Fatliquoring: the heart of the wet end [premium content]
Fatliquoring is carried out to impart softness and flexibility to leather by adding lubricating products during wet end processing. The fatty matter introduced into the skin acts as lubricant, and helps the fibres to slide against each other. The process also improves the physical and mechanical properties of the leather.
