Résumé : |
In the last decades several products have been applied to confer waterproofing properties to the leather: natural oils, alkenyl succinic acids, polysiloxanes, chromium soaps (stearates and oleates), phosphoric esters alone or in combination with alkenyl succinic acids and reactive agents or amphiphilic polymers. Other products (silicone derivative, fluorcarbonated resin) confer not only waterproofing but also oil repellent properties to the leather. In this work, the waterproofing behaviour of retanning-fatliquoring polymers alone or in combination with other hydrophobic products such as a silicone derivative and a fluorcarbonated resin is studied. The anionization of the tanned leather on the waterproofing performance of the retanning-fatliquoring polymer and the influence of the addition of fatliquoring auxiliaries to the tanning bath on the water repellent properties of the leather produced are also evaluated. A complete anionization of the tanned leather, by using a naphthalene sulphonic acid salt, is of paramount importance to obtain good water repellency. The addition of a sulphochlorinated paraffin and a phosphoric ester to the tanning bath reduced water-repellency values drastically. |
