Under its Neumag brand,
Barmag will present its technologies for the production of nonwovens for filter
media at this year’s FILTECH. From June 30 to July 2, the company will be
represented at the Cologne trade fair in Hall 8, Booth E68.
The main focus is on
solutions for producing high-performance filter media at competitive costs.
Here, Neumag excels in both the meltblown sector and with its spunbond
solutions.
Meltblown technology for
the highest quality requirements
Neumag’s meltblown
technology enables the efficient and straightforward production of
high-performance nonwovens for filtration, insulation, and sorption
applications. A wide variety of polymers can be processed—from classic
polyolefins such as PP and PE, through PET, PLA, PBT, and PA, to specialty
plastics like PPS or TPU. All of these and other raw materials can be processed
safely and reliably using the Neumag meltblown process.
The hycuTEC hydrocharging
technology, which was honored with the Edana Filtrex Innovation Award, enables
the production of particularly high-performance electret filter media. This
allows the pressure drop of a typical FFP2 filter medium to be reduced to less
than a quarter. “Filtration efficiencies of over 99.99% are easily achievable
with standard media weighing around 35 g/m² and a maximum pressure drop of 35
Pa,” explains Andreas Frisch, Regional Sales Director Nonwoven. “Furthermore,
the additional drying step is eliminated in most applications—another advantage
of this innovative technology,” he adds.
Spunbond solutions for
high-performance filter concepts
Spunbond nonwovens are
becoming increasingly important in filtration—both as carrier materials and as
standalone filter media. By tailoring nonwoven structures specifically to the
task at hand, customer-specific requirements can be precisely met. It is also
possible to combine multiple functions within a single layer.
In particular, the
company’s long-standing expertise in bicomponent spinning processes opens up
new possibilities in the design of innovative nonwoven structures. The Neumag
Bico spunbond process allows for the combination of different fibre
cross-sections as well as the simultaneous production of different fibres from
one or more polymers on a single line. The spectrum ranges from classic
core-sheath and side-by-side filaments to split fibres and so-called mixed
fibres.
