This is an initial step in the modification of Ahlstrom's - and the world's - largest wet-laid nonwoven line. This 4.5m wide line currently manufactures medical, apparel and a variety of other industrial nonwovens and will continue to have capacity to produce these products.
The project aims at freeing up additional capacity in order to produce materials using water-based chemistry, destined for the transportation filtration markets. Significant trial work has been conducted in the past month and commercial products are currently being brought to market. The line will still require further optimization in order to perform at the level of other current filtration media production assets.
'This line has an excellent track record of producing high quality products for the nonwovens industry utilizing water based chemistries, and we are confident it will be able to do so for the filtration industry', commented Randal Davis, Senior Vice President, Filtration. 'This additional capacity will allow us to support our customers' growth in both water-based and solvent-based chemistries as this move will consequentially give us the flexibility to free up solvent saturation capacity.'
The new capacity will be available in the first quarter of 2008.
Ahlstrom's Filtration business area is the leading manufacturer of filtration materials for Transportation, Air and Liquid filtration with 13 production sites across four continents.
