Résumé : |
Among the innumerable alternative tannages that are currently exploited, the vegetable tannins and oxazolidine combination is one of the most promising options. In this study, an organic combination tanning process based on henna and oxazolidine for the production of upper leather is presented. Extract from the leaves of Lawsonia inermis (henna) obtained from Sudan has been utilized for tanning in combination with oxazolidine. It has been observed that this combination tanning, which employs 20% henna extract and 4% oxazolidine results in leathers with shrinkage temperature of 98oC. The differential scanning calorimetry data is in accordance with the observed shrinkage temperature. The change in the order of addition of henna and oxazolidine though showed marginal difference in thermal stability, but significant variations were observed in physical characteristics of leathers. Scanning electron microscopic analysis showed that leathers tanned first with oxazolidine resulted in better fibre splitting. Leather made from oxazolidine followed by henna resulted in relatively softer leathers compared to henna followed by oxazolidine tanning. Leather made from both the tanning combination systems meets the required strength characteristics for upper leathers. The manufacture of upper leathers using combination of henna and oxazolidine appears to be promising. |
