| Résumé : |
From leather science, a deeper understanding of the theoretical basis of the tanning mechanism has unified the inorganic and organic chemistries of leather making processes. The ‘link-lock’ mechanism provides an explanation of present reactions and a tool for future developments. The question now posed is: where does this new thinking take us, in terms of the future of tanning? The answer is: into a paradigm shift. Chrome tanning will remain with us, but in the future it can be viewed very differently from its currently perceived technology. Options for transforming the process may now be proposed. Important in this exercise is to question closely the conventionally accepted features of the reaction. Alternative technologies for tanning in the modern era can now be developed, to make high hydrothermal stability leathers. Here, the link-lock theory has demonstrated that such outcomes cannot be achieved by any single conventional reagent, at least two tanning components are needed. Moreover, tanning can be more accurately formulated to match the chemistry (or biochemistry) of the reaction to the performance and environmental impact requirements of the leather. |
