Penelitian penggunaan monomer n-butil akrilat untuk peningkatan mutu kulit secara iradiasi

Research on the utilization of n-butyl acrylate monomer for quality improvement leather by irradiation cobalt-60 gamma-rays is carried out as follows: Javanese crust hide was impregnated with water emulsions of n-butyl acrylate monomer for 2 hours, packed in to poly ethylene bags, sealed, then irradiated by cobalt-60 gamma rays (doses : 5 to 25 kGy). The irradiated leather was washed by water, dried and then physical tested. The results of physical test of leather modified with n-butyl acrylate showed the increasing of tensile strength and elongation, decreasing of water absorption, resistance against the flexing test of 20,000 times, and PH was constant. Organoleptic test showed that the softly of the modified leather was no different with unmodified leather.
