| Résumé : |
The composition of fatty spew on leather was determined by gas chromatography-mass spectrometry (GC-MS). Meanwhile, the volatile substances in the fogging test of leather were identified by GC-MS. With the combination of all the data obtained, it was found that the predominant components of fatty spew were palmitic acid methyl ester, oleic acid methyl ester and stearic acid methyl ester, and their relative content ratio is approximately 8 : 1 : 1. An interesting phenomenon was that no fatty acids are detected in fatty spew although they are commonly regarded as the origin of this defect. These facts strongly suggest that the fatty acid methyl esters existing in fatliquors are the main origin of fatty spew defect in leather, and also one of the probable contributions to fogging. |
