Surface tension affects capillary length and stability calculations
Measurered by stability (A*) - Very stable repellent finish A*=10, normal stability = 5, barely stable = 1
Most common weave, 50% open area
1D or 2D? A 2D model is more accurate for plain weave fabrics where yarns intersect and create a true 2D geometry. The 2D model assumes every yarn of the weave is wetting. If one instead assumes half the yarns remain dry, the 2D model reduces to the 1D model. Experimentally, mixing 50% of each leads to the best fit with the data.
The chemistry of the coating applied to the fabric affects the contact angle of the liquid on the fabric. You can override the default contact angle if the material/liquid is not in the default list.
Contact angle between liquid and a smooth, solid surface of this chemistry. You can override manually if material/liquid is not in the default list.
Hierarchical coating is a model that assumes the coating has particles within it. Therefore, repellency is achieved by the fabric texture, the coating chemistry, and the particles.
