| Abstract: | Bursting
behavior of different polypropylene heat-sealed spunbonded nonwoven fabrics has
been studied under different pressure conditions and different mass per unit
area (50 - 300 g/m2). The spunbonded nonwoven fabrics are subjected
to number of bursting cycles at various levels of pressure and extensions. The
effects of rest time at peak pressure, number of pressure cycles, levels of
pressure and mass per unit area on bursting behaviour of spunbonded nonwovens
have been studied. It is observed that with the increase in mass per unit area
of spunbonded nonwovens the bursting strength as well as the extension on
bursting increase. Cyclic bursting loading, and time duration at peak loading
show significant effect of nature of bursting pressure and extension. With the
increase in number of cycles for constant value of bursting pressure, the value
of extension of same fabric increases. The level of pressure developed within
the nonwoven structure at certain level of extension depends on the mass per unit
area of nonwoven. |
