Special fabrics Coating lines
In combination with other materials, or used alone, special fabrics such as nonwoven textiles are used to create a wide range of products for many applications in consumer and industrial sectors with diverse properties (absorbency, liquid repellency, resilience, stretch, softness, strength, flame retardancy, washability, cushioning, filtering, bacterial barriers and sterility).

Special fabrics Coating line processes
At ILAMCO, we have developed important engineering and process know-how in special fabrics Coating and manufacture customized coating lines adapted to specific requirements.
Winding
- Single or turret with flying splice at max. production speed.
- Shaftless (mostly used) or shafted.
- Roll diameters up to 1600 mm.
- Perfect winding accuracy according to material thickness/microns.
- Flying splicing systems for automatic turret unwinders and rewinder.
- Programmable tensions adapted to specific materials and web path.
Web Treatment
- Embossing with customized patterns.
- Primer on one or both sides of the web.
- Corona treatment.
- Specific tension control in multiple points of the web path (with tension handling elements such as dancer rolls or additional nips for tension isolation of line sections).
Coating
- Multiple coating materials depending on desired properties:
- Resins and adhesives (hotmelt, permanent tack, water based, solvent based…).
- Hydrophilic and hydrophobic water repellent.
- Binder stiffened.
- Fire/flame retardant.
- Anti-microbial/anti-bacterial.
- Anti-static.
- Biodegradable.
- Etc.
- Coating widths of a few millimeters up to 2200mm.
- Coating weights of 0.5 g/m² to 100 g/m².
- Coating media with a wide range of viscosities and different solvents:
- Water based.
- Solvent based.
- Solid 100% (hotmelt).
- Coating speeds of 0.1 m/min up to 400 m/min.
- Pre or self-metered coating methods.
- Coating systems:
- Mayer bar.
- Roll over roll.
- Rotogravure.
- Direct gravure.
- Offset roll.
- Curtain.
- Slot Die.
- Comma bar.
- Others variations.
Laminating
- Special laminating materials for new fabrics or construction market (hotmelt, PVC…).
- Single and multiple layer laminations for construction with special materials such as wood, rock wool, special fabrics, plastics (PVC…).
- Please visit our Special Fabrics Lamination section.
Drying
- Flotation drying modules:
- Contactless transport of the substrate through a sinusoidal effect generated by the arrangement of the air blowing nozzles.
- Special nozzles design ensure efficient energy transfer on both sides of the substrate.
- Drying modules with roller transportation:
- Driven or not driven guide rollers.
- Laminar air flow.
- High speed air nozzles.
- Water or solvent based coatings.
- Independent and sectorized regulation for air speed, temperature and recirculation in each drying hood and section to optimize drying performance and energy consumption.
- IR/UV hood systems.
- Heat generation systems:
- Gas
- Steam
- Thermal oil
