3 Peculiarities of Textile Substrates and their Relevance to Wetting 

The characteristic and complex geometry of textile substrates has significant effects on the wetting behavior of a droplet as well as the appropriate method to characterize the wettability of a textile. 

A technical textile may be constructed as a non-woven structure of fibers - usually fibers are directly spun on a moving belt and form an 

According to the complex composition of fibers and yarns, four factors influence the wetting behavior of a droplet on a textile surface. 

Primarily, spreading is defined by the surface chemistry of the synthetic fiber. The vast majority of technical textiles are made of poly(ethylene terephthalate) (PET), polyamide (Nylon or PA), and poly(propylene) (PP), which can be categorized as more or less hydrophobic.
