Résumé :	Grain damage is one of the most common problems occurring in the tannery. The causes of grain damage are numerous and process control is important to prevent financial loss due to loss in quality. Damage to the grain results in a difference in shade and texture on the surface resulting in poor quality aniline leathers being produced. In finished leathers, areas of grain damage can result in a different uptake of finish components, giving rise to differences in shade and gloss. Once the causes are understood, the tanner can take preventative measures to avoid the problem. Grain damage occurs as a result of the grain being attacked by either physical or chemical methods. This usually occurs in the raw stock or during the early stages of processing. An understanding of the problem and its causes can help to eliminate the problem.
