Résumé : |
The requirements for textiles differ greatly depending on the area of application, whereby it often does not remain with only one required functionality. For example, in the field of functional clothing or protective clothing/PPE, it is necessary to protect the textile's wearers from UV radiation. At the same time, self-cleaning effects offer certain advantages in that field. In addition, an antimicrobial effect in functional clothing can reduce the formation of unpleasant odors, and in PPE — especially in the healthcare sector — can contribute to the interruption of the chain of infection. One way to achieve these 3 desired functions in just one finishing step is to immobilize titanium dioxide (Ti02). However,TiO2 is viewed critically for application in the textile sector due to a REACH listing. Another disadvantage is that it only takes effect under UV radiation and is therefore not suitable for indoor use. Alternatively, photocatalysts such as doped zinc oxides (ZnO) can be used, which also exhibit catalyticactivity through activation by visible light, which can lead to the killing of microorganisms and the degradation of organic soiling. |
