| Résumé : |
The influence of elastin degradation in leather on important mechanical properties was investigated. The elastin content of pelts and wet blues was determined by chromatographic analysis of desmosine, which is a specific and hydrolytically stable crosslinking. Analysis of pelts was performed directly, while chrome containing samples had to be detanned prior to analysis. It is demonstrated that elastase significantly reduces the elastin content. In contrast to often assured statements on the marked influence of elastase on softness, area yield, tensile strength and elongation of leather, our investigations showed no significant changes in the mechanical properties of leather as well as area yield, grain quality or softness after treatment with elastase. It is concluded that the impact of elastin on leather properties is generally lower than postulated before or that it is not pronounced in the dry state. |
