ABSTRACT:
A nonwoven thermal insulating batt is provided. The batt comprises structural staple fibers and bonding staple fibers, the fibers being entangled and substantially parallel to the faces of the batt at the face portions and substantially perpendicular to the faces of the batt in the central portion of the batt. The bonding staple fibers are bonded to the structural staple fibers and other bonding staple fibers at points of contact. Also provided is a method of making the nonwoven thermal insulating batt which comprises air-laying a web of structural staple fibers and bonding staple fibers with the fibers being entangled and substantially parallel to the faces of the web at the face portions and in an angled, layered configuration in the central portions of the web. The air-laid web is reconfigured such that the fibers in the central portion of the web are substantially parallel and perpendicular to the faces of the web and the fibers are bonded to stabilize the reconfigured web to form the nonwoven thermal insulating batt.
