Sustainability, quality and efficiency are today’s requirements for systems solutions for filtration applications and their end products. These requirements are covered by the Oerlikon Nonwoven product portfolio. The company will be showcasing its meltblown and spunbond portfolio at the upcoming Filtech in Cologne/Germany from February 14-16, 2023. among other things, trade fair visitors will be able to find out more about the hycuTec charging unit, the 2022 Filtrex Innovation Award winner.
In the case of its hycuTec hydro-charging solution, Oerlikon Nonwoven, Neumünster/Germany, a brand of the Division Oerlikon Polymer Processing Solutions of Oerlikon Management AG, Pfäffikon/Switzerland, offers a new technology for charging nonwovens that increases filter efficiency to more than 99.99%. For meltblown nonwovens producers, this can mean material savings of 30% with significantly superior filter performance. Due to its very low water and energy consumption, the hycuTec is also a future-proof, sustainable technology, as the process can be used without any additional drying steps in the case of most applications.
The Oerlikon Nonwoven meltblown and spunbond technologies are very well suited for processing bio-based polymer PLA (polylactic acid), for example. To visualize this, the company will be presenting medical oronasal masks made from PLA, whose protective effectiveness and wear comfort are equivalent to those of conventional PP masks.
Spunbond products are becoming increasingly important in filtration applications – as backing materials for filter media and as the filter media themselves. The fact that the nonwovens’ structure can be tailored to specific tasks enables targeted, customer-specific requirements for various functions to be realized. Moreover, combining various functions in a single layer is also possible.
The bicomponent (bico) spinning process enables the creation of completely new nonwovens structures and hence the incorporation of various functions in a single material. The bico spinning process permits various fiber cross-sections, while standard virgin polymers, bio-based polymers and recycled polyester can be used as raw materials.
The Filtech 2023, the trade fair for innovation in the area of filtration and separation, will feature over 440 Exhibitors and a major international conference.
