A laminated sheet which contains a cross-linking foam material, and radiates
far
infrared so that it has heat-insulating and heat-retentive properties. The laminated
sheet (1) has a three-layered structure including polyethylene foam (2)
having a sheet shape that is one example of a cross-linking foam material in which
a substance that radiates far infrared rays is mixed, non-woven fabric (3)
having a sheet shape formed on a lower face thereof and a polyester film (4)
formed on an upper face thereof. Since the laminated sheet of the present invention
is allowed to radiate far infrared rays, it can greatly shorten the snow-melting
time, etc., because of its heat reflection effects in comparison with a sheet made
of a single material of non-woven fabric, and it also makes it possible to greatly
improve heat-insulating and heat-retentive effects, and also to provide medical effects.
