Streamlining for cost savings

At this week’s ITMA textile machinery show taking place in Barcelona, Trützschler Nonwovens has introduced its new Streamliner drum dryer which achieves much higher specific evaporation capacities than has previously been possible.

“The Streamliner’s optimised airflow with minimal pressure loss is combined with an optimised fresh air based on temperature-dependent density changes,” explains marketing manager Eric Schinnerling. “This and the heating system ensure an optimised flow technology, while energy efficiency can be increased by external air treatment and heat exchange.”

On today’s advanced standard-width spunlacing lines for nonwovens such as wipes, the company has calculated that as a result of the 30% less energy that this dryer makes possible, average savings of €410,000 a year can be achieved.

In drylaid nonwovens production meanwhile, the crosslapper stage of a line has turned into something of a bottleneck due to the high speeds of cards at one end and of the bonding and winding systems at the other.

Trützschler has aimed to remedy this with the development of its EKLB439 crosslapper. A number of new patents have been secured on its design, based on both new web guidance elements and the mastery of the dynamic factors influencing both process and machine.
