Abstract
A method for obtaining temporary non-stretchability characteristics, mainly in a machine direction, in a non-woven fabric having any level of stretchability, in order to ease converting is disclosed. The non-stretchability characteristics can be then eliminated in order to restore the original characteristics of the non-woven fabric. This technique allows the formation of final products comprising stretchable non-woven fabrics by converting machines.
