Olga Niculescu, Minodora Leca, Ciprian Chelaru, Laurentiu C. Dinca Absorption and Water Resistance of Natural Leathers Finished with Ecological Touch Emulsion in the Final Dressing

Abstract:

An ecologic emulsion for leather touch was prepared by emulsifying a mixture of beeswax, lanolin and triethanolamine monostearate stabilized with lauryl alcohol ethoxylated with 7 moles of ethylene oxide. It has a homogenous appearance and particle sizes ranging between 2 and 4 mm. Used in amounts of 20-100% in polyurethane, nitrocellulose or acrylic final dressing, it improves feel and water resistance of finished leather. For a given amount and time, this wax emulsion leads to lower amounts of water absorbed than a silicone oil emulsion used as control. The lowest values for water absorption in leather were obtained by adding the emulsion in polyurethane dressing, and the highest values - in acrylic dressing. Keywords: ecologic wax emulsions, leather finishing, final dressing, waxy feel
