Zusammenfassung:PROBLEM TO BE SOLVED: To provide a laminated nonwoven fabric for a pipe-shaped covering material minimally losing its shape and easily handled in a site for use.SOLUTION: A laminated nonwoven fabric for a pipe-shaped covering material is a laminate comprising first and second fiber layers. The first fiber layer has heat shrinkage SHDat a temperature of 150°C of 5% or less, the second fiber layer has heat shrinkage SHDat a temperature of 150°C of 15% or more, and a difference in the heat shrinkage (SHD-SHD) at a temperature of 150°C between the first and second fiber layers is 10 to 50%. The first fiber layer has a unit weight of 30 g/mor more and less than 350 g/m, and the second fiber layer has a unit weight of 50 to 500 g/m.
