Abstract: The object of a invention is the method for obtaining nubuck leather surfaces by the thermal correction of grain in wet condition in the phases of production prior to tannage. In the specified, selected, phase of processing starting from soaking and ending with the pickling process the whole leather grain is subjected to the action of high temperatures ranging from 80-250.degree.C. This thermal processing of the grain layer is carried out on equipment having a heating surface that permits attaining the temperatures mentioned above. The heating elements may be of the roller type (calenders or rolling mills) or flat plates (i.e. press). This equipment has to ensure contact of the whole grain surface with the heating element for 0.01 to 5.0 sec. Under the influence of high temperatures the protein keratohyalin layer is subjected to thermal denaturation.
