| Résumé : |
The present work attempts to analyze the surface properties of crust leathers processed using different syntans of the type phenol-naphthalene formaldehyde condensate, phenol formaldehyde, melamine formaldehyde, gluteraldehyde, styrene maleic anhydride, acrylic polymer, sulphone and heterocyclic N-methylol. Contact angles of liquid drops on the leather surfaces have been used to evaluate surface energy, acidity, basicity, polarity, work of adhesion and surface roughness. The surface energy component showed that the control crust leather without retanning is practically monopolar basic with S- = 13.02 mN/m. Acrylic polymer retanned crust leather exhibited high basic character (carreS- = 33.15 mN/m), while phenol formaldehyde retanned crust leather had the least values (S- = 1.03 mN/m). The surface behavior towards rub fastness and adhesion of finish has been significantly altered by the retanning systems in leathers and showed a good correlation with the surface properties like surface charge, polarity, roughness and work of adhesion. |
