Abstract

A nonwoven laminate having at least two nonwoven layers is made by first spinning, cooling, and stretching, first crimped multicomponent filaments to form a first nonwoven web that is deposited on a deposition device. Then second continuous continuous filaments including an elastomer based on polypropylene are spun, cooled, and stretched to form a second nonwoven web that is deposited on the first nonwoven web and thereby forming the nonwoven laminate that it then consolidated.
