Abstract(s)
The process of transforming animal skin into leather comprises a range of chemical processes and mechanical operations that can be divided in four sectors such as beamhouse, tanning, dyeing, and finishing. In the dyeing sector, the chemical process (normally called retanning or dyeing process) has four main steps: neutralization, retanning, dyeing, and fatliquoring. A very important part of research in field of tanning industry is focused on develop and adapt alternative and clean processes, contributing to the sustainability of the planet. These new
processes and methods enable an improvement of the quality of the leathers obtained while achieving a reduction in the energy and water consumption, as well as pollution generated.
