摘要

The change in the properties, such as tensile characteristics, compressional behaviour and air permeability, of a wide range of polypropylene heat-sealed spunbonded nonwoven fabrics has been studied after cyclic bursting pressure. It is observed that the cyclic bursting pressure results in change in tensile, compressional and transmission characteristics of fabrics to a great extent. The air permeability is found to be increased after the application of cyclic pressure, whereas the compressibility and recovery tendency increase marginally after the application of cyclic pressure. The cyclic bursting pressure also have significant impact on the tensile strength of spunbonded nonwoven fabrics. The tensile strength reduces after the application of cyclic pressure. The increase in the pressure level during cyclic loading significantly decreases the tensile strength.
