- ItemFree Energy Balance Of Polyamide, Polyester And Polypropylene Surfaces(Inda, 2012-01-01) Bachurová, Marcela; Wiener, JakubThe wettability of a solid surface is often characterized by the contact angle of liquid on the solid surface. The wettability is pertinent to surface energy, which is an important parameter. The wettability can be affected, for example, by the roughness of the solid surface. In our work textiles are used as macroscopic roughness surfaces, and smooth plate surfaces are used as well to determine surface energies. For the calculation of surface energies it is fundamental to know the contact angle. The advancing and receding contact angles are measured, and the relation between the hysteresis and surface energy is monitored.

- ItemTheoretical Model of the Influence of Textile Structure on Wetting Hysteresis(Inst Chemical Fibres, 2013-01-01) Bachurová, Marcela; Wiener, JakubIn our work we theoretically analysed the influence of textile structure on the hysteresis of wetting. The situation with current fabrics is complicated and the properties of fibers, yarns, and geometric arrangement also influence their wetting. The basis of the theoretical model is a simple plain weave fabric made from monofilaments. From this model we determined the real contact angle and apparent contact angle, and later we compared these values with results from the experimental measurement.
