At this year’s K Show, the Reifenhäuser subsidiary presents its newest developments for themarket: “Nonwovens are normally thin and smooth. Our High Loft Spunbond offers unique possibilities for themanufacture of thick, soft nonwovens that have the potential to unlock new areas of application for our customers,” commentsMichaelMaas, operations director research and development at Reicofil.

The hottest topic in the hygienemarket today is a strong demand for bulky and soft nonwovens. It is an Asian-driven trend with influence on the European and USA diapermarkets; these soft touch applications play an increasingly important role, especially in top sheet and back sheet applications wheremid-segment product ranges are being gradually squeezed out of themarket by premiumproducts.
Maas adds: “In the future, our customers will have to offer soft nonwoven products all over the world. It is critical to their businesses to adopt developments early and to be innovative.We already started years ago to develop the technology basis for softer products. Today we are able to offer various solutions for different customer needs. ”
