NONWOVEN FABRIC CAPABLE OF BEING ELONGATED AND COMPOSITE NONWOVEN FABRIC COMPRISING SAID NONWOVEN FABRIC LAMINATED

摘要

A nonwoven fabric capable of being elongated which contains a fiber composed of at least two olefinic polymers, characterized in that the olefinic polymers are of the same type and exhibit different induction periods in flow-induced crystallization at the same temperature and at the same rate of strain in shear from one another; and a composite nonwoven fabric characterized in that it comprises at least one layer comprising the above nonwoven fabric.
