Ablation Method of Grinding a Leather Split under the Influence of Laser Radiation

Abstract

Using scanning electron microscopy, the surface morphology of a split leather sample was studied under the action of laser radiation from the front and backsides. It has been established that the effect of laser skin resurfacing is achieved in the range of input energies of 40 J and exposure times of 40 sec. It was found that laser exposure from the front and backsides leads to polishing of splits. Skin resurfacing from the front and leather split starts at different input energies from the front side from the split, which is associated with a looser structure of the leather from the split and its lower absorption of radiation.
