Pengaruh penggunaan putih telur dan gelatin terhadap ketahanan gosok cat tutup

The aim of this study is to know the influence of the use of egg albumen and gelatin as a film forming or as a binder in making a finish to the rubfastness. For making a finish it was also needed Turkish Red Oil as a softener, direct dye as a colour and water as a solvent. In this research it was used 9 pieces of goat crust leather. They were then sided into 2 parts along the back bone. Part of them were coated on the grain with a finish made from 3% egg albumen, 1% direct dye, 0,5% Turkish Red Oil and 95.5% water. The other crusts were coated on the grain with a finish made from 3% gelatine, 1% direct dye, 0,5% Turkish Red Oil and 95.5% water. The films of the finishes were sprayed with formalin solution of 10% to be fixed, then they were dried and glazed. Furher the films of the finishes were tested for the rubfasteness using crock metre apparatus. Partical meaning of this research is, using 3% gelatin as film forming or as a binder for making a finish, the value of the rubfasness is higher than using 3% egg albumen.
