Agents de tannage
AldéhydesUn aldéhyde est un composé organique, faisant partie de la famille des composés carbonylés, dont l'un des atomes de carbone primaire (relié au plus à 1 atome de carbone) de la chaîne carbonée porte un groupement carbonyle.
L'aldéhyde le plus simple est le formaldéhyde (ou méthanal), aussi appelé formol lorsqu'il est en solution aqueuse.
Un aldéhyde dérive formellement d'un alcool primaire (oxydation) dont le groupement hydroxyde -OH est en bout de chaîne et se forme suite à l'enlèvement de deux atomes H d'où le nom "alcool déshydrogéné" ou aldéhyde.

| Résumé : |
Exploring the application of natural biopolymers in leather manufacture is a need of the hour to achieve sustainability. The present research work explores the possibility of using modified biopolymer nanoparticles as a tanning agent. Starch, a polysaccharide with high functionalization, is converted into Nano Bio Aldehyde (NBA) through periodate oxidation as water-in-oil microemulsion method. The synthesized product was characterized by its physico-chemical nature. The prepared NBA shows an aldehyde content of 85%, which endorses its application as a tanning agent. Experimental leather trials were carried out to assess the tanning efficacy and found that NBA tanned leathers show a shrinkage temperature of 90°C. Physical characteristics of the experimental leathers were found to be 24 N/mm2 and 90 N for tensile and tear strength, respectively. The study provides a holistic understanding of modified biopolymer as a nano tanning agent to manufacture leather. |
