Abstract

Maximum load and percentage extension at break are the two most important mechanical properties of leather. They influence the performance and end-use applications of leather materials. An experimental investigation on the influence of testing lengths on the aforementioned mechanical properties of upholstery leather has been undertaken using rectangular and dumbbell shaped specimens in parallel and perpendicular directions to the backbone of upholstery leather. Results show that the tenacity and percentage extension values exhibit a decreasing trend with increase in test lengths. The experimental study on the influence of testing lengths on both tensile load and percentage extension at break is important from both fundamental and applied points of view. More importantly, it will enable the setting up of test methods and help with the quality control procedures in the leather industry.
