ABSTRACT:
A multilayer nonwoven thermal insulating batt is provided. The batt comprises a blend of bonding staple fibers and staple fill fibers, the fibers being formed into a multilayer batt. The bonding fibers are subsequently bonded sparingly to staple fill fibers at the points of contact to enhance the structural stability of the multilayer batt but allow delamination of the individual web layers under mechanical action. Also provided is a method of making a thermal insulating nonwoven multilayer batt comprising the steps of: (a) forming a web of bonding staple fibers and staple fill fibers such that the web has a substantially smooth side and a loose fibrous side; (b) forming a batt of multiple layers of the webs; (c) subjecting the layered batt to sufficient heat to cause bonding of the bonding staple fibers to other bonding staple fibers and staple fill fibers at points of contact within each layer and sufficient bonding between each layer to stabilize the batt yet permit delamination of the layers when the batt is subjected to mechanical action.
