After successive further development of the intensive needling technology, the DiloGroup has now succeeded in launching the MicroPunch technology for industrial scale. DiloGroup, Erbach/Germany, focusing on complete lines for processing staple fibers for web formation and needling, will draw attention to current requirements in nonwovens production with regard to environmental compatibility at the Index23 international nonwovens exhibition in Geneva/Switzerland from April 18-21, 2023.
Good abrasion resistance of intensely needled MicroPunch material allows the production of apparel, artificial leather, battery separators and filter media as well as medical and hygiene nonwovens with intense needling technology.
The production of comfort tissues with a weight range of 30-60 g/m² made from fine fiber blends using polyester and viscose has been a domain of the water-entangling technology so far. This product, being a typical disposable, is in the crossfire regarding sustainability and recyclability. Therefore, biodegradable or decomposable fiber material is the target for more environmental sustainability.
In addition, for the evaluation of a web consolidation process, low carbon emission and low energy consumption are important criteria.
The classic needling technology and its qualification for the production of lightweight nonwovens at low cost/kg has been technologically and economically proved in the meantime after many years of research work. It has become possible by an intense concentration of needles in the board and very fine barbs on these specialty needles which allow an economic mounting and quick exchange due to a new module design.
Compared to water-entangling lines, the MicroPunch needling line provides a considerable reduction in energy consumption.
In view of increased costs for electricity and gas, this reduced consumption has a great impact on the total cost/kg of finished product in many countries.
