MULTILAYER NONWOVEN FABRIC AND METHOD FOR PRODUCING SAME

摘要

Provided are: a multilayer nonwoven fabric having spunbond nonwoven fabric layers and at least one meltblown nonwoven fabric layer, said multilayer nonwoven fabric having high strength and high resistance to water pressure; and a method for producing the multilayer nonwoven fabric. The multilayer nonwoven fabric comprises three or more layers, wherein the two outermost layers are spunbond nonwoven fabric layers, and at least one inner layer is a meltblown nonwoven fabric layer. The resin constituting the spunbond nonwoven fabric layers has a melting enthalpy (&Dgr;H) of 90 J/g or less, as measured from a melting enthalpy curve obtained by raising the temperature of the resin at 10°C/minute after maintaining the temperature at -10°C for 5 minutes in a nitrogen atmosphere using a differential scanning calorimeter (DSC).
