Parameter analysis of droplet impact of aqueous fluids onto textile fiber surfaces for advanced modeling of droplet-substrate interaction of textiles

Abstract

A number of structure parameters of textile surfaces and a number of jetting fluid parameters define the impact and spreading of aqueous droplets on textile fiber surfaces. Parameter and dimension analysis as well as advanced CFD and DPD modeling results provide data that form a basis for parameter analysis. Structure parameters and fluid properties have been varied in several computation runs. Experimental verification data on fluid distribution is shown for combinations of textile and model fluids.
