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.
Claims13
A method of making a nonwoven laminate having at least two nonwoven layers, the method comprising the steps of:
- spinning, cooling, and stretching first crimped multicomponent filaments to form a first nonwoven web;
- depositing the first nonwoven web on a deposition device;
- and
- spinning, cooling, and stretching, second monocomponent continuous filaments consisting of only one elastomer based on polypropylene with a mesopentad fraction of more than 70% to form a second nonwoven web;
- and
- depositing the second nonwoven web on the first nonwoven web and thereby forming the nonwoven laminate.
