Optimizing elasticity and breathability performance of laser-cut ultrafine fibersynthetic leather fabric
Through modern laser cutting technology,ultra-fine fiber synthetic leather fabric with excellent elasticity and breathability performance is chosen.By combining theoretical analysis and experimental methods,the impact of different laser cutting parameters on variables such as tensile strength,elongation at break,and breathability of ultra-fine fiber synthetic leather is investigated.The results indicate that as the cutting thickness increases,the resilience of semi-cut fabric remains relatively stable,while the bending strength significantly decreases.Fully cut fabric exhibits much higher breathability than semi-cut fabric.Proportion combination experiments are conducted with a half-cut groove spacing of 4 mm and a warp-weft spacing of 3～4 mm.Through experimentation,it is found that the 1∶1 combination cutting fabric shows superior performance,making it the optimal ratio for designing ultra-fine fiber synthetic leather fabric.
