The various types of fibers and mixtures of them used in modern fabrics have led to the development of a wide range of products, some of which are mixtures of products, each with different effects, which, above all, provide the required results.

For a leather to be waterproofed, it is necessary that the surface of the fibers and, above all, the surface of the elemental fibers, be covered with elemental products. Most of these products are heterogeneous compounds and the hydrophilic fatty component can precipitate and deposit around the fiber without chemical bonding.

They are molecules that have a polar/nonpolar (amphiphilic) structure, with a tendency to localize at the interface, forming a monomolecular layer adsorbed on said interface. Surfactant solutions turn out to be active by being placed as a monomolecular layer adsorbed on the surface between the hydrophilic and hydrophobic phases. This location prevents the traffic of molecules that go from the surface to the interior of the liquid in search of a state of lower energy, thus reducing the phenomenon of surface tension.
