Increased Oil Repellence of Technical PET Fabrics

The potential of discussed approaches for high oi7-repellence of technical fabrics made of PET and its impact in the field of aerosol filtration was evaluated in a recent study by the authors [49]. The objective of this study was to assess the performance of technical fabrics as drainage media in compressed air filters. Drainage layers are designed to take up the oil from 

In the context of an increasing demand for application-related functionalities rendering technical textiles (super-)hydrophobic or oleopho-bic has been one of the major topics of research and development in recent years. Besides the modification of surface chemistry in order to 

Given the increasing interest in physical processes with low consumption of chemicals, favorable environmental issues, and high controllability, the scope of this chapter was to give a short overview of fundamentals of combined photo-chemical and laser surface modifications and to exemplify the attainable effects by data obtained from experiments conducted by the authors. 

Reported examples cover the increase of water repellence of technical fabrics made of PET and p-aramid and the concept of highly oil repellent PET fabrics. In all cases the experiments impressively showed the synergetic effect of the combined treatment, which amplified the effects of the
