Multi-purpose functionalisation of non-woven materials by means of an e-grafting process

Researchers at the FHNW University of Applied Sciences and Arts Northwestern Switzerland are developing a non-woven material with an innovative combination of functions by means of an e-grafting process.

Themes

E-grafting, functional surfaces

Objective

Industrial production of non-woven materials with functional surfaces.

Background

Based in Oberentfelden, Jakob Härdi AG produces non-woven materials for use in a variety of domains. Functionalised non-woven quilts that are easily wettable and have other interesting properties are in high demand for technical products. Possible applications areas include air-conditioning technology, incontinence products and outdoor equipment, for example.

Result

The research team developed the durable functionalisation of non-woven materials via the electron-beam-induced grafting (e-grafting) of polymers. After the material is coated, the e-grafting process involves the creation of long-lasting bonds between the substrate material and the functional graft polymer. Thanks to a new generation of electron-beam emitters, it is also possible to modify surfaces on an industrial scale using electron beams.
