Currently, the methods to identify leather materials have limitations, and identifying natural types is also relatively complex. In this research, microstructures of four mammalian leathers (cattle leather, pig sheep deer leather), three kinds reptilian (crocodile lizard snake leather) regenerated were characterized by scanning electron microscopy. The spectral curves (from 900 1700 nm) these s...

Ecological pressures on chromium have now forced the leather industry to look for possible alternatives. A vegetablealuminum combination tannage has been studied, with special attention being given to intended final product. Aluminum is mineral tanning agents that are widely used to stabilize collagens in the leather industry. In this study, the crosslinking of vegetable and aluminum, with coll...

The growing awareness of the human and environmental vulnerability, to pollution resulting from industrial activity, highlights urgent need for control mitigate degradation world as we know it. leather industry, considered one industries with a significant impact, applies several chemicals, some them hazardous such chromium, in production. restricted EU regulations have driven search process th...
