Technologies / Coating / Special Fabrics Coating Lines

Special fabrics: a wide range of products for many applications in consumer and industrial sectors.

In combination with other materials, or used alone, special fabrics such as non-woven textiles are used to create a wide range of products for many applications in consumer and industrial sectors with diverse properties.

This diverse properties include: absorbency, liquid repellency, resilience, stretch, softness, strength, flame retardancy, washability, cushioning, filtering, bacterial barriers and sterility. Special fabrics are used in sectors like construction & filtration, healthcare & surgical, engineering materials…

Special fabrics coating line processes

At ILAMCO, we have developed important engineering & 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 & 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 & adhesives (hotmelt, permanent tack, water based, solvent based,…)
    • Hydrophilic & 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 dryers (also called air suspension)
    • Non-contact and sinusoidal web guiding
    • Special nozzles design ensure efficient energy transfer from both sides
  • Roller dryer
    • 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 / UVI hood systems
