Abstract : The surface and general hydrophilic characteristics of proteinic and cotton fibers were measured. The methods of selective wetting and of the non-dissolving volume were used. In the substances studied, a complete incongruity between the general and surface hydrophilic characteristics was found. Cases were discovered when the surface was hydrophobic while the substance was generally clearly hydrophilic (hair, feathers), and also cases were found when the surface was strongly hydrophilic while the substance was generally mildly hydrophilic (silk, cellulose fibers). The hydrophilic characteristics of the surface of fibrous substances give the most correct idea of their behavior during absorption processes. It is demonstrated that all methods of chemical treatment leading to an increase in the affinity of the surface of hair for water promote its more intense dyeing. Wettability measurements are a convenient method of controlling and studying such processes. (Author)
