Chemical testing of leather - Volatile matter detection
[ 2023-12-05 ]
Leather refers to animal skin that has undergone physical and chemical processes such as hair removal and tanning, and is already denatured and not prone to decay. Leather is composed of natural protein fibers tightly woven in three-dimensional space, with a special grain layer on its surface, which has natural grain patterns and luster, and a comfortable feel. There are two popular types of leather products in the market: genuine leather and artificial leather. Synthetic leather and artificial leather are made from textile or non-woven fabric substrates, coated with polyurethane and treated with special foaming. They have a surface texture similar to genuine leather, but their breathability, wear resistance, and cold resistance are not as good as genuine leather.
