Abstract
Natural leather is widely used for car upholstery and has a non-flammability requirement. In the present work, bovine leather intended for upholstery for car seats are studied. Various technological schemes of tanning have been applied, including combined; various finishing methods have been applied and two flame retardants have been used, namely Firex LFS and Flacavon B-45. It was found that the studied methods of combined tanning of investigated leathers do not affect the colour fastness to dry and wet rubbing, but the highest total flame combustion time of the source is given by aluminium-chromium re-tanned leathers and this indicator decreases depending on the type of re-tanning of the tested samples in the following order: chrome, aluminium, vegetable. Flacavon B-45 showed higher efficiency in terms of flame retardancy of the investigated leathers.
