Zaradi narascanja svetovnega prebivalstva in posledicno vecje proizvodnje, uporabe in odlaganja polimernih materialov, je recikliranje le-teh postala nujnost . Polietilen tereftalat (PET) je v tekstilni industriji najbolj uporabljen sinteticni material, kljub temu pa je recikliranje PET-a iz tekstilnih materialov manj raziskano podrocje. V diplomskem delu smo PET vlakna depolimerizirali s postopkom nevtralne hidrolize, stopnjo depolimerizacije pa dolocili s pomocjo titracij. Rezultati so…
