VACUUM INSULATING MATERIAL AND METHOD FOR PRODUCING THE SAME

摘要

Disclosed are a vacuum insulating material having excellent heat insulating performance, and a method for producing the vacuum insulating material. A vacuum insulating material (1) has a filler (2) and an outer covering member (3) having a vacuum inside and enclosing the filler (2). The filler (2) is obtained by laminating two or more fiber array layers wherein continuous long fibers composed of a thermoplastic resin are stretched and arrayed generally linearly in one direction. The long fibers in an array layer are arranged in a direction which intersects the direction in which the long fibers in an adjacent array layer are arranged.
