A soft drapable nonwoven material having good bi-directional strength-stretch characteristics which is especially suitable for a sanitary napkin wrapper is described. The material comprises a web of staple length fibers such as a carded web having a predominant direction of fiber orientation and a pattern of adhesive lines serving to unite the fibers together into a coherent nonwoven material. The adhesive lines are uniformly spaced in the direction of fiber orientation and extend continuously across the web generally perpendicular to the direction of predominant fiber orientation. The adhesive lines are also disposed uniformly over the web in a regularly repeating oscillating pattern with the crests pointed in the direction of fiber orientation. The pattern period, line amplitude, and line spacing are carefully selected to insure that as the web is strained in the direction perpendicular to that of original fiber orientation web rupture is avoided over elongations of at least about 25 percent.
