Se impregnaron cueros vacunos para capellada con 32 formulaciones acrílicas diferentes. Los resultados obtenidos indican que la emulsión acrílica y la concentración de humectante modifican notablemente la firmeza de lor, la absorción de agua y otras propiedades del cuero terminado. Por otra parte, las operaciones de planchado y reesmerilado del cuero impregnado revelan poseer gran incidencia sobre el quiebre de la flor y su extensibilidad a la rotura.

This study deals with the effect of different impregnating formulations on the properties of the finished upper leather. The variables investigated included the types of acrylic emulsion, the wetting agent concentration, the quantity applied and the concentration of solids. Both the acrylic emulsion and the wetting agent concentration were highly significant in determining leather break and other properties. On the other hand, plating and rebuffing operations had also affected the break and the distension at grain crack of the impregnated leather.
