Method for producing reticular nonwoven fabric

Abstract

An improved method for producing a reticular nonwoven fabric in which the velocity of the transversely stretching line step can be much increased by providing the transversely stretching step with a longitudinally orienting step, thereby accelerating the whole production line. The method of the invention includes the continuous steps of: a first feeding step to feed a first film material; a longitudinally stretching step to stretch the first film material; a splitting step to split the longitudinally the stretched first film material; a laterally spreading step to spread the split film; a second feeding step to feed a second film material; a longitudinally orienting step to orient the second film material; a transversely slitting step to slit the oriented second film material; a transversely stretching step to stretch the slit second film material; and a laminating step to laminate the first film material with the second film material.
