Compressional behaviour has been studied during tensile loading with respect to mass per unit area, needling density, depth of penetration, wetting of fabric etc. Empirical equations for compression and recovery curves of needle punched nonwoven fabrics from jute, jute-polypropylene blend and polypropylene have been suggested and behaviours are described with two dimensionless parameters a and ß. A mathematical model has been developed relatin...
