The economic and ecological benefits of ‘new’ coating techniques for textiles


Many classic coating systems require much energy and often have a serious impact on the environment. The decisive reasons to switch from traditional to new coating technology are often economic or ecological in nature. However, there are more benefits. Professor Marc Van Parys of the Hogeschool Gent will address them in more detail in his presentation ‘Coating technologies in textile: State-of-the-art and future perspectives’.

Today the textile sector mainly makes use of solvent and water-based coatings, and to a lesser extent 100% solid systems (powders - hot melts). VOC emissions and the damaging impact of substances such as DMF in solvent systems have a seriously limiting factor. Drying and curing steps in water-based systems require much energy and often result in a heavy ecological footprint (production waste and use of materials). These limiting factors also render traditional systems less flexible and versatile. 

Environmental and economic considerations are therefore also a factor in the growing interest of companies in switching from traditional to ‘new’ coating technology. On the one hand plasma, UV, magnetron sputtering and digital technology should make a sustainable use of resources (water, energy, chemicals) possible and on the other produce less waste and answer optimally and flexibly to new business models as well as encourage the innovation and engineering of new coatings. Moreover, the societal and social merits of this technology are also not to be ignored: better working and safety conditions for personnel on the work floor (less emissions and pollution).
