Abstract: The individual and interactive effects of needling parameters (depth of penetration and punch density) and web parameters (fibre orientation, fibre linear density and fabric weight) on air permeability, compressibility, compressional recovery and bending length properties of hollow polyester needle-punched nonwoven fabrics have been studied using Box Behnken experimental design. Needle-punched fabrics have been made from cross-laid as well as parallel-laid webs. It is observed that as the web gets more consolidated, the compressibility decreases, recovery increases and stiffness generally increases. Finer denier fibres and parallel-laid webs lead to more consolidation in the fabric. Cross-laid structures show higher compressibility and lower recovery as compared to parallel-laid structures.
