Andritz Kusters Wet-Finishing for Diaper Spunbond

Tobias Schafer, Head of Sales for Andritz Kusters (Germany) commenced with market data for the Arab Maghreb Union (Algeria, Libya, Tunisia, Morocco and Mauretania), a region of MENA with 1.54 million babies born per year, mainly in Morocco and Algeria.  The birth rate is however declining.  

The diaper market is 55% penetrated with a potential of between 7 billion (according to John Starr) or 8.55 billion (according to EDANA) diapers/year.

Diaper performance is related to multiple insult strike-through times, wet-back and runoff from the coverstock.  These in turn are controlled by oil pick up in the hydrophobic finishing of the coverstock, a process which spreads 10 litres of finish over an area on nonwoven the size of a football pitch. Andritz have developed a new kiss roll applicator system with heated rollers for single or 2-sided coating.  Metered uptake and automatic concentration control guarantees precise wet pick up.  

Because of the air turbulence created by the fast moving spunbond in the kiss roll system a mesh structure is used over the rolls to reduce turbulence induced variations.  The new drum drier has two stages to allow hotter operation at the inlet side.  In-line oil uptake measurement with feedback to kiss roll speeds allows the  wet pick up to be controlled as line speed increases.
