Abstract:
A method of manufacturing a transversely stretched nonwoven fabric, comprising the steps of:stretching an original web comprising un-oriented filaments 1.2 to 3 times wider in a transverse direction of said original web at a temperature higher than its stretch suitable temperature by 5Â° C. or more; further stretching said original web stretched 1.2 to 3 times wider in said transverse direction at said stretch suitable temperature such that the stretched fabric has a tensile strength of 132.5 mN/tex or higher in its transverse direction to stretch said original web 7 times wider or more in said transverse direction in total as compared with the state before the stretch thereof for manufacturing a transversely stretched nonwoven fabric comprising said filaments of said original web aligned transversely.
