To provide a method for making a nonwoven fabric laminate having at least two nonwoven fabric layers.SOLUTION: There is provided a method for laminating two spunbonded nonwoven fabric layers to make a nonwoven fabric laminate. In order to make respective spunbonded fabric layers, continuous filaments are spun through at least one spinneret, then cooled and drawn and finally deposited on a deposition device to obtain a nonwoven fabric web. At least one first spunbonded nonwoven fabric layer 2 is made from a crimped multicomponent filaments, and at least one second spunbonded nonwoven fabric layer 3 is made from single component filaments. The single component filaments of the second spunbonded nonwoven fabric includes an elastomer based on polypropylene.SELECTED DRAWING: Figure 2 【課題】少なくとも２つの不織布層を有する不織布積層体を製造するための方法を提供する。【解決手段】２つのスパンボンド不織布を積層して不織布積層体として製造する方法であり、各スパンボンド不織布層を製造するために、連続フィラメントを少なくとも１つの紡糸口金で紡糸し、次いで冷却し、次いで延伸し、最後に堆積デバイス上に堆積させて不織布ウェブを得る。少なくとも１つの第１スパンボンド不織布層２はクリンプされた多成分フィラメントから製造され、少なくとも１つの第２スパンボンド不織布層３は単一成分フィラメントから製造される。第２のスパンボンド不織布の単一成分フィラメントは、ポリプロピレンをベースとするエラストマーを有する。【選択図】図２
