DuPont Aircraft wipes : strength and versatility for a variety of aviation applications

Socomore is the European distributor for Sontara® AC, the wipers especially engineered by DuPont for the aircraft industry.



Now there’s a versatile new wipe specifically engineered to meet the toughest demands of aviation manufacturing and maintenance: Sontara® AC™ aircraft wipes from DuPont. Unlike rags and rental towels, Sontara® AC™ wipes are "The Clean Choice™"— manufactured in a patented process that delivers exceptional absorbency and low linting.

Sontara® AC™ aircraft wipes contain no metal particles and offer excellent wipe-dry that virtually eliminates streaking. And they hold tough solvents like MEK (Methylethyl Ketone) and MPK (Methylpropyl Ketone) without falling apart. Plus they’re manufactured without binders or glue that can break down and cause contamination. With new Sontara® AC™ aircraft wipes from DuPont, you’re cleared for take-off.

 

 
applications
wipers for polishing, repairing landing gear, manufacturing applications
  • polishing bright work (chrome, high-polish aluminium, etc)

  • leaves virtually no lint when wiping windshields and other flight-critical surfaces

  • repairing landing gear and engines

  • numerous aircraft manufacturing applications


Technology Sontara® / Sontara® Fabrics
Water jets + fibres Invented by DuPont
No chemical binder > Solvent resistant
Mechanically entangled > Wet strength Softness, drape
Water wash effect > Low linting
3D structure > High absorbent capacity
Choice of Wiping Materials
Laundered cotton wipes can release 10 million* particles when wiping a steel tray (* 30 x 30 cm tray, steel, applying 150 g on wipe, completely wet )
Choosing better materials can help reduce contamination
Selection Criteria for Wipes
Absorption:
Absorbency capacity : - Mass (g/g) - Area (ml/m2)
Absorbency rate : - intrinsic (ml/g/s) - extrinsic (ml/m2/s)
Strength : - Tensile - Burst - Abrasion
Textile characteristics : Softnessv Drapeability, Feel
Linting
Others : Color Size Packaging
The Aviation Industry Needs Sontara® AC™
  • Overriding concern for improving worker productivity.
  • Need for improved safety, production, and housekeeping.
  • Reduction in damage to parts produced and cleaned.
  • Continuing pressure to reduce cost.

  • Variety of prices - what user will pay
  • Laundry counts towels and charges high fee for those “lost”
  • Rental laundries cited by EPA study as environmental offender - contaminate water supplies, air….

Research on laundered wipes

Analysis on:
- heavy metals
- Extrable Organic Halogen content (EOX)
- pH
- conductivity
( compared to nonwovens)

> Results and conclusions
Heavy metals ~ x 10 nonwovensTNT
- high level of EOX
- pH high: risk of irritation
- dirty appearance
- contain metallic particles

Recommendation :

> Laundered wipes should be labelled as “possibly containing contaminants”

> Gloves should be used to protect the user!
