Nonwoven finishing treatments are generally used to modify fabric properties, this includes enhancing appearance, improving technical performance and delivering added value or functionality. Nonwoven treatments such as coating, chemical modification and particle inclusion are widely used by industry, however there are limitations to these treatments in terms of their energy usage, material occlusion and wastage. To address these limitations, NIRI has developed a rapid inline fabric functionalisation technique that enables covalent bonding of a broad range of compounds for many different applications. The technique is tailorable and can be adapted depending upon the required functionality, specific application and intended environment. The presentation will include examples of how NIRI has utilised the technology to develop wound dressings, blood filters and virus entrapment for PPE.
