Abstract: The time dependent behaviour of compressional properties of different nonwoven fabrics has been studied. It is observed that after a compression-recovery cycle, if the fabrics are allowed to relax for certain time they tend to recover and the recovery from the deformed state increases with the increase in relaxation time. The time dependent effect is very little in case of heat-sealed nonwovens as most of the recovery is instantaneous. The number of compression-recovery cycles has marked effect on. the compressional behavior, particularly in case of needle-punched fabrics.
