tramico, Navis TubeTex, DEPESTELE Group, and Euro Wipes. Its go-to-market is a hybrid B2B model combining direct sales of customized production lines, licensing-out of patents and know-how (often with technology transfer and after-sales support), and joint venture arrangements for specific markets or regions. A 2025 expansion through the Fibroline USA Innovation Lab with Navis TubeTex in Lexington, North Carolina, extends this model into the North American market.

Core offering

Fibroline develops and commercializes patented dry powder impregnation technologies (D-Preg, S-Preg, Y-Preg, T-Preg) that use high-intensity alternating electric fields to impregnate powders into porous substrates such as textiles, nonwovens, papers, foams, and yarns without solvents, water, or drying steps. The company monetizes these technologies through direct sales of complete production line machines, technology licensing and transfer agreements, joint ventures, and complementary engineering services including feasibility studies, product development, and industrialization support.

Product overview

Fibroline offers a portfolio of dry powder impregnation technologies for functionalizing porous structures including textiles, nonwovens, foams, and papers. The core technology uses high-intensity alternating electric fields to impregnate powder materials into substrates without solvents or water. The main products are D-Preg (industrial in-line process), S-Preg (low-content pattern deposition for medical use), Y-Preg (for yarns and tapes), and T-Preg (technology extension). These are complemented by innovation services including feasibility studies, product development support, and technology transfer/licensing programs. The company operates from its innovation center near Lyon, France, and has expanded to the US market through the Fibroline USA Innovation Lab partnership with Navis TubeTex.

Scale indicators9 records

Recent moves8 records

Expansion highlights6 records

Regional players

• Sefar Group: Swiss-headquartered manufacturer of precision fabrics, filter media, and screen printing fabrics for industrial applications. Comparable as a downstream user of functionalization technologies and as a potential partner/licensee for Fibroline's dry impregnation, especially in filtration applications in EMEA markets.

Emerging players

• Xericor Drying Technologies: Specialty industrial drying and impregnation technology company serving technical textiles, composites, and paper. Comparable as a niche provider of drying/functionalization equipment with overlapping customers in nonwovens and composites, though at a smaller scale than Fibroline.
• Hollingsworth & Vose: US-based manufacturer of advanced filtration media, battery separators, and industrial nonwovens. Comparable as a downstream user/adopter of impregnation technologies (including potentially Fibroline's MOF-enabled processes) for high-performance filtration — overlapping customer use cases rather than direct machinery competition.

Broad incumbents

• A. Monforts Textilmaschinen: Established German maker of textile finishing and coating/drying ranges used in technical textiles and nonwovens. Directly comparable as a competing machinery supplier in the same textile functionalization and impregnation value chain, though predominantly focused on wet/thermosol processes.
• Brückner Trockentechnik: A leading global manufacturer of textile finishing lines (stenters, coating, and impregnation machinery). Highly comparable to Fibroline as a competing supplier of impregnation equipment to the technical textiles and nonwovens industry, though much larger and offering wet-process-dominated portfolios that Fibroline's dry process aims to displace.
• Karl Mayer Technische Textilien: Global manufacturer of warp knitting and technical textile machinery, including for composite reinforcements. Comparable as a machinery peer serving similar technical-textile and composite-tape end-markets that Fibroline addresses with Y-Preg and D-Preg.
• Andritz Nonwoven & Textile: Large industrial group supplying nonwovens and textile processing lines including drying, bonding, and finishing. Comparable as a potential partner/competitor for nonwovens and technical-textile manufacturers evaluating impregnation upgrades, particularly in hygiene, filtration, and automotive substrates.
• Trützschler Nonwovens: German family-owned machinery specialist serving the nonwovens and man-made fibers industry. Comparable as a supplier of complete nonwovens production lines that may integrate impregnation/drying steps, positioning it as either a competitor or a channel partner for Fibroline's dry impregnation solutions.
• Voith (Nonwovens / Paper): Global machinery and process technology provider with significant nonwovens and paper lines. Comparable to Fibroline where customers evaluate impregnation/functionalization of paper and nonwoven substrates, particularly for filtration and industrial applications.

Direct peers

• Navis TubeTex: Lexington, NC-based leader in finishing machinery for the global textile industry and Fibroline's official US Innovation Lab partner. Directly comparable as a finishing-machinery counterpart with overlapping customer base; the partnership makes it simultaneously a peer and a strategic channel.
